Proširenost nematoda Capillaria hepatica u smeđeg štakora (Rattus norvegicus) u Hrvatskoj.

An analytical cross-sectional study of Capillaria hepatica in 307 Norway (brown) rats (Rattus norvegicus) was performed. Rats were trapped in two rural regions in Croatia. The prevalence of adult C. hepatica was 1.95%. The parasite was observed in 6 rats. Of these, 3 out of 189 (1.59%) were male and 3 out of 118 (2.54%) female. The adult parasite was a more common finding in large rats and was observed in 5 (1.95%) large rats and in one (2.17%) intermediate rat. Adult C. hepatica was not found among 4 examined young rats. Positive rats were derived from only four households. Clustering of adult parasites found among examined 17 households was significant (P<0.001). Eggs of C. hepatica were found in 12 (3.91%) rats. The majority of positive rats with adult C. hepatica had parasite eggs (P<0.001) and having adult parasite in livers, increases of 210 × odds of having parasite eggs in intestines (OR=210, P<0.001).Pretraženo je 307 smeđih štakora (Rattus norvegicus), podrijetlom iz dvije županije u Hrvatskoj, na prisutnost nematoda Capillaria hepatica. Proširenost adulta C. hepatica bila je 1,95%. Parazit je nađen u šest štakora, i to u tri od 189 mužjaka (1,59%) i tri od 118 ženki (2,54%). Adulti C. hepatica su nađeni češće u velikih štakora i to u 5 (1,95%), i u 1 (2,17%) štakora srednje veličine, dok u mladih štakora adulti C. hepatica nisu nađeni. Pozitivni štakori su potjecali iz samo 4 dvorišta. Nađeno grupiranje odraslih parazita među 17 dvorišta bilo je značajno (P<0,001). Jajašca C. hepatica nađena su u 12 (3,91%) štakora. Većina pozitivnih štakora s adultima C. hepatica imali su i parazitska jajašca (P
