Although the Brazilian State of Espírito Santo is not considered endemic for Chagas' disease, the sylvatic triatomines occurring there frequently invade houses, increasing the chances of Trypanosoma cruzi transmission to man. The epidemiological pattern of the disease in Espírito Santo was evaluated by a serological survey of 5,243 schoolchildren ages 7 to 14 years, residents of 17 municipalities. Indirect immunofluorescence, indirect hemagglutination, and immunoenzymatic (ELISA) tests were positive in only one person, representing only 0.019% of the total. This result was similar to those found by other authors in previous studies. Based on the results of serological tests it is concluded that the epidemiological pattern of Chagas' disease in Espírito Santo remains stable, despite the intensive destruction of the Atlantic Forest that has occurred in recent decades.

The severity of COVID 19 symptoms has a direct correlation with lymphopenia, affecting natural killer (NK) cells. SARS-CoV-2 specific "memory" NK cells obtained from convalescent donors can be used as cell immunotherapy. In 2022 a phase I, dose-escalation, single center clinical trial was conducted to evaluate the safety and feasibility of the infusion of CD3/CD56 NK cells against moderate/severe cases of COVID-19 (NCT04578210).

A search for antifungal compounds from the mushroom using a bioassay-guided chromatographic fractionation approach led to the discovery of a novel polyketide harboring a rare 3,3a,9,9a-tetrahydro-1-furo[3,4-]chromen-1-one skeleton. The novel compound was named coprinolide. The inhibitory activity and fungicidal potential of coprinolide were evaluated against five economically important plant-pathogenic fungi.

Infectious viral pathogens significantly impact wild Leporidae populations, particularly , which was listed as 'Endangered' in 2019. Myxomatosis and rabbit haemorrhagic disease are major contributors to severe epizootics with limited long-lasting immunity. This study expanded beyond these well-documented viruses to include a broader spectrum of viruses in 36 wild rabbit carcasses () collected from the field in 2018, 2019, 2021 and 2024, and 32 wild rabbits hunted in 2017/2018.

Subclavian artery aneurysm is an extremely rare condition with potentially life-threatening complications, including rupture and embolization. This condition is generally the result of atherosclerosis, medial degeneration, trauma, or infection. We report the case of an 83-year-old man who developed hemoptysis due to the rupture of a saccular aneurysm at the origin of the left subclavian artery.
