A Case Of Entamoeba Histolytica Infection Among Men Who Have Sex With Men.

Entamoeba histolytica is a parasite responsible for intestinal amebiasis and possible extraintestinal manifestations, such as liver abscesses. India, Africa, Mexico, and Central and South America have some of the highest rates of infection due to poor socioeconomic and environmental conditions. The infection has become more common in the United States due to an increase in emigration. There has been a rising incidence of sexual transmission of the infection, most commonly seen in men who have sex with men. Here, we present a case of a symptomatic extraintestinal E histolytica infection in a young Hispanic bisexual man.

Community acquired Klebsiella pneumoniae meningitis: a case report.

INTRODUCTION: Klebsiella pneumoniae meningitis is most commonly seen as a nosocomial infection and in post-neurosurgical patients. Reports of community acquired Klebsiella pneumoniae meningitis cases are rare in the United States. The objective of this case report is to discuss an uncommon pathogen causing meningitis, Klebsiella pneumoniae, its risk and prognostic factors and to emphasize the importance of early recognition and appropriate antibiotic treatment. CASE REPORT: We report a clinical case of adult community acquired Klebsiella pneumoniae meningitis with recovery. A 54-year-old diabetic male presented with two-week history of intermittent fevers, acute bilateral ear pain, headache and unsteady gait. Broad spectrum antibiotics were initiated. Klebsiella pneumoniae was isolated in the cerebrospinal fluid cultures. The patient recovered with only mild hearing loss in his left ear. CONCLUSION: Our case highlights the importance of suspecting Klebsiella pneumoniae in community acquired meningitis.

A Rare Case of Pneumonia Caused by Shewanella putrefaciens.

Shewanella putrefaciens is a gram-negative, nonfermentative, oxidase positive, motile bacillus that produces hydrogen sulphide. It is found widely in the nature especially in marine environments. In some very rare cases Shewanella putrefaciens can be a human pathogen. It can produce a wide variety of clinical syndromes including bacteremia as well as skin and soft tissue infections. However, pneumonia due to S. putrefaciens is rare; there are a total of 4 reported cases in the literature. We present a case of 63-year-old male who was presented to emergency room status after cardiac arrest, fell into sea water face down. On the second day of hospitalization, he was diagnosed to have pneumonia based on the clinical, radiological, and laboratory findings. Empirical antibiotic treatment with vancomycin and piperacillin/tazobactam combination was initiated. Gram-stained smear of endotracheal aspirate yielded gram-negative bacteria, and the isolate grown from endotracheal aspirate culture was identified as S. putrefaciens by Biomerieux API 20 NE technique. On review of the literature and according to culture and sensitivity results, therapy in our patient was changed to cefepime. Patient's pneumonia improved with treatment with cefepime. We believe that our patient developed pneumonia evidently caused by S. putrefaciens, after near drowning in sea water. The pneumonia resolved after treatment with cefepime.
