Digestive disorders in cattle are associated with the breeding system and feed provided to the animals. Abomasal compaction is primarily related to the ingestion of forage with elevated levels of lignin, low quality, and difficult digestibility. In addition, the excess of fibrous food in the diet can lea...

This study was developed to evaluate the clinical, hematological, and performance parameters of calves affected by diarrhea caused by the bacterial enteric pathogen Escherichia coli, treated with three different protocols containing sulfonamides. Fourteen Holstein calves we...
Salmonellosis is a foodborne disease (FBD) that affects public health and can cause death in people. Many outbreaks of Salmonellosis have been reported due to the contamination of raw milk and dairy products with the pathogen. To determine the prevalence of Salmonella spp. in milk samples from four dairy...
Bovine mastitis is the most important disease of dairy herds worldwide. Its main etiologic agents are bacteria, including Streptococcus agalactiae. The importance of this agent in bovine mastitis is because it is highly contagious and has a high impact on the occurrence of clinical mastitis cases and in ...
Mastitis causes significant economic losses to the dairy cattle industry. The present study aimed to evaluate the antibacterial properties of 39 heterocyclic derivatives (1,3-thiazoles and 4-thiazolidinones) against clinical mastitis isolates from dairy cows. Milk samples were collected from cows with cl...
The present study was aimed at subtyping of Stx1 and Stx2 genes and characterization of antimicrobial resistance in 106 Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle and sheep feces. PCR was used to determine the subtypes, and the disk-diffusion method was used to evaluate th...
The epidemiological characteristics of bovine leptospirosis in animals and herds in Mato Grosso do Sul were investigated to determine parameters such as disease frequency and the serovars reactant in beef cattle herds. A total of 4,629 beef cattle herds were examined against 33 Leptospira spp. serovars. ...
La salmonelosis es una de las enfermedades bacterianas que afectan el tracto digestivo de los terneros y provocan en ellos diarrea. Con el objetivo de estudiar la prevalencia de los distintos serovares de Salmonella en terneros de crianza artificial y determinar la asociación con signos diarreicos, se r...

Bovine mastitis has a negative impact on milk production and can pose risks to public health. The present study aimed to evaluate the quality of bovine milk from small farms in the Botucatu/SP region. Somatic cell counts (SCC), identification of pathogens involved in mastitis, and sensitivity antimicrobi...
Abstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization of this bacterium. The objective of this work was to analyze the phylogeography of A. marginale based on the msp4 gene in beef cattle from the Brazil...
