“…The species of nematode which we found is also distributed in the territories of other countries (Pinto et al, 2004;Rinaldi et al, 2007;Frank et al, 2013). However, the extent of description of this topic in different sources is not the same.…”

Passaluriasis is a common infestation of lagomorphs, which clinically manifests in intense itching around the anus, various disorders of digestion and loss of weight. We performed a study of infested rabbits of the seryi veleten breed, which were kept in individual farms in Poltava Oblast (Ukraine). During the autopsy, in the cavity of the large intestine, there were found small, spindle-like helminths of white colour. Out of 10 rabbits, 846 nematodes were extracted (369 males and 477 females, identified as Passalurus ambiguus (Rudolphi, 1819) Dujardin, 1845. It was determined that the extensity of infestation in female rabbits reached 56.4%, male rabbits – 43.6%. The results of metric parameters of the nematodes are as follows: mean body length of males equaled 4.6 ± 0.4, females – 9.7 ± 1.21 mm, and maximum width – 257.4 ± 17.8 and 546.2 ± 37.1 µm respectively. A common feature of mature nematodes of this species is the presence of a rounded extension (bulbus) at the end of the esophagus. During chronic course of passaluriasis in rabbits, pathomorphological changes developed in the large intestine. The upper epithelium of the large intestine was damaged in some places, certain epithelian cells were found in the lumen of the intestine. The intestinal glands are widened, filled with slimy content of mostly dark blue-violet colour, especially in the upper sections of the glands. In the deep sections of the glands, slime was almost transparent. In deep sections of the glands the slime was almost transparent. In the epithelium cells of the glands, slimy granules were also of basophilic colour. The muscularis mucosae of the mucous membrane, especially between the intestinal glands was swollen, had practically no colour, the collagen fibers were stretched, thinned-out. Edemas were also recorded in the tela submucosa. In some preparations, the muscularis mucosae was notably infiltrated by lymphoid cells and histiocytes. On large extensions, we found some signs of hypersecretion of slime in goblet cells of the intestinal glands as accumulations of granules of slime in the cytoplasm, which had poorly developed colouration. On the side of the muscular and serous membranes, no pathological changes were found. The information presented here indicates the relevance of passaluriasis infestation as an etiological factor of occurrence of chronic catarrhal colitis with lymphohistiocytosis.

“…The nematode Paraspidodera uncinata commonly infects guinea-pigs and octodontid rodents in Brazil, where it has also been recorded in European rabbits (Pinto et al 2004). It is not known whether it causes disease in rabbits, or if it is present in guinea-pigs in Australia.…”

Abstract. European rabbits are exotic pests in Australia, New Zealand, parts of South America and Europe, and on many islands. Their abundance, and the damage they cause, might be reduced by the release of naturally occurring or genetically modified organisms (GMOs) that act as biological control agents (BCAs). Some promising pathogens and parasites of European rabbits and other lagomorphs are discussed, with special reference to those absent from Australia as an example of the range of necessary considerations in any given case. The possibility of introducing these already-known BCAs into areas where rabbits are pests warrants further investigation. The most cost-effective method for finding potentially useful but as-yet undiscovered BCAs would be to maintain a global watch on new diseases and pathologies in domestic rabbits. The absence of wild European rabbits from climatically suitable parts of North and South America and southern Africa may indicate the presence there of useful BCAs, although other explanations for their absence are possible. Until the non-target risks of deploying disseminating GMOs to control rabbits have been satisfactorily minimised, efforts to introduce BCAs into exotic rabbit populations should focus on naturally occurring organisms. The development of safe disseminating GMOs remains an important long-term goal, with the possible use of homing endonuclease genes warranting further investigation.

“…Rabbits are one of the most common laboratory animals, used around the world in Experiences to estimate various biological parameters, and this animal is either conventionally preserved in animal facilities for use in scientific research or is also obtainable in pet store s and in backyard settlements for commercial purposes (Pinto et al, 2004). Rabbits are susceptible to a number of parasites, among the parasitic diseases of rabbits, those which deserve special attention are coccidiosis, skin mange, ear mange or ear cancer and stomach-worm diseases.…”

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.
