Genomic Analysis of a Community-Acquired Methicillin-Resistant Sequence Type 1 Associated with Caprine Mastitis.

This study aimed to investigate the genomic and epidemiological features of a methicillin-resistant sequence type 1 (MRSA ST1) strain associated with caprine subclinical mastitis. An strain was isolated from goat's milk with subclinical mastitis in Paraiba, Northeastern Brazil, by means of aseptic procedures and tested for antimicrobial susceptibility using the disk-diffusion method. Whole genome sequencing was performed using the Illumina MiSeq platform.

CTX-M-15-producing Klebsiella pneumoniae ST273 associated with nasal infection in a domestic cat.

Objectives: The aim of this study was to investigate the genetic context of expanded-spectrum β-lactam resistance in a Klebsiella pneumoniae strain causing a hard-to-treat nasal infection in a domestic cat.

Methods: A K. pneumoniae isolate was recovered from a 4-year-old male cat hospitalised in a veterinary hospital in Paraíba, Northeastern Brazil.

Antimicrobial susceptibility profiles of spp. contaminating raw goat milk.

Background And Aim: Antimicrobial resistance poses a major threat to global public health. Foodstuff of animal origin can serve as potential vehicles for the dissemination of antimicrobial-resistant bacteria and resistance genes to consumers. In view of the lack of knowledge about antimicrobial resistance in bacteria associated with goat milk, the aim of this study was to report species-level identification and antimicrobial susceptibility profiles of a large collection of spp.

Occurrence of KPC-Producing in Psittaciformes Rescued from Trafficking in Paraíba, Brazil.

The emergence and spread of antimicrobial resistance pose a threat to public health globally. Antibiotic-resistant bacteria and genes can disseminate among environments, animals and humans. Therefore, investigation into potential reservoirs of multidrug-resistant bacteria is of great importance to the understanding of putative transmission routes of resistant bacteria and resistance genes.

The posthatch prophylactic use of ceftiofur affects the cecal microbiota similar to the dietary sanguinarine supplementation in broilers.

The prophylactic administration of ceftiofur to newly hatched chicks is a common practice in some hatcheries worldwide to mitigate early gastrointestinal infections caused by Enterobacteriaceae. In spite of the crucial role of the gut microbiome for the broiler's health, there is still limited information on how the microbial composition is affected by such procedure. We investigated the effects of posthatch prophylactic application of ceftiofur on the cecal microbiota of 14-day-old broilers fed regular or sanguinarine-supplemented diets.

Anaplasma marginale in goats from a multispecies grazing system in northeastern Brazil.

Anaplasma marginale, a tick-borne α-proteobacterium that causes significant economic losses for the cattle industry worldwide, has been increasingly detected in other animal species. This agent has been previously detected in buffaloes and goats co-grazed with cattle in Brazil. This study aimed to investigate the occurrence of A.

First reported genome of an mcr-9-mediated colistin-resistant Salmonella Typhimurium isolate from Brazilian livestock.

Objectives: To investigate the genetic context of colistin resistance in anmcr-9-harbouring Salmonella Typhimurium ST19 strain from swine in Brazil.

Methods: Minimum inhibitory concentrations (MIC) to colistin were determined by broth microdilution. Whole-genome sequencing was performed on an Illumina MiSeq system, followed by de novo genome assembly using SPAdes 1.

Draft genome sequence of mcr-1-mediated colistin-resistant Escherichia coli ST359 from chicken carcasses in Northeastern Brazil.

Objectives: Considering that polymyxin is a drug of last resort in the treatment of humans infected by multidrug-resistant bacteria, the occurrence of plasmid-mediated colistin resistance mcr gene among Gram-negative bacteria in foods must be investigated. We present herein the draft genome sequence of a phenotypically colistin-resistant Escherichia coli carrying mcr-1 in chicken carcasses from a public market.

Methods: Total genomic DNA from the strain was sequenced by means of the Illumina MiSeq.

First report of a livestock-associated methicillin-resistant Staphylococcus aureus ST126 harbouring the mecC variant in Brazil.

Staphylococcus aureus is a versatile and highly adaptable pathogen associated with a wide range of infectious diseases in humans and animals. In the last decades, concern has increased worldwide due to the emergence and spread of methicillin-resistant S. aureus (MRSA) strains shortly after this drug became a therapeutic option.
