چکیده
Acute bacterial conjunctivitis is usually caused by the pneumococcus or Haemophilus influenzae, but other organisms are sometimes involved and it is important to identify these exactly. Among the less common pathogens are the neisseria, and both Neisseria gonorrhoeae and N meningitidis have been implicated in ophthalmic infections. N gonorrhoeae is particularly associated with severe destructive ophthalmia in the newborn but may also cause purulent conjunctivitis in adults in whom infections by N meningitidis also occur from time to time. These two organisms are very similar, but for obvious epidemiological reasons it is important to distinguish between them. Coagglutination tests are available to identify N gonorrhoeae but not for N meningitidis. The differentiation of these two organisms therefore still relies mainly on classic methods of sugar fermentation. In these tests N gonorrhoeae produces acid from glucose only, while N meningitidis produces acid from glucose and maltose;' in many laboratories this is still the only way of identifying them. Difficulty comes about because there are some strains of N meningitidis which do not ferment maltose promptly and are therefore likely to be wrongly identified.2

Neutralizing monoclonal antibodies to human rotavirus and indications of antigenic drift among strains from neonates.
Cells producing neutralizing monoclonal antibodies to a serotype 3 human neonatal rotavirus strain RV-3 were derived by fusion of hyperimmunized mouse spleen cells with mouse myeloma cells. As ascites fluid, three rotavirus-neutralizing monoclonal antibodies were characterized by hemagglutination inhibition and reacted with 17 cultivable mammalian rotaviruses representing five virus serotypes, ...

متن کاملGenetic and antigenic variation of capsid protein VP7 of serotype G1 human rotavirus isolates.
The deduced amino acid sequences of the outer capsid protein, VP7, of serotype G1 rotavirus clinical isolates collected over a 6 year period (1990-1995) in Melbourne, Australia, were examined. Phylogenetic analysis characterized the sequences into two discrete clusters representing two of the four global lineages of human G1 VP7 proteins. Antigenic characterization using a panel of serotype G1-...
