A bacteriological, mycological and parasitological survey was carried out of wastewaters entering directly the municipal sewerage. The bacteria isolated from samples were Escherichia coli, Proteus sp., aerobic sporulates and a group of bacteria known as Gram negative nonfermenting (particularly the genera Pseudomonas, Alcaligenes). Cultivation of these samples showed no presence of the genus Salmonella. A mycological examination of wastewater samples yielded the following genera: Mucor, Peacilomyces, Fusarium and the species Calenularia fuliginea. Eggs of Ascaris suum were the dominant parasitic pathogens found in the wastewaters. Seldom diagnosed were parasitic pathogens of the following genera or species: Hymenolepis, F. hepatica, Trichuris, Oesophagostomum, Isospora, Eimeria, Taenia (listed in the order: max-min). The highest count of parasitic pathogens in wastewater samples during the operation was ascertained at the time between 8.30 and 12.30 hr
