Enterococcus faecalis is a gram positive‚ commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals [1].E. faecalis can cause life-threatening infections in humans. Moreover‚ the antibiotic resistance exhibited at high levels by E. faecalis contributes to its pathogenicity [2]. Several reports state that enterococcal species possess the property of causing a variety of diseases in humans [3‚ 4]. It is known from previous studies that Enterococcus faecalis can cause endocarditis

Treatment Topical fluoroquinolones alone or in combination with one or two other antibiotics (aminoglycoside‚ cephalosporin) usually suffices for Blebitis type 1 & 2. The patient should be examined daily for the initial 1-2 weeks as there is always a possibility of rupture of the cystic bleb. Topical antibiotics should be continued for a period of 2-3 months and then tapered.

Most commonly‚ Citrobacter freundii lives as a normal occupant in the feces from the intestinal tract of humans and animals (1). C. freundii can also be found in soils‚ water‚ sewage‚ and food (1). Being a facultative anaerobe‚ C. freundii can live in both the absence and presence of oxygen (1). The bacterium’s optimal temperature is 37ᵒC (1). C. frundeii is also a chemoorganotrophic‚ which means that the microorganism requires an organic source of carbon to oxidize chemical bonds from for its
