Heat shock proteins in bacilli.

Five strains of bacilli, including a nonsporulating strain, when heat shocked, accelerated the synthesis of a specific subset of proteins. The major heat shock protein in all bacilli had a molecular weight of 66,000. The response persisted for at least 40 min and could be eliminated upon a shift down to 37 degrees C.     

Potential virulence factors of Proteus bacilli.

The object of this review is the genus Proteus, which contains bacteria considered now to belong to the opportunistic pathogens. Widely distributed in nature (in soil, water, and sewage), Proteus species play a significant ecological role. When present in the niches of higher macroorganisms, these species are able to evoke pathological events in different regions of the human body. The invaders (Proteus mirabilis, P. vulgaris, and P. penneri) have numerous factors including fimbriae, flagella, outer membrane proteins, lipopolysaccharide, capsule antigen, urease, immunoglobulin A proteases, hemolysins, amino acid deaminases, and, finally, the most characteristic attribute of Proteus, swarming growth, enabling them to colonize and survive in higher organisms. All these features and factors are described and commented on in detail. The questions important for future investigation of these facultatively pathogenic microorganisms are also discussed.     

Sporulation of bacilli

В ходе формирования спор о Bacillus мегатерий, цистеина и cystine содержанием белков увеличивается. Способность клеток к включению³⁵S цистеина заметно, поднятые в ходе формирование спор. Белки спор из Bacillus мегатерий содержат в пять раз насколько cystine плюс цистеина в вегетативной клетки до формирования спор. Possibillity что некоторые из цистеина и cystine могут быть синтезированы из метионина в ходе формирования спор, и возможной роли в их cystine белка Структура обсуждается.
