according to changes in the surface of respiratory epithelial cells and host immunity as well as virulence of hospital acquired pathogens, oropharyngeal colonization enhance in hospital admitted patients. patient admission in hospital, due to changes of oropharyngeal flora and colonization of virulent germs such as staphylococcus aureus and gram negative bacilli can be a serious problem for dev...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.

Capnocytophaga organisms are capnophilic, gram-negative bacilli that have been associated with infections deriving from the flora of the oropharynx. We report a case of inguinal adenitis caused by Capnocytophaga species that probably represents sexual transmission of the pathogen.

Acinetobacter lwoffii, a nonfermentative gram-negative aerobic bacillus, which presents in the normal flora of the oropharynx and skin, has recently been reported as a cause of human infection. Herein, the authors present a case report of peritonitis related to automated peritoneal dialysis caused by A. lwoffii.

Although Neisseria species other than N gonorrhoeae and N meningitidis normally comprise part of the commensal bacterial flora of the oropharynx, they may occasionally act as opportunistic pathogens. Infections in which these organisms have been implicated include cases of endocarditis, meningitis, septicaemia, otitis, bronchopneumonia and possibly genital tract disease. In this paper, the clin...

CONTEXT The oropharynx microbiota plays an important role in the origin of infections, especially among alcoholics whose airway defenses are impaired. OBJECTIVE To compare the normal oropharingeal flora in heavy alcohol drinker and non-alcoholics. PATIENTS 117 persons, 58 heavy alcohol drinkers and 59 non-alcoholics. SETTING Santa Casa de São Paulo Emergency Service. DESIGN A blind pros...

Surgically placed shunts have proven useful in diverting excess accumulation of cerebrospinal fluid. The properly functioning shunt prevents increased intracranial pressure, gross craniofacial distortion, and the development of mental retardation, all of which have always been associated with the untreated hydrocephalic patient. The postoperative complication of microbial colonization of shunts...

The pharmacokinetics of ciprofloxacin and its effect on the oropharyngeal bacterial flora were examined in 21 ill patients being treated for methicillin-resistant Staphylococcus aureus infections or colonization or both. Oral ciprofloxacin (750 mg twice a day) produced peak and trough concentrations in serum of 2.56 +/- 1.80 and 0.97 +/- 0.81 micrograms/ml and steady-state salivary and nasal se...

AIM To assess the safety and cost effectiveness of a usage for seven days of breathing circuit systems (BCSs) in combination with heat moisture exchanger filters (HMEF) in operation room anesthesia. METHOD In a prospective longitudinal clinical study, the contamination on high-risk surfaces (HMEF together with inner and outer surface of BCS) was monitored over 1, 2, 5, and 7 days. RESULTS of ...

Background: Brain abscesses are intracerebral infections with pus accumulation that can be fatal in most cases without appropriate treatment. The common cause of brain streptococci and staphylococci. Streptococcus anginosus is a group part the normal flora oropharynx rarely severe bacterial infections. Case Report: Our patient 64-year-old man who underwent dental procedure, presented few days l...
