Mycobacterium tuberculosis in animal and human populations in six Central European countries during 1990-1999

Abstract

Results of Mycobacterium tuberculosis detection in animals from six Central European countries (Croatia, the Czech Republic, Hungary, Poland, Slovakia and Slovenia) spreading over 610 402 km2 with a population of 11.8 million heads of cattle were analysed. In the monitoring period, 1990 to 1999, M. tuberculosis from animals was isolated only in two countries (Poland and Slovak Republic) from 16 animals with tuberculous lesions. These comprise nine heads of cattle (Bos taurus), four domestic pigs (Sus scrofa f. domestica) and three wild animals, an African elephant (Loxodonta africana), agouti (Dasyprocta aguti) and terrestrial tapir (Tapirus terrestris), originated form a zoological garden Gdansk in Poland. Steady decrease in the incidence of tuberculosis in humans was recorded during the monitoring period in all countries. The human population of the study countries was 68.03 million. In the period monitored, infection caused by M. tuberculosis was identified in a total of 241 040 patients with a decreasing incidence of tuberculosis found in all countries. The lowest relative bacteriologically confirmed disease was found in theCzechRepublic,SlovakRepublic andSlovenia. Given the low number of infected domestic and wild animals, the epidemiological and epizootiological situation may be considered auspicious.
