Епізоотологічна ситуація щодо вісцеральних мікозів тварин в умовах Центрального регіону України

Abstract

У статті надано результати мікологічних досліджень патологічного матеріалу, відібраного від загиблої птиці та домашніх тварин в умовах Центрального регіону України (Полтавська область). Мікобіота, виділена із досліджуваних зразків, була представлена грибами роду Aspergillus, Mucor, Candida у вигляді моноінфекції та в асоціації. Найчастіше виділяли гриби роду Aspergillus та Mucor. Із всіх збудників мукормікозу найчастіше ідентифікували гриби роду Mucor, а саме – вид Mucorramosissimus.

В статье предоставлены результаты микологических исследований патологического материала, отобранного от погибшей птицы и домашних животных в условиях Центрального региона Украины (Полтавская область). Микобиота, выделенная из исследуемых образцов, была представлена грибами рода Aspergillus, Mucor, Candida в виде моноинфекции и в ассоциации. Чаще всего выделяли грибы родаAspergillus и Mucor. Из всех возбудителей мукормикоза чаще всего идентифицировали грибы рода Mucor, а именно – вид Mucorramosissimus.

The article presents the results of mycological and toxicological researches of pathological material taken from poultry and domestic animals in Central region of Ukraine (Poltava region). Mycobiota isolated from the samples was represented by fungi of genuses Aspergillus, Mucor, Candida as monoinfection and in association. The main part of isolated fungi accounted by micromycetes of genus Aspergillus, they have identified in 28 of 43 samples (65% of all positive researches). In particular, species A. flavus and A. fumigatus isolated more often (40% and 23 positive results, respectively). As a monoinfection fungi of genus Aspergillus isolatedfrom 25 samples (58%). With regard to fungi fromfamily Mucoraceae, theirsgrowthidentifiedfrom 14 samples of pathological material, that is 33% of all positive mycological researches. From 7 samples was isolated the causative agent of mucormycosis only, (16% from all positive researches), from 3 samples – the causative agents of aspergillosis and mucormycosis simultaneously (7% from all positive samples). The fungi of genus Candidа identified from 12% of all positive researches, simultaneously in association with the causative agent of mucormycosis – 1 sample (2%). Also in single samples detected fungi of genus Penicillium and Helmintosporium in association with micromycetes of family Mucoraceae. To each association accounted to 2% of all positive results of corpses mycological research. Of all causative agents of mucormycosis the most often identified fungi of the genus Mucor - in 7 lung samples from poultry(16% of all positive results). These include fungi species of Mucor ramosissimus, M. racemosus, M. pusillus. Fungi of genus Rhizomucor, Rhizomucor pusillus in particular allocated with 3 samples (7% of all positive results). Most rarely of fungi from family Mucoraceae detected fungi of genus Rhizopus, species Rhizopus microsporus - in 2 samples, that is 5% from all positive researches. The independent allocation isolates fungi from family Mucoraceae of pathological material at negative results of bacteriological researches gives reason toconsidered the mucormycosisas a cause of death of studied birds and animals. The results showed, that most often fungi from family Mucoraceae isolated in association with aspergills and less often with fungi of the genus Candida. That confirms the possibility of associated course of mucormycosis with aspergillosis or candidosis.
