La Septicemia por Aeromonas moviles (SAM) es la enfermedad infecciosa mas prevalente en la piscicultura nacional. Las dificultades para el acceso en el pais a formulaciones especificas para acuicultura y la carencia de informacion farmacologica para las especies y condiciones de cultivo nacionales, provocan en muchos casos un uso indebido de los farmacos con el consecuente riesgo de desarrollo de resistencia a los antimicrobianos. El objetivo de este trabajo fue caracterizar los perfiles de resistencia a los antimicrobianos desarrollados por un numero representativo de aeromonadales aislados de peces cultivados en nuestro pais. Para ello se empleo el metodo de difusion en placa segun protocolo estandarizado por el Clinical and Laboratory Standar Institute. Los antimicrobianos evaluados fueron: amoxicilina acido clavulanico, ampicilina, ampicilina dicloxacilina, enrofloxacina, eritromicina, nitrofurantoina, oxitetraciclina, penicilina, tiamfenicol y sulfametoxazole-trimetropim.

The typical disease presentations are cutaneous leishmaniasis (CL), mucocutaneous leishmaniasis (MCL) and visceral leishmaniasis (VL).

However, the most cosmopolitan species is L. infantum, one of the most important etiological agent of VL, since can be transmitted by sand flies of the Old and New World.

Los potenciales evocados somatosensitivos (PESS) pueden brindar informacion de las lesiones en la conduccion nerviosa, tanto por dano axonal como de la mielina. En la esclerosis multiple, permiten detectar precozmente lesiones que se sospechan a nivel clinico.

Se registraron a nivel craneal y espinal los PESS obtenidos por estimulacion del nervio tibial de caninos con Distemper y caninos sanos. Se demostro un aumento de la latencia de la onda P1 y una disminucion de la amplitud N1-P2 en el registro craneal. Asi mismo, existio un aumento en la amplitud N2-P2 en los registros espinales.

The neuropathological changes that occur in this presentation are similar to the ones present in human demyelinating diseases like multiple sclerosis. Somatosensory evoked potentials (SSEPs) can provide information about axonal and/or myelin lesions. In multiple sclerosis patients, the SSEPs allow the early detection of subclinical lesions. The aim of this study was to determine if there was an alteration in the response of SSEPs of the tibial nerve in canines with Distemper. Cranial and Spinal SSEPs were recorded by means of tibial nerve stimulation in dogs with Distemper and in healthy dogs. There was an increase in the P1 wave latency and a decrease in the N1-P2 amplitude of the cranial SSEPs. Furthermore, an increase in N2-P2 amplitude was observed in the spinal SSEPs.
