An experimental model of pseudotuberculosis infection was developed using Papio hamadryas monkeys. Clinical manifestations and some microbiological and immunological aspects of pseudotuberculosis caused by oral infection of animals are studied. The values of LDs0 of the pseudotuberculosis agent are established for monkeys, white mice, and guinea pigs. Oral infection of monkeys with sublethal doses of Yersinia pseudotuberculosis is found to induce a pronounced specific immunity. The efficacy of immunoblotting for serologic diagnosis of pseudotuberculosis in clinically obscure cases is demonstrated.
Оценена зависимость морфологических свойств микробов Yersinia pseudotuberculosis 164/84 от темпера туры культивирования и носительства fra-оперона чумного микроба. При температуре выращивания 4-6 °С бактерий двух изогенных вариантов (fra+ и fra) штамма 164/84 отмечается меньшая, по сравнению с темпе ратурой 26-28 и 36-38 °С, скорость развития популяции. Существенные различия между микробами fra+-и fra-вариантов проявляются лишь на поздних сроках выращивания культур при температуре 36-38 °С и заключа ются в относительно больших размерах клеток капсулообразующего варианта. Ключевые слова: Yersinia pseudotuberculosis, микробная культура, fra-оперон, антиген FI, fra+-и fra-изогенные варианты.
Assessed were possibilities of identification and differentiation of glanders and melioidosis etiological agents by means of PCR method using different nucleotide sequences of the pathogenic Burkholderia. Primers perspective for inclusion in the test-system assigned for detection of glangers and melioidosis etiological agents DNA in environmental samples and biological materials were selected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
