Across the placenta infections include Toxoplasma gondii, Treponema pallidum, Listeria monocytogenes, Plasmodium falciparum (malaria), rubella and cytomegalovirus (CMV). Ascending maternal infection and chorioamnionitis causing fetal infection, usually subsequent to prolonged rupture of membranes. Perinatal infection acquired during birth via the haematogenous or genital route. These include hu...

Acute graft-versus-host disease (GVHD) is characterized by the production of high levels of T helper 1 (Th1)-type cytokines. Bone marrow transplantation from allogeneic C57BL/6 cells to CBF(1) mice produced acute GVHD. Host resistance to Th1-driven Listeria monocytogenes was enhanced, whereas host resistance to Th2-driven Staphylococcus aureus was reduced during acute GVHD. These results sugges...

OBJECTIVE The prognosis of patients with rheumatic diseases has improved considerably following the use of biological therapies. However, an increase in the frequency of bacterial infections has been observed in patients receiving these therapies. In the present study we aimed to assess the frequency of Listeria monocytogenes infection in a large series of patients with rheumatic diseases on tr...

The phylogenetic interrelationships of members of the genus Listeria were investigated by using reverse transcriptase sequencing of 16S rRNA. The sequence data indicate that at the intrageneric level the genus Listeria consists of the following two closely related but distinct lines of descent: (i) the Listeria monocytogenes group of species (including Listeria innocua, Listeria ivanovii, Liste...

Abstract Bystander memory CD8 T cells can respond to other pathogens independently of their cell receptors (TCRs). Current dogma is that these improve control unrelated acute infections via TCR independent, innate-like functions. Contrary this, we observed mice with the transgenic P14 specific for lymphocytic choriomeningitis virus (LCMV), or chimera mice, succumb a typically sublethal bacteria...

Despite the recent advances in food pathogen detection, there still exist many challenges and opportunities to improve the current technology. Techniques such as immunomagnetic separation (IMS) and polymerase chain reaction (PCR) have paved the way for rapid and sensitive detection of foodborne pathogens, and advances in nanobiotechnology have allowed for miniaturization of devices. Collaborati...

BACKGROUND In developed countries invasive listeriosis is an infection of great concern to public health to due its clinical severity and high fatality rate, despite its low incidence. In Europe, statistically significant increasing trends in listeriosis notification rates from 2005 to 2009 were noted in Austria, Denmark, Hungary, Italy, Spain and Sweden. MATERIALS AND METHODS The standardize...

Listeria monocytogenes is a foodborne pathogen that can cause febrile gastroenteritis in healthy subjects and systemic infections in immunocompromised individuals. Despite the high prevalence of L. monocytogenes in the environment and frequent contamination of uncooked meat and poultry products, infections with this pathogen are relatively uncommon, suggesting that protective defenses in the ge...
