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.

Though there are vaccines against Pneumococci and Influenza viruses, currently there is no immunisation against Respiratory Syncytial Virus (RSV).
During that extra time, the pneumococci are gaining in numbers, causing more inflammation, and we see those clinical signs of fever, redness, and swelling at the site of infection, and pain.
Penicillin non-susceptibility was demonstrated in 56% of pneumococci in this study, this goes along with findings in other countries in the region.
15) The relationship between antimicrobial resistance and exposure is complicated by the emergence of multiply-resistant pneumococci that may be selected by several classes of antibiotics.
STREPTOCOCCUS PNEUMONIAE is one of the principal bacterial pathogens of infants and children worldwide, and the rising prevalence of pneumococci with decreased susceptibility to penicillin and to cephalosporins has complicated the management of pneumococcal infections.
2% (seven of 2340) of pneumococci were nonsusceptible (MIC: [greater than or equal to]4 [micro]g/mL) to levofloxacin in 1998 and 0.
Pneumococci are a major cause of ear infections and penicillin is usually the treatment.
Xylitol, which is derived from birch trees, has been shown to slow the growth of bacteria called pneumococci, which are a common cause of ear infections in children.
Pneumococci may also cause otitis media (middle ear infection) and sinusitis.
Only ICD-9-CM codes for which the numbers of an organism were substantial were analyzed: pneumococci, Klebsiella spp.
Penicillin has been the drug of choice for treatment of pneumococcal infections but the increasing number of reports of penicillin resistant pneumococci (PRP) throughout the world makes it essential to determine the regional prevalence of PRP [3,7, 8].
