When treating illnesses caused by gram-positive bacteria, the best option depends on: diphtheria is the primary pathogenic organism in this group. However, these organisms rarely cause sickness and usually affect people with compromised immune systems.Ĭ. There are about 30 Corynebacterium bacteria associated with human disease. But in people with weakened immune systems, the bacterium can cause life-threatening conditions like: In healthy people, it typically causes mild symptoms of foodborne illness. The only pathogenic Listeria bacteria is L. If the toxin causes an infection, it’s called tetanus. The spores can be found in soil, ash, and on rusty tools. tetani spores produce the tetanus toxin, a neurotoxic substance. It typically occurs after taking antibiotics. diff, usually affects older individuals in hospital. Symptoms include diarrhea and abdominal cramps that last for less than 24 hours. If a human eats contaminated meat, they can get food poisoning. perfringens is usually associated with meat production and processing. botulinum produce the botulinum toxin, the most dangerous toxin to humans. Like bacilli, these bacteria form toxins that lead to serious conditions.Ĭlostridia are usually involved with foodborne illnesses, but the most concerning bacteria include: Clostridium botulinum cereus causes:Ībout 30 Clostridia species cause disease in humans. It’s most associated with illness due to eating undercooked or reheated rice. cereus is a spore-forming bacterium that’s found in the soil and some foods. itchy bump that turns into a sore with black centerī.Humans can get anthrax through inhalation or contact with infected animals.ĭepending on how anthrax is spread, it can cause a variety of symptoms. anthracis spores produce the anthrax toxin, which causes serious illness. Most bacilli aren’t pathogenic to humans, but the following two can cause severe medical conditions. BacillusĪs spore-forming bacteria, bacilli make spores that release toxins. They cause biliary and urinary tract infections. This includes:Įnterococci are primarily found in the colon. agalactiae usually cause infections in newborns. pneumoniae is the most common cause of community-acquired pneumonia. In general, other streptococci groups may cause foodborne illnesses with a sore throat. The following organisms are the most prevalent. Streptococci bacteria are also common pathogenic bacteria. uncomplicated urinary tract infections (most common).saprophyticus, which is normally found in the genital tract and perineum.
