1.7 Disease transmitted by animals are:

Psittacosis: Bird owners, pet shop employees, and veterinarians. Infection is acquired by inhaling dried secretions from infected birds. Pet birds (parrots, parakeets, macaws, and cockatiels) and poultry (turkeys and ducks) are most frequently involved in transmission to humans. Chlamydia psittaci, is the responsible agent. Treatment is by Doxycycline.

Echinococcus: Transmitted by petting or handling household cats and dogs infected with the E. multilocularis tapeworm. These pets may shed the tapeworm eggs in their stool, and their fur may be contaminated. Some dogs "scent roll" in foreign material (such as wild animal feces) and may become contaminated this way. In North America E. multilocularis is found primarily in the north central region from eastern Montana to central Ohio, as well as Alaska and Canada.
Diagnosis is made using ultrasonography and/or other imaging techniques supported by positive serologic tests. 
Surgery is the most common form of treatment for AHD, although removal of the parasite mass is not usually 100 % effective. After surgery, medication may be necessary to keep the cyst from growing back.

Brucella: Brucellosis is a zoonotic disease and occurs most often in slaughter-house workers, veterinarians, and farmers. In this country, 25% of all cases are associated with one slaughter house in North Carolina, and the individuals who contract the disease are mostly poor and can ill-afford to be chronically debilitated as can occur with Brucellosis. Caused by Brucella abortus or B. melitensis or B. suis.
Brucellosis in humans is a systemic disease that has an acute or insidious onset; signs and symptoms of the disease include continued, intermittent, or irregular fever of variable duration; headache; weakness; profuse sweaty chills; arthralgia; depression; weight loss; and generalized aches. 
Veterinarians and other animal health-care personnel should be made aware of the possible risk for infection. Exposure of farm and veterinary personnel to infected calves or placentas is another potential source of human infection.
Diagnosis is made using serology for antibodies against Brucella. 
A combination antibiotic therapy using Doxycycline and Rifampin or an Aminoglycoside is used to treat and prevent relapse of infection

Cat scratch disease: Bartonella henselae. It is caused most commonly by scratch of a kitten. CSD is typically a benign and self-limited illness lasting 6 to 12 weeks in the absence of antibiotic therapy. Regional lymphadenopathy (axillary, head and neck, inguinal) is the predominant clinical feature of CSD; affected nodes are often tender and occasionally suppurate. Treatment is usually unnecessary. Perinaud's oculoglandular is an unusual syndrome due to CSD which manifests as conjunctival granuloma, peri-auricular lymphadenopathy, and non-suppurative conjunctivitis.

Orf: Also known as milker's nodule. Caused by the Orf virus belonging to parapox virus family, This is a  disease that affects the skin with a weeping nodule that is reddish brown. It may have a central depression. The disease is typically self limiting and lasts 3-6 weeks. One must ask about sheep or goat exposure.

Hantavirus: Hantavirus is carried by rodents, especially the deer mouse. It is transmitted via their droppings. It causes Hantavirus pulmonary syndrome. This is a syndrome that starts off like an ordinary viral syndrome but progresses rapidly to multilobar pneumonia necessitating hospitalization and frequently - mechanical ventilation. Lab studies giving a clue to this include thrombocytopenia, atypical lymphocytes and rapidly changing, multilobar pulmonary infiltrates.

	Borrelia: Causes Lyme Disease. Transmitted by the bite of deer ticks Ixodes, it is commonly an insidious disease. Typically found in the northeastern and north-central United States.

Dog bite: Pasteurella multocida. Only 5% of dog bites get infected as opposed to cat bites (over 80% get infected). Co-Amoxiclav (Augmentin)is Rx of choice.

Cat bite: Over 80% of cat bites will get infected. Treatment is almost mandatory. Commonest bacteria responsible for infection is Pasteurella multocida. Rx of choice is Co-Amoxiclav. Alternate treatment is Cefuroxime axetil. Do not use Cephalexin.

Rabies: Bats are the commonest cause of transmission to humans in the United States - although skunks/raccoons may be the largest reservoir in wildlife of the US, they do not commonly bite humans to transmit the disease. There were NO cases of rabies in humans in the US in 1999.

Reptiles hydromonas:
