A study of 121 patients with acute diarrhea was made at the Pediatric Clinic of the Santa Casa de S. Paulo (the S. Paulo Charity Hospital). Etiological diagnosis of 121 cases was carried out through the classical bacteriological method and direct fluorescent antibody tests for the identification of E. coli. The antibiotic sensitivity of these bacteria to different antimicrobials was determined by the Minimum Inhibitory Concentration (MIC) method. Fifty-six positive cases were found; 89.3% of which corresponded to different serotypes […]

Tests were performed for the determination of IgM levels (by simple radial immunodiffusion) and antibodies for syphilis (FTA-ABS-IgG and IgM, VDRL and Wassermann (W)) and toxoplasmosis (indirect immunofluorescence IgG (IFI-IgG) and IgM (IFI-IgM)) in 408 new-borns (NB) sera at the University Hospital of the Faculty of Medicine of Ribeirão Preto, USP, selected at random from July 1 to October 9, 1981. Only 3 NB showed greater than normal values of IgM levels in serum, but no clinical or laboratory diagnosis […]
