BACKGROUND The bacteria Escherichia coli K4 produces a capsular polysaccharide (K4 CPS) whose backbone is similar to the non sulphated chondroitin chain. The chondroitin sulphate is one of the major components of the extra-cellular matrix of the vertebrate connective tissues and a high value molecule, widely employed as active principle in the treatment of osteoarthritis. It is usually obtained...

streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. capsular polysaccharide (cps) of s. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of s. iniae infection in aquatic animals. the cpsdgene was determined to be highly conservative in capsule polysaccharide operon. prokaryotic expression of th...

PURPOSE The ocular humors are relatively low in protein, yet cell growth in the human capsular bag still occurs after extracapsular cataract extraction (ECCE) surgery. This resilient growth gives rise to posterior capsule opacification (PCO) in a significant proportion (30%) of patients. This study compared the ability of human lens cells to proliferate in serum-supplemented and protein-free me...

The capsule has been implicated in the virulence of the swine pathogen Erysipelothrix rhusiopathiae, a rod-shaped, intracellular Gram-positive bacterium that has a unique phylogenetic position in the phylum Firmicutes and is a close relative of Mollicutes (mycoplasma species). In this study, we analyzed the genetic locus and composition of the capsular polysaccharide (CPS) of the Fujisawa strai...

1. A washed bacterial suspension of Donovan microorganisms cultivated in the yolk of chick embryos was used as an antigen in intracutaneous tests in 6 cases of granuloma inguinale in the active stage of the disease. These injections were responded to by an extensive erythematous and edematous reaction that reached its height in 24 hours and disappeared within 48 hours later. Four control cases ...

recently, small incision cataract extraction by phaco and implantation of a foldable intraocular lense with topical anesthesia has used in an attempt to decrease the complication of general anesthesia and peribulbar injection. to compare effects and complications of topical, local and general anesthesia, 92 patients admitted to imam hosein hospital for cataract surgery, were randomly assigned t...

In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...
