DETERMINATION OF DOMINANT SEROVARS OF LISTERIA MONOCYTOGENES

Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...

Listeria monocytogenes Brain Abscess

Listeria monocytogenes is a Gram-positive bacilli that exhibits predilection to infect the central nervous system in immunocompromised individuals, especially those with hematologic malignancy, immunosuppressive agents use including corticosteroid, diabetes mellitus, and HIV infection. The most common manifestations include meningitis and rhombencephalitis, but brain abscess occurs rarely. Ther...

Listeria monocytogenes pathogenicity

Listeriolysin O (LLO) and ActA are essential virulence determinants for Listeria monocytogenes pathogenesis. Transcription of actA and hly , encoding LLO, is regulated by PrfA and increases dramatically during intracellular infection. The 5 ¢ untranslated regions (5 ¢ UTRs) of actA and prfA have been shown to upregulate expression of their respective gene products. Here, we demonstrate that the...

Epidemiological burden of Listeria monocytogenes in Iran

Objective(s): Listeria monocytogenes is a foodborne pathogenic bacteria causing the infection listeriosis, which possibly affects all people, particularly immunocompromised persons and pregnant women. This microorganism can be found in several processed foods, dairy products, raw milk, meat and fish products, seafoods, eggs, fruits, and vegetables. This review discusses about the epidemiologica...
