Fine structure of Listeria monocytogenes in relation to protoplast formation.
Among the eight strains of Listeria monocytogenes tested for lysozyme sensitivity, two were resistant to lysozyme but became sensitive after lipase pretreatment. Among the other six, one was very sensitive to lipase and another one was extremely susceptible to lysozyme. Stable protoplasts were formed from the lysozyme-resistant strain (42) by lipase and lysozyme treatment, which completely dige...
متن کاملStructure of internalin C from Listeria monocytogenes.
The crystal structure of internalin C (InlC) from Listeria monocytogenes has been determined at 2.0 A resolution. Several observations implicate InlC in infection: inlC has the same transcriptional activator as other virulence genes, it is only present in pathogenic Listeria strains and an inlC deletion mutant is significantly less virulent. While the extended concave receptor-binding surfaces ...
متن کاملDETERMINATION 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 ...
متن کاملEpidemiological 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...
متن کاملIsolation, composition, and structure of membrane of Listeria monocytogenes.
The plasma membrane of Listeria monocytogenes strain 42 was prepared by osmotic lysis of protoplasts with tris(hydroxymethyl)aminomethane (Tris) buffer, pH 8.2, containing MgCl(2) and glucose, followed by washing with NaCl and MgCl(2) in Tris buffer. Electron microscopy showed that the preparation was not contaminated with cytoplasmic material. The membrane preparation was composed of 55 to 60%...
