Emerald tree boas (Corallus batesii) are boids that in situ occurs in forested habitats in the Amazon Basin. The mycobacterial species can infect reptiles but the species Mycolicibacterium fortuitum was identified only in feces samples of ex situ Python regius and was isolated from granulomatous lesions of an ex situ Iguana iguana when was still part of the genus Mycobacterium. This article aims to report a mycobacteria infection case in a female Corallus batesii kept under human care.

- Neotropical primates, like brown howler monkeys, usually don't show signs of active tuberculosis (TB).
- An injured brown howler monkey was discovered in an urban area, and medical examinations showed inflammation in its lungs, lymph nodes, and liver.
- Testing confirmed the monkey was infected with Mycobacterium tuberculosis, emphasizing the need for TB monitoring in nonhuman primates.
Molecular detection of Sarcocystis sp. in a kept under human care black capuchin monkey (Sapajus nigritus., Goldfuss 1809) with necrotizing encephalitis.

A senile male black capuchin monkey (Sapajus nigritus) kept under human care in a Zoo was found dead after 2 weeks presenting signals of weight loss and hyporexia. Histopathological revealed a necrotizing encephalitis. Although it was not observed microscopically, Sarcocystis sp infection was detected in brain tissue from molecular assays.

Herein, we compared the detection and phylogenetic analysis of YF virus in two neotropical primates (NTP), a Callithrix detected in the previous epidemic period (2016-2020), and a Callicebus nigrifons, showing a new introduction of YF in 2023.

- * Out of 242 examined primates, 25.6% tested positive for herpesvirus, with varying prevalence among different species and a significant correlation with adult age and human care.
- * The results emphasize the need for ongoing monitoring of herpesvirus infections in these primate populations to prevent future outbreaks and protect both wildlife and human health.

Article Synopsis
- The case describes a hoary fox pup in Brazil, co-infected with canine distemper virus (CDV) and canine adenovirus type 1 (CAdV-1), which showed severe health issues leading to euthanasia.
- Pathological findings included mild hepatitis, bronchopneumonia, and corneal problems, with CDV and CAdV-1 antigens identified in various organs through immunohistochemistry.
- The study highlights the importance of monitoring wildlife diseases to recognize potential conservation threats and the need for mitigation measures.
Mucormycosis is rarely described in Platyrrhines. Herein, we describe the pathologic and molecular features of a gastric and hepatic infection by Mucor indicus in a marmoset (Callithrix sp.).

- Brazilian porcupine poxvirus (BPoPV) was identified in a free-ranging adult male hairy dwarf porcupine exhibiting severe skin lesions and lethargy in Brazil.
- Diagnosis was confirmed through various methodologies, including histopathology and electron microscopy, which revealed characteristic viral inclusion bodies and large brick-shaped virions.
- Following a comprehensive treatment plan that involved antibiotics and supportive therapies, the porcupine's skin lesions regressed, and post-treatment evaluations showed no remaining viral presence or significant pathology.
Toxoplasmosis is a zoonotic disease caused by the ubiquitous coccidia Toxoplasma gondii. Rodents play an important role in maintaining its life cycle, as they are one of the main diet sources for felids (wild and domestic), the unique definitive hosts. However, reports of toxoplasmosis in porcupines (Order Rodentia) are uncommon, with gaps concerning its pathophysiology.
