| e-test antibiotics susceptibility of strict anaerobic bacteria. | the e-test is convenient for testing susceptibility of anaerobes. from september 1998 to september 1999, 194 strains (105 gram-positive bacteria, 89 gram-negative bacteria) of clinically relevant samples were tested against five antibiotics benzylpenicillin, amoxicillin-clavulanic acid, clindamycin, metronidazole and imipenem on blood agar plates. resistance to benzyl penicillin is widespread and gram-negative bacteria and resistance to amoxicillin-clavulanic acid is exceptional. metronidazole i ... | 2003 | 16887712 |
| anaerobic bacteria cultured from the tongue dorsum of subjects with oral malodor. | the bacteria on the dorsum of the tongue are the most frequent cause of oral malodor; however, the bacterial flora of the tongue has not been well defined. although recent studies have used dna probes to detect the presence of certain periodontal pathogens, cultural studies have been limited because of the complexity of the flora of the tongue dorsum. the purpose of this study was to grow and to identify maximum numbers of capnophylic gram-negative bacilli and anaerobic micro-organisms by cultur ... | 2003 | 16887710 |
| antibiotic susceptibility of clinically relevant anaerobes in estonia from 1999 to 2001. | at present little or no data is available regarding the resistance profiles of anaerobic bacteria in relation to the general usage of antibiotics. the objective of this study was to assess whether any potential relationship exists between the dynamics of antibiotic resistance of anaerobic bacteria and the consumption of antibiotics during the last 3 years within the estonian population. in total, 416 anaerobic isolates were investigated from various clinical samples. the anaerobes were isolated ... | 2003 | 16887688 |
| an in vitro time-kill assessment of linezolid and anaerobic bacteria. | linezolid is a novel oxazolidinone antibacterial agent active against staphylococci (including methicillin-resistant strains), enterococci (including vancomycin-resistant strains), streptococci (including penicillin-intermediate and -resistant streptococcus pneumoniae), and other aerobic and facultative bacteria. the agent has also demonstrated activity against a broad spectrum of gram-positive and gram-negative anaerobic bacteria. previous time-kill assessments have shown linezolid to be genera ... | 2003 | 16887680 |
| taxonomy--general comments and update on taxonomy of clostridia and anaerobic cocci. | since such things as sites of normal carriage, type and severity of infections produced, and antimicrobial susceptibility patterns may vary according to the particular species involved, accurate taxonomy for differentiation of species is important. for example, reclassification of the 'bacteroides gracilis group' revealed that sutterella wadsworthensis is actually responsible for the antimicrobial resistance seen in that group. with clostridia and anaerobic cocci, as with other taxa, there have ... | 2002 | 16887670 |
| peptostreptococcus ivorii-associated skin abscess in a hiv-infected patient. | peptostreptococcus ivorii, a recently described species of gram-positive anaerobic coccus, has so far rarely been found in human infections. the isolation of this anaerobe from a polybacterial skin abscess in a hiv-infected patient, which formed after antiretroviral therapy had been discontinued is reported. local treatment led to the abscess healing without specific antibiotics. as the type strain was isolated from a mixed infected leg ulcer, peptostreptococcus ivorii could play an important ro ... | 1999 | 16887655 |
| in vitro activity of linezolid and eperezolid, two novel oxazolidinone antimicrobial agents, against anaerobic bacteria. | linezolid (formerly u-100766) and eperezolid (formerly u-100592) are novel oxazolidinone antimicrobial agents that are active against multi-drug-resistant staphylococci, streptococci, enterococci, corynebacteria, and mycobacteria. preliminary studies also demonstrated that the compounds inhibited some test strains of anaerobic bacteria. therefore, we extended the in vitro evaluation of these agents to include a total of 54 different anaerobic species. minimal inhibitory concentration (mic) value ... | 1997 | 16887605 |

| anaerobes isolated from clinical material over three years. | data on anaerobic bacteria isolated from clinical specimens at the bacteriology department within the 3-year period (1992-1994) were analysed. anaerobic cultivation was carried out in all aspirates and swabs were transferred in transport media in syringes or blood cultures. established growth occurred in all samples cultivated in thioglycollate broth after 4 days of incubation. cultivation methods included enrichment media, gaspak jar, and api (biomerieux) for final identification. a sulfite-red ... | 1997 | 16887566 |
| peptostreptococcus vaginalis or peptostreptococcus prevotii? identification and clinical importance of a new species of peptostreptococcus. | peptostreptococcus vaginalis is a recently described species of gram-positive anaerobic coccus. we report one case in which p. vaginalis was isolated in pure culture from an abscess on the upper arm, and summarise nine further cases where it was isolated in mixed culture from other superficial sites, particularly infected leg ulcers. we suggest that clinical strains of p. vaginalis have probably been described in the past as peptostreptococcus prevotii, a species which has frequently been report ... | 1997 | 16887558 |
| the aerobic and anaerobic microbiology of pustular acne lesions. | specimens from 32 pustular acne lesions that were inoculated on media supportive for the growth of aerobic and anaerobic bacteria showed bacterial growth. only aerobic or facultative bacteria were recovered in 15 (47%) specimens, only anaerobic bacteria in 11 (34%) specimens, and mixed aerobic and anaerobic bacteria in 6 (18%) specimens. a total of 57 isolates, 31 anaerobes (1.0 per specimen) and 26 aerobes (0.8 per specimen) were recovered. the predominant isolates were staphylococcus sp.

| [in vitro antimicrobial susceptibility of anaerobic bacteria isolated from pleuropulmonary infections]. | aspirative pleuropulmonary infections are usually caused by anaerobic flora of the mouth, mainly prevotella, fusobacterium and peptostreptococcus spp. penicillin in high doses is the traditional treatment for this type of infections but the rising resistance developed in recent years has induced the empiric use of clindamycin, increasing treatment costs. | 2006 | 16758082 |
| lethal outcome in xanthogranulomatous endometritis. | xanthogranulomatous inflammation is rare, mainly involving the kidneys, while primary xanthogranulomatous endometritis (xe) is a very unusual finding, histologically characterized by partial or complete replacement of the mucosa by granulation tissue with an abundance of foamy histiocytes, siderophages and multinucleated giant cells. we present the case of a 69-year-old woman with a short history of abdominal pain and a palpable mass in the pouch of douglas. dilatation of the cervix drained a py ... | 2006 | 16725016 |
| the role of anaerobic bacteria in sinusitis. | the normal oropharyngeal flora contained aerobic and anaerobic bacteria that can cause respiratory infections including sinusitis. some of these bacteria can interfere with the growth of potential pathogens and may play a role in preventing infections. anaerobic bacteria emerge as pathogens as the infection becomes chronic. this may be the result of the selective pressure of antimicrobial agents that enable resistant anaerobic organisms to survive, and from the development over time of condition ... | 2006 | 16701606 |
