Dog Virus and Bacteria in Dogs Viruses are the simplest organisms known to man... and dogs. They're either constituted by DNA or by RNA – never both simultaneously- and protected with a cover of protein, which parasite other cells to reproduce. Their size is very variable, but either when some tend to grow bigger that bacteria, most are much smaller than these. Their main activity is a process of replication that is created after the introduction of their nucleic acid in the host cells, so it can be said that this activity is strictly bonded with a purely infectious activity. Most viruses known cause diseases, varying in seriousness from one to the next, and they attack both men and animals alike. Bacteria are also unicellular organisms, with no chlorophyll or nucleus, but with chromatin grains dispersed in the protoplasm, provided with flagella that helps them move around in the liquid they live in. Many species live in sweet or salted waters and some also live in organic substances, most of which are dead or in the process of putrefaction, while others are parasites of hosts, let them be animals or humans. Happily for dogs, there are a number of vaccines available for them to prevent the most serious diseases from spreading around.Types of Dog vaccines: Actually, and due to the major scientific advances, there are several different types of vaccines that have ended with the risks of adverse reactions to the administration of the vaccine, which wasn't at all unusual before. - Attenuated vaccines. The germs are modified to reduce and attenuate their infective capacity maintaining, nevertheless, their capacity to stimulate the formation of the necessary antibodies. One dose is usually enough, even when possible collateral effects that some of them tend to produce can be avoided using other alternatives. To ensure an optimal protection of the animal, one dose will suffice for the first time, followed by the revaccination, which should be done once, every two or every three years, depending on each case.
- Inactive vaccines. Composed by viruses or bacteria that have been treated ("dead") with heat or chemical agents such as formalin. Incapable of multiplying in the animal's organism, they stimulate the production of the necessary antibodies. For an optimal protection, the administration usually is composed of two doses in the first instance, with some days of separation between each, and later the yearly revaccination, depending on the veterinarian's criteria.
