BACKGROUND
Carbohydrates often accomplish as cell-surface receptors for microorganisms and influenza virus preferentially binds to sialic acid through the viral haemagglutinin. The virus may attach not only to the epithelium in the airways, but also to the surface ocular epithelium.

To
We examined two children from the same family who had purulent conjunctivitis. Isolates of Neisseria species were obtained from eye cultures and Gram stain of conjunctival scrapings disclosed many gram-negative intracellular diplococci. Colony structure and growth characteristics of the organism
A new Moraxella strain was isolated from angular conjunctivitis. It is characterized by the ability to produce acid from several carbohydrates, by its ability to produce indole, and by a lack of catalase activity.
The bacterium Moraxella bovis is the causative agent of an economically important disease of cattle: Infectious Bovine Keratoconjunctivitis (IBK), otherwise known as pinkeye. Little is known regarding the structure of the carbohydrates produced by M. bovis. The structure of a capsular polysaccharide
The greater susceptibility to the lethal effects of bacterial endotoxin (heat-killed Salmonella typhimurium or Escherichia coli lipopolysaccharide, in mice infected with an attenuated strain of Mycobacterium tuberculosis (BCG) was confirmed. It reached a maximum at 2 weeks postinfection and
The chlamydiae are obligate intracellular parasites that develop and multiply within a vacuole (termed an inclusion) that does not fuse with lysosomes. Inclusion morphology varies dramatically among the different chlamydiae, particularly within the species Chlamydia psittaci. Some strains develop
OBJECTIVE
Most causes of childhood blindness are treatable or preventable. Knowledge of parents' awareness and perception of eye problems is important in helping to understand parents' eye care seeking behavior. This understanding becomes necessary as early detection and intervention can be
Elementary bodies (EB) of Chlamydia trachomatis serotypes C, E, and L2 were extrinsically radioiodinated, and whole-cell lysates of these serotypes were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Autoradiography of the polypeptide profiles identified a major
