In Africa, a number of wildlife hosts have been identified as carriers, including the banded mongoose, Egyptian fox, Rusa deer, and shrews. Scientists at the U.S. Department of Agriculture USDA have found that a commercial vaccine is effective against leptospirosis in cattle. from 15 cows in each of 44 dairy herds from four different regions of the U.S. Overall, at least one infected cow was detected in 59% of the herds tested and, in most cases, serologic results indicated that the likely infecting serovar was Hardjo.

For vaccination of healthy cattle and swine in areas where the serotypes named are known to be prevalent. Dosage and Administration Shake well. Aseptically inject 2.0 mL subcutaneously or intramuscularly. For swine, a second dose should be administered 2-4 weeks later. Cows seldom abort in subsequent pregnancies, and heifers are often exposed to endemic areas before breeding age in an effort to prevent abortions.

Leptospirosis often shortened to lepto is an infectious disease caused by bacteria. Dogs can catch lepto by coming into contact with urine from an infected animal or from contaminated water. Rats can carry lepto and are a particular risk for dogs that like hunting and spending time in water. Leptospirosis may occur in two phases: After the first phase with fever, chills, headache, muscle aches, vomiting, or diarrhea the patient may recover for a time but become ill again. If a second phase occurs, it is more severe; the person may have kidney or liver failure or meningitis.

Leptospirosis is a widespread and potentially fatal zoonosis that is endemic in many tropical regions and causes large epidemics after heavy rainfall and flooding. Infection results from direct or indirect exposure to infected reservoir host animals that carry the pathogen in their renal tubules and shed pathogenic leptospires in their urine. Lepto has been diagnosed in all types of dogs. All breeds and sizes of dogs are at risk. Lepto can be a very serious disease and can be fatal if not diagnosed and treated early.
