Snakebites by venomous snakes in Brazilian serpentaria and zoos over a 10-year period (2012–2021)

Despite the wide range of institutions that maintain venomous snakes in captivity in Brazil there are no comprehensive data on the occurrence of snakebites and envenomations in these places. We examined the range of native and exotic species of venomous snakes kept by Brazilian zoos and serpentaria (scientific and commercial) and assessed the frequency of snakebites in workers handling these snakes during a 10-year period (2012–2021). Twenty-two (73.3%) of 30 institutions returned a standard questionnaire, including 15 serpentaria and 7 zoos that together kept 10,607 venomous snakes in 2022/2023. Commercial and scientific serpentaria had many more snakes (n = 10,550, consisting of 10,499 native specimens and 51 exotic specimens) than zoos (n = 57 native specimens), with two genera accounting for the majority of native species (Bothrops spp. = 84.5% and Crotalus durissus ssp. = 13.5%). Thirty-seven snakebites were reported and involved primarily the hands (33), seven of which occurred during venom extraction and 30 in other circumstances, most of them while handling/manipulating the cages or snake boxes (10) and restraining (9) or feeding (5) the snake. In addition, there were two cases of venom accidently sprayed on the face, including the eyes. Most bites were caused by Bothrops spp. (31), followed by C. durissus ssp. (4), Lachesis muta (1) and Micrurus corallinus (1). Thirty-three bites (89.2%) were treated with antivenom, with four bites to the fingers by Bothrops spp. resulting in local functional sequelae. There were 366,918 venom extractions with a ratio of 1.9 bites/100,000 extractions; no bites were recorded in the six institutions that sedated the snakes prior to venom extraction, which accounted for 22.7% of all extractions. These findings show that although snakebites are rare in Brazilian zoos and serpentaria, severe envenomation may occur. The occurrence of snakebites could be reduced by measures such as sedation of the snakes before venom extraction.

Survey the Occurrence of Globocephalus urosubulatus (Nematoda: Ancylostomatidae) in Wild Boars (Sus scrofa) in the State of São Paulo, Brazil.

Although previous studies have characterized the helminth fauna of wild boars kept in captivity in Brazil, records on these helminths in free-ranging animals are still scarce. In view of this, we aimed in our work to investigate the occurrence and morphological and morphometric characteristics of gastrointestinal helminths in wild Sus scrofa from the northwest region of the State of São Paulo, Brazil. The digestive systems of 10 animals (5 males and 5 females of different ages) were used in this study. Each anatomical segment was washed and sieved under running water, and the helminths were separated and identified using light and scanning electron microscopy, according to their morphological characteristics. A total of 2750 (1152 males and 1598 females) nematode specimens were collected from the small intestine of these wild boars, and all of them presented the morphological characteristics of Globocephalus urosubulatus. However, one characteristic is of particular interest because it has not yet been reported in the literature: a marked asymmetry between the lobes and their respective rays of the copulatory bursa, with the left one being larger than the right one. In this research, we identified the presence of G. urosubulatus in all the examined free-ranging wild boars and reported for the first time in the literature the asymmetry in the copulatory bursa.

Giardia nosode 30cH in the treatment of howler monkey (Alouatta guariba) with giardiasis in captivity in Brazil

The red howler monkey (Alouatta guariba) is an endemic primate of the Atlantic Forest, classified as vulnerable. They're susceptible to giardiasis, impacting human health and Alouatta genus conservation. Studies report parasite occurrence in wild and captive individuals. While asymptomatic infections are common in captivity, immunosuppression can lead to severe cases. São Paulo's Wildlife Division maintains a large captive population. To assess Giardia duodenalis presence, fecal samples were collected from 43 individuals in 17 enclosures over three days, totaling 153 examinations. Animals were asymptomatic, with some groups showing loose stools. Two processing methods (direct and Sheather) were used, followed by quantitative evaluation based on cysts per slide. Only one enclosure tested negative; others were rare (4), slight (8), or moderate (4). Despite being asymptomatic, treatment was chosen to prevent positive animals from spreading infection. Allopathic treatment was impractical due to enclosure size; homeopathic Giardia 30cH nosode was given via water and food for 15 days to 16 positive enclosures. Afterward, 144 fecal samples were reanalyzed over three days. Seven enclosures were negative, 8 were rare, one was slight, none were moderate. All had firm feces. Kruskal-Wallis test confirmed significant treatment (p=0.004). Giardia 30cH nosode reduced parasitism, environmental contamination, with easy administration and no stress/adverse effects.

Integrative taxonomy for the traditional coccidians (Chromista: Miozoa: Eimeriidae) from island canaries (Aves: Passeriformes: Fringillidae): Worldwide distribution, morphological and molecular characterization, revaluations and establishment of junior synonyms.

Island canaries Serinus canaria (Linnaeus) are finches native to the North Atlantic Islands, however, they have a worldwide distribution in captivity due to their relevance as a pet bird. Coccidians are the most reported parasites of passerines worldwide, both in the wild and in captivity, being frequently associated with disease in passerines kept in rehabilitation centers and commercial breeders. This study aimed to identify coccidians from island canaries kept in captivity in Brazil. Three hundred and fifteen genomic DNA extracted from fecal samples of island canaries from different breeders from Southern and Southeastern Brazil were used to perform a nested PCR assay to amplify a partial fragment of the 28S small subunit ribosomal RNA gene (28S) of Isospora spp. Microscopic screening and morphological identification of Isospora oocysts was performed in fecal samples corresponding to PCR positive DNA samples. Fecal samples have been formalin-stored for approximately four years. Positivity rate for both microscopy and PCR was 10.5% (33/315). Posteriorly, Isospora serini (Aragão, 1933) Box, 1975 and Isospora canaria Box, 1975 were morphologically identified from fresh fecal samples of island canaries maintained by a breeder in the State of São Paulo, Southeastern Brazil, providing a genotypic characterization via sequencing of the mitochondrial cytochrome c oxidase subunit 1 (COI) and 28S genes. The 28S and COI sequences referring to the morphological identification of I. canaria was, respectively, 100% and 99% similar to sequences deposited as Isospora serinuse Yang, Brice, Elliot & Ryan, 2015 from island canaries kept in a rehabilitation center in Australia. The COI sequence referring to the morphological identification of I. serini was 100% similar to a sequence of an extraintestinal Isospora, corroborating this identification/sequencing since I. serini is the first isosporan with an extra-intestinal cycle demonstrated. The comparison of morphological and molecular data from I. canaria and I. serini from this study with published data of Isospora spp. from canaries worldwide, allowed the specific identification from preliminary generic identifications, correction of misidentifications, as well as the establishment of junior synonyms. Finally, this study provides morphological and molecular data that ensure the correct identification of the two Isospora spp. from island canaries in future studies worldwide.

Infections by entomopathogenic fungi in common green iguanas (Iguana iguana) in captivity in Brazil

Entomopathogenic fungi, widely available biological agents used to control agricultural pests, are sporadically reported to cause focal or disseminated infection in reptiles and mammals, including humans. This study summarizes the clinical presentation, histopathological and molecular findings by panfungal polymerase chain reaction and sequencing of four cases of hypocrealean fungal infections in captive common green iguanas (Iguana, iguana). One case of granulomatous pneumonia, hepatitis and serositis was related to Metarhizium flavoviride complex infection. Two disseminated fungal infection cases, with scarce inflammatory cell infiltration, were caused by Beauveria bassiana while there was one case of multifocal granulomatous and necrotizing pneumonia by Purpureocillium spp. To the best of our knowledge, this is the first report of fatal mycosis infection due to entomopathogenic fungi in captive common green iguanas.

Quantitative genetic analyses provide parameters for selection and conservation of captive Great-billed Seed-finches (Sporophila maximiliani).

The Great-billed Seed-finch (Sporophila maximiliani) is an endangered South American bird that has suffered from trafficking and the destruction of its natural habitat. In contrast, there are over 180,000 Great-billed Seed-finches legally raised in captivity in Brazil. The interest as a pet for Great-billed Seed-finches is due to their exceptional ability to sing. In the present research, the unknown genetic structure of the Great-billed Seed-finch captive population was investigated by quantitative analysis of 6,226 pedigree records. Additionally, 7,671 phenotypic records were available to estimate genetic parameters such as heritability and evolvability of a song-related trait of these birds for competitions. The captive Great-billed Seed-Finch population faces many of the problems commonly encountered in domestic animal populations such as a high level of inbreeding (average of 8.26%, 70.47% of birds were inbred), pedigree bottlenecks, unbalanced contribution of breeding animals and structuring (equivalent number of subpopulations of 2.91). Despite this, most genetic diversity remains preserved within aviaries. The high generation interval (5.74 years) found for this population should help to prevent a rapid increase in inbreeding and genetic drift. These results should serve as strong motivation and support for urgent actions to manage the genetic diversity of captive Great-billed Seed-Finches. From the viewpoint of genetic improvement for singing time in tournaments (STT), this trait presents sufficient variability to allow response to artificial selection given the heritability of 18.7% and evolvability of 2,447%. In contrast, inbreeding and high generation interval appear to be the most considerable barriers that may limit the genetic gain for STT. Widespread adoption of techniques such as optimal genetic contribution selection and implementation of routine genetic diversity monitoring via pedigree analysis and molecular tools can be crucial both in terms of breeding and conservation of genetic diversity of captive Great-billed Seed-Finches.

Influence of environmental enrichment on the behavioral variables of caged Hyacinth Macaws (Anodorhynchus hyacinthinus)

The Hyacinth Macaw (Anodorhynchus hyacinthinus) is a species considered vulnerable by the IUCN Red List, and many individuals are found in captivity in Brazil. In captive environments, due to the lack of stimuli, these animals demonstrate abnormal behaviors due to a high degree of inactivity. Among the strategies to minimize this problem, increase the natural behavior, and improve the well-being are the techniques of environmental enrichment of the enclosure. In order to investigate the effectiveness of these techniques for this species, we evaluated two distinct phases: the time before and the time during the implementation of enrichment, using an ethogram. The method employed was based on the sample session by time interval, totaling 20 h per individual, per phase. As an enrichment, natural objects (branches, vines, and leaves) were assembled into mobiles, containing pieces of the animal’s daily diet. The electivity index was applied to compare the use of different quadrants and the different locations in the enclosure. The results showed greater exploration of the enclosure, a reduction of abnormal behaviors, and a decrease of inactivity. The quadrants were more used by both couples during the environmental enrichment phase and the decrease in the use of wire mesh was offset by the increase in ground use. In view of the results found, we conclude that environmental enrichment demonstrated to be an important tool in the management of captive hyacinth macaws, providing a better quality of life.

Hematological and serum biochemistry data on southern brown howler monkeys (Alouatta guariba clamitans) in captivity in Brazil.

Physiological values reflect the health condition and responses of individuals to handling in captivity. The aim of this study was to establish hematological and serum biochemistry parameters of clinically healthy animals of the Alouatta guariba clamitans subspecies. We collected blood samples from adult males and females kept at the Center for Biological Research of Indaial after chemical containment with 3.9mg/kg of tiletamine hydrochloride and zolazepam. Significant differences between males and females were found in the levels of erythrocytes, hemoglobin, hematocrit, lymphocytes, neutrophils, platelets, mean corpuscular hemoglobin concentration (MCHC), and gamma-glutamyltranspeptidase (GGT). Our results suggest the existence of sexual dimorphism in some physiological parameters of Aguariba clamitans. The parameters reported herein can be used as reference values for other populations kept under similar conditions.

Cryptosporidium spp. in Aratinga jandaia, Diopsittaca nobilis and Pionus menstruus in Brazil

Background: Cryptosporidium is an important protozoan in public health and veterinary medicine that often causes diarrhea in an array of hosts in developed/developing countries. Infection of the gastrointestinal system is the most common, but the respiratory system and other sites can also be affected, especially in birds and immunocompromised individuals. Transmission occurs through ingestion or inhalation of oocysts. The number of wild animals, including those in the class of birds, infected with this parasite has grown in recent years. This study aimed to report parasitism by Cryptosporidium spp. in captive-raised birds of family Psittacidae at the Rio City Zoo in Rio de Janeiro, Brazil.Materials, Methods & Results: Thirty-three pools of fecal samples of the species Amazona aestiva, Amazona amazonica, Anodorhynchus hyacinthinus, Ara auricollis, Ara canga, Ara glaucogularis, Ara macao, Ara manilapa, Ara maracana, Ara rubrogenys, Aratinga erythrogenys, Aratinga cactorum, Aratinga auerea, Aratinga mitrata, Aratinga auricapilla, Aratinga jandaia, Aratinga wagleri, Aratinga leucophthalmus, Brotogeris acuticaudata, Cynoliseus patagonus, Caracopsis vasa, Diopsittaca nobilis, Graydidascalus brachyurus, Muopsitta monachus, Nangayus nenday, Pionites melancephala, Pionites leucogaster, Pionus menstruus, Pionus chalcopteus, Pionus maxiliani, Pyrrhura perlata, Pyrrhura leucotis, and Triclharia malachitacea, kept in separate enclosures, were analyzed using Enzyme-linked Immunosorbent Assay (ELISA) for detection of parasitic antigens. Quantitative Polymerase Chain Reaction (qPCR) was conducted in order to identify the species Cryptosporidium in the positive samples targeting the small subunit ribosomal RNA gene (SSU rRNA), followed by sequencing and analysis of the DNA amplicons. Cryptosporidium spp. antigen was detected in three (9%) of the thirtythree pools assessed, corresponding to the following species of family Psittacidae: Jandaya parakeet (Aratinga jandaya), Red-shouldered macaw (Diopsittaca nobilis), and Blue-headed parrot (Pionus menstruus). Positivity of the three samples was confirmed by qPCR analysis, but it was not possible to identify the species of Cryptosporidium by this technique.Discussion: Zoonotic diseases, such as cryptosporidiosis, have been reported in wild and captive-bred animals worldwide. Several species of the class of birds are parasitized by Cryptosporidium spp. Infection in order Psittaciformes has been described in some species raised in captivity in Brazil; however, no reports of Cryptosporidium spp. infecting the following species of order Psittaciformes: Jandaya parakeet (Aratinga jandaia), Red-breasted macaw (Diopsittaca nobilis), and Blue-headed parrot (Pionus menstrus), were found in the specific scientific literature. The present study detected infection by Cryptosporidium spp. in three species of order Psittaciformes using ELISA and confirmed the positivity of the samples by qPCR, but the species of Cryptosporidium could not be identified. These infected birds should be carefully investigated, with identification of the species and analysis of their zoonotic potential, because they can be sources of environmental contamination and infection for the caregivers, visitors, and other animals of the Zoo. This is the first report of parasitism by Cryptosporidium spp. in these species of family Psittacidae in Brazil.

Inclusion of copepod Acartia tonsa nauplii in the feeding of Centropomus undecimalis larvae increases stress resistance

This research represents the first result of studies of the common snook Centropomus undecimalis larvae from broodstock matured in captivity in Brazil. The aim of this study was to evaluate if the inclusion of Acartia tonsa nauplii improves stress resistance of common snook larvae. The larvae were fed with: rotifers Brachionus plicatilis (10 to 15 mL-1); A. tonsa nauplii (0.25 to 0.5 mL-1) and rotifers (5 to 7.5 mL-1), and A. tonsa nauplii (0.12 to 0.25 mL-1). The average percentage of survival of the treatments was 11.9%. At 20 days of age, larvae were subjected to thermal stress. Subsequently, the stress resistance was evaluated. Common snook larvae fed B. plicatilis+A. tonsa reached a higher weight and length (7.5 ± 0.00 mg and 9.1 ± 0.23 mm, respectively) and resisted more heat stress (87.4%) than larvae fed other foods, indicating that the feed mixture is satisfactory as a starter diet for larvae of common snook. However, more research is needed to confirm these results.

Parasitological research in urine from marine manatees (Trichechus manatus manatus) maintained in captivity in Brazil

The marine manatee ( Trichechus manatus ) is one of the most endangered marine mammals in Brazil, and is currently classified as vulnerable to extinction. The main risks to the conservation of the species are from natural causes, such as the slow birth rate, human actions and infectious diseases. Among the main objectives of the National Centre for Research and Conservation of Aquatic Mammals, the Chico Mendes Institute for Biodiversity Conservation (CMA/ICMBio) is to promote scientific research and management actions for the conservation and recovery of endangered species of marine mammals, and develop and promote rehabilitation in captivity and release natural environment of the marine manatee. The passage of these individuals for captive is of utmost importance for the conservation of the species. The rehabilitation of captive cubs marine manatees and allow recovery and can return the animal to the natural environment, enables a greater knowledge of the species, referring to biological, behavioral and clinical. Studies on the parasitism of manatee in Brazil are few elucidated, more research related to the topic, it is necessary to better understand the disease and health aspects of the species. This work aims to realize the isolation of the parasite in urine samples of marine manatee kept in the rehabilitation process. All animals included in the study are from the rehabilitation center for wild animals CRAS/CMA/ICMbio , located in Itamaraca, State of Pernambuco. This deal is the first description of parasites in urine manatee in Brazil and can support management actions to be taken to ensure the health of animals in rehabilitation.

Yeast microbiota of natural cavities of manatees (Trichechus inunguis and Trichechus manatus) in Brazil and its relevance for animal health and management in captivity.

The aim of this study was to characterize the yeast microbiota of natural cavities of manatees kept in captivity in Brazil. Sterile swabs from the oral cavity, nostrils, genital opening, and rectum of 50 Trichechus inunguis and 26 Trichechus manatus were collected. The samples were plated on Sabouraud agar with chloramphenicol and incubated at 25 °C for 5 days. The yeasts isolated were phenotypically identified by biochemical and micromorphological tests. Overall, 141 strains were isolated, of which 112 were from T. inunguis (Candida albicans, Candida parapsilosis sensu stricto, Candida orthopsilosis, Candida metapsilosis, Candida guilliermondii, Candida pelliculosa, Candida tropicalis, Candida glabrata, Candida famata, Candida krusei, Candida norvegensis, Candida ciferri, Trichosporon sp., Rhodotorula sp., Cryptococcus laurentii) and 29 were from T. manatus (C. albicans, C. tropicalis, C. famata, C. guilliermondii, C. krusei, Rhodotorula sp., Rhodotorula mucilaginosa, Rhodotorula minuta, Trichosporon sp.). This was the first systematic study to investigate the importance of yeasts as components of the microbiota of sirenians, demonstrating the presence of potentially pathogenic species, which highlights the importance of maintaining adequate artificial conditions for the health of captive manatees.

Desempenho reprodutivo do beijupirá (Rachycentron canadum) capturado no litoral de Pernambuco

O desempenho reprodutivo de exemplares selvagens de beijupirá capturados no litoral de Pernambuco e aclimatados ao cativeiro foi avaliado durante 10 meses. Um plantel composto por duas fêmeas (peso de 14 a 16kg) e quatro machos (cerca de 12kg) mantidos em um único tanque de 70t produziu 48,7 milhões de ovos no período de outubro a junho. As fêmeas foram capazes de desovar 21 vezes, com uma frequência média (±DP) de uma desova a cada 11,9 dias (±2,9). Em média, cada desova produziu 2,4 milhões de ovos, com fertilização de 52,4%, o que resultou em aproximadamente 1,0 milhão de larvas por desova. Os resultados demonstram a viabilidade da metodologia empregada na formação do plantel e no manejo de reprodutores e confirmam a relativa facilidade de obtenção de desovas espontâneas do beijupirá em cativeiro. Também foi confirmado que o período reprodutivo dessa espécie em cativeiro se estende além do observado na natureza. Este é o primeiro relato sobre o desempenho reprodutivo do beijupirá em cativeiro no Brasil.

Genotyping of potentially zoonotic Giardia duodenalis from exotic and wild animals kept in captivity in Brazil

We have studied the variability of glutamate dehydrogenase (gdh) and small subunit ribosomal (SSU) rRNA coding genes of Giardia species in fecal samples isolated from wild and exotic animals in Brazil, and compared with homologous sequences of isolates from human and domestic animals characterized in previous studies. Cysts of Giardia duodenalis were obtained from feces of naturally infected monkeys (Alouatta fusca) (n=20), chinchillas (Chinchilla lanigera) (n=3), ostriches (Struthio camelus) (n=2) and jaguar (Panthera onca) (n=1). Assemblage AI was assigned to the unique isolate of jaguar. All the samples from monkeys, chinchillas, and ostriches were assigned to Assemblage B. There was little evolutionary divergence between the referred isolates and isolates described elsewhere. The Assemblage B isolates identified in this study were closely related to Assemblage BIV isolated from humans. The molecular identification of Assemblages A and B of G. duodenalis isolates from exotic and wild animals demonstrates that such hosts may be a potential reservoir for zoonotic transmission of G. duodenalis.

Molecular genetic analysis of the yellow-breasted capuchin monkey: recommendations for ex situ conservation

The yellow-breasted capuchin monkey, Cebus xanthosternos, is one of the most endangered species of the Brazilian Atlantic Forest. In situ conservation for this species is problematic due to habitat destruction; therefore, captive conservation has been considered as an alternative strategy. A Studbook for C. xanthosternos has been kept for more than 20 years; however, no genetic data has been collected. Our aim was to provide a preliminary assessment of the genetic variability of C. xanthosternos in captivity in Brazil and compare it with data from the wild. Microsatellite and mtDNA sequencing were carried out in 40 samples from five Brazilian institutions registered in the international Studbook and compared with 8 samples collected in a wild population from REBIO-Una/BA. DNA for analysis was extracted from hair, feces and blood. Our results showed that two of the five captive groups assessed had a genetic variability comparable to wild animals. However, the other three groups apparently require urgent management to improve its genetic variability. Considering that inbreeding effects are more pronounced in captivity due to lack of gene flow, our data indicate a need to increase population size by introducing newly rescued individuals into these captive groups. Our results are the first attempt to provide genetic information for captive C. xanthosternos in Brazil.

Molecular characterization of Cryptosporidium spp. from fecal samples of birds kept in captivity in Brazil

The aim of this study was to determine the prevalence of Cryptosporidium species and genotypes in birds kept in captivity in Brazil. A total of 966 samples from 18 families of birds was collected and stored in 5% potassium dichromate solution at 4 °C until processing. Oocysts were purified in Sheather sugar solution following extraction of genomic DNA. Molecular analyses were performed using nested-PCR for amplification of fragments of the 18S subunit of rRNA gene and of the actin gene. Amplification of Cryptosporidium DNA fragments was obtained in 47 (4.86%) samples. Sequencing of amplified fragments and phylogenetic analyses allowed the identification of Cryptosporidium baileyi in a black vulture ( Coragyps atratus), a domestic chicken ( Gallus gallus domesticus) and a saffron finch ( Sicalis flaveola); Cryptosporidium galli in canaries ( Serinus canaria), a cockatiel ( Nymphicus hollandicus) and lesser seed-finches ( Oryzoborus angolensis); Cryptosporidium meleagridis in a domestic chicken ( G. g. domesticus); Cryptosporidium parvum in a cockatiel ( N. hollandicus); Cryptosporidium avian genotype I in a canary ( S. canaria) and an Indian peafowl ( Pavo cristatus); Cryptosporidium avian genotype II in ostriches ( Struthio camelus) and Cryptosporidium avian genotype III in a cockatiel ( N. hollandicus) and a peach-faced lovebird ( Agapornis roseicolis).

Hans Staden's true history: an account of cannibal captivity in Brazil

In 1550 the German adventurer Hans Staden was serving as a gunner in a Portuguese fort on the Brazilian coast. While out hunting, he was captured by the Tupinamba, an indigenous people who had a reputation for engaging in ritual cannibalism and who, as allies of the French, were hostile to the Portuguese. Staden’s True History , first published in Germany in 1557, tells the story of his nine months among the Tupi Indians. It is a dramatic first-person account of his capture, captivity, and eventual escape. Staden’s narrative is a foundational text in the history and European “discovery” of Brazil, the earliest European account of the Tupi Indians, and a touchstone in the debates on cannibalism. Yet the last English-language edition of Staden’s True History was published in 1929. This new critical edition features a new translation from the sixteenth-century German along with annotations and an extensive introduction. It restores to the text the fifty-six woodcut illustrations of Staden’s adventures and final escape that appeared in the original 1557 edition. In the introduction, Neil L. Whitehead discusses the circumstances surrounding the production of Staden’s narrative and its ethnological significance, paying particular attention to contemporary debates about cannibalism. Whitehead illuminates the value of Staden’s True History as an eyewitness account of Tupi society on the eve before its collapse, of ritual war and sacrifice among Native peoples, and of colonial rivalries in the region of Rio de Janeiro. He chronicles the history of the various editions of Staden’s narrative and their reception from 1557 until the present. Staden’s work continues to engage a wide range of readers, not least within Brazil, where it has recently been the subject of two films and a graphic novel.
