“…This may resemble the results obtained by Jittapalapong et al (2012) and Verma et al (2018). However, other studies were contrary to this result and recorded that female goats appear to be more susceptible than male goats to parasitic infections (Alexander and Stinson, 1988;Tariq et al 2008 andZvinorova et al 2016). It is supposed that fecal examination-based survey was considered a good diagnostic tool for the most epidemic parasites in the investigation areas (El-Shahawy 2016).…”

“…These results were in line with those reported by Sultan et al (2016) who found that the Strongyle group infection prevalence was 19.21%. However, Singh et al (2015) and Zvinorova et al (2016) recorded much high prevalence (69.27 and 31%, respectively). The low prevalence of Trichuris ovis (5.33%) observed in this study was consistent with those obtained by Nwigwe et al (2013) and Singh et al (2015) as 2.43% and 3.85 %, successively.…”

Background: Gastrointestinal parasitic diseases remain an obstacle in goat industry in Egypt and worldwide. This study was conducted for assessing the prevalence of the gastrointestinal parasitic infections among goats in Giza Governorate, Egypt. To fulfill this study, examination of 225 fecal samples of live animals kept by small holders was done, as well as postmortem investigation of 135 random slaughtered goats' gastrointestinal tracts was achieved during the period from March to May 2018. Results: The examination of fecal samples revealed that overall prevalence of gastrointestinal parasitic infections among goats was 89.33%. The respective prevalence of kids, yearling, and adults were 89.16%, 98.44%, and 82.05%. The common parasitic infections prevalent were Coccidia spp. (76.89%), Entamoeba spp. (26.22%), Moniezia spp. (18.22%), Strongyle group (12.88%), Trichuris ovis (5.33%), Strongyloides papillosus (3.55%), Balantidium coli (2.66%), and Fasciola spp. (0.89%), successively. Mixed infection was recorded as 61.77% in the examined goats. The present study showed that the prevalence of infection by Coccidia spp., Moniezia spp., and Strongyle group was the highest in the yearling age group. In contrary, the infection prevalence of Entamoeba spp. was significantly high in the adult age group. No significant difference was found relying on the sex of the goats. The post-slaughtering finding showed that Haemonchus contortus was the most prevalent nematode followed by Trichuris ovis and Trichostrongylus axei. Remarkable infection percentage of Taenia hydatigena metacestode (Cysticercus tenuicolli) is recorded in the omentum of the intestine (31.85%). Conclusions: The present study provides basic data about the most prevalent GIP diseases among goats in Giza Governorate, Egypt, which required for evaluation of the followed management and control measures. This work elicited the risk of transmission of some zoonotic diseases via goats. Fecal examination and postmortem finding-based surveys remain of choice particularly in the deprived investigating areas.

“…Knowledge of biological specifics, especially those of human parasites, factors into the regulation of their numbers, more so in the ecosystems experiencing anthropogenic pressure. Also in several cases, such data is taken into account in species or genus identification (Liang et al, 2007;Wong & Candolin, 2015;Zvinorova et al, 2016). According to scientific reports, trichurosis is very common in wild and domestic ruminants.…”

Biological specifics of Trichuris оvis Abildgaard, 1795 and T. globulosa Linstow, 1901 parasitizing domestic sheep were analyzed enhancing the species identification of these nematode species. The embryonic development of nematodes was timed, survival of embryonic stages was determined taking into account their morphological and metric specifics in laboratory culture. Trichuris eggs were isolated from gonads of adult female nematodes collected from caeca of dissected sheep. Then the eggs were cultured at optimal temperature to the formation of eggs with mobile larvae. Six morphologically distinct stages of embryogenesis were established in T. оvis and T. globulosa nematodes. The protoplast stage lasted from the 1st to the 12th day in T. оvis and to the 18th day in T. globulosa. Blastomeric formation occurred from the 3rd to the 18th day in T. оvis and from the 3rd to the 21st day in T. globulosa. Bean-shaped embryos formed from the 6th to the 21st day in T. оvis, and from the 9th to the 30th day in T. globulosa. Tadpole-like embryos developed from the 12th to the 24th day in T. оvis and from the 18th to the 33rd day in T. globulosa. Larvae formed in eggs of T. оvis from the 18th to the 27th day, and in eggs of T. globulosa from the 21st to the 36th day. Mobile larvae formed from the 21st to the 30th day in T. оvis, and from the 30th to the 39th day in T. globulosa. At 27 °С, mature eggs with mobile larvae developed in 30 days in T. оvis and in 39 in T. globulosa. The egg survival in laboratory culture was 84.3 ± 4.2 % and 76.3 ± 1.5%, respectively. Developmental changes of metric parameters in Trichuris nematode eggs (length and width of eggs, plug length, eggshell thickness) were species-specific.

Prevalence and risk factors of gastrointestinal parasitic infections in goats in low-input low-output farming systems in Zimbabwe

Abstract: HighlightsHigh prevalence for Haemonchus and Eimeria spp.Site, season, sex and age significantly influenced gastrointestinal infections.Highest level of infections in the wet season, in males and in young animals.Parasite species composition and risk factors also varied by area.
