Antimicrobial resistance characterization of and isolated from marine coastal recreational waters in the State of São Paulo, Brazil.

Coastal water quality is facing increasing threats due to human activities. Their contamination by sewage discharges poses significant risks to the environment and public health. We aimed to investigate the presence of antibiotic-resistant in beach waters.

Serotyping and Antimicrobial Susceptibility Profiling of Isolated from Diseased Swine in Brazil.

is one of the major pathogens in swine intensive production systems. To date, 15 serovars have been described, and the prevalence of these serotypes in different geographical regions has been identified by several methods. outbreaks could be controlled with vaccination if it were not for serovar diversity and limited cross-serovar protection; consequently, antibiotic therapy continues to be necessary for infection control.

Pandemic Clones of CTX-M-15 Producing ST15, ST147, and ST307 in Companion Parrots.

Psittacine birds are commonly kept as companion birds and the maintenance of these birds in captivity may represent a zoonotic risk and contribute to the propagation of multidrug-resistant and β-lactamase extended-spectrum (ESBLs)-producing pathogens. This study aimed to identify and characterize strains of the Klebsiella pneumoniae complex isolated from diseased psittacine birds, determining virulence and resistance profiles. K.

Causes of Sow Mortality and Risks to Post-Mortem Findings in a Brazilian Intensive Swine Production System.

The present study was conducted to investigate the risk factors for post-mortem findings and causes of sow mortality. A post-mortem examination and microbiological investigation were conducted on 123 sows from a breeding herd with 15,000 dams. The mortality of spontaneous death in sows occurred mostly in the peripartum period (53%; p < 0.

Vagococcus sp. a porcine pathogen: molecular and phenotypic characterization of strains isolated from diseased pigs in Brazil.

Introduction: Vagococcus spp. is known for its importance as a systemic and zoonotic bacterial pathogen even though it is not often reported in pigs. This is related to the pathogen misidentification due to the lack of usage of more discriminatory diagnostic techniques.

Genetic diversity of Streptococcus suis serotype 2 isolated from pigs in Brazil.

Streptococcus suis is an emerging zoonotic pathogen that causes septicemia, meningitis, arthritis, and pneumonia in swine and humans. The present study aimed to characterize the genetic diversity of S. suis serotype 2 isolated from pigs showing signs of illness in Brazil using pulsed-field gel electrophoresis (PFGE), single-enzyme amplified fragment length polymorphism (SE-AFLP), and profiling of virulence-associated markers.

Pheno- and genotypic characterization of Pasteurella multocida isolated from cats, dogs and rabbits from Brazil.

Pasteurella multocida is the causative agent of many diseases of economic importance in veterinary medicine and is characterized by high zoonotic potential. Pet animals can be infected and play a major role as carriers. This study aimed to characterize the genetic diversity of P.

Characterization of Yersinia enterocolitica biotype 1A strains isolated from swine slaughterhouses and markets.

Yersinia enterocolitica is an important foodborne pathogen that causes illness in humans and animals. Y. enterocolitica is also the most heterogeneous species of the genus and is divided into distinct serotypes and over six biotypes.

Colistin resistance in Escherichia coli and Salmonella enterica strains isolated from swine in Brazil.

Reports about acquired resistance to colistin in different bacteria species are increasing, including E. coli of animal origin, but reports of resistance in wild S. enterica of different serotypes from swine are not found in the literature.
