This study aimed to characterize 300 spp. strains isolated from 123 ornamental fish of 32 different species presenting with septicemia, skin lesions, and/or eye lesions. Within the 300 strains, 53.
View Article and Find Full Text PDFBacterial diseases are common in ornamental fish, more frequently associated with ubiquitous bacteria from the aquarium environment. The disease can lead to fish mortality and cause high economic losses if not rapidly controlled. The aim of this study was to identify the main causative bacterial agents of infection in ornamental fish with different clinical signs.

Considering that Brazil is a major pork producer and exporter, proper monitoring of the pathogen and resistance rates are required. We present here the characterization of Brazilian strains isolated over a 15 year period by pulsed-field gel electrophoresis (PFGE) typing, capsular, virulence, and antimicrobial resistance profiling.
View Article and Find Full Text PDFUrinary tract infections (UTI) are considered one of the most important diseases of sows due to its close relationship with reproductive problems such as reduced litter size, increase in the rate of return to estrous, vulvar discharge, abortion, mastitis and anestrus. Actinobaculum suis is one of the main agents involved in porcine urinary tract infection and is responsible for the most severe and fatal cases in sows. In the present report, 23 A.

Sixty Salmonella isolates were tested for in vitro colistin resistance and mcr-1, mcr-2, mcr-3 and mcr-4 genes. Two isolates harbored the mcr-1 gene and whole-genome analysis determined the serovar to be Schwarzengrund, ST96, harboring the IncX4 plasmid.

Objective: The aim of this study was to investigate the virulence genes, assess the phylogenetic background, clonal diversity, and the pattern of resistance to antimicrobials in 186 isolates of UPEC isolated from sows in Brazil.
Materials And Methods: Urine samples from 300 sows of three herds with clinical signs from São Paulo State (Brazil) were screened for UTI; samples with suggestive results were submitted to bacterial isolation.
serovar Pomona is one of the most important serovars associated with worldwide porcine leptospirosis, and its infection is characterized by high antibody titers and the establishment of a renal carrier state. Here, we present the draft genome sequence of serovar Pomona strain GR5 isolated from apparently healthy gilt in Brazil.
