[10 years foodborne listeriosis--an evaluation].

Foodborne listeriosis outbreaks, which occurred in the past 10 years, have raised new questions in listeriosis epidemiology. The renewed interest in listeriosis and Listeria monocytogenes has resulted in various efforts, which enormously enriched the knowledge about his relatively rare, but because of the high mortality rate, important infectious disease as well as about its causative agent. New data concerning epidemiology and therapy of human listeriosis as well as new experience with Listeria monocytogenes regarding virulence, typing, isolation, identification, occurrence in food and environment, behaviour towards disinfectants etc. have changed the view of human listeriosis prevention. The new aspects are summarized in this review.

[Testing of industrial repellents against gnats and horseflies].

According to the Austrian Cosmetic Recommendation a minimum period of protection of 2 hours is to be provided. This applies to the preparation on the market with the substance "Merck 3535" in aqueous concentration in the tested area. However, this protection period was not achieved for horseflies. In test trials the characteristic of the individual nuisance should be taken into account.

[Air pollution emissions and changes in lung function].

Among the environmental hazards in a modern industrial society, air pollutants are of major significance. They can directly affect the cells of the bronchopulmonary system and lead to an irritation of the epithelial and immunocompetent cells. This results in a decreased secretion of immunoglobulin A, and, consequently, a decreased resistance against infections. Thereby pathogens, especially bacteria, may lead to an inflammation of the respiratory tract. Apart from the direct toxic effect of their pollutants, recurrent inflammations eventually lead to small airway obstruction. The spirometric parameters FVC, FEV1 and MEF50 were reduced. IgA concentration in the saliva was determined by means of immunodiffusion and was found to be reduced when compared to a less exposed group. A series of pathogenic germs were isolated from various mucous membranes (conjunctiva, nose/throat). The median immissions for the children examined were 1.345 mg/m3 SO2 and 0.189 mg/m3 HCl.

Bacteriological investigations and resistance patterns in beef and goat's meat in Colombo's slaughter-house.

A high contamination rate was found in meat of slaughtered cattle and goats at the time of this study. Certain organisms were isolated from meat and also from wounds of slaughter workers. A high antibiotic resistance pattern was found - in some instances. Following observations of high surface meat contamination, associated with high antibiotic resistance, it must be assumed, that these highly resistant organisms can also be directly transmitted to humans by transport, transaction and by food preparation. This must be taken into consideration in the actual therapeutics.

On the drinking water situation on the Cape Verde Islands (Island of Santiago).

On the Cape Verde Islands drinking water investigations were made. The drinking water was tested in chemical and bacteriological respects as well as on amebas and rotaviruses. The isolated germs were investigated on their reaction against several antibiotics and chemotherapeutics by means of the agar diffusion test. The changing of drinking water quality from water-supply-places to the households was investigated as well. According to the fact, that only 10.6% of 207 public water supplies investigated show drinking water quality after ONORM, and that nearly 30% and 80.2% of them contained E. coli and coliforme germs respectively, the urgency of extensive sanitations of water supplies on the Cape Verde Islands is evident.

[Serological studies of cytomegalovirus in the Melut district, South Sudan].

Out of 1071 investigated patients had antibodies in 73.7% against Cytomegalovirus. 99 ambulant Kala-Azar-patients reacted positive in 33%. Inhabitants of different villages have shown 35.2 to 50% positive reactions. Patients with hepato-splenomegaly in 94% and patients with diarrhoea and fever in 81% were positive.

Ocular infection investigations in Cairo's waste disposal sites. PVP-iodine treatment trials.

Investigations were carried out in Cairo's waste disposal sites of the inhabitants of all age groups. Germ-spectrum was analyzed before and after PVP-Iodine-treatment. However, any further dilution of PVP-Iodine in the treatment had no effect on the germspectrum, as hydrochloric acid formation in air, produced by plastic burning causes severe eye irritation and a constant lacrimation. The high germ count of the air in the dwellings and the environment is an additional source of contamination to the conjunctiva.

Leptospirosis in man, in wild and in domestic animals at waste disposal sites in Cairo.

The authors examined 65 Rattus rattus, 28 pigs, 12 donkeys, 67 goats, 5 sheep, 1 cow and 1 dog as well as 196 inhabitants at two settlements on the waste disposal sites at the periphery of Cairo. Rattus norvegicus were positive in 55.4% for L. ictero-haemorrhagiae, pigs in 14.3% for L. pomona and in 3.6% for L. ictero-haemorrhagiae. 2 out of 12 donkeys were positive for L. pomona, 1 of them for L. pyrogenes and L. icterohaemorrhagiae as well, goats in 1.5% for L. grippotyphosa. Human sera reacted positively in 8.7% of the cases, 7.1% of which with L. bratislava, 1.0% with L. icterohaemorrhagiae and 0.5% with L. grippotyphosa and L. sejroe respectively.

[Serologic studies of listeriosis antibodies in dogs in Greece].

In an epidemiological study of dogs carried out in Greece, antibodies against listeriosis were demonstrated in the slow-agglutination and the complement-fixation-reaction. Depending on the dogs' place of origin CFR titers were found in 6.1% to 51.1%. CFR-titers could be confirmed in a comparative investigation with the slow-agglutination-test.

[Toxoplasmosis in dogs in Greece].

In Greece, not only raw meat feeding but also the possible faecal transmission of disease from the vast amount of strayed domestic cats play an important role in the incidence of toxoplasmosis among dogs. This must be concluded from the high contamination rate of 21.2% to 30.8% in all four presented investigations.
