ABSTRACT
Prevalence of CMV and toxoplasmosis antibodies were determined among normal newborn infants, suspected congenital neonates and pregnant women. Seropositive rates of CMV and toxoplasmosis were similar. Most of the pregnant women had CMV antibodies. The in-house ELISA for detection of Toxoplasma antibodies was developed and compared with the commercial kit with sensitivity and specificity of 90.47% and 96.74% respectively.

The prevalence of CMV antibody in various groups of Thai population was studied. Pregnant women and young children had been infected with CMV more than the other studied groups. Children of both sex had equal chance of getting CMV infection while the risk of CMV infection in adult between male and female was significantly difference (p < 0.001). Pregnant women had higher chance to get CMV infection than normal women. Prevalence of CMV antibody at present was similar to previous studies.

Axenic cultures of Giardia intestinalis trophozoites were successfully established from human fecal specimens and rectal swabs from dogs using sucrose gradient centrifugation to separate the cysts from fecal material, the excystation method of Robert-Thompson et al. and culture of the preparation in TYI-S-33 medium supplemented with human serum, vitamin mixture and piper acillin and amikacin antibiotics, respectively. Fungal contamination could be controlled by amphotericin B at 10 micrograms per ml of medium. Clones of the parasites were obtained using a combination of dilution method and micromanipulation technique.

The in vitro activity of drugs, namely dehydroemetine, ornidazole, metronidazole and tinidazole were determined against the locally isolated strains of E. histolytica in Thailand. The test was performed in liquid monophasic medium, i.e. liver marmite serum medium. In all, locally isolated strains from thirty hosts studied, the minimal inhibitory concentration (MIC) for dehydroemetine ranged from 0.125 to 1 microgram/ml, ornidazole ranged from 0.0625 to 0.25 microgram/ml, metronidazole ranged from 0.0625 to 0.125 microgram/ml, and tinidazole ranged from 0.0625 microgram/ml to 0.25 microgram/ml. The MIC of dehydroemetine was significantly different from ornidazole, metronidazole and tinidazole. Metronidazole was superior to that of dehydroemetine but was not significantly different among ornidazole, metronidazole and tinidazole.
