ABSTRACT
Las infecciones originadas por bacterias del género Salmonella son una de las principalescausas de pérdidas económicas en la industria avícola, se caracterizan generalmentepor la presentación de cuadros diarreicos y septicémicos que llevan a las aves a unamarcada disminución en la producción y a la muerte. En Colombia, debido al efectonegativo que produce Salmonella spp. en las aves, y con el objetivo de poder controlarla enfermedad, se utiliza una gran variedad de productos antimicrobianos, de los cuales no se posee suficiente información acerca de su comportamiento en cuanto asensibilidad y resistencia frente a las cepas de Salmonella spp. de campo. El objetivo de este estudio fue determinar la respuesta de 20 cepas de Salmonellas grupo D (móviles einmóviles) aisladas de aves ponedoras comerciales en Colombia frente a diferentes antimicrobianos. Para su aislamiento y tipificación se utilizaron técnicas microbiológicas convencionales, pruebas bioquímicas, serológicas y pruebas de susceptibilidad a los antibióticos por difusión en agar. Los resultados revelaron una resistencia total hacia la estreptomicina, seguida de altas resistencias para tetraciclina y florfenicol, y una menor resistencia a productos como fosfomicina y cloramfenicol.
Infections caused by Salmonella bacteria are a major cause of economic losses in thepoultry industry, because caused mainly by the presentation of diarrheas and septicemic birds leading to a marked decrease in the production death. In Colombia due to the negative effect by Salmonella spp. in poultry, and with the aim of controlling the disease, the people have been using a variety of antimicrobials, which do not possess sufficient information about its behavior in terms of sensitivity and resistance againststrains of Salmonella spp. field. The aim of this study was to determine the response of20 strains of Salmonella group D (mobile and non mobile) isolated from commercial laying hens in Colombia against different antimicrobials. For the isolation and characterization are using conventional microbiological techniques, biochemical tests, serological testing and antibiotic susceptibility by agar diffusion. The results revealed a total resistance to streptomycin, followed by tetracycline and Florfenicol and less resistance to products such as Fosfomycin and chloramphenicol.

Acute gastroenteritis due to Salmonella species, which usually improves on conservative treatment, can progress to sepsis and extraintestinal focal infection in very young infants. Frequent sites for extraintestinal infections are meninges, bone, joints, spleen and intravascular sites but scrotal abscess due to salmonella in children has been very rare. Literature search revealed only one newborn case of scrotal abscess with bacteremia due to salmonella group D which developed after circumcision. We, herein, report a 42 day old infant who initally presented with diarrhea that progressed to sepsis and scrotal abscess. Despite the use of susceptible antibiotics, the patient improved only after surgical drainage.
