Prevalencija bakterije Francisella tularensis u populaciji sitnih sisavaca u kontinentalnim šumama Hrvatske

Francisella tularensisis is a causative agent of tularemia a zoonotic disease that infects wide range of hosts including arthropods, mammals and birds.

Description
Summary:Francisella tularensisis is a causative agent of tularemia a zoonotic disease that infects wide range of hosts including arthropods, mammals and birds. In this study, the prevalence of tularemia among small mammals in Croatia was investigated. The 444 samples of small rodents and insectivores were collected in eight different localities in continental Croatia during the 2-year study. Spleen samples of: 197 Apodemus agrarius (striped field mouse), 78 Apodemus sylvaticus (wood mouse), 92 Apodemus flavicollis (yellow-necked mouse), 17 Myodes glareolus (bank vole), 27 Mycrotus agrestis (field vole), 20 Microtus arvalis (common vole) and 13 Sorex araneus (common shrew) were investigated for the presence of DNA of Francisella spp. using qRT-PCR method. Two striped field mouses and one wood mouse, originated from the same area - locality of Lipovljani, were found to be positive on Francisella spp. revealing the presence of bacteria among small mammals population in Croatia. Francisella tularensisis uzročnik je zoonoze tularemije, koja ima široki raspon domaćina, uključujući člankonošce, sisavce i ptice. Dvije podvrste F. tularensis, subsp. tularensis (Tip A) i subsp. holartica (Tip B), opisane su kao najčešći uzročnici bolesti u ljudi (Kingry and Petersen, 2014; Kuehn et al., 2013). Tip A i Tip B razlikuju se po svojim biokemijskim značajkama, patogenosti, ekologiji, epidemiologiji te geografskoj rasprostranjenosti. Rasprostranjenost Tipa A uglavnom je ograničena na sjevernoamerički kontinent, za razliku od Tipa B, koji se javlja duž cijele sjeverne polutke, a ujedno je i najčešći uzročnik tularemije u Europi(Keim et al., 2007; Kuehn et al., 2013). No ekologija i kruženje ove bakterije u prirodi do danas još nisu u potpunosti razjašnjeni. Različiti glodavci (voluharice, miševi, tekunice, bizantski štakori, dabrovi) te dvojezupci (kunić i zec) opisani su kao mogući rezervoari F.tularensis. Zadnja epidemiološka i epizootiološka istraživanja tularemije u Hrvatskoj datiraju iz šezdesetih i sedamdesetih godina prošloga ...
