“…. Moreover, these two species are found in pigs suffering from pneumonia (Under-The main bacterial pathogens in respiratory dahl et Kobisch & Tillon, 1985; disease in pigs are Pmteurella multocida, Borde- Morrison et al, 1985). In swine, Haemophilus tella bronchiseptica, and Haemophilus pleuropneu-pleuropneumoniae is a respiratory pathogen monzae.…”

The minimal inhibitory concentrations (MIC) of five tetracyclines and ten other antimicrobial agents were determined for four porcine bacterial respiratory tract pathogens by the agar dilution method. For the following oxytetracycline-susceptible strains, the MIC50 ranges of the tetracyclines were: P. multocida (n = 17) 0.25-0.5 micrograms/ml; B. bronchiseptica (n = 20) 0.25-1.0 micrograms/ml; H. pleuropneumoniae (n = 20) 0.25-0.5 micrograms/ml; S. suis Type 2 (n = 20) 0.06-0.25 micrograms/ml. For 19 oxytetracycline-resistant P. multocida strains the MIC50 of the tetracyclines varied from 64 micrograms/ml for oxytetracycline to 0.5 micrograms/ml for minocycline. Strikingly, minocycline showed no cross-resistance with oxytetracycline, tetracycline, chlortetracycline and doxycycline in P. multocida and in H. pleuropneumoniae. Moreover, in susceptible strains minocycline showed the highest in vitro activity followed by doxycycline. Low MIC50 values were observed for chloramphenicol, ampicillin, flumequine, ofloxacin and ciprofloxacin against P. multocida and H. pleuropneumoniae. B. bronchiseptica was moderately susceptible or resistant to these compounds. As expected tiamulin, lincomycin, tylosin and spiramycin were not active against H. pleuropneumoniae. Except for flumequine, the MIC50 values of nine antimicrobial agents were low for S. suis Type 2. Six strains of this species showed resistance to the macrolides and lincomycin.

“…Streptococcus suk Type 2 is frequently isolated from diseased pigs with pneumonia. It is therefore considered to be a possible cause of pneumonia in swine (Kochne et al, 1979;Kobisch & Tillon, 1985;Vecht et al, 1985).…”

Summary An investigation on the occurrence of different pneumonia types and their possible concurrence with other pluck organ disorders was made on 6,565 pigs presented at slaughter. The frequency of disseminated focal nephritis in a bronchopneumonia group and a non‐bronchopneumonia residual group, respectively, was found to differ significantly from the mean frequency of nephritis in all pig plucks examined. The number of lesioned kidneys in each of 28 samples contributing to the bronchopneumonia group and in each of 8 samples contributing to the residual group was regressed group‐wise on the number of individual plucks examined in each sample; the correlation coefficient for each of these two groups was calculated. These calculations showed a highly significant link between bronchopneumonia and disseminated focal nephritis. The histopathological and bacteriological examination of some lung and kidney lesions representing the bronchopneumonia group substantiated this finding. It is concluded that the two diseases are connected through dissemination, and that Pasteurella multocida is the organism involved in the majority of cases.
