Streptococcus Pseudopneumoniae
''Streptococcus pseudopneumoniae'' is a gram-positive coccus that may cause pneumonia in humans. It was first described in 2004. The organism is often mistaken for '' S. pneumoniae'' and its clinical importance is as yet uncertain. It seems likely that most cases of ''S. pseudopneumoniae'' pneumonia are misdiagnosed as ''S. pneumoniae''. The bacterium has a number of features that allows it to be distinguished from ''S. pneumoniae'': * There is no pneumococcal capsule (and is therefore not typable). * It is not soluble in bile. * It is sensitive to optochin when incubated in ambient air, but appears resistant or to have indeterminate susceptibility when incubated in 5% carbon dioxide. * Commercial DNA probe hybridization tests (e.g., AccuProbe ''Streptococcus pneumoniae'' culture identification test; Gen-Probe, San Diego, CA) are falsely positive. Penicillin is the treatment of choice. Most reported isolates are resistant to erythromycin and to tetracyclin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streptococcus Pneumoniae
''Streptococcus pneumoniae'', or pneumococcus, is a Gram-positive, spherical bacteria, hemolysis (microbiology), alpha-hemolytic member of the genus ''Streptococcus''. ''S. pneumoniae'' cells are usually found in pairs (diplococci) and do not form Bacterial morphological plasticity, spores and are non motile. As a significant human pathogenic bacterium ''S. pneumoniae'' was recognized as a major cause of pneumonia in the late 19th century, and is the subject of many humoral immunity studies. ''Streptococcus pneumoniae'' resides asymptomatically in healthy carriers typically colonizing the respiratory tract, sinuses, and nasopharynx, nasal cavity. However, in susceptible individuals with immunocompromised, weaker immune systems, such as the elderly and young children, the bacterium may become pathogenic and spread to other locations to cause disease. It spreads by direct person-to-person contact via respiratory droplets and by auto inoculation in persons carrying the bacteria in ...

Erythromycin
Erythromycin is an antibiotic used for the treatment of a number of bacterial infections. This includes respiratory tract infections, skin infections, chlamydia infections, pelvic inflammatory disease, and syphilis. It may also be used during pregnancy to prevent Group B streptococcal infection in the newborn, and to improve delayed stomach emptying. It can be given intravenously and by mouth. An eye ointment is routinely recommended after delivery to prevent eye infections in the newborn. Common side effects include abdominal cramps, vomiting, and diarrhea. More serious side effects may include ''Clostridioides difficile'' colitis, liver problems, prolonged QT, and allergic reactions. It is generally safe in those who are allergic to penicillin. Erythromycin also appears to be safe to use during pregnancy. While generally regarded as safe during breastfeeding, its use by the mother during the first two weeks of life may increase the risk of pyloric stenosis in ...

Tetracycline
Tetracycline, sold under various brand names, is an antibiotic in the tetracyclines family of medications, used to treat a number of infections, including acne, cholera, brucellosis, plague, malaria, and syphilis. It is available in oral and topical formulations. Common side effects include vomiting, diarrhea, rash, and loss of appetite. Other side effects include poor tooth development if used by children less than eight years of age, kidney problems, and sunburning easily. Use during pregnancy may harm the baby. It works by inhibiting protein synthesis in bacteria. Tetracycline was patented in 1953 and was approved for prescription use in 1954. It is on the World Health Organization's List of Essential Medicines. Tetracycline is available as a generic medication. Tetracycline was originally made from bacteria of the genus ''Streptomyces''. Medical uses Spectrum of activity Tetracyclines have a broad spectrum of antibiotic action. Originally, they possessed some lev ...

Streptococcaceae
Streptococcaceae, from Ancient Greek στρεπτός (''streptós''), meaning "twisted", and κόκκος (''kókkos''), meaning "sphere", are a family of gram-positive bacteria, placed within the order Lactobacillales. Representative genera include '' Lactococcus'', '' Lactovum'', and ''Streptococcus''.
