Identification of equine mares as reservoir hosts for pathogenic species of .

Equine leptospirosis can result in abortion, stillbirth, neonatal death, placentitis, and uveitis. Horses can also act as subclinical reservoir hosts of infection, which are characterized as asymptomatic carriers that persistently excrete leptospires and transmit disease. In this study, PCR and culture were used to assess urinary shedding of pathogenic from 37 asymptomatic mares.

Concurrent colonization of rodent kidneys with multiple species and serogroups of pathogenic .

Rodents are important reservoir hosts of pathogenic leptospires in the US Virgin Islands. Our previous work determined that trapped rodents were colonized with serogroup Ballum ( = 48) and/or serogroup Icterohaemorrhagiae ( = 3). In addition, nine rodents appeared to be colonized with a mixed population comprising more than one species/serogroup.

Genomic Features of Antimicrobial Resistance in Isolated from Dogs with Pyoderma in Argentina and the United States: A Comparative Study.

is the most common opportunistic pathogen in dogs and methicillin resistance (MRSP) has been identified as an emerging problem in canine pyoderma. Here, we evaluated the antimicrobial resistance (AMR) features and phylogeny of isolated from canine pyoderma cases in Argentina ( = 29) and the United States ( = 29). 62% of isolates showed multi-drug resistance.

DNA Capture and Enrichment: A Culture-Independent Approach for Characterizing the Genomic Diversity of Pathogenic Species.

Because they are difficult to culture, obtaining genomic information from spp. is challenging, hindering the overall understanding of leptospirosis. We designed and validated a culture-independent DNA capture and enrichment system for obtaining genomic information from complex human and animal samples.

Animals Exposed to Serogroups Not Included in Bacterins in the United States and Puerto Rico.

Leptospirosis is a worldwide zoonotic disease. Pathogenic leptospires colonize the renal tubules and genital tract of animals and are excreted via urine. Transmission occurs via direct contact or through contaminated water or soil.

First report of Staphylococcus pseudintermedius ST71-SCCmec III and ST45-ΨSCCmec from canine pyoderma in Argentina.

Staphylococcus pseudintermedius is an opportunistic pathogen commonly associated with skin infections in dogs. Twenty-three methicillin-resistant S. pseudintermedius (MRSP) isolated in Argentina from dogs with pyoderma were analyzed using whole genome sequencing (WGS) and classified into sequence types (ST) by multilocus sequence typing (MLST) and staphylococcal chromosome cassette mec (SCCmec) types.

Isolation of serovar Grippotyphosa from a red panda () after antimicrobial therapy: Case report.

A 1-year-old female red panda started showing symptoms of illness, including lethargy, anorexia, abdominal discomfort, and vomiting, shortly after transfer to a new zoo. Serum was tested for leptospirosis using the microscopic agglutination test, and a titer of 1:25,600 to serogroup Grippotyphosa was detected. Antimicrobial treatment with doxycycline was initiated.

serovar Hardjo and serogroup Pyrogenes isolated from bovine dairy herds in Puerto Rico.

Leptospirosis is one of the most common zoonotic diseases in the world and endemic in the Caribbean Islands. Bovine leptospirosis is an important reproductive disease. Globally, cattle are recognized as a reservoir host for serovar Hardjo, which is transmitted urine, semen, and uterine discharges, and can result in abortion and poor reproductive performance.

Antimicrobial resistance and genomic characterization of serovar Senftenberg isolates in production animals from the United States.

In the USA, subspecies serovar Senftenberg is among the top five serovars isolated from food and the top 11 serovars isolated from clinically ill animals. Human infections are associated with exposure to farm environments or contaminated food. The objective of this study was to characterize Senftenberg isolates from production animals by analyzing phenotypic antimicrobial resistance profiles, genomic features and phylogeny.

Bovine Leptospirosis Due to Persistent Renal Carriage of Serovar Tarassovi.

Leptospirosis is a global zoonotic disease that causes significant morbidity and mortality in human and animal populations. is a leading cause of human disease, and . is a leading cause of animal disease.

Antimicrobial resistance and genomic characterization of Salmonella Dublin isolates in cattle from the United States.

Salmonella enterica subspecies enterica serotype Dublin is a host-adapted serotype in cattle, associated with enteritis and systemic disease. The primary clinical manifestation of Salmonella Dublin infection in cattle, especially calves, is respiratory disease. While rare in humans, it can cause severe illness, including bacteremia, with hospitalization and death.

Protracted Outbreak of Salmonella Newport Infections Linked to Ground Beef: Possible Role of Dairy Cows - 21 States, 2016-2017.

In January 2017, CDC identified a cluster of Salmonella enterica serotype Newport infections with isolates sharing an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern, JJPX01.0010 (pattern 10), through PulseNet, the national molecular subtyping network for foodborne disease surveillance. This report summarizes the investigation by CDC, state and local health and agriculture departments, and the U.

Comparison of whole genome sequencing to restriction endonuclease analysis and gel diffusion precipitin-based serotyping of Pasteurella multocida.

The gel diffusion precipitin test (GDPT) and restriction endonuclease analysis (REA) have commonly been used in the serotyping and genotyping of Pasteurella multocida. Whole genome sequencing (WGS) and single nucleotide polymorphism (SNP) analysis has become the gold standard for other organisms, offering higher resolution than previously available methods. We compared WGS to REA and GDPT on 163 isolates of P.
