Salmonellae in gulls and other free-living birds in the Czech Republic.

Cloacal swabs, collected from 756 wild synanthropic and exoanthropic birds of 57 species in the Czech Republic, yielded 32 strains of Salmonella typhimurium [phage types (PT) 141, 104 and 41], six isolates of S. enteritidis (PT 8, 4 and 6e), and one each of S. panama and S. anatum. Except for one S. enteritidis isolate from a grey-lag goose (Anser anser) and one S. typhimurium isolate from a coot (Fulica atra), all of the other strains were derived from black-headed gulls (Larus ridibundus), of which 24.7% were found to be infected. The black-headed gull might play a role in the dispersal of pathogenic salmonellae.

Use of pulsed field electrophoresis of DNA restriction fragments for comparing Listeria monocytogenes strains isolated from human infections and food in Austria.

Twenty-five Listeria monocytogenes strains of human and food origin were studied, using low-frequency-cleavage restriction endonucleases and pulsed field gel electrophoresis. Sixteen different restriction patterns were obtained using ApaI and SmaI. The human isolates showed profiles different from those of the food isolates, thus strongly suggesting that the two human infections selected for this study did not originate from the contaminated foodstuffs examined at the same time. This method allowed it to clearly distinguish between strains apparently similar [i.e. belonging to the same serovar and same origin (cheese samples from the same dairy plant)].

[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.

[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.

[The significance of detecting Corynebacterium equi in the conjunctiva of children in Cairo].

The probable correlations between certain Corynebacterium are discussed. Carpenter et al. (1976) describes a Corynebacterium equi-pneumonia in a patient with Hodgkin's disease; Gardner et. al. (1976) also reports on a case of pneumonia. Golub et. al. (1967) demonstrates a lung abscess resulting from Corynebacterium equi. Williams et. al. (1971) demonstrates a thoracic infection in an immunosuppressed patient. Although, our findings have been demonstrated only in conjunctivitis of children, hitherto descriptions of Corynebacterium equi in diseases of the lungs, especially in the case of a low immune response in certain sections of the population should be taken into account. Further investigations of the numerous dead donkeys with severe clinical symptoms of lung sequela are necessary.

A contribution to the situation of antibiotic resistance in Abeokuta (Ogunstate) and Minna (Nigerstate) in Nigeria.

After testing various chemotherapeutics the following conclusions could be drawn: Pseudomonas was sensitive only to gentamicin. Gentamicin, aminopenicilline + calvulanacid and cefoxitin were 100% effective against E. coli. Gentamicin also proved effective against Enterobacter (83%). Cefoxitin, aminopenicillin + clavulanacid, gentamicin and trimethoprim + sulfonamide were effective against Klebsiella. Concerning Proteus sp., cefoxitin showed best results (100%). Acinetobacter was 100% inhibited by gentamicin. Gentamicin was most effective (93% sensitivity) against Staph. aureus. Trimethoprim + sulfonamide and erythromycine showed resistance rate of 17%, cefalosporine and isoxazolylpenicilline a rate of 21%. Aminopenicillin and aminopenicilline + calvulanacid were most suitable against Enterococcus (100%).

[Significance of the occurrence of Aeromonas of various biotypes in the Third World].

In investigations carried out in the refugee camps of the Polisario (South Algeria), in the neighbourhood of the inhabitants of the waste disposal sites of Cairo and in the Ayoun el Atrous and Nema (Mauritania) regions also in the Bida and Minna hospitals. Aeromonas hydrophila and Aeromonas spec. were repeatedly found in the investigated material. Therefore, it was of particular interest for us to investigate this type of organism.

[Water studies of inhabitants of refuse disposal sites in Cairo. 1].

In two waste disposal sites in Cairo, drinking water samples from springs, drinking vessels and kitchens were investigated. Total germ count lay seldom below one thousand and ten million pro ml. Apart from various faecal germs, Aeromonas hydrophila was also found. The high occurrence of diarrhoeal diseases among the inhabitants of the waste disposal sites can be traced with certainty to the extremely bad drinking water quality.

First evidence of the leptospirosis natural foci of the serotype Saxkoebing in Austria.

The authors examined serologically and bacteriologically 129 wild living small mammals (9 species) in Neumarkt, in Styria. A total of 17 animals were positive (all Microtus agrestis), of these 10 serologically (6 with L. saxkoebing, 3 with L. grippotyphosa and 1 with L. sorexjalna) and 7 bacteriologically. Of the 7 isolated leptospirae-strains one did not survive up to typing, the 6 remaining were identified as L. saxkoebing. It is the first evidence of the existence of leptospirosis natural foci of the serovar saxkoebing in Austria and at the same time the first isolation of L. saxkoebing from Microtus agrestis in Central Europe. The serovar saxkoebing, which BORG-PETERSEN described in the year 1942 (1943) and isolated from the yellow-neck mouse (Apodemus flavicollis) is found in most European countries (KATHE and MOCHMANN, 1967), may, however not be found in some regions although its main reservoir, the yellow-neck mouse dwells, as SEBEK (1965) and SEBEK and ROSICKY (1974) drew attention to in Czechoslovakia. In Austria, in fact L. saxkoebing antibodies have been demonstrated in wild- and also domestic-animals (SEBEK, et. al., 1973b, 1976a, 1976b), however, a reliable proof of these serovars was not found.

[Microbiological measurement of air-borne bacteria at an office building].

Following a request of a cleaning firm microbiological measurings were carried out in (large building) office areas. Air was supplied through an air conditioner and all windows were locked and could not be opened. Office employees were on the opinion that illness had increased and felt endangered by colleagues' germs. To find out the reason of these complaints measurings were conducted in various rooms and floors also in the air conditioner. It must be stressed that in spite the continuous air conditioning, almost all doors were open to the corridors. This, declared one of the questioned employees had above all a communication expansion effect.

[The pathogen spectrum of the conjunctiva of inhabitants of refuse disposal sites in Cairo. I].

In Cairo's waste disposal sites conjunctivitis is frequently found resulting from the burning process of plastic, paper, etc.. Recurrent secondary contamination of the conjunctiva by pathogenic and non-pathogenic microorganisms often takes place; however, in certain germ species, the differentiation between pathogenic or non-pathogenic organisms within a damaged mucous membrane cannot be made. Furthermore, in this study, we have attempted to investigate germ reproduction during the application of PVP-eyedrops. However, our results cannot be conclusive because of the high environmental contamination, very low personal hygiene resulting from contaminated water and the constant exposure of samples to environmental contamination. Studies will be continued.
