Studies on prevalence and seasonal variation of gastrointestinal helminth parasites in Capra hircus and Ovis bharal from Sangamner tehsil of Ahilyanagar District (MS) India

The prevalence of gastrointestinal helminth parasite infections and associated risk factors was studied in traditionally reared East African short-horned zebu cattle in Lira District, Uganda. Fecal samples were collected from 205 cattle and coprologically examined for the presence of helminth parasites using the simple salt flotation method complemented with the sedimentation method. The overall prevalence of gastrointestinal helminth parasites (GITPs) in cattle in Adekokwok, Lira District, was 32.2%. Of these, 12 (18.18%) were cases of mixed infections mainly of Amphistomes and other GITPs. Paramphistomum was the most prevalent parasite contributing up to 45.5% of infections, followed by Fasciola, Toxocara, strongyles, Trichuris, and Nematodirus, in descending order of abundance. GITP infections were not influenced by the sex of cattle, while infection with Toxocara was associated with cattle age. The mean body condition score (BCS) for all animals studied was 2.37 ± 0.07. A low BCS was associated with gastrointestinal helminth infections. Nevertheless, other factors such as nutritional stress are likely to augment the effects of parasites in the traditional agro-pastoral system particularly in the dry season and should therefore be considered when using the cattle body condition as an indicator of parasitism.

Birds in a free environment carry huge risk of helminth parasite infections affecting the health of poultry and thereby indirectly leading to great economic loss. The present study aimed to evaluate the prevalence, intensity and species diversity of gastrointestinal helminth parasites (GIH) of country chicken (Gallus gallus domesticus) from local chicken markets of Visakhapatnam district, Andhra Pradesh. A total of 300 gastrointestinal tract (GIT) samples were examined from January to December 2021 and the collected parasites were separated, counted, identified and statistically analysed. The overall prevalence of infection was found to be 87% with an intensity of 139.29. The study showed high prevalence with mixed infections (66%), whereas the prevalence with individual groups i.e. cestodes, nematodes and trematodes was found to be 83.00%, 70.33%, and 0.67% respectively. Altogether 10 parasite species were identified viz. Raillietina echinobothrida being the most dominant with a prevalence of 72.67%, followed by Raillietina tetragona (62.00%), Heterakis gallinarum (59.33%), Ascaridia galli (45.33%), Davainea proglottina (43.00%), Amoebotaenia cuneata (42.67%), Raillietina cesticillus (38.33%), Hymenolepis sp. 1 (36.00%), Cotugnia spp. (29.67%) and the least was Hymenolepis sp. 2 (21.00%). In month-wise data, highest prevalence was recorded in July (100%), and the highest seasonal prevalence was recorded in summer (90%), followed by monsoon (87%) and winter (84%). No major significant difference in prevalence was noted between males (88.51%) and females (85.53%). Hosts with high body temperature and low GIT pH levels showed increased prevalence and parasite intensity.

SummaryRhesus macaques (Macaca mulatta) are distributed across Nepal in close association with humans and with a high probability of sharing of soil-transmitted intestinal helminth parasites. This study was carried out to determine the prevalence, richness and risk factors of gastrointestinal (GI) helminth parasites among rhesus macaques and humans in the Daunne Forest area, a community managed forest in the central mid-hills of Nepal. A total of 190 fecal samples, including 120 samples from rhesus macaques residing around the Daunne Devi Temple and in the surrounding forest, and 70 from local people, were microscopically examined by direct wet mount, floatation and sedimentation methods. Seasonal and age-sex based variations in helminth parasite prevalence were analyzed. Among the rhesus macaques, the total parasite prevalence was 39.2 %. Strongyloides sp. accounted for the highest prevalence (19.17 %) followed by Ascaris sp. (13.33 %), hookworm (10.83 %) and Trichuris sp. (4.17 %). Among the humans, Ascaris lumbricoides (11.3 %) was the only parasite detected. The Sorenson’s coefficient of similarity of GI parasites between the macaques and local people at the generic level was 0.4. Mean parasite richness for the macaques was 1.21 ± 0.41 (SD) per infected sample. Parasite prevalence in the summer season (41.4 %) was higher than in the winter season (36 %). Adult macaques (41.67 %) had higher GI parasite prevalence than the young (30.77 %) and infants (27.27 %). Among the adult macaques, the prevalence rate was significantly higher (P=0.005) in females (52.46 %) than in males (22.86 %). Our results indicate that the temple rhesus macaques have a high prevalence of GI helminth parasites and could pose a potential zoonotic risk. As such, the need for routine monitoring and an effective management strategy is essential.

Coprological studies on the prevalence of gastrointestinal helminth (GI) parasites in domestic ruminants from Srikakulam district of Andhra Pradesh, India, were carried out for a period of one year from January 2019 to December 2019. Fecal examination was done using direct smear, sedimentation and floatation methods. Altogether 3527 fecal samples were examined including 595 from cows, 485 from buffaloes, 1342 from sheep and 1105 from goat. Out of 3527 fecal samples examined, 1084 were found to be positive with three groups of gastrointestinal parasites (GI) showing an overall prevalence of 30.7%. Maximum infection was noted with nematodes (39.1%) and trematodes (37.3%), least infection was noted with cestodes (3.5%) and mixed infections were found to be moderate (20.01%). Host wise prevalence of parasitic infection has shown highest in the case of cattle recording 43.03%, followed by 40.8% in buffaloes, 29.4% in sheep, and 21.4% in goats. Total six varieties of parasites were recorded, the predominant being Haemonchus (Strongyle group) (29.25%), followed by Paramphistomum (25.5%), Fasciola (11.9%), Strongyloides (7.6%), Moniezia (3.5%) and Trichuris (2.2%). Season wise data on prevalence showed, high rate of infection in summer season (32.0%) when compared to winter (30.2%) and rainy (29.9%) seasons. Further studies are needed to design a rational for sustainable management of GI parasite infections in domestic animals of local regions.

Aim: To determining the prevalence of gastrointestinal helminth parasites among school children attending two community schools in Auta-balefi, Karu. Nasarawa State.
 Place and Duration of Study: The study was conducted between July and August, 2019 in two community schools in Auta-balefi, Karu Local Government Area, Nasarawa State, Nigeria.
 Methodology: Microscopic examination of faecal sample from 288 pupils (143 males and 145 females) from ages 5 years and above was carried out using formol-ether concentration technique. Questionnaires were also administered and only pupils whose parents gave their consents were enrolled in the study.
 Results: This study recorded an overall prevalence of 45.1% gastrointestinal helminth infection. The study however, identified the following parasites in descending order: hookworm (30.76%), Ascaris lumbricoides (25.4%), Schistosoma mansoni (17.7%), Strongyloides stercoralis (13.8%), Proglottids of tapeworm (10.78%), Fasciola hepatica (1.5%). Males (51.0%) were more infected as well as children between the ages 11-15 years with (48.3%). Risk factors such as: The educational status and occupation (higher education and unskilled job) of the parents, use of water closet and use of well water and contact with soil were found to contribute to the prevalence of intestinal helminths infection in the study. This is because of the significant association of present of parasites and the prevalence of the parasites (P > 0.05).
 Conclusion: The overall prevalence of gastrointestinal helminths parasite at the end of the study was (45.1%) which is considered to be high compare to previous study carried on the related subject matter and also certain risk factors were considered to be the reason for such high observation. The prevalence in this study is one to be worried about considering the harm these parasites has on the health and livelihood of children who need to be healthy to carry out their everyday functions.

Gastrointestinal helminth parasitism is an important problem of livestock in many places of the globe. Despite the fact that the disease is one of the leading causes of economic losses, there is little information on the occurrence of the infection in cattle and sheep in Ethiopia. A cross-sectional study was conducted from June 2022 to February 2023 in urban and peri-urban areas of the Ada'a District with the objective of estimating the prevalence of gastrointestinal helminth parasites (GIHPs) in sheep and cattle and to assess the commercial anthelmintic utilization practices and associated risk factors in sheep and cattle. A total of 351 randomly selected fecal samples (192 cattle and 159 sheep) were collected from the rectum and examined using flotation and sedimentation. One hundred respondents were interviewed for questionnaire surveys on anthelmintic utilization practices. The overall prevalence of GIHPs (61.25%) was recorded during the study. Among the animals, 55.21% and 68.55% prevalence of the infection was observed in cattle and sheep, respectively. There was a statistically significant difference (P < 0.05) in gastrointestinal helminth parasite (GIHP) infection between the study animal species, breeds, body condition of the animals, and production systems. However, there were no significant differences in gastrointestinal helminth parasite (GIHP) infection (P > 0.05) according to sex and age of the animals. A higher prevalence of strongyle (55.34%), fasciola (13.48%), and moniezia eggs (10.69%) was recorded. According to a questionnaire survey, ivermectin was found to be the most used anthelmintic drug. This study addresses the challenge of anthelmintic resistance (AR) against currently available anthelmintics; highly prevalent parasitic infections are causing tremendous economic losses to the animal industry.

The prevalence of gastrointestinal helminth parasites of trade cattle were investigated in Aguata and Orumba South Local Government Areas (LGA), Southeastern Nigeria. Between February and May, 2017, 210 cattle were randomly sampled in Aguata (140) and Orumba South (70) LGAs. Characteristics of each trade cattle such as sex, breed and body condition scores were noted. Fecal samples were collected per rectum from the selected animals and were subjected to floatation and sedimentation techniques. The overall prevalence of gastrointestinal helminth parasites was 57.6% (95% CI = 0.509-0.643). Of the 140 cattle screened at Aguata LGA, 74 (52.9%; 95% CI = 0.446-0.609) were positive for gastrointestinal helminth ova while 47 (67.1%; 95% CI = 0.555-0.77) were positive out of the 70 cattle screened at Orumba South LGA. A variety of gastrointestinal helminth ova were detected including strongyle, strongyloid, Toxocara, Fasciola, Schistosoma, Moniezia and Paramphistomum ova. Four helminth ova detected in the study area were zoonotic. Strongyle eggs were the most prevalent eggs detected in single infections followed by Fasciola eggs. Mixed infections were more common than single infection. Body condition score was significantly associated (p < 0.0001) with the prevalence of gastrointestinal helminth parasites of cattle in the study area while sex and breed were not. It was therefore concluded that trade cattle in Aguata and Orumba South LGAs, Southeastern Nigeria were affected by variety of gastrointestinal helminth parasites including zoonotic helminthes. Thus, routine anthelmintic treatment, good management practices and public enlightenment on the zoonotic importance of helminth parasites is highly essential.

Parasitic infections are one of the factors limiting fish in the wild for sustainable productivity. The study was carried out to determine the gastrointestinal helminth parasite associated with Parachanna obscura and Heterotis niloticus and their prevalence concerning sex and size (length and weight). Sixty (60) fishes (30 H. niloticus and 30 P. obscura) were bought from fishmongers from the Anambra River. They were examined through dissection and observation of the alimentary canal under the microscope's objective lens. The overall prevalence of the parasites in Heterotis niloticus was 83.33%. The parasites recovered were Tenuisentis niloticus 16 (53.33%), Sandonella sandoni 8 (26.67%) and Capillaria species 1 (3.33%). There was no significant difference in the prevalence of gastrointestinal helminth among the sexes (p&gt; 0.05). However, the parasite species had a significant difference in prevalence (p&lt; 0.05). In P. obscura, the overall prevalence of the parasite was 73.33% and only one parasite species, Procamallanus species was recovered. There was no significant difference in the prevalence of gastrointestinal helminth among sexes (p= 0.096, p&gt;0.05) and fish size. Further studies are required to consider the probable zoonotic transmission of parasitic diseases from fish. It concluded that the prevalence of gastrointestinal helminth parasites of these species is high and this may affect the fish quality.

Cattle are Nigeria's most abundant type of livestock, accounting for 5.2 percent of the country's GDP. Feed shortage, limited knowledge of farmers in livestock production, nutrition, breeding, and parasitic disease are the various factors that decrease cattle production. Most of these parasitic infections are zoonotic, putting people's health at risk. This research aims to provide epidemiological data on the prevalence of cattle gastrointestinal parasites in the study area. A cross-sectional study was conducted from April to November 2021 to determine the prevalence of gastrointestinal helminth parasites affecting cattle in Bogoro LGA. A standard coprological method was used to analyze 200 faecal samples from cattle for the presence of gastrointestinal helminth eggs. All collected data were analyzed using SPSS version 24. A chi-square and logistic regression analysis were performed to evaluate the relationships between the dependent and independent variables. A total of 58 (29.0%) of the cattle sampled tested positive for one or more gastrointestinal helminth infections. Trichostrongylus spp. (10.0%) and Oesophagostumum spp. (3.0%) were most prevalent among the nematodes, while Fasciola spp (4.5%) and Schistosoma spp. (3.5%) were the most prevalent among the trematode. Moniezia spp. (1.0%) was the only cestode detected. The differences in the prevalence of gastrointestinal helminth infections to sex, age, and breed do not vary significantly. There is a statistically significant difference in the prevalence of gastrointestinal helminth infections in the class of helminth parasites (χ2 =31.29, df = 2, p = 0.001). The binary logistic regression analysis shows that the cattle are more likely to be infected with nematodes than cestodes [COR (95% CI): 21.00 (4.98-88.62)]. Considering the high percentage of gastrointestinal helminth infections, there is a need for proper control and preventative methods, such as strategic deworming of cattle and sound management practices, are required to reduce the parasitic burden and increase productivity.

Gastrointestinal parasites constitute a serious problem to poultry production in Africa. But often times they are usually ignored by the majority of farmers. Whereas, it is one of the major leading causes of ill-health and high mortality rates in the poultry industry. This study was conducted to determine the prevalence of gastrointestinal parasites of chicken slaughtered at the Jalingo market. A total of 500 gastrointestinal tracts of local chicken comprising of 250 from males and 250 from females were collected from the poultry slaughtering and dressing section of the Jalingo market, and screened for gastrointestinal helminths using the saturated sodium chloride floatation techniques. An overall prevalence of 28.6% (143/500) was recorded with a prevalence of 16.8% (84/500) in males and 11.8% (59/500) females. Nine different species parasites comprising five nematodes and four cestodes, were recorded. Nematodes were the most predominant intestinal parasite with a prevalence rate of 89 (62.2%). And Ascaridia galli 45 (50.5%) was found to be the most prevalent nematode. Other nematodes observed were Capillaria annulata 13.4% (12/89), Heterakis gallinarum 2.2% (2/89), Strongyloides avium 32.5% (29/89), and Syngamus trachea 1.1% (1/89) having the lowest prevalence. Railliatina tetragona 57.4% (31/143) was the most prevalent cestode recorded. Other Cestodes were Hymenolepis carioca 27.7% (15/54), Raillietina cesticellus 12.9% (7/54), and Davainea proglottina 1.8% (1/54). No trematode was recorded in this study. This study showed that nematodes and cestodes were the common helminth parasites in local chicken. There is therefore the need for educating the farmers on the impact of gastrointestinal parasite infection in chicken and the need to institute good management practices so as to reduce their effects on productivity. Sex of the chicken had no statistically significant difference (X2 = 6.12, df = 1; P &gt; 0.05) on the prevalence of helminths.&#x0D; Keywords: Prevalence, Domestic chicken, Gastrointestinal tract helminth, Jalingo, Nigeria

Poultry industry occupies an important position in the provision of animal protein and plays a vital role in the national economy. Helminthiasis caused by helminth parasites is one of the most common infections affecting health of poultry and indirectly leading to great economic loss among small livestock holders. The prevalence of gastrointestinal helminth parasites in Gallus gallus domesticus was studied from January 2017 to December 2019 in the parasitology laboratory of Zoology Department, Babasaheb Bhimrao Ambedkar University, Lucknow, India. In this study, a total of 557 domestic fowls were examined to identify the different types of gastrointestinal helminth infections. During regular examination of helminth parasites, the highest prevalence was observed for Ascaridia galli (41.7%), followed by Cotugnia diagnopora (17.6%), Raillietina tetragona (11%), Heterakis gallinarum (7.4%) and Raillietina cesticillus (6.64%). In the monsoon season, prevalence was found to be higher than the summer and winter. Females were found to be more infected than the males. There was no trematode infection detected during the study period. The gross pathological lesions were observed in case of Heterakis gallinarum infection. The results of this study suggest that both nematodes and cestodes are prevalent in domestic fowls in the studied area.

Aim: One of the constraints of fish in the wild for sustainable productivity is parasitic infections. The study was carried out to determine the gastrointestinal helminth parasites associated with Malapterurus electricus and their prevalence in relation to sex and size.&#x0D; Study Design: The study was a survey done to establish the type of gastrointestinal helminth parasites found in M. electricus.&#x0D; Place and Duration of Study: The specimens were collected from Anambra River between August and December 2018.&#x0D; Methodology: A total of thirty-two (32) fishes were examined through dissection and observation of the alimentary canal under the objective lens of the microscope. The chi-square test was employed to determine the possible association between parasite prevalence, the sexes, and size. Results: The overall prevalence of parasites was 56.25%. The parasites recovered were, Electrotaenia malapteruri (50.00%) and Tenuisentis niloticus (6.25%). The male specimens (18) recorded a prevalence of 66.67% while the female (14) recorded a prevalence of 42.86%. There was no significant difference in the prevalence of gastrointestinal helminths among gender (P=0.178, P&gt;0.05). The length group, 30 – 39cm had a 100% prevalence. Thus, a significant difference between the fish size and parasite prevalence was observed. The weight groups, 100 -199g, and 400 - 499g also had a 100% prevalence. However, no significant relationship was observed between fish weight and parasite prevalence. The intestine was infected with parasitic worms of the cestode and acanthocephalan species.&#x0D; Conclusion: This study showed that there is high prevalence of gastrointestinal helminth parasites in M. electricus and this may possibly affect the fish quality.

This study was conducted to determine the prevalence of gastrointestinal helminth parasites in Clarias gariepinus with the view of quantifying its helminthic burden in Abuja. The study was carried out in three area Councils of Abuja, Nigeria, between the months of April and August 2015. A total of 83 live fishes (Clarias gariepinus) which includes 28 males and 55 females were randomly purchased from local fishermen and were subjected to examination for gastrointestinal helminth parasites. The lengths and weights of the fishes were measured prior to dissection and the parasites recovered were identified. Results indicated that 56 of the examined fishes were infected with various species of helminth parasites, giving a prevalence of 67.5%. Parasites were identified as Procamallanus laevionchus (32.5%), Rhabdochona congolensis (18.1%), Polyonchobothrium clariae (10.8%), Allocraedium species . (3.6%) and Heterophyid flukes (2.4%). The highest prevalence was recorded for nematodes (50.6%) followed by cestodes (10.8%) and trematodes (6.0%). Worthy of note, was the recovery of Heterophid flukes in this study which have not been previously reported in Nigeria and pose a great zoonotic threat. It was observed that fishes of standard length range of 20- 30cm (82.4%) were more infected than those of 30-40cm (65.0%) and 40-50cm (61.5%). The highest prevalence of infection (78.6%) was recorded in fishes with body weight of 500-600g while the lowest (58.8%) was recorded in fishes with body weight of 600-700g. The males had higher percentage prevalence (67.9%) than the females (67.3%). The result of the study indicated that the association (P˂0.05) between the prevalence of infection, sex, length and weight of the host was not statistically significant (χ2= 0.00289, 2.24 and 1.55; degree of freedom= 1, 2 and 5 respectively). The helminths recovered were found to parasitize the stomach and intestinal lumen, the latter being more affected.

Gastrointestinal parasites are common parasitic agents of cattle across the world, causing both clinical and subclinical parasitism that causes massive financial losses. The aim of this research was to assess the prevalence and risk factors for Gastrointestinal tract (GIT) parasites in cattle in Sumedang Regency, West Java, Indonesia. Between October and November 2022, 105 cattle had been chosen at random. The sex, breed, age, frequent deworming, cleaning frequency, and management system of each beef cattle were recorded. Fecal samples were obtained through rectum from the selected animals and submitted to flotation and sedimentation procedures. Overall, the prevalence of gastrointestinal helminth parasites was 47.62% (95% CI = 0.3791−0.5733). Strongyle-type eggs (STE), Strongyloides spp., Trichuris sp., Moniezia spp., Fasciola sp., and Paramphistomum sp. ova were found. 38.09% of the total samples were positive for Strongyle eggs infection and commonly seen in single infections, followed by Eimeria spp. infection. Mixed infections were found in 25 cattle, with double to multiple parasite infections. As a result, it was determined that beef cattle in Sumedang Regency in Indonesia were infected with a variety of gastrointestinal helminth parasites. Thus, frequent anthelmintic treatment, excellent management techniques, and public education about helminth parasites are critical.

Livestock farming has significant economic importance to the Nepalese society. Gastrointestinal helminth parasitism in buffaloes possess a warning for poor growth, milk production and, development. Thus this study aimed to study the prevalence of gastrointestinal helminth parasites in slaughtered buffaloes in Bhaktapur Municipality. Faecal samples (100) and visceral organs (100) i.e. small intestine, large intestine, rumen, and abomasums of 100 slaughtered buffaloes were collected and preserved in 2.5% potassium dichromate and 70% alcohol, respectively. Faecal samples were processed via direct and concentration techniques whereas organs were examined macroscopically for adults. The result showed an overall prevalence of 51% of helminth parasites. Paramphistomum sp. from the rumen and Oesophagostomum sp. from the large intestine were collected from the macroscopic examination. Altogether ten genera of helminth parasites were reported and among them, Paramphistomum sp. (18%) was found to be the dominant parasite in faecal examination followed by Fasciola sp. (16%), Oesophagostomum sp. (11%), Strongyloides sp. (7%), Haemonchus sp. (5%), Schistosoma sp. (3%), Capillaria sp. (2%), Cooperia sp. (2%), Trichostrongylus sp. (1%) and Syngamus sp. (1%). Single infection was prevalent in comparison to multiple infections in both examinations. Buffaloes were imported from Nepalgunj, Birgunj, and Jitpur whereas the location-wise prevalence showed no significant difference. Furthermore, awareness programs among butchers and farmers of farming places from where buffaloes were brought were involved to reduce parasitic loads among slaughtered buffaloes.
