RESUMO
A descriptive study of cases was conducted in which 781 sera were investigated using the indirect immunofluorescent technique with antigens of Babesia bovis and Babesia bigemina at the National Center for Agricultural Health. Of them, 371 came from agricultural workers and 410 from donors in the province of Ciego de Avila. It was started from dilutions of 1/64. An epidemiological survey was done to each seropositive so as to know the risk factors. The test of difference of proportions was used to compare the percentages of positives. The geometrical means were calculated in both group and they were compared with the U test of Mann Whitney. Among the agricultural workers it was detected 7% with antibodies against 3.9% of the donors (p < 0.05). It was found a greater circulation of Babesia bovis than of Babesia bigemina.

A clinical epidemiological study of reported leptospirosis cases in adults in the period 1984-1988 in the province Ciego de Avila, Republic of Cuba, was conducted. The most frequent symptoms and signs were: fever, headache and arthralgia. Eighty-two percent of patient were anicteric. The most frequent presumptive diagnosis included leptospirosis, virosis, and febrile syndrome. Sporadic cases predominated over cluster cases. The incidence of cases was higher from October to December. Sixty-five percent of patients were 36 years old or less. The serogroups detected more frequently were Leptospira interrogans var. Australia and Leptospira interrogans var Pomona. The high range of diagnostic and presumptive approaches with cases show that most cases would go undetected if an active surveillance is not implemented.

Para contribuir al manejo diagnóstico del niño con diarrea aguda (EDA) realzamos un estudio a 793 lactantes, recigiéndose anamnesis, examen físico y el resultado de estudios parasitológicos y cultivos de las heces fecales. Se obtuvo un 67.6 porciento de positividad, resultando las bacterias el agente causal más frecuente. La determinación de leucocitos en heces fecales resultó de gran utilidad en el diagnóstico de las infecciones enterales, sobre todo las producidas por gérmenes enteroinvasivos. Fue detectado más de un agente causal en 96 pacientes para un 12 porciento. La fiebre, los vómitos y las manifestaciones catarrales pueden o no acompañarse a cualquier enteropatógeno, independientemente de su mecanismo de acción. (AU)
