Tear ferning test in horses and its correlation with ocular surface evaluation.

Objective: To describe the tear ferning test (TFT) in healthy horses and its correlation with other parameters for evaluating the ocular surface.

Animals Studied: Thirty male and female adult healthy horses (60 eyes), of no defined breed.

Procedures: Tear sample was collected with a microcapillary tube, placed on the surface of a glass slide, and allowed to dry at room temperature.

Molecular epidemiology and antimicrobial susceptibility of Enterococci recovered from Brazilian intensive care units.

We studied the antimicrobial resistance and the molecular epidemiology of 99 enterococcal surveillance isolates from two hospitals of Brasilia, Brazil. Conventional biochemical tests were used to identify the enterococcal species and the disk diffusion method was used to determine their resistance profiles. Enterococcus faecalis (76%) and E.

Multilocus variable-number tandem-repeat polymorphism among Brazilian Enterococcus faecalis strains.

Multilocus variable-number tandem-repeat analysis (MLVA) for seven genomic loci was developed for Enterococcus faecalis. MLVA and pulsed-field gel electrophoresis (PFGE) resulted in 37 and 31 genotypes among 83 strains, respectively. Both typing schemes were highly concordant (90.
