Isolation and Characterization of “Heavy Chain Antibody” Variable Domain Gene of Indian Desert Camel (Camelus dromedarius, L.)
Abstract: Camelids have “heavy chain antibodies” (HCAbs) of IgG isotype (IgG2 and IgG3 subtypes) and lack light chains and heavy chain constant domain 1 (CH1) in their structure. The molecular biological features of VHH (i.e., antigen binding variable domain of HCAbs) gene isolated from Indian desert camel were examined as a prelude to construct VHHs-phage display library. VHH cDNA was synthesized by reverse transcription-polymerase chain reaction (RT-PCR) from B lymphocyte mRNA, …

A Study for the Presence of Enterococcal Virulence Factors Gelatinase, Haemolysin among Clinical Isolates in a Tertiary Care Hospital
Abstract: Enterococcus, considered a normal commensal of intestinal tract, is fast emerging pathogen causing serious infection. Despite the increasing importance of Enterococcus as opportunistic pathogens, their virulence factors are still poorly understood. The potential virulence factors of Enterococci include production of enterococcal surface protein (Esp), gelatinase, and haemolysin. Gelatinase- and haemolysin-producing strains of Enterococcus faecalis have been shown to be virulent in animal models of enterococcal infections. This study was undertaken …

Optimization of Microbial Cellulose Production by the Newly Isolated Acetobacter sp. DR-1 under Laboratory Conditions
Abstract: Cellulose is the most abundant natural biopolymer on the earth, synthesized by plants, algae and also some species of bacteria. It is also produced by some animals (e.g., tunicates).Cellulose constitutes one of the three principal components present in plant, namely cellulose, hemi-cellulose and lignin. However, the degree of polymerization and crystallinity of bacterial cellulose is considerable high than that of plant cellulose. In microbes, cellulose is normally produced as exo-polysaccharide, …
