Functional characterization of a broad and potent neutralizing monoclonal antibody directed against outer membrane protein (OMP) of Salmonella typhimurium.

In the present study, we have generated a murine monoclonal antibody (mAb) named Sal-06 by using the crude outer membrane protein preparation of Salmonella enteric subsp. enterica serovar Typhimurium ATCC 14028 strain as antigen. Sal-06mAb belonging to IgG1 isotype demonstrated broad cross-reactivity to standard and isolated strains of genus Salmonella and others such as Escherichia coli, Klebsiella pneumonia, and Proteus mirabilis.

Application of monoclonal antibodies generated against Panton-Valentine Leukocidin (PVL-S) toxin for specific identification of community acquired methicillin resistance Staphylococcus aureus.

Panton-Valentine Leukocidin (PVL) produced by community acquired methicillin Staphylococcus aureus (CA-MRSA) involved in skin and soft-tissue infections and necrotizing pneumonia comprised of two fractions, namely PVL S and PVL F. In the present study, three monoclonal antibodies designated as MAb1, MAb9 and MAb10 were generated against recombinant PVL-S (35kDa) protein of S. aureus.

Functional characterization and evaluation of in vitro protective efficacy of murine monoclonal antibodies BURK24 and BURK37 against Burkholderia pseudomallei.

Burkholderia pseudomallei, the causative agent of melioidosis has been recognized by CDC as a category B select agent. Although substantial efforts have been made for development of vaccine molecules against the pathogen, significant hurdles still remain. With no licensed vaccines available and high relapse rate of the disease, there is a pressing need for development of alternate protection strategies.

Immuno capture PCR for rapid and sensitive identification of pathogenic Bacillus anthracis.

Immuno capture PCR (IPCR) is a technique capable of detecting the pathogens with high specificity and sensitivity. Rapid and accurate detection of Bacillus anthracis was achieved using anti-EA1 antibodies to capture the cells and two primer sets targeting the virulence factors of the pathogen i.e.

Monoclonal antibodies against recombinant hemolysin BL complex of Bacillus cereus.

A three component complex system, designated hemolysin BL (HBL), is believed to be the major diarrheal toxin of Bacillus cereus. Identification of HBL toxin by immunoassay is advantageous over PCR as it detects the expressed form of the gene, thereby differentiating pathogenic strains from nonpathogenic strains. However, most of the immunoassays, like the BCET RPLA kit, are based on the utilization of polyclonal antisera, which show cross-reactivity at times with other Bacillus species.
