[Natural foci of Lyme borreliosis].

The submitted paper provides evidence that tick-borne borreliosis described as Lyme disease, is a disease with natural focality. Its properties, despite the widespread occurrence, classify it in this group. The authors give a characteristic of the disease, of hitherto known vectors, the main reservoir animals in America and Europe. Attention is drawn to the importance of deer and the effect of their increasing numbers on the spread of ticks and the disease. The great adaptability of the causal agent is apparent from the wide areas of its occurrence, incl. the Holoarctic, Aethiopian and Australian area. The complicated relations of the natural foci of tick-borne borreliosis must be investigated in particular under Central European conditions.

[Urban cycles of zoonotic mycoses].

Based on their own results assembled during mycological examinations of 9958 subjects, 5496 animals and 648 specimens of non-animal substrates, and using data from the literature, the authors tried to formulate general laws concerning the prevalence of causal agents of mycoses with a zoonotic character which circulate steadily in urban areas: Microsporum canis, M. persicolor, Trichophyton mentagrophytes, M. equinum and T. equinum, T. verrucosum, some geophilic dermatophytes, Cryptococcus neoformans and Emmonsia crescens. In the characteristics of different urban cycles they used as a basis the evaluation of the prevalence of reservoir animals and reservoir substrates on the territory of towns and the evaluation of the most frequent routes of transmission of the agents from extrahuman sources to man. Preventive provisions leading to a reduction of the risk of the disease in humans must be specific with regard to different urban cycles.

Growth and bone maturation in children from two regions of the F.R.G. differing in the degree of air pollution: results of the 1974 and 1984 surveys.

Growth and bone maturation criteria were used in this collaborative study to assess the potential health risk posed by excessive air pollutant emission. The study consisted of two surveys carried out 10 years apart. During this decade, a substantial emission reduction through the effective control efforts was achieved in the index area, but not so in the reference area where the situation remained virtually unchanged during this period. In terms of body height and height-weight proportionality, no significant differences were found between areas and years of investigation. In contrast, the bone age retardation encountered in the children from the polluted area was statistically significant, both at 1974 and 1984 surveys, despite the appreciable improvement in this developmental criterion for boys in 1984. This was true for both group mean values and the percentages of individuals exhibiting the bone maturation delay greater than 10 months.

Some ecological criteria of natural focality of mycotic zoonoses.

Mycotic zoonoses sensu stricto and mycotic infections acquired from animal polluted environment belong to diseases characterized by the phenomenon of natural focality. On a global scale they comprise 16 different diseases caused by yeast-like organisms, dematophytes, dimorphous agents of systemic mycoses and primarily saprophytic fungi as well. Prevalence of mentioned diseases is influenced by a number of factors concerning not only biology and ecology of pathogenic agents and particular hosts, but also character of specific extra-animal substrates which make possible long-term maintenance or active propagation of agents in the environment. On the basis of their experience and published data as well, the authors present a survey and analysis of these factors, with particular emphasis on very frequent dermatophytozoonoses and some systemic mycoses. They pay attention to different conditions in urbanized and rural areas and to specific situations encountered by man and food producing animals in these areas. They note different ways of heterotrophy of particular agents and their association with vertebrate hosts which they divide into six ecologically different groups. The authors also characterize the environment in which a portion of saproparatrophic circulation of the agent takes place. They also give a survey of animal-connected human mycoses, which may arise due to occupational hazards.

Animals, parasites and zoonoses in different types of urban areas.

The paper gives a survey of health risks associated with the occurrence of animals in urbanized areas. The author distinguishes the following animal categories involved: I. food-producing animals; 2. pets; 3. synanthropic mammals; 4. synanthropic birds; 5. wild mammals and birds; 6. synanthropic arthropods. From the aspect of animal occurrence and zoonoses or other diseases associated with animals he proposes the following classification of urban areas: a) centre of town, b) pericentral part of town, c) residential areas, d) peripheral part of town, e) suburban recreation areas.

Isolation of Bhanja virus from ticks of the genus Haemaphysalis in southeast Bulgaria and presence of antibodies in pastured sheep.

Bhanja virus was isolated from ticks of the genus Haemaphysalis (H. punctata and H. sulcata) collected from sheep pastured in the surroundings of Akhtopol in southeast Bulgaria, and simultaneously blood sera of 58 sheep were investigated in plaque-reduction neutralization test with B lranja arbovirus. All sera contained antibodies to this virus in titres from 1:32 to 1:4096 (geometrical mean titre 1:494). The district of Akhtopol proved to be a natural focus of Bhanja virus.

Health risks associated with animals in different types of urban areas: present status and new ecological conditions due to urbanization.

For different reasons urban areas are colonized by numerous animal groups. From the aspect of the incidence of zoonoses the following animal groups are primarily significant: 1) food-producing animals; 2) pets; 3) synanthropic mammals; 4) synanthropic birds; 5) synanthropic arthropods. Certain species live in central parts of urban areas which the A. attempts to classify, and particularly in suburban areas which serve for recreation of town inhabitants. From the aspect of the occurrence of different animal species the A. points out the significance of various parts of urban agglomerations.
