Not directly infected animals act like reserving of parasites, when the vinchucas bite them they get infected and in posterior bites the infection can be transmitted to an animals or healthy person, completing, in this way, the cycle. Birds can not be reserving of parasites. There are 3 clinical stages: acute, indeterminate and chronic. These stages have different clinical evolutional, anatomical and pathological characters.

So far, animals that appear affected by Borrefia burgdorferi are dogs and horses. Studies are underway in cats and cattle. Some animals have shown limb joint disease similar to that described in dogs.

According to experts, there's no evidence that CWD can be naturally transmitted to domestic livestock. Chronic wasting disease is similar in some respects to two known livestock diseases: Scrapie, which affects domestic sheep and goats worldwide and has been recognized for over 200 years; and Bovine Spongiform Encephalopathy (BSE), which is a more recent disease of cattle in the United Kingdom.

Johne's disease typically enters a herd or flock of animals when an infected, but healthy-looking, animal is purchased. The infection then spreads to other animals, often without the owner's being aware of it. Eventually, perhaps after several years, the owner recognizes signs of the disease in a number of animals. Individual animals get infected by close contact with other infected animals, that shed the bacterium in their manure.

There are three common ways to test animals for Johne's disease: culture of fecal samples, DNA probe on fecal samples, and blood tests for antibodies to M. paratuberculosis. It is best to consult with your local veterinarian about testing. (Because testing strategies are somewhat different for each animal species, visitors to this site are advised to seek detailed information by first selecting an animal species and then choosing "Diagnosis" from the menu on the left).

Johne's (pronounced "Yo-nees") disease is a contagious bacterial disease of the intestinal tract. A German veterinarian first described the disease in a dairy cow in 1895; his name is used as the common name for the disease. The disease is also called paratuberculosis. Visit the history page for more details. Johne's disease occurs in a wide variety of animals, but most often in ruminants. Ruminants are hoofed mammals that chew their cud and have a 3-4 chambered stomach.

There have been no reports of H5N1 causing illness to humans exposed to infected animals other than birds. Current data indicates that 9 species of mammals have contracted the H5N1 virus including domestic and exotic cats and ferrets. However, the ability of infected mammals to transmit the H5N1 virus to humans is still under research. Heat is a good way to kill the virus, so properly cooked internal organs should be safe (see Question #13).

Mosquito bites can transmit diseases, such as Malaria, Dengue and West Nile Virus, so authorities in many areas take actions to diminish mosquito populations. This is still usually done using regular pesticides, despite the fact that organic and environmentally-friendly methods, such as those developed by Westham Innovations, are currently available,

IBD and gastrointestinal disorders have been diagnosed in cats and dogs. If you would like more information, there are a couple of articles at the "Official Site of Veterinary Medicine in Canada".

The best way to avoid this chronic infectious disease is to be as certain as possible that animals brought into the herd are not infected with M. paratuberculosis. This is not always easy. Laboratory tests for cattle are more widely available than for sheep, goats or zoo animals. Still, some type of test is available for every animal.

It is a fact that in the USA today, literally hundreds, and perhaps thousands of vaccinated cats and dogs are still contracting the diseases they were vaccinated against. Some term this 'vaccine failure,' although it is more likely a failure of the immune system to respond than a problem with the vaccine itself.

this time it is not known, though research is underway. Mosquitoes, deer flies, and horse flies have been shown to harbor the spirochete, as have other species of ticks such as the Lone Star tick (Arriblyorrima americanum), which occurs in New Jersey and in many of the southern states. There is little available evidence, however, on their efficiency at transmitting Borrefia burgdorferi.

The two ticks now known to transmit Lyme in the US are Ixodes scapularis (NE and S US-- formerly called I. dammini) whose common name is the deer tick; and I. pacificus (common name- western black-legged tick) in the W US including all of the W coast states, plus Arizona, CO and Nevada. However, what is important for transmission in any locale is 1) the availability of animal reservoirs--deer and small mammals--the contact with domestic animals and humans is incidental to that.

Apart from the FAD (Allergic dermatitis), which is an allergy to flea saliva and/or faeces, there are a number of other diseases transmitted by the flea.The flea is an intermediary host of Dipylidium Caninum, known as Tapeworm, which is a cat’s and dog’s intestine worm (cestode). The flea larvae ingests the eggs of this cestode, which matures into worm-larvae. The worm-larvae is the infecting stage hosted by the adult flea.

No. Most mosquitoes do not transmit disease. While there are about 65 different species of mosquitoes in New York State, only certain species have been associated with West Nile Virus in New York State.
