Porin proteins of Gram-negative bacteria are outer membrane proteins that act as receptors for bacteriophages and are involved in a variety of functions like solute transport, pathogenesis, and immunity. Salmonella enterica serovar Typhi (S. Typhi), a Gram-negative bacterium, is the causative agent of typhoid fever. Porins of S. Typhi have been shown to(More)
Clostridium perfringens is a medically important clostridial pathogen and an etiological agent causing several diseases in humans and animals. C. perfringens and its toxins have been listed as potential biological and toxin warfare (BTW) agents; thus, efforts to develop strategies for detection and protection are warranted. Forty-eight extracellular(More)
The present study demonstrated the combined effect of 24-epibrassinolide and salicylic acid against lead (Pb, 0.25, 0.50, and 0.75 mM) toxicity in Brassica juncea seedlings. Various parameters including water status, metal uptake, total water- and lipid-soluble antioxidants, metal chelator content (total thiols, protein-bound thiols, and non-protein-bound(More)
Shigella dysenteriae is the causative agent of the third commonest bacterial disease for childhood diarrhoea and responsible for millions of deaths per year. It produces potent toxin termed Shiga toxin which is listed in category B biological warfare agent of CDC, USA. Earlier we have reported production of recombinant Shiga toxin B subunit that produced(More)

Glanders, caused by the Gram-negative, nonmotile bacterium Burkholderia mallei, is a contagious and highly fatal disease of equines. During the last decade, the number of glanders outbreaks has increased steadily. The disease also has high zoonotic significance and B. mallei is listed biological warfare agent. The complement fixation test (CFT) is a(More)
The present work was undertaken to study the effects of 24-epibrassinolide (24-EBL) on percent germination, growth (root length, shoot length, fresh weight and dry weight), lipid peroxidation, sodium and potassium ion concentrations, proline content, total osmolyte content, level of antioxidants (ascorbic acid, tocopherol and glutathione) in 7-day old(More)
