Se comprueba que en las enteritis de los cerdos de la Provincia de Buenos Aires actúan indistintamente microorganismos solos o asociados. De 172 muestras bacteriológicas de necropsias y casos clínicos de enteritis de cerdos se aislaron: Escherichia coli 139; Salmonella 15; Proteus 10; Klebsiella 21; Sighella 2; Serratia 1; Pseudomonas 1; Campylobacter 28; Treponema 29 y Clostridum perfrigens 2. De las 139 cepas de E.coli un alto porcentaje correspondieron a los tipos somáticos 0149,0141,0138, y 08. Con los tipos somáticos 09,0141 y 04-0123 se reproduce experimentalmente la enfermedad de los edemas. Se detecta una elevada resistencia a las drogas con las cepas de E. coli aisladas en diferentes desórdenes entéricos, especialmente con los antibióticos de uso común en terapéutica veterinaria de nuestro país. Los serotipos más frecuentes de Salmonellas aisladas corresponden a S.cholera suis y S.tiphymurium. Treponema sp. y Campylobacter son los agentes bacterianos más comunmente aislados en la Disentería porcina. Se aisla C.perfrigens en 2 casos de enteritis necrótica. / The present work proved that pig enteritis in de province of Buenos Aires are caused by several kinds of microorganism that can act alone or associated in the gut. In a survey of 172 bacteriological samples taken from necropsied pigs with clinical sing of diarrhoea the following bacterias were isolated: E. coli 139;Salmonella 15;Proteus 10;Klebsiella 21;Sighella 2;Serratia 1;Pseudomonas 1;Campylobacter 28;Treponema 29 y Clostridium perfrigens 2. From the 139 strains de E.coli a high rate belonged to the somatic types 0149,0141,0138 y 08. With the somatic types of E.coli 09,0141 y 04-0123 the experimental reproduction of the Odenema disease was done. The strains of E.coli isolated from enteric disease showed high resistence specialy to the antibiotics of common use in the veterinary practice in Argentina. Within the Salmonella group.S.cholera suis and S.tiphimurium were the serotype isolated more frecuently. From pigs with pathological diagnosis of Swine Disentery,Traeponema and Campylobacter sp were isolated and from two cases of Necrotic a Clostridium perfrigens was recovery.
