"Bacteria Causing: Unseen Threats Lurking Among Us" E. Coli bacterium: A common culprit behind foodborne illnesses, this strain of bacteria can cause severe gastrointestinal distress if ingested. Staphylococcus aureus bacteria: Known for causing skin infections, these bacteria can also lead to more serious conditions such as pneumonia or bloodstream infections. Chains of Streptococcus pyogenes bacteria: Responsible for strep throat and other respiratory infections, these bacterial chains spread easily among close contacts. Neisseria meningitidis bacteria: This dangerous bacterium is a leading cause of meningitis, an infection that affects the brain and spinal cord, often resulting in life-threatening complications. Clostridium tetani bacterium: Found in soil and animal feces, this bacterium produces a toxin that causes tetanus—an extremely painful condition affecting the muscles and nerves. F/col TEM of Corynebacterium diphtheria: The microscopic image reveals the presence of Corynebacterium diphtheria—a notorious pathogen responsible for diphtheria, a highly contagious respiratory disease with potential fatal consequences if left untreated. Neisseria meningitidis bacteria (again): These fast-spreading bacteria are known to cause outbreaks of meningococcal disease—another form of meningitis—with symptoms ranging from fever and headache to rash and even death if not promptly treated. Bacteroides gingivalis bacteria: Often found in dental plaque, these oral pathogens contribute to gum diseases like periodontitis by attacking the tissues supporting teeth. Haemophilus influenzae bacterium: Despite its name suggesting involvement in flu-like illnesses, this bacterium primarily causes respiratory tract infections such as bronchitis or ear infections in children. From food poisoning to life-threatening diseases like meningitis or tetanus, these bacteria remind us of the invisible threats that surround us.
