Similarly, group B streptococcus typically denotes Streptococcus agalactiae, although minor beta-hemolytic group B streptococci like S. troglodytidis exist. [15] While most streptococcal illnesses in humans originate from species adapted to humans, such as S. pneumoniae or S. pyogenes, there are zoonotic species capable of causing infections. [15]
The report, which was conducted by Epic Research, a company that analyzes electronic health records, found that cases of strep throat hit a five-year high in February and March. They were also ...
