Burkholderia mallei
2011-04-14 16:00:01

Burkholderia mallei is a gram-negative bipolar aerobic bacterium. The human and animal pathogen causes Glanders. The Latin name of this disease gave name to the causative agent species. It is related to B. pseudomallei although the bacterium is nonmotile. The bacterium can be eliminated through numerous disinfectants including benzalkonium chloride, iodine, mercuric chloride, potassium...

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 bronchiseptica
2011-04-14 15:28:20

Bordetella bronchiseptica is a small, gram-negative, rod-shaped bacterium of the genus Bordetella. It can cause bronchitis although it rarely infects humans. It is closely related to pertussis which causes whooping cough and B. bronchiseptica can persist in the environment for extended periods. Humans are not natural carriers of B. bronchiseptica, which normally infects the respiratory...

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...

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...

Rubella Virus

Rubella virus is the cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy. Humans are the only known host of this virus. It is the only member of the genus of Rubivirus and belongs to the family of Togaviridae. Members of the Togaviridae family typically have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral...

Tobacco Ringspot Virus

Tobacco ringspot virus (TRSV) is a plant pathogenic virus in the plant virus family Comoviridae. It of the type species Comoviridae Genus Nepovirus. Nepoviruses are transmitted between plants by nematodes. It is easily transmitted by sap inoculation and transmission in seeds has been reported. IT was first observed in tobacco fields in Virginia in 1927. It is an isometric particle with a...

Poliovirus
2011-02-23 17:23:51

Poliovirus, the causative agent of poliomyelitis and a member of the family of Picornaviridae, is a human enterovirus. It is composed of an RNA genome that is a single-stranded positive-sense RNA. It was first isolate in 1909 and was published in 1981. It is one of the most well characterized viruses and has become a useful model system for understanding the biology of RNA viruses. It...

Phocine distemper virus
2011-02-23 17:16:23

Phocine distemper virus (PDV) is a pathogenic for pinniped species such as seals. Signs include labored breathing, fever, and nervous symptoms. It was first identified in 1988 as the cause of death of 18,000 harbour seals along the northern European coast. A PDV epidemic occurred again in 2002 along the North Sea coast resulted in the deaths of 21,700 seals. Numerous carnivorous mammal species...
