Campylobacteriosi nel perugino nel primo biennio del nuovo secolo: alcuni aspetti e considerazioni di microbiologia clinica

794 faecal specimens of outpatients with enteritis during 2001-02 were examined for pathogens. Campylobacter jejuni/coli (14.2%) and Salmonella spp (15.1%) prevailed among bacteria. 3 strains of Arcobacter butzleri were isolated too (0.4%). C. jejuni prevailed (85.7%) in respect of C. coli (11.8%) and A. butzleri (2.5%), as in children as in adults. C. jejuni biotype 1 was prevalent (68.6%) in respect of C. jejuni b. 2 (29.4%) or C. jejuni b. 3 (2.0%); also C. coli b. 1 prevailed (78.6%).The average of infected people was 4 years for children (0-14 years old) and 48 for adults, with a range between 3 moths and 84 years. Regarding patterns of resistance to antibiotics, were observed 6.7% of resistance (R) to erytromycin, 49.5% to norfloxacin (and similar quinolones), 37.8% to tetracycline, 31.1% to minocycline, 1.7% to amoxicyllin + clavulanate, 0.8% to gentamycin and chloramphenicole. No particular correlations were observed between age, sex, clinical findings and species or biotype of isolated Campylobacter. Concluding, the filter membrane technique is preferable for isolating these spirilla, the identification of genus and species could be rational, macrolides are always the first choice molecules for therapy when mandatory.
