The U.S. Food and Drug Administration recently added potentially fatal Listeria monocytogenes infection to the list of opportunistic infections that can occur in patients who receive tumor necrosis factor inhibitor therapy. In this study, the first reported case of L monocytogenes cholecystitis associated with etanercept use is described. It also appears that tumor necrosis factor inhibitor the...

background the genus-listeria has two pathogenic species namely, listeria monocytogenes and listeria ivanovii. of these, l. monocytogenes is a well-known cause of abortion, encephalitis and septicaemia in man and animals. listeria ivanovii is an animal pathogen and in rare cases causes human infection. contamination of ovine carcasses during the slaughter and processing is a major risk for food...

Infectious bovine keratoconjunctivitis (IBK) is a multifactorial disease complex caused by opportunistic pathogens, classically those members of the genus Moraxella . However, IBK in some situations associated with other potentially pathogenic agents, which include Mycoplasma bovoculi , bovis Ureaplasma diversum herpesviruses, and Chlamydia sp. Ocular infections that may resemble are also Liste...

OBJECTIVE We have conducted a series of experiments to show that the bacteriocin piscicolin 126 (P126) retains antilisterial activity after injection into a mouse. METHODS Groups of mice were challenged intravenously with Listeria monocytogenes and treated with purified P126 at varying times before and after challenge to determine whether administration of this peptide reduced numbers of colo...

This study was carried out comparing the conventional methods (ISO 11290-1 and BAM method, 2008) and system mini-Vidas® (Biomerieux), for detection of Listeria sp. and Salmonella sp. in cooled sausage. The immunoenzymatic method has shown to be effective for the detection of target pathogens, it has presented itself as an excellent screening method.

AIM To investigate bacteriological quality in organically grown leaf lettuce, including the presence of selected pathogenic bacteria, and to obtain information about organic lettuce production, including fertilizing regimes. METHODS AND RESULTS Altogether 179 samples of Norwegian organically grown lettuce were collected from 12 producers. Escherichia coli was isolated from 16 of the lettuce s...
