Oedematous pericardium of a goat that died of heartwater disease, caused by infection with Ehrlichia ruminantium, transmitted by Amblyomma ticks in Africa and Caribbean. On post mortem examination, a light yellow transudate that coagulates on exposure to air is often found within the thorax, pericardium, and abdomen. Most fatal cases have the ...
Water contaminated with the bacteria Mostly diarrhea. Can cause death in immunocompromised individuals, the very young, and the elderly due to dehydration from prolonged illness. M. marinum infection: Mycobacterium marinum: Naturally occurs in water, most cases from exposure in swimming pools or more frequently aquariums; rare infection since ...
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.
Ehrlichiosis is a tick-borne [3] bacterial infection, [4] caused by bacteria of the family Anaplasmataceae, genera Ehrlichia and Anaplasma. These obligate intracellular bacteria infect and kill white blood cells. The average reported annual incidence is on the order of 2.3 cases per million people. [5]
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.
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 .
Pathogenic exogenous bacteria can enter a closed biological system and cause disease such as Cholera, which is induced by a waterborne microbe that infects the human intestine. [2] Exogenous bacteria can be introduced into a closed ecosystem as well, and have mutualistic benefits for both the microbe and the host. [ 1 ]
