Introduction: The currently licensed seasonal influenza vaccines contain split, subunit or whole virions, typically in amounts of 15 µg hemagglutinin per virus strain for adult and up to 60 µg in elderly patients.

Aim: The present study reports safety data of the newly licensed, reduced dose vaccine with 6 µg of hemagglutinin per strain produced by Fluart (Hungary) after its first season on the market. The main objective of enhanced safety surveillance was to detect a potential increase in reactogenicity and allergic events that is intrinsic to the product in near real-time in the earliest vaccinated cohorts.

Background: One of the most important resistance mechanisms in bacteria is the increased expression of multidrug efflux pumps. To combat efflux-related resistance, the development of new efflux pump inhibitors is essential.

Materials And Methods: Ten phosphorus ylides were compared based on their MDR-reverting activity in multidrug efflux pump system consisting of the subunits acridine-resistance proteins A and B (AcrA and AcrB) and the multidrug efflux pump outer membrane factor TolC (TolC) of Escherichia coli K-12 AG100 strain and its AcrAB-TolC-deleted strain.

Background/aim: Bacterial resistance to antibiotics has become a serious problem in antibacterial chemotherapy and resistance of bacteria to chemically-unrelated anti-microbial agents can be associated with the over-expression of efflux pumps. The simultaneous therapy with efflux pump inhibitors (EPIs) could be a solution to improve the effectiveness of antibiotics. The response of an organism to an EPI often depends on how that molecule fits a particular site of a protein.

Even in asymptomatic cases of Chlamydia trachomatis infection, the aim of the antibiotic strategy is eradication of the pathogen so as to avoid the severe late sequelae, such as pelvic inflammatory disease, ectopic pregnancy, and tubal infertility. Although first-line antimicrobial agents have been demonstrated to be predominantly successful in the treatment of C. trachomatis infection, treatment failures have been observed in some cases.

We studied the role of isocitrate lyase in the interaction between Mycobacterium bovis BCG and mice. ApoB100-only LDLR-/- (B6;129S-ApoBtm2SgyLdlrtm1Her/J) mice were inoculated with M. bovis BCG harbouring plasmids carrying the gene for isocitrate lyase.

Chlamydophila pneumoniae is an obligate intracellular human pathogen, which causes acute respiratory tract infections and can also cause chronic infections. C. pneumoniae possess type III secretion system (TTSS), which allows them to secrete effector molecules into the inclusion membrane and the host cell cytosol.

Mycobacterium smegmatis is a species of rapidly growing saprophytes with a number of properties that make it an effective vaccine vector. Recombinant M. smegmatis expressing protective antigens of different pathogens and molecules modulating the immune responses offers some potential for reduction of the burden of tuberculosis, HIV and hepatitis B infections.

Chlamydophila pneumoniae possesses a type III secretion system (TTSS), which allows the bacteria to secrete effector molecules into the inclusion membrane and into the cytosol of the host cell. Low calcium response protein H (LcrH), as a part of the TTSS, is a chaperone protein expressed from the middle to late stages of the chlamydial developmental cycle. Gene of LcrH (CPn0811) in a 6His-tagged form was cloned from C.
