pneumococcus

 [noo″mo-kok´us]
Streptococcus pneumoniae. adj., adj pneumococ´cal.

Strep·to·coc·cus pneu·mo·ni·ae

a species of gram-positive, lancet-shaped cocci and diplococci frequently occurring in chains; cells are readily lysed by bile salts. Virulent forms are enclosed in type-specific polysaccharide capsules, the basis for an effective vaccine. Normal inhabitants of the respiratory tract, and the most common cause of lobar pneumonia, they are the most common causative agents of meningitis, and pneumonia worldwide, and also cause otitis media, sinusitis, and other infections. It is the type species of the former genus Diplococcus.

n. pl. pneumo·cocci (-kŏk′sī′, -kŏk′ī′)
A nonmotile, gram-positive bacterium (Streptococcus pneumoniae) that is the most common cause of bacterial pneumonia and is a cause of meningitis and other infectious diseases.

pneumococcus

[no̅o̅′mōkok′əs] pl. pneumococci
Etymology: Gk, pneumon + kokkos, berry
a gram-positive diplococcal bacterium of the species Streptococcus pneumoniae, the most common cause of bacterial pneumonia. More than 85 subtypes of this organism are known. A vaccine protective against 35 serotypes has been developed and is recommended for those over 65 years of age, those with a chronic lung disease, or those with human immunodeficiency virus infection.

Her research focuses on using genomic data to understand the population structure and evolution of pneumococcus.
They also showed that during recombination, the bacteria also traded a number of other parts of the genome at the same time, a phenomenon never before observed in natural populations of pneumococcus.
As well as decreasing pneumonia in children, Dr Brown says vaccinating young people also reduces the chance of adults getting pneumonia, because they can catch the pneumococcus bacteria from youngsters.
Close contact, one person to another, is the way the pneumococcus gets from one person to another, usually within three feet--the breathing zone--and then of course we hug and kiss our relatives and friends and that all provides an opportunity for the pneumococcus to spread.
It is a seven-valence vaccine, meaning it protects against the seven most common pneumococcus types in Cuba and Latin America.
Outbreaks caused by the pneumococcus strain of bacteria are extremely rare and this outbreak was the first of its kind involving children in a school to be reported in the UK.
He said these were rare circumstances and that the pneumococcus germ was different to the meningococcous germthat usually causes meningitis.
