In order to establish the course of infection, virulence and pathogenicity, a Paraguayan Trypanosoma cruzi strain isolated from a 12 year old patient in 1989, Balb/c mice were inoculated, and the number of parasites were determined by direct parasitemia (micromethod). Pathogenicity were tested by perform...
The polymerase chain reaction (PCR) was usedto evaluate the course of treatment of an acutely infected patient with Trypanosoma cruzi. The reactions were performed using a primer pair (TCZ1 and TCZ2) which prime the amplification of a highly repetive 195-bp T. cruzi genomic DNA. Treatment with benzonidaz...
Complex II (Succinate-ubiquinone oxidoreductase) is an importnat enzyme complex for the tricarboxylic acid cycle and the aerobic respiratory chain of motochondria and procaryotic organisms (12, 24). Complex II catalyzes the oxidation of succinate to fumarate (Succinate dehydrogenase: sdh) and transfers i...
Three Cabus apella monkeys were infected with 3.5 x 10 sobre 5 cells of Trypanosoma cruzi Y strian in order to evaluate the parasitemia and to study the behavior of the parasites in the mammalian host for a one-year period. The parasitemia was determined by hemoconcentraction. In the there monkeys, circu...
Feces from 64 Cebus apella monkeys were examined by the MGL method. The monkeys have been kept in captivity at IICS. Larvae resembling those of Strongyloides were found in 25 percent of the animals, eggs resembling thosse of Strongyloide in 39 percent of the animals and eggs resembling those of Cestode ...
From April 1987 to December 1990, a total of 3895 persons participated in our anonymous HIV-antybody prevalence study in groups at risk for sexually-acquired HIV infection. Male travestied prostitutes had the highest HIV-antibody seroprevalence (> 30 precent). Seventy five percent of all known male trave...
Reported numbers underestimate the true occurrence of pediatric AIDS: There is underreporting or delay in reporting because infected children ofthen have nonspecific signs and symptoms that may not meet the CDC surveillance case definition for pediatric AIDS. Infants and children under 13 years of age wi...
One-hundred fish samples of different species, capture between October and Novenber 1989 from Paraguay and Paraná rivers, were evaluated in terms of total mercury content in fresh meat. Specimens were captured at Bahía Negra, Valle-mí, Concepción, Asunción and Pilar on Paraguay river, and at Ayolas ...
An etiological study of bacterial diarrhea in infants under five years of age in Paraguay from May to July of 1990 was done. Enteropathogenic E. coli (EPEC) strains of known serogroups were isolate from 35.8 percent of the patients with diarrhea, Salmonella spp. were isolated from 15.1 percent , enteroto...
In order to determine the incidence and the etiology of the sexually trasnmitted diseaes (STD) 500 women, belonging to a high risk group (prostitutes), were studied from August, 1989 to Octuber 1990, and bacteriological and mycological studied were performed. Also, a questionnaire comprising detailed sex...
