Streptococcus, (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (“twisted berry”) refers to the bacteria’s characteristic grouping in chains that resemble a string of beads. Streptoco
Infectious keratitis is a common disease of the cornea that is potentially blinding. We report a caseof microbial keratitis caused by Streptococcus pneumoniae in a man with a one-week history ofocular pain, photophobia, redness and blurred vision. Laboratory evidence of infective agent in acorneal...
In contrast to group A streptococci or Streptococcus pneumoniae, cells of Streptococcus sanguis (group H) do not exhibit the irreversible effects of penicillin treatment, such as loss of viability or lysis. On the other hand, the same bacteria show typical effects of penicillin, such as morphologi...
targeting this region [55]. While these assays are considered to have a very good species specificity forS. pneumoniae[38], variants typical forS. pneumoniaein isolates from the Mitis group, as well as a Mitis-specific allele in pneumococcus, were occasionally observed [24,70]. ThepsaAgene, ...
