Abstract:

In this study, the resistance of swine Staphylococcus isolated in summer and winter was compared. The rectal anal swab samples and nasal swab samples were collected from the same pig in summer and winter. The susceptibility test of 9 kinds of antimicrobial drugs was carried out by using the broth dilution method. The results revealed that the resistance rates of Staphylococcus isolated from the rectum in summer were higher than that of Staphylococcus isolated from the rectum in winter to amikacin, florfenicol, levofloxacin, benzene and clindamycin. Resistance rates of Staphylococcus isolates from nasal cavity in summer were lower than that of Staphylococcus isolates from nasal cavity in winter to amikacin, benzene, gentamicin, levofloxacin, tetracycline, clindamycin and rifampicin. And Staphylococcus in two seasons in 0 to 9 resistant rectal separation resistance were distributed. Multi drug resistant Staphylococcus in two seasons in 1 to 9 resistant rectal separation resistance were distributed. And in the 6 resistance, the resistance rate of Staphylococcus isolated from the nasal in summer was significantly higher than that of the isolated from anal in winter (P< 0.05). And in 8 resistance, the resistance rate of Staphylococcus isolated from the rectum cavity in summer was significantly higher than that of Staphylococcus isolated from the rectum cavity in winter (P< 0.05). Results showed that the resistance rates of Staphylococcus isolated from different sites of the pigs to the tested antimicrobial drugs were different. The drug resistance rate was correlated with seasonal use of the farm.
