| [the effect of an unfavorable epizootic situation on the basic epidemiological indices for tuberculosis]. | analysis is given of the basis of epidemiological parameters in two districts of the novosibirsk region, depending on the duration of the unfavourable epizootic situation. subjects with extensive residual changes were registered 10 times as often in the district with the unfavourable epizootic situation as in the district with fresh tuberculosis outbreak in animals. studies of infectivity among children and adolescents at the height of tuberculosis outbreak in animals showed that reversion was e ... | 1992 | 1289876 |
| [genetic problems of cattle resistance to brucellosis. i. the age of having the disease, the paternal influence and strain affiliation in the incidence of brucellosis morbidity]. | from 2810 animals of black-and-white breed of novosibirsk region diagnosed, 31% fell ill. young animals were found to be more resistant to brucellosis. it is evidently more probable that they can reach the reproductive age. intrapopulation hereditary heterogeneity to brucellosis was found. the progeny of certain bulls has a higher resistance than others. there is no statistical reliability of differences in the frequency of the disease between animal lines. a normal distribution of fathers accor ... | 1981 | 7195859 |
| [dynamics of major constituents of tuberculosis morbidity in the population of novosibirsk region]. | after processing the dynamic series of tuberculosis morbidity in the population of the novosibirsk region by the smooth component methods, two major constituents were defined in morbidity dynamics. in total, they make up about half the total variability of tuberculosis morbidity. the first constituent is due to socioeconomic causes that are common for the whole region. the second one shows rather evident 10-year fluctuations. the same 10-year fluctuations are observed in the dynamics of tubercul ... | 2000 | 10838897 |
