Diversity and prevalence of gastrointestinal parasites of Black Bengal goats in Natore, Bangladesh

Abstract

Objectives: The objective of this work was to estimate the diversity of gastrointestinal (GI) para¬site species, their prevalence, and risk factors in Black Bengal goats (BBGs) of Natore, Bangladesh. Materials and Methods: Fecal samples from randomly selected 260 BBGs were processed through Stoll’s ova counting method, floatation, and simple sedimentation method. Microscopy-based identification of parasitic eggs, cysts, or oocysts was made. A semi-structured question¬naire-based data on host and management practices were collected from the owner. Data analysis was done using Statistical Package for Social Sciences. Results: The overall prevalence of GI parasites in BBGs was 65.4%, with an individual prevalence of 8.5% for Fasciola gigantica, 21.5% for Paramphistomum spp., 20% for Haemonchus spp., 34.2% for Strongyloides spp., 8.5% for Trichuris spp., and 9.2% for Eimeria spp. No significant effect of host age, gender, body condition, animal rearing system, or housing floor type was observed on parasitism. Animals of young age, female, poorly body-conditioned, living in a free-range system, and housed on a muddy floor had a relatively higher susceptibility to infection. Deworming had a significant impact on reducing the frequency of caprine GI parasitism. Conclusions: Despite the significant effect of anthelmintic, the elevated prevalence of GI parasites in BBGs suggests a critical need for developing effective strategies to prevent caprine parasitoses.

Gastrointestinal parasites in free grazing goats from Ayacucho, Peru: prevalence and risk factors associated with infection in herds

“…For instance, goat farmers in Ocaña district use a health plan calendar in which they consider deworming their animals one to two times a year. In contrast, farmers in the districts of Colca, Pacaycasa, and Luricocha do not adopt any type of sanitary management, there is overcrowding of animals with reduced resting areas, no sanitary measures are applied and they were not aware of any proper deworming calendars (Chakrabortty et al, 2023). Moreover, these districts have mostly mixed herds (along with sheep) which creates conditions for greater exposure (Chartier & Paraud, 2012).…”

“…The FEC in Colca district turned out to be higher (3334.87 ± 3631.82) than those recorded in the districts of Ocaña, Luricocha, and Pacaycasa. This high value observed in Colca could be a consequence of the level of susceptibility of the herds (Cabaret et al, 1998), speci c environmental and/or geographical conditions (Rabbi et al, 2013;Ratanapob et al, 2012), and the lack of anthelmintic usage (Chakrabortty et al, 2023). The FEC for Eimeria spp.…”

“…The grazing areas present suitable conditions for the development of gastrointestinal parasites. Hence, it is necessary to identify the epidemiological factors that affect the presence of gastrointestinal parasites to formulate effective prevention and control measures (Income et al, 2021; Rahman et al, 2017;Chakrabortty et al, 2023). However, the few epidemiological studies conducted on gastrointestinal parasitosis infection in goats in Ayacucho have been very limited.…”

Comparison of the first time detected Oesophagostomum asperum with Oesophagostomum columbianum in sheep and goats in Bangladesh based on the trinity: Morphology, morphometry and genetic diversity

“…Sample requirement of this study was determined using the formula generated by Thrusfield (1995) . Considering the prospective prevalence of 50 % (P = 0.50) ( Chakrabortty et al, 2023 ) and a precision of 5 % (d = 0.05), 384 samples were obtained from the study areas of Mymensingh ( Fig. 1 ) at 95 % (i.e.…”

“…globally including in Central Mexico (4.5 % in sheep), Ethiopia (58.7 % in sheep and 50.8 % in goats), India (82.9 % in goats and 55.4 % in sheep), Cameron (90 % in both species), China (82.2 % in sheep) and Myanmar (Acevedo-Rami rez et al, 2019; Choubisa and Jaroli, 2013 , Hou et al, 2022 , Negasi et al, 2012 , Ntonifor et al, 2013 , Win et al, 2020 ). In Bangladesh, the reported prevalence of GI nematode infection ranged from 63 to 89.8 % and 63–92 % in sheep and goats, respectively ( Chakrabortty et al, 2023 , Mazid et al, 2006 , Mohanta et al, 2007 ).…”
