ABSTRACT
Campylobacter es un importante agente causante de enfermedad en el ser humano en nuestro medio. Los casos de bacteriemia ocurren principalmente en pacientes inmunosuprimidos y sondebidos frecuentemente a C. fetus. Sin embargo la bacteriemia es un episodio que también se ha observado enpacientes con enteritis por C. jejuni. Referimos dos pacientes con enteritis grave y bacteriemia, ambos con enfermedades concomitantes compatibles con inmunodepresión: uno con síndrome nefrótico de larga data y otro con hepatopatía crónica con cirrosis. Destacamos que los dos casos presentaron hematemesis y uno de ellos,enterorragia. Sugerimos prestar atención a la coloración de Gram durante el subcultivo de los caldos conhemocultivos, en busca de formas características de esta especie, y en ese caso emplear medios de cultivo enmicroaerofilia a 37 y 42 °C
Campylobacter is an importantagent of illness in human beings. Bacteremia occurs principally in the immunocompromissed host and is frequently due to C. fetus. Nevertheless bacteremia also has been observed in patients with enteritis due to C. jejuni. We refer two cases of patients with severe enteritis and bacteremia, both of them with immunosupressive concomitant diseases such as nephrotic syndrome and chronic cirrotic hepatopathy. Both patients presented hemathemesis

The role of campylobacter as a cause of bacterial diarrhea in young children in Alexandria, Egypt was investigated. Stools or rectal swabs were collected from 880 children [mean age 9.8 months] presenting to a hospital with the primary complaint of diarrhea and from 1,079 well children [mean age 8.8 months] attending a vaccination clinic. Isolation of campylobacter was significantly [p < 0.0002] more frequent from cases [17.2%] than from controls [6.4%]. Campylobacter was isolated from children presenting with diarrhea more frequently than Salmonella [3% isolation rate], Shigella [2% isolation rate], or other bacterial pathogens [1% isolation rate]. Isolation of Campylobacter was significantly more frequent during the rainy season [p < 0.0012]. These results implicate Campylobacter as a major bacterial cause of diarrhea for which young children are brought for medical attention in Alexandria, Egypt

Informa del primer aislamiento de Campylobacter jejuni en un niño con diarrea aguda, internado en el Hospital Ramón Madariaga de la ciudad de Posadas, Misiones. Se trata de un paciente de dos meses de edad que en enero de 1987 presentó un cuadro de diarrea aguda, con temperatura elevada, deshidratación moderada, vómitos y 6 a 8 deposiciones diarias. El estudio microbiológico de sus heces resultó negativo para Escherichia coli enterotoxigénica (ECET), eschirichia coli entero invasiva (ECEI), escherichi coli enteropatógena (ECEP) escherichia coli enterhemorrágica (ECEH), salmonella, shigella, aeromona y rotavirus, aislándose como único agente Campylobacter jejuni. Luego del tratamiento el paciente evolucionó favorablemente
