Prevalence and risk factors for gastrointestinal parasitism in traditionally maintained goat flocks of South Gujarat

Abstract

A total of 360 faecal samples of goat belonging to Ahir community were collected randomly from eight villages on monthly basis. On same day, collected samples were subjected to qualitative faecal examination and positive samples were categorized into mild, moderate and heavy infected groups. The risk factors considered for study were age, pregnancy, lactation, seasons, wet land grazing and hygiene in housing. Overall 41.11 % animals were found positive for helminth eggs and among them 24.17, 10.56 and 6.39 % of goats were mildly, moderately and heavily infected, respectively. The helminths recorded were strongyles (26.9 %), amphistomes (18.1 %), spp. (8.1 %) and spp. (3.9 %). Similarly, 72 (20 %) animals were found positive for presence of coccidia oocysts in which 13.06, 4.17 and 2.78 % were having mild, moderate and heavy infection. The Chi square test revealed that the housing quality, seasons and body condition scores (BCS) were having significant effects on helminths prevalence. The Chi square values indicated that age, hygiene of houses, seasons and BCS have significantly associated with prevalence of coccidiosis. The helminths prevalence was having significant positive correlation with lactation status and housing quality whereas it was significantly negatively correlated with prevalence of coccidia. Kendall's Correlation coefficients among various risk factors reveals that age and housing quality has significant negative correlations with coccidia infection. The gastro-intestinal (GI) parasites incidence was significantly high during the monsoon than the summer/winter season. The correlation of GI- parasitic prevalence with pregnancy status and age was not found.

Gastrointestinal Parasites in Sheep from the Brazilian Pampa Biome: Prevalence and Associated Factors

“…Parasitic diseases can affect any animal in the herd; however, they are more severe in young animals, especially lambs. In this study, sheep younger than 18 months tended to be more susceptible to strongyle infection compared to adults; although, these differences were not significant ( p > 0.05), similar to the studies of Dagnachew et al (2011) and Sorathiya et al (2017) . These authors related the lack of statistical findings to the lower number of young animals compared to adults.…”

“…Therefore, the development of ecological and integrated parasite management is needed to minimise the parasite population below the disease threshold level. For this, it is necessary to study all risk factors associated with parasite prevalence in a determinate geographic region ( Sorathiya et al, 2017 ). The amount of parasite eggs and oocysts shed in the hosts’ faeces is inversely proportional to the degree of resistance to parasitosis.…”

“…Visual observations were also made to confirm the questionnaire responses and assess farming practices. Risk factors were estimated based on previous studies in livestock ( Sorathiya et al, 2017 ; Squire et al, 2019 ).…”

“…In current work, all the fecal samples collected from different hosts were examined by the microscope observation and most of them showed positive infection, but the species of parasites were much less than the record in other documents (Boomker et al, 2000;Booyse and Dehority, 2012;Hyuga and Matsumoto, 2016;Sorathiya et al, 2017;Chartier and Paraud, 2012). The reason maybe contributed to the Zoo garden has a short history with only twelve years and located in the forestry different from other zoos.…”

Partial purification and characterization of glutathione S-transferase from the somatic tissue of Gastrothylax crumenifer (Trematoda: Digenea)

“…In general, the adult forms of amphistome parasites manifest diminished pathogenicity, but the immature rumen flukes during their course of migration lead to severe pathological disturbances including hemorrhagic inflammation in the wall of alimentary tract [ 2 ]. In India, several outbreaks of acute amphistomosis associated with high mortality among young sheep, goats, cattle, and buffaloes have been recorded [ 3 - 6 ]. In the absence of commercial vaccine, chemotherapy is the only way to deal with these rampant and neglected epidemic infections, but reports on emerging anthelmintic resistance have necessitated the quest to find new drug targets and promising vaccine candidates.…”
