[Campylobacter spp. as a leading cause of human bacterial gastroenteritis in selected region of Poland]

Abstract

The results of the epidemiological analysis of campylobacteriosis reported by Regional Laboratory of Sanitary Epidemiological Station in Bielsko-Biala (PSSE Bielsko-Biala), Silesia voivodeship in Poland are presented. From August 2006 to July 2009, stool samples from diarrhea cases were examined for the presence of Campylobacter spp. as well as Salmonella, Shigella, Yersinia, enteropathogenic (EPEC) and verotoxigenic (VTEC) E. coli. The most frequently isolated species of Campylobacter spp. was C. jejuni. Most of the Campylobacter spp. were isolated from children under the age of 2. The seasonal peak of campylobacteriosis was observed between July and December. All isolates of Campylobacter sp. were sensitive to erythromycin and gentamicin. It was observed that 71.4% C. jejuni isolates were resistant to ciprofloxacin. The comparison of the results obtained during the period of 2006-2009 shows that percentage of campylobacteriosis has increased. In the first year of studies (from August 2006 to July 2007), Campylobacter spp. were reported in 45.4% of 183 bacterial etiologic agents of gastroenteritis, isolated from 819 persons; in the second year (August 2007-July 2008) there were 46.6% of 176 bacterial etiologic agents isolated from 844 persons; and in the last year of study (August 2008-July 2009), Campylobacter spp. were reported in 51.5% of 196 bacterial etiologic agents isolated from 859 persons. The percentage of salmonellosis cases decreased by about 20% from 45.4 to 23% during that frametime.
