Burkholderia cepacia complex
2011-04-14 15:49:49

Burkholderia cepacia complex (BCC), is a group of catalase-producing, non-lactose-fermenting Gram-negative bacteria composed of at least nine different species. It is an important human pathogen that often causes pneumonia in immunocompromised individuals with underlying lung disease. They are typically found in water and soil and can survive for prolonged periods in moist environments....

Bordetella pertussis
2011-04-14 15:37:44

Bordetella pertussis is a Gram-negative, aerobic coccobacillus of the genus Bordetella. It is the causative agent of pertussis or whooping cough and it is non-motile. There is no zoonotic reservoir thus humans are the only hosts. Bacterium is spread by coughing and by nasal dripping after an incubation period of 7 to 14 days. Pertussis is an infection of the respiratory system and...

Bartonella henselae
2011-04-14 15:18:05

Bartonella henselae is a proteobacterium that can cause bacteremia, endocarditis, bacillary angiomatosis, and peliosis hepatis. It is a causative agent of cat-scratch disease which occurs after a cat bite or scratch. The disease is characterized by swelling of the lymph nodes and fever. B. henselae can cause Peliosis hepatic which may develop with cutaneous bacillary angiomatosis or...

Bacillus subtilis
2011-04-14 15:10:21

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though...

Bacillus cereus
2011-04-14 15:02:33

Bacillus cereus is an endemic, soil-dwelling, Gram-positive, rod-shaped, beta hemolytic bacterium. Some are harmful to humans while other strains are beneficial as probiotics for animals. They are aerobes and can produce protective endospores. B. cereus competes with other microorganisms such as Salmonella and Campylobacter in the gut. In food animals harmless strains of B. cereus are used...

Bacillus anthracis
2011-04-14 14:43:25

Bacillus anthracis is a Gram-positive spore-forming, rod-shaped bacterium, with a width of 1-1.2µm and a length of 3-5µm. It can grow in aerobic or anaerobic conditions. It is the only known bacterium to synthesize a protein capsule and the only pathogenic bacterium to carry its own adenylyl cyclase virulence factor. They form oval spores located centrally in a non-swollen sporangium....

Actinomyces israelii
2011-04-14 13:54:22

Actinomyces israelii is a species of Actinomyces and is sometimes known as the "most misdiagnosed disease" since it is often confused with neoplasms. It is a colonizer of the vagina, colon, and mouth. Infection happens through breach of the mucosal barrier during various procedures, aspiration, or pathologies such as diverticulitis. The chronic phase is also known as the classic phase due to...

Acinetobacter baumannii
2011-04-14 13:29:59

Acinetobacter baumannii is a species of pathogenic bacteria that is resistant to most antibiotics. Some think the disease is killing tens of thousands of U.S. hospital patients each year due to its resistance to drug treatment. It can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body. It forms opportunistic infections including reports of...

Yellow Fever
2011-03-04 17:38:30

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa....

Strawberry vein banding virus
2011-03-03 21:36:56

Strawberry vein banding virus (SVBV) is a plant pathogenic virus and a member of the family Caulimoviridae. It was first described by Frazier after differential aphid transmission to susceptible wild strawberries. He identified suitable virus indicators and demonstrated virus transmission by various aphids, dodder, and grafting. He also established the inability of the virus to transmit via...
