Leptospirosis in the Melut district--upper Nile province (south Sudan)--an overview.

The authors examined 195 domestic animals for leptospirosis serologically in Sudan (170 cattle, 7 sheep and 18 goats) and 771 wild animals (36 species) with 13 serovars from 13 serogroups. 54% of domestic animals namely, 108 cattle and 1 sheep were positive in titer levels of 1:400 and higher. Cattle sera with the serovars of the serogroup Icterohaemorrhagiae were 2.4% positive with Cynopteri 2.4%, Autumnalis 3.5%, Australis 1.2%, Pomona 2.9%, Grippotyphosa 2.9%, Hebdonadis 17.1%, Bataviae 9.4% and Tarassovi 50.6%. Only one Numida meleagris of the 54 wild birds (14 species) was positive in low titer level of 1:100 with L. canicola. Seventy (9.8%) of the 717 wild mammals (22 species) examined were positive namely with the serovars of the serogroups Icterohaemorrhagiae 3.4%, Javanica 3.0%, Pomona 2.0%, Grippotyphosa 0.7%, Hebdomadis 0.4%, Ballum, Australis, Pyrogenes, Bataviae each 0.3% and Cynopteri 0.1%, whereby sera from 7 animals reacted simultaneously with the serovars of two serogroups. With regard to the species, positive reactions were found in Erinaceus albiventris, Eidolon helbum, Cercopithecus aethiops, Genetta spec., Canis adustus et aurus, Felis silvestris, Leptailurus serval, Arvicanthis niloticus, Mastomys spec., Mus spec., Gazella spec., Tragelaphus spec. The positivity in rodents was very low - 1.2%.

Environmental protection and its trends in developing countries.

On instances of some worldwide problems of environmental protection, the authors refer to the fact, that a target of industrial countries is to help to the developing countries. Mainly it means an aim in such sense, that the dangerous failures and faults which happened in the past, should not be repeated as a consequence of temporaneous economical problems in the Third World. In the long run it is a common interest of all and certainly a sufficient motivation of a commonly coordinated effort in this field. It is at most desirable, that all developing projects, from a simple water supply to the integrated developing concepts, for example eco-agriculture projects, correspond with the national interests as well as with the specific requirements of environmental control.

Accumulation of heavy metals in animals. Part 1: Lead and cadmium contamination in some wild animals.

The accumulation of the heavy metals lead and cadmium in the liver of wild animals reveals when also not so alarming, an anthropogenic source of influence from industrial procedures. A great deal of the high mean values distributed in the literature appear to be more a problem of data evaluation, where few, but higher deviation values caused by sample contamination distorts the picture. Apart from samples with heavy lead deposits due to the gun shot, it is not necessary to advise against the consumption of venison.

Accumulation of heavy metals in animals. Part 2: Heavy metal contamination of fish in Styrian waters.

The kidneys of fish from five different regions of Styrian waters were investigated for their content of cadmium, lead, copper and zinc. 72.6% of fish demonstrated a zinc content below 130 ppm, cadmium content lay with 69% under 750 ppb. Lead concentrations were slightly higher, however values above 1 ppm were demonstrated only in 27.4% of cases. The copper content in the kidneys of fish was significantly higher; revealing in 28.8% a copper content of above 8 ppm.

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.

[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.

Microbiological and chemical analysis of drinking water in southern India (with special consideration of Aeromonas species).

Analyses of drinking water taken from central and individual water supplies in Southern India (Idukki/Kerala) showed bacterial counts of 10(3)-10(6). E. coli were found in 11% and 28% of the samples. Aeromonads were identified more frequently than E. coli at 44% in central and 38% in individual water supplies. Due to this high rate of contamination, Aeromonas spp. must be considered as a possible cause of diarrhoea and other infections in this area.

[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.
