Bacterial skin infections include: Impetigo is a highly contagious bacterial skin infection commonly seen in children. [17] It is caused by Staphylococcus aureus, and Streptococcus pyogenes. [18] Erysipelas is an acute streptococcus bacterial infection [19] of the deeper skin layers that spreads via with lymphatic system.
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
Rat-bite fever (RBF) is an acute, febrile human illness caused by bacteria transmitted by rodents, in most cases, which is passed from rodent to human by the rodent's urine or mucous secretions. Alternative names for rat-bite fever include streptobacillary fever, streptobacillosis, spirillary fever, bogger, and epidemic arthritic erythema.
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
It is an unusual cause of infection and when it is cultured, it is most usually found mixed with other organisms. Infections most commonly occur in patients with cancers of the head and neck, [ 10 ] but can occur in human bite infections, especially " reverse bite ", " fight bite ", or " clenched fist injuries ". [ 11 ]
It has been found in the human gastrointestinal tract, female reproductive system and male prostate. [2] Occasionally it can cause disease by spreading to other areas, including bloodstream infections, liver abscesses, bacterial vaginosis and meningitis. [2]
They are found in the human colon and feces and have been implicated as a cause of ulcerative colitis, liver and anal abscesses and systemic bacteremia. [2] [3] The type strain for this genus, Eggerthella lenta, was known as Eubacterium lentum prior to 1999. [4] [5] The genus is named for Arnold Eggerth, who first described the organism in 1935 ...
Their growth and reproduction within their hosts can cause disease. "Germ" refers to not just a bacterium but to any type of microorganism, such as protists or fungi, or other pathogens that can cause disease, such as viruses, prions, or viroids. [1] Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the ...
