In many cases have been caused by Abeta-hemlytic streptococci (Streptococcus pyogenes)‚ and many different bacterial genera and species‚ either alone or together (polimicrobial) can cause this disease. Also in some cases mycotic (fungal) species causes necrotizing fasciitis. In the 1840 to 1870 this condition was described

considered under control with antibiotics‚ have invaded our hospitals and headlines with a vengeance. The vengeance used against us is caused by an existing organism called necrotizing fasciitis‚ the so-called flesh-eating bacteria‚ caused by Group A streptococcus. What this organism does is progressively destroy the human body tissue all the way to the bone. This organism has amazingly outsmarted us of even our most potent drugs. In our community right now‚ medical researchers are testing antibiotics

The total count varied from 1.2x102 to 6.3x103 cfu/ml. Different bacterial genera including Alcaligenes spp.‚ Bacillus spp.‚ Corynebacterium spp.‚ Escherichia spp.‚ Micrococcus spp.‚ Pseudomonas spp.‚ Shigella spp.‚ Staphylococcus spp. and Streptococcus spp. were isolated from the collected samples. The bacterial community was found to be diversified where the concentration of tannery waste was less; thereby it was assumed that the tannery waste might affect the aquatic bacterial community

family of bacteria in the division firmicutes (meaning strong skin and referring to the cell wall) and the class bacilli (which refers to its rod like shape). They look just like streptococcus bacteria from physical characteristics alone. In fact‚ members of the genus Enterococcus were classified as Group D Streptococcus until 1984 when genomic DNA analysis showed that a separate genus classification would be appropriate. Enterococci are part of the normal intestinal flora (good bacteria) of humans
