A total of 28 faecal samples of different zoo mammals and seven group faecal sample of birds were examined at the Rajkot Municipal Corporation Zoo, Rajkot. Out of this, 16 (57.14%) and seven (100%) were found positive for parasitic infection in mammals and birds respectively. Among the infected mammals 11 (68.75%), three (18.75%) and three (18.75%) were positive for nematode, cestode and intestinal protozoa, respectively. In birds, nematodes and protozoans were recorded.
Faecal samples from 140 adult goats were collected and positive samples were examined quantitatively; goats having at least 500 eggs/g of faeces were selected and randomly divided into four groups. Faecal egg count reduction test was used to detect the efficacy of albendazole (ALB), levamisole (LEV) and ivermectin (IVM) in goats naturally infected with gastrointestinal nematodes in a semi-organized farm located in semi-arid region of Gujarat, India. ALB, LEV and IVM reduced faecal egg counts on 14th day post-treatment varied from 53% to 76%, revealing presence of resistance of worms to all these drugs. Finding IVM resistance in gastrointestinal nematodes is found to be alarming. Pre-treatment faecal culture of all the groups collectively revealed Haemonchus spp. as the predominant parasite again post-treatment faecal cultures further emphasize the pre-dominance of H. contortus in ALB-and LEV-treated groups. However, faecal cultures from IVM-treated group revealed predominance of Trichostrongylus species which were scarce in pre-treatment group. Study further reveals that only ALB was found to be effective against Oesophagostomum spp., and most of the gastrointestinal nematodes were found to have some degree of resistance against rest of the other drugs used in goats.
A study was conducted to assess the prevalence of helmith parasites of domestic wild and zoo pigeons in Gujarat, India by faecal sampling and postmortem examination. Qualitative examination of 78 faecal samples revealed 71 (91%) with parasitic infections of nematodes (85%), cestodes (31%) and Eimeria sp (77%). There were 200-1600 nematode eggs per gram during the monsoon season, which was high compared to the 200-1000 eggs per gram in winter and summer. In post-mortems 85% had parasitic infections, of nematodes (75%), cestodes (69%) and Eimeria sp (58%). Two species of nematodes (Ascaridia columbae and Capillaria obsignata) and five species of three genera of cestodes (Raillietina echinobothridia, R. tetragona, R. cesticillus, Cotugnia digonophora and Hymenolepis sp) were identified. Despite their parasitic infections, not a single pigeon revealed any alarming clinical signs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
