WGS of intrauterine from cows with early postpartum uterine infection reveals a non-uterine specific genotype and virulence factors.

has been attributed to playing a major role in a cascade of events that affect the prevalence and severity of uterine disease in cattle. The objectives of this project were to (i) define the association between the prevalence of specific antimicrobial resistance and virulence factor genes in with the clinical status related to uterine infection, (ii) identify the genetic relationship between isolates from cows with diarrhea, with mastitis, and with and without metritis, and (iii) determine the association between the phenotypic and genotypic antimicrobial resistance identified on the isolated from postpartum cattle. Bacterial isolates ( = 148) were obtained from a larger cross-sectional study.

Agreement among deep nasopharyngeal sampling culture results for 3 different swab types in preweaning dairy calves.

Accurate isolation and identification of pathogens for an animal with bovine respiratory disease are of critical importance to direct appropriate decision-making related to the treatment of individual animals, as well as control and prevention options in a herd setting. The objective of this study was to compare nasopharyngeal sampling approaches to evaluate accuracy and agreement for the recovery of (MH) and (PM) from deep nasopharyngeal swabs (DNS) using 3 different swabs. Deep nasopharyngeal samples were collected from 45 dairy calves using 3 swabs: (1) double-guarded culture swab (DGS); (2) single-guarded culture swab (SGS); and (3) unguarded culture swab (UGS).

Antimicrobial resistance of Escherichia coli from dairy farms participating in an antimicrobial stewardship educational program for farm employees.

Antimicrobial use in food-producing animals is under increasing scrutiny due to the potential effect on the selection of antimicrobial-resistant bacteria that may be transmitted to humans by direct contact, with the food chain, or the environment. Novel data monitoring commensal Escherichia coli from dairy farms is essential for understanding antimicrobial resistance (AMR) patterns and their association with herd health management practices. The objectives of this study were to: (1) compare the prevalence of antimicrobial resistance in the E.

In vitro evaluation of the effect of transport medium, temperature, and time on the recovery of and .

Appropriate sample collection, storage conditions, and time for transport to the laboratory are important for an accurate diagnostic result. We evaluated the effects of transport storage medium type, time of storage, and storage temperatures on (MH) and (PM) recovery using an in vitro model simulation. A quantitative culture method, using colony-forming units per milliliter, was used to recover MH or PM by an in vitro model with cotton swabs.

Antimicrobial stewardship on the dairy: Evaluating an on-farm framework for training farmworkers.

Dairy farmworkers are commonly responsible for disease diagnosis and routine treatment decisions for cattle. This highlights the importance of farmworkers' knowledge and skills to successfully implement judicious use of antimicrobials in livestock production systems. The main objectives of this project were to develop and evaluate an on-farm educational program for farmworkers in antimicrobial stewardship in adult dairy cattle.

Evaluation of antimicrobial resistance and risk factors for recovery of intrauterine Escherichia coli from cows with metritis on California commercial dairy farms.

The goals of this study were to evaluate factors affecting recovery and antimicrobial resistance (AMR) in intrauterine E. coli in post-partum dairy cows with and without metritis from commercial California dairy farms. Using a cross-sectional study design, a total of 307 cows were sampled from 25 farms throughout California, from which a total of 162 intrauterine E.

Defining clinical diagnosis and treatment of puerperal metritis in dairy cows: A scoping review.

Although puerperal metritis (PM) is a common infectious disease in dairy cattle, there are currently discrepancies between clinical case definitions within and between available peer-reviewed literature and on-farms practices. The inconsistent use of PM criteria across studies and on-farms practices can result in disparities related to recommendations for treating cows, affecting judicious use of antimicrobials. The objective of this study was to systematically review the peer-reviewed literature for clinical signs used for case definition of PM.

Evaluation of Heat and pH Treatments on Degradation of Ceftiofur in Whole Milk.

Waste milk feeding practices have been implicated as a potential source for disseminating antimicrobial resistant bacteria among animals and the environment. Two interventions that have shown potential for degrading antimicrobial drugs in milk are heat and pH treatment. The aim of this study was to evaluate the effect of heat and pH treatments on the degradation of ceftiofur and ceftiofur free acid equivalents in milk at concentrations previously found in waste milk on dairy farms by spiking saleable pasteurized whole milk with ceftiofur sodium.

Liberating critical pedagogy of Paulo Freire in the scientific production of Nursing 1990-2017.

Objective: To analyze the theoretical and methodological application of Paulo Freire's critical pedagogy in the scientific production of nursing.

Method: An integrative review was carried out with consultation of the databases: LILACS, BDENF, MEDLINE, PUDMED and CINHAL. We included studies in the Spanish, English and Portuguese languages, published from 1990 to 2017.
