“…It could be due to the grazing practices in the study areas, mixed grazing and housing gave equal chances of all genders to be infected with gut parasites. The poor health condition had a significant effect on the occurrence of GI parasitism in both sheep and goats as seen in the current investigation and other published reports (Islam et al 2017a;Rahman et al 2017;Dey et al 2020). The animals with 'poor' health condition have low immunity to resist diseases including parasitic infections which might a probable reason of higher frequency of such parasitic infections (Watson et al 1994).…”

“…A lower occurrence was reported by Rajarajan et al (2017) and Dagnachew et al (2011) who reported 46% in sheep and 39 -55% in goats of India and Ethiopia, respectively. The reason of differences in the frequency of GI parasitic infections could be due to sampling size, geographic locations, the climate of the study areas, breed of animals, anthelmintic treatment, flock size and management systems (Hassan et al 2011;Zvinorava et al 2016;Dappawar et al 2018;Dey et al 2020). This study further showed a lack of significant difference in the overall occurrence of GI parasitic infections between the study animals.…”

“…However, Islam et al (2017b) found a higher prevalence in young animals whereas, Rahman et al (2017) and Singh et al (2017) found a higher frequency in adults. Grazing, housing and managemental practices could be the reasons of such variation (Hassan et al 2011;Dey et al 2020).…”

“…This could be due to an increase in the level of hormones like progesterone and prolactin during pregnancy and lactation makes female animal more vulnerable to any infection (Lloyd 1983). Further, some studies also demonstrated that the sex of the animals does have any significant association in the occurrence of gut parasites (Islam and Taimur 2008;Rahman et al 2017;Dey et al 2020). It could be due to the grazing practices in the study areas, mixed grazing and housing gave equal chances of all genders to be infected with gut parasites.…”

“…There are many associated risk factors involve in the occurrence of GI parasitic infections are species, age and gender, body condition of the animals, flock size, housing and rearing system, body deworming status of the animal, distribution of parasite species, in an area, the topography of an area etc. (Tariq et al 2010;Alim et al 2012;Dey et al 2020).…”

Gastrointestinal (GI) parasitic infection is considered a common problem in sheep and goat production in Bangladesh. The current investigation was undertaken to determine the prevalence of GI parasitic infection and its associated risk factors (e.g., age, sex, body condition & deworming status etc.) in sheep and goats of the Sandwip Island, Chattogram, Bangladesh. A total of 330 faecal samples of which 220 sheep and 110 goats were taken using a random sampling method. All the samples were subjected to routine coproscopy (e.g., direct smear, flotation and sedimentation) to detect the eggs/oocysts of helminths and protozoan parasites. Results demonstrated that the overall prevalence of GI parasitic infections was 68.64% in sheep and 61.82% in goats. The frequency of nematodes and trematodes was higher in comparison to cestodes and protozoan infections in both sheep and goats of all the three study areas. Adult goats had demonstrated significantly higher GI parasitic infections in comparison to the young population. Female sheep were more prone to GI parasitic infections whereas the opposite trend was noticed for goats. The sheep and goats having the 'poor' body condition score/nutritional status were more susceptible to parasitic infections compared to moderate and good health conditions. Rarely or non-dewormed sheep and goats also harboured more GI parasites compared 'dewormed animals'. The current research is the first in terms of species identified in study areas, therefore, we recommended extensive studies including epidemiological and molecular approaches to identify GI parasitic diseases and their associated risk factors.

Rhesus macaques are considered an important reservoir of different gastrointestinal (GI) zoonotic parasites affecting livestock and humans. Loads of GI parasites in the free‐ranging rhesus macaques living in close proximity to communities in Bangladesh are still unknown. To estimate the prevalence and diversity of zoonotic GI parasites in rhesus macaques of Bangladesh, a total of 182 freshly voided fecal samples were collected from macaques living in rural (N = 67), peri‐urban (N = 57), urban (N = 28), and Safari park (N = 30) between October 2015 and December 2016. All samples were tested by direct smear, sedimentation, flotation, and the McMaster techniques. A total of fourteen different taxa of GI parasites were detected, revealing an overall prevalence of 54.4% (n = 99; 95% confidence interval [CI]: 46.9–61.8). The prevalence of GI parasites was found to be significantly correlated with the mean parasitic taxa per individual in a group (r = 0.90; p = 0.002). The multivariable logistic regression analysis showed that the overall prevalence of GI parasites in macaques was significantly higher in those inhabiting rural areas (62.69%; odds ratio [OR]: 7.22; p = 0.001) and in macaques with interactions with other animals (60.98%; OR: 5.49; p = 0.005). Our results also indicated that the prevalence of Strongyloides spp. and Balantidium coli infections varied significantly between land gradients. Our results also indicate that macaques frequently visit human settlements for food and are found interacting with domestic animals. In conclusion, the high prevalence of zoonotic GI parasite infection in rhesus macaques found in our study may pose a significant public health risk to communities, particularly in rural areas of Bangladesh. Health promotion to at‐risk communities focusing on limiting contact with rhesus macaques is necessary to mitigate potential zoonotic transmission.

Background Bacillus anthracis is a zoonotic bacterium that affects wide numbers of vertebrate animals and man and has life threating potential both in animal s as well as humans. Methods A cross sectional study was conducted to assess the knowledge about, attitudes towards, and practices addressing (KAPs) anthrax among community members in selected upazillas’ of Meherpur and Sirajgonj districts for the prevention and control of anthrax using a structured questionnaire. Results A total of 424 community members were considered in this study irrespective of their age and sex. Most of the respondents were female (57.54%) and about half were illiterate (47.40%). Most of the respondents (86.32%) were self‐employed with crop and livestock farming. Among the self‐employed farmers, cattle (63.73%) were the highest reared animals. Among the respondents, 37.26% had no knowledge about anthrax. On the other hand, among the existing knowledge level, 46.69% received information of anthrax from neighbour, 74.05% and 56.82% were concerned about the mode of transmission of anthrax from animal to human through eating, handling and soil. Respondents usually collected vaccine from quack (58.25%) and vaccination status was highest in Kamarkhand (52.03%) and lowest in Gangni upazilla (10.82%). Overall 62.74% community members considered that anthrax is a fatal disease for livestock and 82.54% people disposed carcass in buried method. Conclusion The study findings indicated that the community members had average knowledge on cause, symptoms, transmission and prevention of anthrax. The supplied vaccine was found negligible with the number of livestock in the studied upazilas. Veterinary and Medical health planners should design and implement interventions for awareness building on anthrax under One Health (OH) approach for educating the community people on anthrax control and prevention.
