Urban parks and cemeteries constitute hot spots of bird diversity in urban areas. However, the seasonal dynamics of their bird communities have been scarcely explored at large scales. This study aims to analyze the drivers of urban bird assemblage seasonality in urban parks and cemeteries comparing assemblages during breeding and non-breeding seasons in the Neotropical Region.

Dogs act as peridomestic reservoir hosts for the protozoan parasite Leishmania infantum, a causative agent for human leishmaniosis, endemic throughout the Mediterranean basin. To assure consistent and accurate surveillance of canine infection and prevent transmission to people, consistent diagnosis of canine L.

- This study establishes reference intervals (RI) for total antioxidant status (TAS) in dogs, addressing gaps in existing data and factors that affect TAS measurement.
- The research involved blood samples from 190 healthy dogs of various types (pet, police, shelter), determining TAS through a specific commercial test following established veterinary guidelines.
- Results showed that police dogs had higher TAS levels than pet dogs, and significant relationships were found between TAS and several biochemical markers, enhancing the understanding of TAS in clinical practice for canines.
Article Synopsis
- Giardia duodenalis and Cryptosporidium spp. are common parasites causing diarrhea in young dogs and cats, prompting a study that compares various diagnostic methods in 328 fecal samples from both species.
- The study found a higher prevalence of G. duodenalis in dogs (30.2%) than in cats (11.6%), while Cryptosporidium spp. was found in 4% of the total samples, with similar rates in both species.
- The research indicates that direct immunofluorescence assay (DFA) is the most sensitive method for detecting G. duodenalis, and combining DFA with PCR is best for Cryptosporidium detection, with factors like sex and breeding history influencing infection rates
Article Synopsis
- The study investigates the presence and prevalence of canine vector-borne diseases (CVBD) on Boa Vista Island in Cape Verde, focusing on pathogens like Ehrlichia canis, Leishmania infantum, and others in 150 dogs, including strays and pets.
- A high seroprevalence of Ehrlichia canis was found at 82%, with many infected dogs showing no clinical symptoms despite high antibody levels.
- Co-infections were common, with some dogs testing positive for multiple pathogens, highlighting the complex epidemiology of CVBD in tropical regions.
