Summary: A study in Japan found that walking along a riverbed and exposure to Leptospira interrogans serovar Australis were associated with an outbreak of canine leptospirosis. The lack of a canine vaccine for this specific serovar highlights the need for further research on developing vaccines to prevent local outbreaks. Leptospirosis is an important infectious disease of dogs and is also zoonotic.

Summary: In this study, an acute case of leptospirosis in a puppy housed at a municipal kennel was reported, and diagnostic investigations were conducted on all dogs in the kennel. Laboratory tests including microagglutination test, real-time PCR, and MLST were performed. The puppy tested positive for Leptospira interrogans Icterohaemorrhagiae, while no other dogs showed clinical signs of leptospirosis.

Summary: The study found that volunteers' personalities have a significant impact on their interactions with shelter dogs. Neurotic volunteers tended to use more body language and pulled the leash harder, extroverted volunteers praised dogs in a high-pitched voice and had stronger leash tension, while open volunteers were less likely to verbally communicate with dogs.

Summary: Shelter dogs have a lower infection rate of Leishmania infantum compared to domestic dogs due to the better veterinary care provided in shelters. Monitoring and preventing canine leishmaniosis is crucial in reducing the spread of this disease among animals and humans. This study highlights the importance of One Health approach in tackling zoonotic diseases.

Summary: The MAT is a robust and inexpensive method used for the serological diagnosis of leptospirosis, but its performance and interpretation vary geographically, making standardization difficult. This study evaluated the usefulness of the ranking technique for predicting the probable infecting serogroup identified by the MAT, and found that the technique successfully eliminated cross reactions with other serogroups.

Summary: Long-term shelter dogs are more likely to be older, male, large in size, neutered, and of a dangerous breed, with frequent behavioral problems related to aggression and high arousal. While their physical well-being is not impaired, they show signs of stress and difficulties relaxing in the shelter environment, potentially impacting adoption rates.

Summary: The provision of nesting materials to farrowing sows has been shown to reduce redirected nest-building behaviors, improve farrowing traits and maternal behavior, and decrease pre-weaning mortality. However, the effects of nesting material vary depending on the type and quantity of material provided and the farrowing system.

Summary: Clinical endometritis (CE) and subclinical endometritis (SE) are two uterine diseases that can affect milk production and fertility in dairy cows during the puerperium period. This study found that cows with CE and SE had lower conception rates and milk production, but no effect on milk production during 305 DIM. Furthermore, cows with CE and SE but negative bacteria isolation did not have impaired reproductive performance and milk production during the postpartum period.

Summary: Clinical endometritis in dairy cows has negative effects on fertility and milk production, and causes additional treatment costs. This study evaluated the antibacterial activity of cinnamon, oregano, and thyme essential oils, alone and in combination, against bovine uterine pathogens. Cinnamon essential oil showed the lowest Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values. The study suggests that cinnamon essential oil has promising antimicrobial activity and could be explored as an alternative treatment for clinical endometritis in dairy cows.

Summary: Glanders is a bacterial disease that affects mainly equids and is caused by Burkholderia mallei. While it has been eradicated in certain regions, it continues to occur sporadically in Asia, Africa, the Middle East, and South America. A study conducted in Brazil found a low prevalence of infected properties and seropositive animals, but highlighted the need for reassessment of disease control strategies. The study emphasized the importance of involving both public and private entities in combating the disease.

Summary: This study aimed to investigate the species and antimicrobial susceptibility of Staphylococci on bat skin. The results showed that 42.8% of bats in the Metropolitan Region of Sao Paulo, Brazil carried Staphylococcaceae, mainly young bats in the rural area during summer. The majority of the isolates exhibited antibiotic resistance, indicating the potential transmission of clinically relevant Staphylococcus aureus and antimicrobial-resistant bacteria by bats.

Summary: Vampire bat-transmitted rabies is causing the most deaths from rabies in Latin America, affecting both humans and livestock. To assess the risk of bat-to-animal transmission, a spatially explicit bat-rabies dynamic modeling framework was developed and calibrated using real roost and farm data in Sao Paulo. The model incorporates roost and farm characteristics and environmental data to evaluate rabies transmission. Interventions to reduce risk in roosts (such as bat culling or vaccination) and in farms (cattle vaccination) were evaluated, with control in roosts being more effective. The identification of high-risk areas can aid in implementing control interventions.

Summary: This study investigated the influence of urbanization on bat species richness, relative abundance, and pathogen occurrence. The results showed that higher levels of urbanization led to lower bat species richness and higher relative abundance of captured bats. Noise level, luminosity, and relative humidity were correlated with bat abundance. Additionally, the study found that bats play a significant role in the circulation of pathogens of medical and veterinary interest. These findings are important for promoting harmonious coexistence between humans, bats, and domestic animals in areas with varying levels of anthropization.
