Evcil Tavşanlarda Sindirim Sistemi Parazitlerinin Yaygınlığının Araştırılması

Bu çalışmanın amacı Kırıkkale ve Ankara yöresinde yetiştiriciliği yapılan evcil tavşanlarda sindirim sistemi parazitlerinin yaygınlığının araştırılmasıdır. Çalışma sırasında 100 adet tavşan kafesinden dışkı örnekleri alınmıştır. Her kafesten alınan dışkılar kafes içerisindeki tavşan sayısına bakılmaksızın tek örnek olarak değerlendirilmiştir. Alınan örnekler Fülleborn flotasyon tekniği ile incelenmiştir. Muayene sonucunda incelenen 100 dışkı örneğinin 44 tanesinin (%44) en az bir parazit türü ile enfekte olduğu saptanmıştır. 44 pozitif örneğin 40 tanesinin tek, 4 tanesinin ise iki parazit türü içerdiği tespit edilmiştir. İncelenen dışkı örneklerinde protozoonlardan Eimeria spp. ookistlerine, helmintlerden Passalurus ambiguus ve Trichostrongylus spp. yumurtalarına rastlanmıştır. Bu çalışmada Eimeria spp., %34, P. ambiguus, %2, Trichostrongylus spp., %4, Eimeria spp.+ Trichostrongylus spp., %3 ve Eimeria spp.+P. ambiguus %1 oranında tespit edilmiştir. İki veya daha fazla tavşanın bir arada bulunduğu kafeslerden alınan örneklerde parazit varlığı (%88.1), tek tavşanın barındırıldığı kafeslerden alınan örneklere göre (%12.1) istatistiki olarak daha yüksek bulunmuştur. Bu çalışma ile yörede hobi ya da ekonomik kazanç amacıyla yetiştiriciliği yapılan evcil tavşanlarda sindirim sistemi parazitlerinin yaygınlığı ilk defa belirlenmiştir.

Molecular identification of Eimeria species in liver and feces of naturally infected rabbits in Japan.

Among the 11 species of Eimeria in rabbits, some of which are known to be pathogenic and cause enteritis, E. stiedae induces severe liver lesions resulting in elevated mortality. Unlike in other countries, the incidence and prevalence of the parasites in rabbits have not been reported in Japan. In the present study, we histopathologically analyzed hepatic coccidiosis in a rabbit and attempted several primers to genetically identify the parasites and investigated the prevalence of Eimeria species at the same farm. In the liver of the affected rabbit, we observed fibrosis and edema around multiple bile ducts and epithelial cell hyperplasia of the bile ducts. Large numbers of developing parasites of Eimeria spp., mainly oocysts, were present in the bile ducts. PCR and sequencing analyses with the published primers for Cyclospora and Eimeria spp. were used to successfully identify the parasites in the liver as E. stiedae. The oocysts of Eimeria spp. were detected in 13 out of 20 fecal samples collected from other rabbits at the farm, and five Eimeria spp. (E. perforans, E. flavescens, E. exigua, E. magna, and E. vejdovskyi) were genetically confirmed. Our results provide the first indication that Eimeria spp., including highly pathogenic species, are present in Japan and the primer set used herein can be a useful tool for the identification of rabbit Eimeria spp.

Investigation of gastrintestinal parasites in rabbits of the species Oryctolagus cuniculus in the Northwest region of São Paulo, Brazil

Enteroparasites can be pathogenic for the rabbit population and for this reason, we have investigated its occurrence in bioterium of rabbits. The sample group was composed of 103 adult males of the species Oryctolagus cuniculus and New Zealand breed. Fecal samples (n = 103) were processed using the Willis Techniques (Fluctuation in saturated sodium chloride solution with specific density of 1.20 g/mL) and Faust (Centrifugal-flotation in zinc sulphate with density of 1.18 g/ml). The diameters of larger and smaller sizes of the sporocysts and sporozoites of the coccidia were measured by means of optical microscopy using the program CellSens 1.17_00_en_Rhine_13Feb2017. The Faust Technique showed positivity of 39.74% (31/78) for Eimeria spp, while in Willis Technique, 35.90% (28/78) was observed for Eimeria spp, being the species Eimeria perforans and in 51.28% (47/78) of them there was no parasitism. We identified, for the first time, the occurrence of the specie E. perforans in rabbits of the species O. cuniculus, New Zealand breed kept in a bioterium. Therefore, it is extremely important for the implantation of parasitic control of rabbits kept in bioterium for scientific purposes, the monitoring of possible infections by means of periodic coproparasitological exams.

Molecular characterization of Eimeria spp. and Blastocystis in rabbits in Shandong Province, China.

Eimeria spp. and Blastocystis are the common parasites that parasitize the intestinal tract of rabbits, which can seriously threaten the health of rabbits and lead to economic losses to the rabbit industry. However, information about the prevalence and transmission of these two parasites in rabbits is limited in China. The objective of this study was to survey the prevalence of Eimeria spp. and Blastocystis in rabbits in Shandong Province. A total of 616 rabbit fecal samples were collected from two cities (Rizhao and Weihai) in Shandong Province, eastern China, and Eimeria spp. and Blastocystis were identified by polymerase chain reaction based on species-specific markers. The prevalence of Eimeria spp. was 20% (123/616) and the Blastocystis prevalence was 0.97% (6/616). Five different Eimeria species (Eimeria intestinalis, E. perforans, E. magna, E. media, and E. irresidua) and the ST4 subtype of Blastocystis were identified in rabbits by sequence analysis. This is the first report of Blastocystis prevalence and subtype ST4 in rabbits in Shandong Province. The findings provide baseline data for the prevention and control of Eimeria spp. and Blastocystis in rabbits in Shandong Province, China.

BLOOD PARASITES AFFECTS LOCAL RABBITS IN IRAQ, A REVIEW

Rabbits are animals affected by many different species of parasites, infection Lead to lower body weight gain compared with non-infected rabbits , while sever infection Lead to death , although rabbits are less likely to develop epidemic diseases, but they are exposed to diseases of care and malnutrition, as well as parasitic diseases .Turning to previous studies that dealt with the spread of blood parasites in rabbits is a protozoan parasite such as (scab body, Babesia sp., Theileria sp., Anaplasma sp., Trypanosom sp. ,Plasmodium sp.). The current study aimed to defiend of blood parasite in rabbit in Iraq . Despite, the few of research on this subject for this study of blood parasites that Infection of rabbits and suggestion development of a database of studies of blood parasites affecting rabbits in Iraq.

The effect of self-licking behavior on pharmacokinetics of eprinomectin and clinical efficacy against Psoroptes cuniculi in topically administered rabbits

Ear mange mite Psoroptes cuniculi, one of the predominant parasites in rabbits, can cause considerable weight loss, low favorable fee conversion rates, and meningitis. The present experiment was to investigate the difference of plasma disposition and the variation of clinical efficacy under the effect of animal self-licking behavior in topically administered rabbits. Ten rabbits for pharmacokinetic study in two groups (the self-licking and the nonlicking)were topically administered with 1 mg kg(-1) of eprinomectin. In the self-licking group, rabbits were allowed to self-lick freely, while, to prevent self-licking, each animal in the non-licking group was fitted with a pet collar. Compared to the non-licking group, self-licking behavior contributed to an extremely significant shorter half-life of absorption (14.85+/-2.79 h in licking group vs.29.44+/-7.81 h in non-licking group, p<0.01) and an extremely significant higher C(max) value for eprinomectin (21.95+/-5.36 h in licking group vs. 6.98+/-0.72 ng ml(-1) in non-licking group, p<0.01) in plasma disposition. An extremely significantly shorter mean residence time (50.72+/-3.45 h) in self-licking group was also determined compared with the value obtained in non-licking group (106.66+/-7.39 h; p<0.01). Clinical efficacy study of eprinomectin was examined in rabbits naturally infested with P. cuniculi which were randomly allocated in three groups: the self-licking, the non-licking, and control groups. All rabbits in the self-licking and the non-licking groups were treated with topical eprinomectin at a single dose of 2 mg kg(-1) (day 0). Topical eprinomection led to a complete parasitological recovery in both treated groups on day 14 and remained free of live mites and clinical lesions from day 21 to the end of the study period (day 35).

REDESCRIPTION, SYNONYMY, AND NEW RECORDS OF VEXILLATA NOVIBERIAE (DIKMANS, 1935) (NEMATODA: TRICHOSTRONGYLINA), A PARASITE OF RABBITS SYLVILAGUS SPP. (LEPORIDAE) IN THE UNITED STATES

Vexillata noviberiae (Dikmans, 1935) (Trichostrongylina: Heligmosomoidea), originally described as a parasite of Sylvilagus floridanus from Louisiana, is redescribed from material collected from Sylvilagus palustris in Florida and from S. floridanus in Kansas. New morphometric and morphological data are provided. Stunkardionema halla Arnold, 1941, described from S. floridanus from Kansas and New York, is proposed as a junior synonym of V. noviberiae. These findings confirm the occurrence of V. noviberiae as a parasite of rabbits and its wide distribution range in North America.

L’insémination traumatique chez les oxyures de dermpotères et de léporidés

A morphological study of traumatic insemination in the genera Auchenacantha, a parasite of Dermoptera, and Passalurus, a parasite of Rabbits, revealed that the same phenomenon appeared twice in distinct lineages. In the Auchenacantha, adult females are inseminated in the vagina vera modified into a spermatic pouch. In the Passalurus insemination occurs in the ventral hypodermal field. Adult males probably mate with the female larval, stage four.

Helminth Parasites of Rabbits of the Genus Sylvilagus

Helminth Parasites of Rabbits of the Genus Sylvilagus

On Cittotaenia denticulata (Rudolphi 1804), with Notes as to the Occurrence of other Helminthic Parasites of Rabbits found in the Aberystwyth Area

The examination of the rabbits of the Aberystwyth area has shown heavy infection with adult cestodes. Of 516 small intestines of rabbits examined 358, or 66 per cent., have harboured adult cestodes. Two species occur—Cittotaenia pectinata (Goeze 1782) and Cittotaenia denticulata (Rudolphi 1804). Neither appear to have been recorded for the British Isles before. Theobald (1910) refers to reports of the prevalence of tapeworms in rabbits from near Winchester and from Devonshire. The known distribution of C. denticulata is Germany and France, and of C. pectinata, Germany and France and a variety, var. americana, in North America. C. pectinata is found in that part of the small intestine nearest the stomach. C. denticulata occurs in the lower part of the small intestine. On no occasion have the two species been found in one rabbit.
