Streptococcus
🔍 Introduction to Streptococcus
Streptococcus is one of the most widespread genera of bacteria found in the human body and the environment. These Gram-positive cocci, typically forming chains or pairs, are capable of causing a wide range of infections—ranging from mild conditions (such as a sore throat) to more serious diseases like sepsis, neonatal infections, and rheumatic fever.
While streptococcus bacteria often exist harmlessly on the skin, in the throat, or on other mucosal surfaces, certain strains can lead to significant inflammation and illness. Understanding the nature of streptococcus, how it spreads, and how it is effectively treated is essential, as it is a highly contagious bacterium with diverse clinical manifestations.
