Dermatophytosis caused by Trichophyton spp. in a Tenerife Lizard (Gallotia galloti): an immunohistochemical study.

Reports of dermatophytosis in reptiles are rare. This report describes the microscopical and immunohistochemical findings in a case of dermatophytosis caused by Trichophyton spp. in a 2-year-old Tenerife lizard (Gallotia galloti) with ulcerative and pustular skin lesions.

Multiple abscesses caused by Salmonella enterica and Corynebacterium pseudotuberculosis in a dromedary camel.

A rare case of arthritis, peri-arthiritis and pleurits associated with Salmonella enterica and Corynebacterium pseudotuberculosis infection in a dromedary camel is reported. Articular infections caused by Non-typhoidal Salmonella have been exceptionally described in human medicine. To our knowledge, this would be the first description of articular infections associated with Non-thyphoidal Salmonella in other mammals than humans.

Climatic effects on Salmonella survival in plant and soil irrigated with artificially inoculated wastewater: preliminary results.

The use of wastewater to replace other water resources for irrigation is highly dependent on whether the health risk and environmental impacts entailed are acceptable or not. Total count and species of microorganisms found in wastewater vary widely because of climatic conditions, season, population sanitary habits and disease incidence. Salmonella, one of the genera associated with waterborne diseases, lives in the intestine.

[Carriers of beta hemolytic streptococci from groups A, B, and C among schoolchildren in Las Palmas].

Background: Betahemolytic streptococci, particularly group A, are the most frequently isolated pathogen in the cases of acute pharyngotonsilitis in school-aged children. A study was carry out in school children of Las Palmas de Gran Canaria with the aim of knowing of the state of pharyngeral carriers of betahemolytic streptococci in Lancefield groups A, B and C.

Methods: A total of 1,002 healthy school children (520 boys and 482 girls) with ages ranging from 4 to 15 of aged were included in the study in which a pharyngeal exudate was obtained to detect the presence of betahemolytic streptococci.

[Sensitivity of groups A, B and C beta hemolytic streptococci to antibiotics].

We studied the susceptibility of 330 strains of beta hemolytic streptococci (60 group A, 125 group B, 145 group C) isolated from healthy school children in Las Palmas de Gran Canaria to 17 antibiotics. Only 2% of group A streptococci showed resistance to erythromycin, and 18% to 31% of the beta hemolytic streptococci strains were resistant to trimethoprim-sulfamethoxazole. All of these strains showed susceptibility to betalactam antibiotics, chloramphenicol, clindamycin and vancomycin.

Caseous lymphadenitis caused by Corynebacterium ulcerans in the dromedary camel.

Caseous lymphadenitis that affected the dorsal and ventral superficial lymph nodes in the left cervicothoracic region of a young dromedary camel is described. The agent isolated was Corynebacterium ulcerans. To our knowledge, this is the first description of purulent lymphadenitis caused by C.

Type I beta-lactamases of Enterobacter cloacae and resistance to beta-lactam antibiotics.

The interaction of type-I beta-lactamases from Enterobacter cloacae with diverse beta-lactam compounds was examined. The ability of penicillin and cefoxitin to induce beta-lactamase production in this strain was assessed. The effect of beta-lactamase inhibitors was measured on beta-lactamase extracts and on intact cells.
