I remember getting a bad lung infection‚ pneumonia‚ caused by Streptococcus pneumoniae‚ a few years back. I was very sick with a high fever‚ shortness of breath‚ fatigue‚ chest pain‚ and greenish-yellow – sometimes even bloody – mucus‚ which I consistently coughed up. I suffered for roughly a month or so before my pneumonia finally disappeared and I healed up. Being an otherwise healthy individual‚ yet still experiencing the symptoms for such a lengthy amount of time‚ made me wonder about how S.

most commonly caused by streptococcus species otherwise known as step throat‚ which is typically found in children of that age group. It is very rare to find children under the age of 2 years old to catch this infection and patient history is sometimes helpful when trying to identify the strand of tonsillitis the patient has. Most of the time tonsillitis is caused by viruses‚ the rest of the time it is caused by the same bacteria that causes strep throat (streptococcus). Bacteria causes 15-30%

grown drastically to over 10 in the 2000’s. The studies from “You Decide: What Can We Do About Antibiotic-Resistance Bacteria”‚ show how antibiotics affect bacteria over time. 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.

Pneumonia accounts for 13% of all infectious 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

Cocci ● They are differently arranged ● They can form pairs (diplococcus)‚ chains (streptococcus)‚ or clusters (staphylococcus) ● They are spherical in shape 2.) Bacilli ● They can also occur in chains (streptobacillus) ● They are spherical in shape 3.) Spirilla ● They are spiral in shape Bioremediation ● “Oil-eating bacteria” ● Scientists

Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

She had a Group A Streptococcal infection- to be more specific since the bacteria was a gram positive cocci that grows in chains it was caused by Streptococcus pyogenes. The symptoms she had that matched were discolored skin‚ swelling‚ hot sensation‚ and pain. With group a streptococcal infection amputation may sometimes be needed.

Before the discovery of antibiotics‚ nothing much could be done by anybody and deaths on large scale were claimed. For instance Streptococcus pyogenes was the cause of half of all post-birth deaths[2] and Staphylococcus aureus was fatal in 80% of infected wounds and the tuberculosis and pneumonia bacteria were famous killers. Now‚ discovery of antibiotics has enabled the medical line
