The prevalence of Salmonella and thermophilic Campylobacter species in animals kept at the Emperor Valley Zoo, Trinidad, was determined. Of the 433 animals from a total of 30 species sampled, 28 (6.5%) and 11 (2.5%) were positive for Salmonella and Campylobacter, respectively. The difference was statistically significant (P < or = 0.001: chi2). Overall, 12 stereotypes of Salmonella were isolated, with S. miami accounting for eight (25.8%) of 31 isolates. All Campylobacter isolates were C. jejuni, with nine (81.8%) of 11 isolates originating from birds. Reptiles had a high prevalence of Salmonella infection with a high probability for salmonellosis, but the risk of campylobacteriosis appears to be very low.

Objective: Bacterial gastroenteritis is a significant public health concern, capable of causing severe infections. Among the various pathogens involved, those belonging to the Enterobacteriaceae family are the most frequently isolated and associated with gastrointestinal disorders. This study aimed to investigate the prevalence of common diarrheagenic Enterobacteriaceae in Iran over the past two decades, from 2000 to 2023.

Globally, an estimated 1 billion people reside in endemic areas, and over 12 million individuals are infected with leishmaniasis. Despite its prevalence, leishmaniasis continues to be a neglected disease, mainly affecting underdeveloped countries. In Brazil, the available treatments are pentavalent antimonials and Amphotericin B, which are outdated, toxic, require prolonged parenteral administration and have limited efficacy.

Salmonellosis is the second most important zoonosis in Europe, with consumption of contaminated broiler meat and its derivative products as an important source of infection. One of the many measures to prevent Salmonella contamination of poultry meat at the slaughterhouses is logistic slaughter, this means that per day the contaminated flocks are slaughtered after the Salmonella free flocks. However, this principle relies on a monitoring system at farm level that is prone to false negatives.
