During the last years, the incidence of respiratory pathology in pig farming has sharply increased. It is acknowledged that their etiology is frequently multifactorial. Together with viruses and mycoplasmae, a number of bacterial species were also shown to be involved. This is essential with regard to rational therapeutic control. The in vitro behaviour of bacterial isolates to antimicrobials is therefore particularly important. The present study was performed in 2005-2008 on the11th pig farms. A total of 191 lung samples from different categories of pigs were investigated. The bacterial findings were positive in 139 or 72.8% of cases. In 84.2% of them, only one microbial species was involved whereas in 15.8% - more than one. In general, 16 bacterial varieties belonging to 13 different taxonomic categories were isolated and identified. The in vitro sensitivity of microbial isolates was the highest against macrolides and florphenicol.
