Final answer:
The bacteria Streptococcus pyogenes causes strep throat, while Streptococcus pneumoniae and Haemophilus influenzae are common causes of pneumonia, with other forms being due to Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Chlamydia trachomatis.
Step-by-step explanation:
The bacteria responsible for causing sore throat and pneumonia include several pathogenic species. Streptococcus pyogenes is commonly associated with strep throat, which can lead to symptoms such as pain and swelling in the throat. This bacterium produces exotoxins that can damage the pharynx and other body parts. Furthermore, pneumonia, characterized by inflammation and fluid in the alveoli, can be caused by various bacteria, including Streptococcus pneumoniae and Haemophilus influenzae. Streptococcus pneumoniae, in particular, is known for being multidrug resistant and is a leading cause of community-acquired bacterial pneumonia. Other bacteria such as Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Chlamydia trachomatis can also cause forms of pneumonia, with varying degrees of severity and transmission modes.
