|
Neisseria meningitis:
|
a bean-shaped diplococcus that is related to the causative agent of gonorrhea, it can cause a life threatening infection of the meninges (tissue that covers the spinal cord and brain)
|
|
|
Rickettsia rickettsia
|
a tiny bacterium that is an obligate intracellular parasite and absorbs ATP from the host cell, transmitted by ticks, causes Rocky Mountain spotted tick fever
|
|
|
Bordetella pertussis
|
: a Gram-negative coccobacillus that causes a potentially severe upper respiratory infection commonly called whooping cough
|
|
|
Haemophilus aegyptius
|
a glycolytic facultative anaerobe in the family Pasteurellaceae, this Gram negative rod-shaped bacterium can cause conjunctivitis (pink-eye)
|
|
|
Treponema palladium
|
: a spirochete that is the causative agent of syphilis (a sexually transmitted disease which if left untreated can damage the aorta, heart, brain, eyes and bones)
|
|
|
Salmonella typhi
|
a facultative anaerobe in the Enterobacteriaceae family (related to Esherichia coli), it is a Gram negative short bacillus that is motile by means of peritrichous flagella, it is the causative agent of typhoid fever, causes diarrhea and can invade columnar epithelial cells of the intestines and can grow inside the cells, it can invade the blood system and spread through the body inside phagocytic cells, patients have a very high fever, profuse sweating, diarrhea, gastroenteritis and sometimes a rash of rose-colored spots
|
|
|
Campylobacter jejuni
|
an acid tolerant stomach pathogen that is a Gram negative, curved or helical rod shaped bacterium, it does not form spores, it is common in animal feces and a very common cause of gastroenteritis in humans, infections are frequently associated with undercooked poultry
|
|
|
Chlamydia psittaci
|
a tiny bacterium that is an obligate intracellular parasite and absorbs ATP from the host cell, unlike the Rickettsia, Chlamydia are transmitted by direct contact, C. psittaci causes parrot fever and is associated with exposure to infected birds
|
|
|
Rhizobium leguminosarum
|
: a Gram negative rod shaped bacterium that forms a nitrogen-fixing symbiosis in root nodules of legume plants such as peas, clover and beans
|
|
|
Helicobacter pylori:
|
an acid-tolerant Gram negative stomach pathogen that is involved in the formation of gastric ulcers
|
|
|
Escherichia coli
|
a rod shaped facultative bacterium that is a very common inhabitant of the mammalian large intestine and colon, used as an indicator organism for tests of food and water samples for fecal contamination, a leading cause of bladder infections
|
|
|
Agrobacterium tumefaciens
|
a rod shaped bacterium that infects wounded tissue of dicotyledonous plants, it can transfer a piece of DNA to the plant cells and cause some genetic modifications, the transformed plant cells may develop into tumors called crown galls and may excrete unusual amino acids such as octopine
|
|
|
Vibrio cholera
|
shaped like a bent rod, lives in river estuaries (partially salty water where a river meets the sea), produces a toxin that causes massive watery diarrhea that may cause fatal dehydration and loss of electrolytes
|
|
|
Chlamydia trachomatis
|
an obligate intracellular parasite that is transmitted by sexual contact, tiny cells that can absorb ATP from the host cell, not transmitted by ticks or lice, causes a very common form of STD, a leading cause of pelvic inflammatory disease, can also infect the eye
|
|
|
Yersinia pestis
|
causative agent of bubonic plague, causes an intestinal infection in fleas, in mammals it is an intracellular parasite that causes a blood infection centered in and around the lymph nodes, cause of the Black Death in the 14th century
