infectious avian nephritis

caused by a picornavirus this disease of young chickens causes a transient unremarkable disease with lesions appearing in the kidney.

infectious bovine cervicovaginitis

thought to be due to a herpesvirus-4 infection, transmitted by coitus, causing sterility in a high percentage of cows and some bulls. Recorded only in South Africa. Called also epivag.

infectious bovine keratoconjunctivitis

the common infectious keratitis of cattle caused by Moraxella bovis with solar radiation, dust and face flies as contributing factors.. It occurs as outbreaks, characterized by ocular discharge, blepharospasm and pain. Underrunning of the conjunctiva leads to complications in a few cases. Called also pinkeye, blight, New Forest disease.

infectious bovine meningoencephalomyelitis

see hemophilosis.

infectious bovine rhinotracheitis (IBR)

a highly infectious disease of cattle, particularly when crowded together as in feedlots, caused by bovine herpesvirus 1 and characterized by nasal discharge, rhinitis, tracheitis, conjunctivitis, fever and a short course unless complicated by other infections, particularly those leading to pneumonia. Less common forms of the disease include encephalitis in calves and a systemic infection in neonates, manifested by oral erosions and diarrhea. Infectious pustular vulvovaginitis is also caused by this virus. Called also rednose.

infectious laryngotracheitis (ILT)

a highly infectious disease of birds of all ages caused by avian herpesvirus 1 and characterized by a very rapid spread of respiratory distress, the signs including gasping, respiratory gurgling and rattling, and death often from asphyxiation because of massive pseudomembrane formation in the trachea. The mortality rate may be as high as 70%.

infectious necrotic hepatitis

an acute toxemia of cattle, sheep and pigs caused by Clostridium novyi which elaborates a toxin in necrotic infarcts in the liver. These infarcts are caused usually by larvae of Fasciola hepatica. Many affected animals are found dead. Clinical findings include severe depression, hypothermia and muffling of heart sounds. Called also black disease.

infectious pancreatic necrosis of fish

a disease of salmonids caused by a group of related birnaviruses. It is characterized by hemorrhages and anemia, and spiral swimming and abdominal distention in fry.

severe disease of Atlantic salmon, reported only, to date, from Norway; characterized by liver necrosis caused by an unidentified virus.

a septicemic disease of young ducks caused by Riemerellaanatipestifer and characterized by torticollis, head tremor, loss of balance and a high mortality rate.

infectious sinusitis

a contagious disease of turkeys caused by Mycoplasma gallisepticum. The same infection also causes chronic respiratory disease of chickens. The disease in turkeys is characterized by swelling of the infraorbital sinuses, which are filled with thick exudate. The course is chronic and the death rate low but there is severe loss of condition and damage to the respiratory tract.

Patient discussion about infectious hematopoietic necrosis of fish.

Q. Is psoriasis infectious? Last week I and my friends from high-school went to the pool. One of my friend has psoriasis on his back, and when the lifeguard noticed it he asked him to leave the pool because he has skin disease that may spread to the other people swimming in the pool. We told him it is psoriasis and not some fungus, but he told us that psoriasis is also infectious. Is that true? Can psoriasis infect people who come in touch with people with psoriasis? Can I go swimming with him or should be more cautious?

A. I’m sorry to hear about your friend’s bad experience. People can be so mean and bad, and it’s even worse when they think they’re right when they behave like that. Your friend can’t make you have psoriasis, no matter how much he’ll touch you, so you can go swimming with him with out any worries.

Q. Can I catch pneumonia, if I go outside with wet hair? My Mother used to tell me when I was a kid that if I go outside with wet hair, I will catch pneumonia. Is this true?

A. IF YOUR WET WATER REMOVES MORE HEAT FROM THE BODY FASTER THAN WHEN YOUR DRY ALSO CONSIDER THAT HEAT RISES WE LOSE MOST OF THE TOP OF OUR HEADS WHEN YOU ADD WATER YOU DRAMATICLY LOWER YOUR TEMPERATURE ON YOUR HEAD AND ALSO CONSIDER THAT IF YOUR MOVING FROM A COLD PLACE TO A WARM PLACE SEVERAL TIMES A DAY LIKE A FREEZER ON A HOT SUMMER DAY OR INDOORS TO OUT DOORS IN THE WINTER TIME 20 MINUTE INTERVALS I WILL SAY YES YOU CAN CATCH COLD AN GET THE SNIFFLES, COUGH AND OR SORE THROUGHT BUT I DO AGREE THAT YOU WON'T NECISARLY GET PENOMNIA FROM JUST WET HAIR ALONE THERES MANY MORE FACTORS FOR THAT.

Q. Are cold sores contagious? My boyfriend has cold sores on his mouth. Can I catch it from him? If so, how can I prevent catching it?

A. The virus that causes cold sores is known as the herpes simplex virus (HSV). There are two types of HSV, type I and type II. Cold sores are usually caused by type I. Herpes simplex infections are contagious. You can catch the virus by kissing your boyfriend or having other close contact with his sores or even from having contact with other parts of his skin that appear normal but are in fact shedding the virus. People are most contagious when they have active blister-like sores. Once the blisters have dried and crusted over (within a few days), the risk of contagion is significantly lessened. Therefore, it is best that you don't come in physical contact while he has the cold sores, since he is contagious. However, a person infected with HSV can pass it on to another person even when a cold sore is not present. This is because the virus is sometimes shed in saliva even when sores are not present.
