ISSN Objective: To determine the antimicrobial presence and susceptibility of the coagulase-negative staphylococci group ECN, for its initials in Spanish in some cattle farms from Tolima, Colombia. Materials and methods: Using the California test for the diagnosis of mastitis CMT, for its initials in Spanish , quarters belonging to cows from five small production ranches from a region of central Tolima were evaluated. CMT positive samples were cultivated for bacterial isolation. The ECN found were tested for susceptibility to the antibiotics.

Our objective was to define the evolution and the clinical, radiological, microbiological, echocardiographic, and prognostic characteristics of left-sided NVE caused by CNS. An echocardiogram was performed in all suspected cases of endocarditis, and patients were followed up until a definite diagnosis was obtained. All patients underwent at least 1 physical examination, 1 electrocardiogram, 1 chest x-ray, 1 urinalysis, 3 blood cultures, and 1 transthoracic and transesophageal echocardiogram. The echocardiographic definitions of vegetation, abscess, pseudoaneurysm and fistula are described in a previous article. The indications for surgery include NYHA Class III or IV heart failure, fungal endocarditis, and uncontrolled infection persistent bacteremia or fever of more than 7 days' duration despite appropriate antibiotic therapy. Echocardiographic evidence of a periannular complication was not necessarily considered an indication for surgery. The onset of symptoms was acute The most important clinical, electrocardiographic, and radiographic characteristics are shown in Table 1.
