[Medical wastes. 2. Comparative studies of the microbial contamination of wastes from medical practices of different disciplines and household garbage].

Medical consulting room wastes of 7 disciplines were investigated quantitatively and qualitatively for nosocomial infective agents. 20-25 samples from each consulting room were examined for 3 months. The results were compared with those of household refuse and hospital wastes. The whole content of a waste bag was suspended without a preceding sorting and the eluate was microbiologically examined. The results of the investigations proved, that the germ concentration of the medical consulting room wastes was less than that of household refuse. The median for all investigated germ groups was less than 1 log(10)-step compared-to household refuse. The statistical analyses confirmed highly significant differences (p less than 0.001) for total germ concentration, thermoresistant obligate aerobic and facultative anaerobic bacteria and bacteria spores. Exceptionally the paediatric consulting room wastes show smaller differences (p less than 0.01) between the household refuse for obligate and facultative anaerobic bacteria, thermoresistant obligate and facultative anaerobic bacteria and bacteria spores and D-streptococci. From the comparison of total germ concentration for medical wastes from conservative disciplines and household refuse resulted that wastes from medical consulting rooms are less contaminated with nosocomial infective agents than household refuse and hospital wastes. In conclusion wastes from medical consulting rooms can, similar to hospital wastes, be disposed together with household refuse.

Problems of housing and health of people utilizing the garbage in Cairo from the viewpoint of medical entomology.

More than 50 arthropod species were found at two dumping-grounds with dwelling-places (Mokattam and Ezbet el Nakhl) in Cairo. Their importance was evaluated from the epidemiological and epizootological points of view. Of primary importance is the great prevalence of the fleas (Xenopsylla cheopis) on brown rats (Rattus norvegicus), since the rats are in a close contact with people. They are often simultaneously parasitized with another flea species, Ctenocephalides felis felis, which is very frequent in the studied localities, occurring not only on people and dogs, but also freely in the whole area inhabited by people. Significant is also the large number of ticks (Rhipicephalus sanguineus) and synantropic flies of epidemiological importance. There is a mass occurrence particularly of the species Musca domestica vicina, Musca sorbens and Piophila casei. Attention is paid also to natural reducers of these flies.
