Coccidioidomycosis is a systemic infection caused by Coccidioides spp. The disease is endemic in Brazil but its incidence is underreported as it is not a notifiable disease. This article presents the results of a serologic survey carried out with 229 volunteers in northeast Brazil by the immunodiffusion (ID) test with commercial Coccidioides spp. antigens. The commercial ID test detected 15 individuals without clinical diagnosis of the disease and two individuals in treatment for coccidioidomycosis. Regarding the epidemiological data, most of the positive individuals were male, between 18 and 65 years of age and were engaged in armadillo hunting. Three women who had never participated in armadillo hunts also displayed positive results for coccidioidal antibodies. Besides armadillo hunts, exposure to environmental dust in endemic areas may account for the serologic response detected in the study. The data from this study suggest the importance of performing epidemiological surveys for coccidioidomycosis in order to understand the prevalence of this disease in Brazil.

The Atlantic Forest broad-snouted caiman (Caiman latirostris) inhabits regions within one of the world's most ecologically diverse ecosystems, yet few studies have explored the relationship between body condition, blood biochemistry, and environmental factors in the wild. Our study investigated the effects of sex, ontogeny, habitat, and environmental variables on the body condition and blood biochemistry of free-ranging caimans from the state of Alagoas, Northeast Brazil. From 2020 to 2022, we captured 75 caimans across three sites in different seasons.

The development of COVID-19 vaccines has been an important step in the fight against the pandemic. However, it is still necessary to understand the influence of factors that can alter the immune response. In general, doses need to be updated frequently, and care must be taken to control the virus that is still circulating worldwide.

Arbovirus surveillance in marmosets (Callithrix spp.) that live close to humans helps identify viral circulation in the environment and contributes to public health. We investigated the exposure to arboviral infections in 47 captive and free-living Callithrix from urban and peri-urban areas in the semiarid region of northeastern Brazil (SNB) in 2018.

The genus Wittmackia has 44 species distributed in two centers of diversity: the Brazilian clade and the Caribbean clade. The Brazilian clade includes 29 species, with geographic distribution concentrated in the Northeast of Brazil. This study reports the morphology, ultrastructure, pollen viability and stigma receptivity by different microscopy techniques of 23 species of the genus Wittmackia endemic to Brazil and occurring in Atlantic Forest areas.
