ABSTRACT: In the last few decades, there has been a global increase in the adoption of reptiles as companion animals, mainly turtles and tortoises. Considering the popularity of reptiles as pets in Brazil, and a notable lack of data about potentially pathogenic staphylococci in these animals, this study isolated and evaluate the antimicrobial susceptibility of staphylococcal species from healthy tortoises (Chel...
ABSTRACT: In dogs, antimicrobial therapy for Clostridioides (Clostridium) difficile infection (CDI) is based solely on metronidazole, leaving limited treatment options in case of recurrent disease. Fecal microbiota transplantation (FMT) has been successfully used in humans with recurrent CDI, whereas the usefulness of this approach is largely unknown in dogs. In the present study, a dog with a chronic-recurring...
ABSTRACT: Clostridioides (Clostridium) difficile is the main causative agent of antimicrobial-related diarrhea in humans and a major pathogen-associated enteric disorder in foals and adult horses. Moreover, studies have suggested that animals are a possible reservoir of toxigenic C. difficile strains for humans. Despite this known importance, the epidemiology of C. difficile infection (CDI) in equine is still l...
ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were coll...
ABSTRACT: This study identified the virulence genes, pathovars, and phylogenetic groups of Escherichia coli strains obtained from the feces of dogs with and without diarrhea. Virulence genes and phylogenetic group identification were studied using polymerase chain reaction. Thirty-seven E. coli isolates were positive for at least one virulence factor gene. Twenty-one (57.8%) of the positive isolates were isolat...
ABSTRACT: Despite the known importance of Clostridium perfringens as an enteropathogen in small ruminants, little is known about the role of its additional virulence factors or the frequency of the various C. perfringens genotypes in healthy goats; this complicates the laboratory diagnosis of the infections caused by this microorganism. In light of this, the aim of the present study was to isolate and genotype ...
ABSTRACT: The aim of this study was to evaluate the presence of microorganisms in honey produced by the stingless bee (SB) jandaíra (Melipona subnitida) from the semiarid region of Brazil. Thirty-five samples were analyzed and all of them were positive for mesophilic bacteria, coliforms at 45°C, fungi, and yeast. Staphylococcus spp. were identified in 85.7%, while Bacillus spp. were detected in 34.3% of honey s...
ABSTRACT: The present study aimed to describe and characterize, for the first time, two outbreaks of salmonellosis caused by Salmonella Ndolo in foals and calves in Brazil and compare the isolated strains with S. Ndolo previously identified in asymptomatic reptiles. The affected calves and foals presented fever, lethargy, and profuse diarrhea. Isolated strains were subjected to antimicrobial susceptibility test...
ABSTRACT: The importance of Clostridium perfringens and C. difficile for most wild animal species remains unclear. This study aimed to isolate and genotype C. perfringens and C. difficile in stool samples from free-living and captive capuchin monkeys (Sapajus flavius and Sapajus libidinosus) in Brazil. Ten free-living S. flavius and 14 captive S. libidinosus were sampled for this study. To isolate C. difficile,...
ABSTRACT: A standardized immunochemistry method for the diagnosis of clostridial myonecrosis was applied to 38 formalized tissue samples from ruminants with clinical and post mortem history suggestive of blackleg or gas gangrene. The diagnosis of clostridial myonecrosis was confirmed in 37 out of 38 (97.4%) samples tested. Clostridium chauvoei and Clostridium perfringens type A were the most common agents found...
