Salmonella Dublin is a serovar that causes severe infections and cattle. Despite the importance of this agent, research on achieving its elimination from dairy farms limited, which complicates risk mitigation control efforts. This study thus aimed to assess prevalence S . farm with history outbreaks, understand dynamics infection, characterize antimicrobial resistance isolates, evaluate their genetic similarity. Multiparous cows in postpartum phase are nearly five times more likely shed sp....
ABSTRACT Skin loss can be caused by accident, burn, trauma, chronic wounds, and diseases, which is severely aggravated multidrug‐resistant bacterial infections. Soft hybrids based on biopolymers combined with silver nanoparticles (AgNPs) have potential applications as wound dressing supports skin tissue repair. Thus, our study focused the design, green synthesis, comprehensive characterization of carboxymethyl cellulose (CMC–AgNP) nanocomposites for producing hydrogel membranes, tunable...
The present study aimed to explore the motivations of Brazilian dog owners and their knowledge about risks related raw meat-based diets (RMBD) as well evaluate important enteropathogens such Salmonella spp., C. perfringens, difficile, in feces dogs fed different diets. majority pet (69.3%) reported have chosen this diet for dogs, considering it be more "natural". A large number declared that RMBD do not pose health animals (87.9%) or humans (98.8%), even though almost one third respondents...
Considering the increasing popularity of reptiles as pets and their possible role reservoirs pathogenic microorganisms, aim this study was to isolate Escherichia coli, Salmonella spp., Clostridium perfringens, C. difficile strains from in Brazil characterize isolated strains. The characterization based on phylogenetic typing E. identification virulence genes difficile, serotyping ribotyping MLST antimicrobial susceptibility test Cloacal swabs were collected 76 reptiles, which 15 lizards, 16...
The practice of feeding dogs raw meat-based diets (RMBDs) is growing in several countries, and the risks associated with ingestion pathogenic antimicrobial-resistant Escherichia coli fed these are largely unknown. We characterized E. strains isolated from either an RMBD or a conventional dry feed, according to phylogroup, virulence genes, antimicrobial susceptibility profiles bacteria. Two hundred sixteen were isolated. Dogs RMBDs shed phylogroup E more frequently positive for heat-stable...
ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by multidrug resistant Salmonella Typhimurium in hospitalized calves at veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) showed lethargy, hyperthermia profuse diarrhea despite treatment, 26 (41.2%) animals died. Five were necropsied stool samples of six collected. isolated strains subjected antimicrobial susceptibility test disc-difusion method fingerprinted ERIC-PCR. Macroscopic...
Biochemical, serological, and molecular methods have been developed for the laboratory diagnosis of diseases caused by C. pseudotuberculosis (CP), but identification pathogen biovars differentiation may be time-consuming, expensive, confusing compared with other bacteria. This study aimed to evaluate MALDI Biotyper Overall Genome Relatedness Index (OGRI) analysis optimize pseudotuberculosis. Out 230 strains isolated from several hosts countries, 202 (87.8%) were precisely classified using...
Abstract Streptococcus equi subsp. zooepidemicus is an opportunistic pathogen associated with disease in a range of domestic and wild animals. Despite its importance, very limited data available on survival persistence the environment. The goal this study was to evaluate S. under ideal culture conditions farm-like setting, various surface types. Rubber, plastic, wood, concrete samples were sterilized inoculated 10 9 CFU/mL or without feces, cultured (37 °C, 5% CO 2 ) settings (20 o C air)...
ABSTRACT: Clostridioides (Clostridium) difficile is the main causative agent of antimicrobial-related diarrhea in humans and a major pathogen-associated enteric disorder foals adult horses. Moreover, studies have suggested that animals are possible reservoir toxigenic C. strains for humans. Despite this known importance, epidemiology infection (CDI) equine still largely unknown. Therefore, study described six cases CDI occurring Minas Gerais, Brazil, including characterization isolates. All...
ABSTRACT: The present study aimed to describe and characterize, for the first time, two outbreaks of salmonellosis caused by Salmonella Ndolo in foals calves Brazil compare isolated strains with S. previously identified asymptomatic reptiles. affected presented fever, lethargy, profuse diarrhea. Isolated were subjected antimicrobial susceptibility testing, characterized according virulence genes, fingerprinted ERIC-PCR. was fecal samples from four calves. One isolate a calf resistant...
The aim of this study was to identify possible effects different vaccination strategies (concomitantly or not) against brucellosis and clostridia on intake, performance, feeding behavior, blood parameters, immune responses dairy heifers calves. Fifty calves were enrolled [38 Gyr (Zebu, Bos taurus indicus) 12 5/8 Holstein × Gyr]. At 120 d age, animals randomly distributed among 3 groups: B (n = 18), vaccinated brucellosis; C 14), CB concomitantly for both. Rectal thermographic temperatures...
ABSTRACT: A 10-day old foal presented with a history of acute recumbency and generalized weakness, that progressed to seizure episodes death. Post mortem examination revealed necrotizing purulent omphalophlebitis fibrinopurulent meningoencephalomyelitis. Salmonella Typhimurium was isolated from the central nervous system determined be cause Due lack evidence gastrointestinal disease, umbilical cord considered most likely portal entry bacteria. The S. resistant ampicillin cephalotin,...
ABSTRACT: The aims of the present study were (i) to genotype Corynebacterium pseudotuberculosis, C. silvaticum, and auriscanis strains using enterobacterial repetitive intergenic consensus (ERIC-PCR), (ii) analyze epidemiological relationships among isolates according biovar (Equi Ovis), species, host, geographical origin pseudotuberculosis strains. Sixty-eight nine one auriscanis, ATCC® 19410™ strain attenuated 1002 vaccinal fingerprinted by ERIC 1+2-PCR. Field isolated from various hosts...
ABSTRACT: Pigeons are known for their capacity to harbor and spread several zoonotic agents. Studies have suggested that pigeons also relevant disseminators of multidrug-resistant strains. In this study, surrounding a veterinary hospital were sampled tested the presence pathogenic Escherichia coli, Salmonella spp., Staphylococcus Clostridioides (Clostridium) difficile. E. coli isolates from 19 (40.4%) positive heat-stable enterotoxin 1 (EAST1)-encoding gene. The intimin-encoding gene (eae)...
Os animais domésticos são colonizados por uma extensa diversidade de bactérias comensais e patogênicas. Particularmente, os estimação têm sido apontados como reservatórios algumas específicas, Salmonella spp. Clostridioides (Clostridium) difficile. Esses também podem estar infectados helmintos potencialmente zoonóticos. No entanto, pouco se sabe sobre fatores risco frequência desses patógenos em cães no Brasil. O objetivo neste estudo foi avaliar a presença spp., C. difficile com potencial...
