    I – GENERAL CHARACTERISTICS: A – Definition: Gram-negative bacilli, by a polar mobile ciliature rarely still, non-spore forming. Chemo-organotrophic bacteria with a strictly respiratory metabolism with terminal electron acceptor such as oxygen aerobically and for some species anaerobically with nitrate synthesis of nitrate reductase (“breathing nitrates”). Oxidative or inactive in the trial of Hugh and…

    I – Physiology: Strictly anaerobic bacteria are bacteria hypersensitive to the action of oxygen (anoxybiontiques). They produce their energy and perform their biosynthetic reactions in the absence of the electron acceptor. Most (exceptions) do not have the conventional enzyme respiratory systems called: cytochromes, catalase, peroxidase. They produce energy during fermentation processes. These bacteria do not…

    General Bacteroidaceae family consists of various kinds of bacilli Gram-negative obligately anaerobic Bacteroides, Porphyromonas, Prevotella, Fusobacterium, Wolinella, Leptotrichia, Butyrivibrio, Succinivibrio, Succinimonas, Anaerovibrio, Anaerobiospirillum, Mobiluncus, Selenomonas, Pectinatus, Acetivibrio, Lachnospira. These bacteria are part of the oral flora, flora of the upper respiratory tract, intestinal and urogenital tract. The genera Bacteroides, Prevotella and Porphyromas are most important…

    OTHER BACTERIA BITES: Bacteria cited herein are present in the oral flora of animals and can be found in wounds or when consecutive septicemia bites. These are small Gram-negative bacilli, motionless, giving small colonies that grow slowly on blood agar or chocolate agar incubated in an atmosphere enriched in CO ^. Not yet classified accurately,…

    Actinomycetes are in the order of Actinomycetales. Some representatives of the actinomycetes, especially among aerobic, have long been rejected by all the bacteria and fungi mistaken because of their morphology, sometimes fungoides. This is a suprageneric group, bringing together diverse bacteria dispersed in systematics, where one brings Nocardia genera Actinomyces, Mycobacterium, Corynebacterium, Streptomyces actinomycetesBifidobacterium ……
