The literature regarding causes of animal mortality varies greatly in how it evaluates and describes reasons for euthanasia, showing a clear need for tools to identify, standardize, and map diseases. This study describes the application of the Animal Mortality Information System Database (DATASIMA) to monitoring and georeferencing animal mortality. An observational study was conducted on the dogs and cats euthanized at the Municipal Center for Environmental and Zoonotic Surveillance in João Pessoa, Paraíba.

- TOR kinases are crucial for nutrient signaling and cell growth, organized into TORC1 and TORC2 complexes.
- In budding yeast, TORC2 is particularly important for regulating growth rate and cell size, but how it functions is not fully understood.
- Researchers discovered that the kinases Yck1 and Yck2 significantly impact the phosphorylation and localization of Mss4, a key player in TORC2 signaling, but their inhibition has minor effects on well-characterized pathways, indicating a potential role in less defined TORC2 functions.
A congenital neurologic disorder affected a herd of Tabapuã cattle. Of 98 newborn calves, 12 (12%) were affected; they were sired by 3 related bulls. This frequency suggested a genetic disorder caused by an autosomal recessive gene.

This study describes the epidemiological, clinical, and pathological aspects of an outbreak of ruminal acidosis and ruminitis caused by the ingestion of hedge lucerne (Desmanthus virgatus L.) in 70 cattle in the state of Paraiba, Northeastern Brazil. The herd had been transported from the state of Piauí to Paraiba.

- The breeding of wild birds as pets in Paraíba is influenced by cultural and socioeconomic factors, as well as the declining status of the species.
- Data was collected from local breeders about their practices and the commercialization aspects of bird breeding, focusing on three main species known for their singing and use in bird fighting.
- The study highlights the complexity of captive breeding in terms of management practices and behavioral factors, indicating a need for further research to assess the impact of these practices on bird genetics through artificial selection.
