Nanoparticle-detained toxins for safe and effective vaccination
Toxoid vaccines--vaccines based on inactivated bacterial toxins--are routinely used to promote antitoxin immunity for the treatment and prevention of bacterial infections. Following chemical or heat denaturation, inactivated toxins can be administered to mount toxin-specific immune responses. However, retaining faithful antigenic presentation while removing toxin virulence remains a major chall...
متن کاملLB Broth-lyophilized Rabbit Anti-sheep Cell Haemolysin as a Simple Culture Medium for Cultivation of Leishmania Major Promastigotes
Background and Aims: The protozoan parasites of the genus Leishmania are the causative agents of various clinical diseases. Different methods of cultivation of Leishmania parasites are available. In the present study, the efficacy of the LB broth with rabbit lyophilized anti-sheep red blood cell haemolysin was evaluated in the cultivation of promastigotes of Leishmania major. Materials and Met...
متن کاملPhenotypic characters of urinary isolates of Pseudomonas aeruginosa & their association with mouse renal colonization.
BACKGROUND & OBJECTIVE Very few studies regarding production of virulence factors in different predominant serotypes of uropathogenic Pseudomonas aeruginosa are available and they have not been correlated to in vivo pathogenicity in the urinary tract. This study was carriedout with the objective to analyze the phenotypic characters of uroisolates of P. aeruginosa in vitro and to study the assoc...
متن کاملGroup B streptococcal haemolysin and pigment, a tale of twins
Group B streptococcus [(GBS or Streptococcus agalactiae)] is a leading cause of neonatal meningitis and septicaemia. Most clinical isolates express simultaneously a β-haemolysin/cytolysin and a red polyenic pigment, two phenotypic traits important for GBS identification in medical microbiology. The genetic determinants encoding the GBS haemolysin and pigment have been elucidated and the molecul...
متن کاملEffects of whey protein edible coating on bacterial, chemical and sensory characteristics of frozen common Kilka
The objective of current study was to investigate the effects of whey protein coating on the quality of common kilka during frozen storage period. For this study, common kilka was coated with 12% whey protein concentration. Also, non- coated kilka was used as a control sample. Coated and non-coated samples were then stored at -18 oC for six months. Bacterial, chemical and sensory properties of ...
