The cases of 4 children who developed postthoracotomy sternal wound infection caused by anaerobic bacteria are presented. The predominate anaerobes were Peptostreptococcus species and pigmented Prevotella species. Polymicrobial infection was present in all cases, and aerobic bacteria also were recovered in 2 instances. All patients responded to surgical debridement and antimicrobials effective ...

background. the most common species isolated from primary endodontic infections are black-pigmented bacteria. these species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature. therefore, the present study was carried out to evaluate the presence and identification of various pigmented porphyromonas and prevotella species in the infected roo...

Bacteria phenotypically resembling members of the phylogenetically distinct planctomycete group of the domain Bacteria were isolated from postlarvae of the giant tiger prawn, Penaeus monodon. A selective medium designed in the light of planctomycete antibiotic resistance characteristics was used for this isolation. Planctomycetes were isolated from both healthy and monodon baculovirus-infected ...

Black-pigmented bacteria are one of the neglected species to cause periodontal disease in cats, and they also zoonotic agents that pose an infection risk humans. In this study, we aimed determine presence Porphyromonas gingivalis, gulae Prevotella nigrescens oral microbiota pet stray cats. Dental swab samples were taken from 25 cats with symptoms then investigated by multiplex polymeras...

Bacteria from the phylum Deinococcus-Thermus are known for their resistance to extreme stresses including radiation, oxidation, desiccation and high temperature. Cultured Deinococcus-Thermus bacteria are usually red or yellow pigmented because of their ability to synthesize carotenoids. Unique carotenoids found in these bacteria include deinoxanthin from Deinococcus radiodurans and thermozeaxan...
