Dry salted shrimp is a popular food in Acre cuisine, especially as a main ingredient in “tacacá” and “rabada no tucupi”. However, different intrinsic and extrinsic factors can result in accelerated deterioration and microbial proliferation, causing food poisoning to the consumer. The objective was to perform the counting and identification of molds and yeasts in dry salted shrimp in establishments that sell typical foods in the municipality of Rio Branco, state of Acre. Shrimp samples from six establishments were collected in sterile bottles, identified, refrigerated and transported to the Laboratory of Infectious Diseases of Animals at the Federal University of Acre, for the manual counting of colony-forming units and identification of fungal genera. As a result, the number of molds and yeasts in the dried salted shrimp samples varied between 1.0x102 and 1.02x106 CFU/g. Nine fungal genera were identified: Aspergillus, Penicillium, Cladosporium, Malassezia, Fusarium, Exophiala, Candida, Curvularia and Trichosporon. The most frequent were Aspergillus, Penicillium and Cladosporium, these being potential producers of mycotoxins. The presence of molds and yeasts in the samples of dried salted shrimp shows the need for greater hygienic-sanitary rigidity of this fish at different stages of manipulation and processing as preventative measures for public health.

Histoplasma capsulatum is a saprophytic dimorphic fungus that causes histoplasmosis, a systemic infectious disease of relevance to public health. Bats can be important agents in the epidemiological cycle of the disease since they act as reservoirs of microorganisms. The aim of this study was to detect Histoplasma capsulatum in the lung tissue of bats captured in urban forest fragments in the municipality of Rio Branco, Acre, in the Western Amazon. Twenty-two bat species were captured from five urban forest fragments. The samples taken were subjected to histopathological, mycological, and molecular analysis. Among the 96 animals analyzed, the fungus was detected in 32.29% (31/96). This was the first study to detect the pathogen in bats in the Western Amazon. It is also the first record of the fungus being detected in six bat species. The state of Acre is located in a region with a rich diversity of bats. Furthermore, this area is constantly suffering from climatic and environmental changes that can favor the emergence and re-emergence of diseases. Thus, active epidemiological research and surveillance of neglected fungal infections are essential, especially considering the concept of One Health.

Psittaciformes kept as pets can serve as reservoirs of various microorganisms, many of which have zoonotic potential, including Candida spp. In this study, the antifungal susceptibility profiles of 16 Candida spp. isolated from the oral and cloacal cavities of 20 pet parrots were evaluated. Samples from the animals' oral and cloacal cavities were obtained with swabs and stored in sterile tubes. For mycological isolation, samples were seeded on Mycosel agar medium at 30°C (86°F) for up to 5 days. The 16 isolates were seeded onto chromogenic medium to verify the species. For the antifungal susceptibility profiles, the samples were diluted in saline solution and plated on Sabouraud dextrose agar plates with antifungal discs. The species identified were Candida glabrata (5/16, 31.2%), Candida albicans (4/16, 25%), Candida tropicalis (4/16, 25%), and Candida krusei (3/16, 18.8%). Twelve isolates were tested against 4 azole antifungals (miconazole, fluconazole, clotrimazole and ketoconazole). Approximately 58% (7/12) of Candida spp. isolates showed intermediate susceptibility or resistance to the drugs used, with fluconazole being the least effective antifungal. These findings provide important information about the microbiota of wild birds raised as pets in Brazil and warn of the emergence of Candida non-albicans spp. resistant to azole antifungals widely used in human and veterinary medicine.

The order Chiroptera is highly diverse and is the second richest among mammals. Approximately 181 species are known in Brazil, with varied feeding habits that make them essential for ecological functions such as seed dispersal and plant regeneration. Despite the importance of their ecosystem services, the anatomical and histological aspects of the digestive system of these animals are still little explored. The aim of this study was to describe the anatomical and histomorphological aspects of the intestines of A. lituratus . Six individuals were captured in peri‐urban areas of Rio Branco, Acre. After euthanasia, the intestines were removed, fixed in 10% formaldehyde and processed for macroscopic and histological analysis using Haematoxylin–Eosin staining. Macroscopically, it was not possible to accurately distinguish the small and large intestine portions. Microscopically, all the typical intestinal layers were present, with cells, glands and structures compatible with a frugivorous diet. The findings contribute to the knowledge of the species' digestive morphology and provide subsidies for future investigations into physiological adaptations related to its diet and ecology.
