EFFECT OF SOW SKIN DISINFECTION ON ENTEROBACTERIACEAE COUNTS WITH EMPHASIS ON ESCHERICHIA COLI

The aim of the present study was to investigate the impact of sow skin disinfection in commercial breeding conditions on Enterobacteriaceae and Escherichia coli counts. The study included 30 sows from a pig-breeding farm. The ventral part of the sow trunk with mammary glands was disinfected before placing the piglets under the sow. Skin swabs were obtained by use of cellulose sponge and quantitatively analyzed according to the ISO 21528-2:2004 and ISO 16649-2:2001 standard methods. The mean Enterobacteriaceae and Escherichia coli counts were significantly lower after disinfection (P<0.001), resulting in 98.4% and 98.8% reduction, respectively.
Cilj ovog rada bio je istražiti utjecaj dezinfekcije kože krmača držanih u komercijalnim uzgojnim uvjetima na broj bakterija porodice Enterobacteriaceae i vrste Escherichia coli. Istraživanjem je bilo obuhvaćeno 30 krmača na svinjogojskoj farmi. Ventralni dio trupa krmača, s mliječnim žlijezdama, dezinficiran je neposredno prije stavljanja prasadi pod krmače. Obrisci površine kože dobiveni su korištenjem celuloznih spužvica i kvantitativno analizirani prema standardnim metodama ISO 21528-2:2004 i ISO 16649-2:2001. Prosječni broj enterobakterija i bakterija Escherichia coli bio je značajno manji nakon dezinfekcije (p<0,001), koja je rezultirala smanjenjem broja bakterija za 98,4%, odnosno 98,8%.
