Marfans Syndrome
2013-07-19 15:22:33

Marfan's syndrome is a genetic disorder of the connective tissue that causes excessively tall stature and long extremities. It is carried by the gene FBN1, which encodes the connective protein fibrillin-1, and is a dominant trait. The human genetic makeup contains a pair of FBN1 genes, so because of its dominance, inheriting one affected FBN1 gene from either parent will result in Marfan's...

Yersinia enterocolitica
2011-04-28 18:03:11

Yersinia enterocolitica is a species of gram-negative coccobacillus-shaped bacterium, belonging to the family Enterobacteriaceae. Infection from Yersinia enterocolitica causes the zoonotic disease yersiniosis. Most infected animals recover from the disease and become asymptomatic carriers. Acute infections lead to mild self-limiting entero-colitis or terminal ileitis in humans. Symptoms...

Helicobacter pylori
2011-04-15 15:38:47

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar...

Clostridium perfringens
2011-04-15 14:02:16

Clostridium perfringens (formerly known as C. welchii) is a Gram-positive, rod-shaped, anaerobic, spore-forming bacterium of the genus Clostridium. It is always present in nature and is a normal component of decaying vegetation, marine sediment, the intestinal tract of humans, other vertebrates, insects, and soil. It can be a human pathogen and also harmlessly ingested. Commonly it is...

Zucchini Yellow Mosaic Virus
2011-03-04 17:45:07

Zucchini Yellow Mosaic Virus (ZYMV) is an aphid-borne potyvirus and is regarded as a major pathogen of cucurbits. It affects pumpkins, squashes, vegetable marrows, courgettes, melons, watermelons, cucumbers, gherkins, and various gourds especially zucchinis. The effects are severe leaf mosaic, yellowing and eventually the leaves show "shoestring" symptoms. Fruits can become stunted, twisted...

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....

Polyomavirus
2011-02-23 17:31:48

Polyomavirus is the sole genus of viruses within the family Polyomaviridae. Ludwik Gross discovered the first polyomavirus, Murine polyomavirus, in 1963. Many polyomaviruses infect birds and mammals and have been extensively studied as tumor viruses in humans and animals. Polyomaviruses are DNA-based, small, and icosahedral in shape. They can potentially cause tumors and often persist as latent...

Orf
2011-01-12 16:45:59

Orf, an exanthemous disease, is caused by a parapox virus primarily occurring in sheep and goats. It has many other names including thistle disease, scabby mouth, and sheep pox. It can infect humans as well. It is a zoonotic disease meaning that humans contract the disease through direct contact with infected animals. Generally there are no systemic symptoms. The finger, hand, arm, face,...

Foot-and-mouth Disease
2011-01-12 16:40:04

Foot-and-mouth disease, FMD, is sometimes fatal and is highly contagious for cloven-hoofed animals. Along with hooved animals hedgehogs and elephants are susceptible to the disease as well. Llama and alpaca can develop mild symptoms but are resistant to the disease and don't pass it to other species. Mice, rats, and chickens have been infected artificially in a lab but it is not believed they...

Dengue Fever

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it...
