RESUMEN
Abstract Purpose: To evaluate the response of aging rats with sepsis to two different antibiotic regimens. Methods: The study was conducted with 30 aging rats (18 month-old) with autologous feces peritonitis. The animals were divided into three groups: Group 0 received no therapeutic intervention (control), while Group 1 received a single dose of 40 mg/kg meropenem and Group 2 received a single dose of 20 mg/kg moxifloxacin. The intervention in both Groups was made 6 hours after induction of peritonitis. The animals were followed up to 15 days for evaluating morbidity and mortality. The weights at baseline were similar in all groups. Results: At the end of follow-up, weight loss was significantly greater (p=0.0045) in Group 0 (non-intervention controls). Culture from a blood sample at the end of follow-up was positive in all the animals in Group 0, in two animals in Group 1 and in four animals in Group 2. Morbidity/mortality was significantly higher in Group 0 compared to both Groups 1 and 2 (p=0.003) but the scores were not significantly different between Groups 1 and 2 (p=0.6967). Conclusion: Both antibiotic regimens rendered promising results for the treatment of fecal peritonitis.

Se present ael caso de una paciente de 50 años que durante la internación por un severo cuadro de artritis reumatoidea, desarrolló una bacteriemia por Bacteroides distasonis a partir de una colecistitis no reconocida y cuya expresión final fue una meningitis. La evolución de la paciente no fue favorable por no haber recibido la terapia antibiótica adecuada en forma temprana. El diagnóstico etiológico fue realizado a través del estudio microbiológico del líquido cefalorraquídeo transportado y cultivado en aero y anaerobiosis. Este procedimiento es importante en aquellos pacientes que presentan procesos infecciosos agudos o crónicos pulmonares, intraabdominales o craneofaciales y que además son inmunocomprometidos. En tales casos debe incorporarse al esquema terapéutico inicial un antibiótico efectivo en el tratamiento de los gérmenes anaerobios que pudieran estar involucrados
