Institute of Pest Management, Sokoine University of Agriculture (SUA), Morogoro 67101, Tanzania.
Article Synopsis
- The study examined the presence of specific antibodies in rodents and livestock (cattle and goats) in the Kilombero district of Tanzania, linking them to various agricultural activities.
- The research involved capturing 179 rodents and collecting samples from 200 livestock across different agricultural settings, utilizing a microscopic agglutination test for identification.
- Results showed a seroprevalence of 17.3% in rodents and 8.3% in livestock, with variations based on the type of settlement and higher antibody levels during the rainy season, indicating potential zoonotic transmission related to occupational exposure.

Leptospirosis is a worldwide zoonotic disease caused by pathogenic spp, often occurring in tropical and subtropical regions. Focusing on development of rapid diagnostic methods to facilitate early diagnosis and a universal vaccine are the main critical issues to overcome the burden of leptospirosis. Here, we have studied the immunogenic potential of prepared recombinant Loa22 protein (rLoa22) of local pathogenic species in mice and its ability to induce humoral and cellular immunity, being further evaluated by analyzing the immunoglobulin G (IgG) subclasses and cytokines produced through immunization.

Dispersal patterns of zoonotic pathogens can be strongly influenced by mobility and contact among hosts. Toxoplasma gondii infection has been documented in many avian species, however, there is little information regarding free-living seabird populations. Leptospira can infect domestic and wild animals, with birds being potential carriers of the bacteria.

Article Synopsis
- * A study conducted from 2007 to 2021 in Spain found that 28.3% of 258 tested NHPs had antibodies indicating exposure to Leptospira spp., with the highest seropositivity observed in Hominidae species and certain wildlife centers.
- * This research represents the largest survey of Leptospira spp. in European NHPs, identifying exposure in nine species for the first time and underscoring the importance of monitoring these animals in captivity for conservation and health reasons.

Leptospirosis is an anthropozoonosis of economic and public health importance, caused by bacteria of the genus Leptospira. Horses are deemed important in its transmission chain due to their proximity to humans, and because the species is often asymptomatic, making these animals potential silent reservoirs. In this context, the objectives of this study were to determine the prevalence of seropositive horses for Leptospira spp.
