illnesses in infants younger than 2 years. Newborns with pneumonia commonly present with poor feeding and irritability‚ as well as tachypnea‚ retractions‚ grunting‚ and hypoxemia. Infections with group B Streptococcus‚ Listeria monocytogenes‚ or gram-negative rods (eg‚ Escherichia coli‚ Klebsiella pneumoniae) are common causes of bacterial pneumonia. Group B streptococci infections are most often transmitted to the fetus in utero. The most commonly isolated virus is respiratory syncytial virus (RSV).

Concomitant therapy with dexamethasone initiated before or at the time of antimicrobial therapy has been demonstrated to improve morbidity and mortality in adults with Streptococcus pneumoniae infection. Within the United States‚ almost 30 percent of strains of pneumococci‚ the most common etiologic agent of bacterial meningitis‚ are not susceptible to penicillin. Among adults in developed countries‚ the mortality rate from bacterial

Streptococcus pneumoniae is the most common causative agent in the Untied States causing 30-50% of all cases. In recent years many strains of S. pneumoniae have become drug-resistant which makes treatment very difficult and increases the mortality rate. Neisseria meningitidis is the second leading cause of meningitis in the Untied

Bacteria are uncommon pathogens but may include Mycoplasma pneumoniae‚ Chlamydophila pneumoniae‚ Bordetella pertussis‚ streptococcus pneumoniae‚ and haemophilus influenzae. * Damage caused by irritation of the airways leads to inflammation and leads to neutrophils infiltrating the lung tissue. * Mucosal hypersecretion is promoted by a substance

From 1995 to 1998 the resistance of penicillin by the bacteria known as Streptococcus Pneumoniae increased consistently. If patients continue to become resistant to the antibiotics being prescribed then the antibiotics could become extinct in the sense that they would no longer be valuable for their intended purpose. According to “You

The most common cause is a bacterium called Streptococcus pneumoniae‚ but in individual cases of pneumonia the cause is often not known. Some of these bacteria can live in the nose or throat without causing problems‚ and in most cases it is not known why they then suddenly make people ill. Others can be spread
