Article Synopsis
- Non-human primates, particularly southern brown howler monkeys in Brazil and Argentina, share a close relationship with humans, making them important for studying infectious agents.
- A study collected and analyzed stool samples from free-living and captive howler monkeys, revealing intestinal parasites like Giardia duodenalis and Cryptosporidium spp. for the first time in this species in the wild.
- The presence of these parasites, especially one that can be transmitted to humans, highlights the impact of human activities and habitat fragmentation on wildlife health and underscores the need for eco-health measures.
Despite knowledge on the therapeutic properties of fungal bio-compounds, few studies have been reported on their anti-parasitic activities. The anti-parasitic activity (APA) of mycelial extracts from seven medicinal agaricomycetous mushrooms (Polyporus lipsiensis, Ganoderma applanatum, Pleurotus ostreatus, P. flabellatus, Oudemansiella canarii, Lentinula edodes, and Pycnoporus sanguineus) against Giardia duodenalis, and identification of chemical compounds produced by mycelium P.

The present paper identified the compounds produced by mycelium grown in submerged fermentation and investigated the antigiardial activity potential of extracts . mycelium crude extract () was obtained by the maceration process and after purification in column, thirty compounds were identified by gas chromatography - mass spectrometry (GC-MS) in hexane sub-fraction ().

The present study aimed to identify liposoluble molecules produced by Ganoderma lipsiense grown in red rice medium using solid-state fermentation (SSF) techniques, and to investigate the antigiardial and antibacterial activities potential of extracts in vitro. Eighteen fatty acids and derivatives were identified by gas chromatograph-mass spectrometry (GC-MS) analysis in G.

Methods: One hundred and forty-three students' blood samples and their vaccination schedules were analyzed.
Introduction: The objective was to identify comorbidities related to HIV-positive patients in Blumenau, State of Santa Catarina.
Methods: A retrospective, descriptive observational design study which analyzed data from 424 patients assisted by the sexually transmitted disease/acquired immunodeficiency syndrome (STD/AIDS) Specialized Care Service (SCS).
Results: Of 424 medical records analyzed, 388 patients presented CD4+/CD8+ ratios lower than 1.
