This pilot study describes the prevalence of Leptospira infection and exposure in livestock species, cattle, pig, sheep, and goats in Saint Kitts in the Caribbean region. Serum and kidney samples were collected from cattle, pigs, sheep, and goats at a local abattoir between September 2016 and March 2017. Cattle had the highest seroprevalence (79.8%) followed by pigs (64.8%), sheep (39.4%), and goats (24.8%). Highest seroprevalence was observed to serovars, Mankarso in cattle, Bratislava in pigs, Hardjo in sheep, and goats. Leptospira DNA was amplified from kidney samples of 18/99 cattle (18.2%), 11/106 pigs (10.4%), 4/106 sheep (3.8%), and 2/105 goats (1.9%). Our findings warrant further studies to assess leptospirosis associated economic burden to subsistence farmers and public health impact.

This observational study highlights the apparent lower severity of footrot in goats compared with sheep, the risk of false negative results from elastase tests, the need to clean contractors' equipment between properties and indicates the potential use of kidding (or lambing) time and individual mob biosecurity in managing footrot.

Bluetongue (BT) is a vector-borne viral disease of multiple domestic and wild ruminants across the globe. The VP7 protein of bluetongue virus (BTV) is the major immune-dominant structural protein that is conserved across the BTV serotypes and therefore, targeted for the development of immuno-diagnostics for BT. In this study, full-length recombinant VP7 protein (rVP7) of BTV-1 was expressed in Trochoplusia ni derived insect cells (Tn5) using codon-optimized synthetic gene construct through baculovirus expression system.

In integrated crop-livestock systems, livestock graze on cover crops and deposit raw manure onto fields to improve soil health and fertility. However, enteric pathogens shed by grazing animals may be associated with foodborne pathogen contamination of produce influenced by fecal-soil microbial interactions. We analyzed 300 fecal samples (148 from sheep and 152 from goats) and 415 soil samples (272 from California and 143 from Minnesota) to investigate the effects of grazing and the presence of non-O157 Shiga toxin-producing Escherichia coli (STEC) or generic E.

Echinococcus granulosus is a zoonotic dog parasite, which causes cystic echinococcosis in humans and animals, adversely affecting health and food production. The resultant socio-economic impacts in lower-middle-income countries and the paucity of epidemiology data prompted the World Health Organization to classify cystic echinococcosis as a neglected tropical disease. Between November 2019 and December 2020, the prevalence of cystic echinococcosis was assessed from 3600 post-slaughter livestock (1142 sheep, 1258 goats and 1200 buffalo) from three districts, Narowal, Sheikhupura and Sialkot, in Northern Punjab, Pakistan.

Orf is a parapoxvirus endemically found in sheep and goats. Orf can be transmitted to humans in close contact with infected animals, causing a self-limited viral skin infection known as ecythyma contagiosum. The diagnosis can be made clinically and treatment is usually conservative; however, unfamiliarity with orf may lead to an extended work-up.
