The aim of the study is the evaluation of resistance patterns of E. coli in wastewater treatment plants without an evaluation of basic antibiotic resistance mechanisms. Investigations have been done in sewage, sludge and receiving waters from three different sewage treatment plants in southern Austria. A total of 767 E. coli isolates were tested regarding(More)
In a study of parasitological prevalence in El Salvador, stool specimens of 210 children with diarrhea were examined for intestinal parasites. In 104 cases (49%), intestinal helminths and protozoa were found. 53.4% of the specimens showed single infestation, 31.7% showed double. 3% triple and 1% quadruple infestation. Of the helminths, 31% were Trichuris(More)
Serum samples from 107 dentists, dental assistants, and dental technicians were examined with an indirect immunofluorescence test for antibodies to Legionella pneumophila SG1-SG6, L. micdadei, L. bozemanii, L. dumoffii, L. gormanii, L. jordanis, and L. longbeachae SG1 + 2. Thirty-six (34%) employees from dental personnel from 13 practices showed a positive(More)
Fungi, above all filamentous fungi, can occur almost everywhere, even in water. They can grow in such a quantity in water that they can affect the health of the population or have negative effects on food production. There are several reports of fungal growth in water from different countries, but to our knowledge none from Austria so far. The aim of this(More)
For some time now, antibiotic-resistant bacterial strains have been found in the human population, in foods, in livestock and wild animals, as well as in surface waters. The entry of antibiotics and resistant bacterial strains into the environment plays an important role in the spread of antibiotic resistance. The goal of the present study was to monitor(More)
In the course of a one-year study, 78 out of 239 samples from a Central European municipal water supply were found to contain Aeromonas species. Biotyping and hemolysin titers according to the criteria of Burke et al. (1) showed that almost 50% of the tested strains can be presumed to be enterotoxin-producing. The remaining microbiological parameters met(More)
To study the epidemiology of intestinal parasites in Ogun State, Nigeria, 479 stool specimens were examined at a hospital in Abeokuta during the rainy season in June 1986. Intestinal helminths and/or protozoa were present in 297 samples (62%). 41.1% of the specimens showed a single infection, 34% showed double, 20% triple and 5% quadruple infection. The(More)
In June 1986, 216 stool samples from Abeokuta (Ogun State, Nigeria) were examined for Salmonella. The samples were taken from people of all age groups: 162 samples were diarrheal. Salmonella could be isolated in nine samples (4.16%). The high prevalence of Salmonella among children under the age of 5 was striking; seven out of 79 samples (8.86%) were(More)
Sunlight exposure is considered to be the most important cause of "natural disinfection" in surface water environments. The UV-B portion of the solar spectrum is the most bactericidal, causing direct (photo-biological) DNA damage. In the present experimental study, the effect of solar radiation on the elimination of bacteria in water, especially in surface(More)
