an immunosuppressed man was admitted to hospital with diarrhea and a history of urinary tract infection. he was subjected to treatment with antibiotics. the patient died of putative severe sepsis. the etiological agent was a carbapenemase producing isolate of bacillus circulans with resistance to all prescribed antimicrobial agents.

background: cryptosporidium and isospora are known as one of the main cause of diarrhea in both immunocompetent and immunocompromised subjects, all over the world. incidence of enteropathogens such as cryptosporidium spp. and isospora belli considerably has increased, since immunodeficiency virus (hiv) rapidly disseminated. in addition, cancer patients are highly susceptible to opportunistic in...

conclusions it is concluded that cryptosporidium spp. should be considered in immunocompromised diarrheal patients and elisa must be chosen for detection of this parasite. modified acid fast staining and cassette kit techniques could be performed if elisa is not available. the single use of the cassette kit will be inadequate for the diagnosis of cryptosporidiosis. background cryptosporidiosis ...

invasive gastric mucormycosis is a rare and fatal disease. we report a rare case with longstanding sle who presented with fever. autopsy showed multiple small shallow-based ulcers in the antrum. histologic examination showed invasive mucormycosis. this is a rare case of invasive gastric mucormycosis localized exelusively in the stomach.

conclusions although strongyloidiasis is not endemic in usa, immigration obscured the geographical barrier of endemicity. the diagnosis can be difficult because of nonspecific symptoms and lack of sensitivity of microscopic diagnosis. although eosinophilia is a common finding in patients with chronic strongyloidiasis, it is unreliable indicator of active infection, especially in immunosuppresse...

abscess formation following intramuscular injections is rare and they are most commonly seen in immunocompromised individuals. in this case series we present a cohort of three patients presented to us in a critically ill condition with an abscess due to intramuscular injection. vancomycin resistant staphylococcus aureus was isolated from all three patients. these patients posed a major challeng...

toxoplasma encepfiautis (te) is rare in pediatric patients, but it is an emerging opportunistic infection in the increasing number of immunocompromised hosts. it should be considered in patients who present with fever and evolving cns symptoms. the outcome of these patients is always poor because of delay in diagnosis. we report one case of toxoplasma encephalitis in a child without hiv infecti...
