Ecology and zoonotic potential of nematode Capillaria aerophila Creplin 1839 (Trichurida: Trichinellidae) by red fox (Vulpes vulpes L.) on the terirory of Vojvodina

Abstract

<p>Imajući u vidu opasnost od zoonotske i antropozoonotske transmisije<em> Capillaria aerophila&nbsp;</em>po&nbsp;zdravlje životinja i ljudi, u ovom radu je ispitivana prevalencija kapilarijaze kod lisica&nbsp;poreklom sa različitih lokaliteta područja Vojvodine. Istraživanjem je bilo obuhvaćeno 146&nbsp;le&scaron;eva lisica. Uzorci lisica su prikupljani od decembra meseca 2009. do decembra meseca&nbsp;2012. godine. Sagledavanjem rezultata patolo&scaron;ke sekcije traheja i bronhija pluća 146 lisica,&nbsp;dobijena je izuzetno visoka prevalencija kapilarijaze od 77%, na osnovu čega se može&nbsp;zaključiti, da je područje Vojvodine novo područje u svetu sa izuzetno visokom prevalencom&nbsp;<em>C.</em> <em>aerophila&nbsp;</em>kod crvene lisice. Primenom koprolo&scaron;kog metoda ispitivanja kapilarijaza je&nbsp;dokazana kod 55 (41%) od ukupno 133 ispitivane lisice. Najveći broj lisica pozitivnih na&nbsp;prisustvo <em>C.</em> <em>aerophila&nbsp;</em>je bio iz Južnobačkog (24,7%) i Sremskog okruga (21,2%), a najmanji&nbsp;iz Južnobanatskog okruga (1,4%). Lisice Vojvodine su visoko infestirane kapilaridama.&nbsp;Ukupno je izolovano 1249 jedinki respiratorne nematode <em>C.</em> <em>aerophila</em>. Srednji broj nađenih&nbsp;parazita u traheji je bio 11,0, sa varijacijama od 1 do 60 kod pojedinih lisica. Među&nbsp;kapilaridama dominirale su ženke (67%), visoko reproduktivno sposobne, u odnosu na&nbsp;mužjake (33%). Korelativnom analizom između sezonskih količina padavina u Vojvodini i&nbsp;srednjeg broja nađenih adulta <em>C. aerophila&nbsp;</em>u traheji i bronhijama lisica utvrđeno je postojanje&nbsp;srednje značajne povezanosti. Patohistolo&scaron;kom analizom sluzokože traheja i tkiva pluća kod&nbsp;14 lisica, nisu bile utvrđene značajne patolo&scaron;ke promene. Ni u jednom slučaju nije bilo&nbsp;utvrđeno prisustvo parazitskih elemenata u tkivu pluća, koji bi ukazali na postojanje&nbsp;verminozne pneumonije kod lisica.&nbsp;</p>

<p>Having in mind an animal or human health hazard from zoonotic and anthropozoonotic transmissions of <em>Capillaria aerophila</em>, this paper is investigating a prevalence of capillariasis in foxes from different sites in Vojvodina.<br />Research included 146 fox corpses. Samples were gathered from December 2009 to December 2012. The resulting extremely high prevalence kapilarijaze of 77%, based on the results of pathologicalsections of the trachea and bronchi of the lung in 146 foxes, on the grounds thatit can be concluded that the area of Vojvodina new area in the world with an extremely high prevalence of&nbsp; <em>C. aerophila&nbsp;</em>in red foxes. Coprology proved capillariasis in 55 (41%) out of&nbsp; 133 examined foxes. The majority of positive foxes were from the South Bačka District (24,7%) and Syrmia (21,2%), and the smallest number of positive ones were from South Banat District (1,4%). Foxes in Vojvodina were highly infested with capillary worms. A total of 1249 <em>C. aerophila&nbsp;</em>nematode has been found. Average number of found parasites in trachea was 11,0 with variations from 1 to 60 in somefoxes. Among capillary worms, females prevailed (67%), very reproductivly capable, compared to males (33%). Correlative analysis showed the existence medium significance level of correlation between seasonal precipitation in Vojvodina, and the mean number found nematode <em>C. aerophila</em> in the trachea and bronchi fox. Pathohistology of tracheal mucosa and lung tissue in 14 foxes did not determine significant pathological changes. In neither one of the cases was determined the presence ofparasite elements in lung tissue, which would point to the existance of fox verminous pneumonia.</p>
