Although there are four forms of zoonosis, two of them are much more spread out and available for contraction. The first one is viral, since transmission through air is much more rapid and fast. Zoonotic viral infection can become a real problem if well established in the area and even worse if adapted for human to human transmission. That being said, it might become an endemic problem in some regions or populations if not treated. And if not properly controlled it might turn into a pandemic situation spreading throughout the whole country and nearby counties or even worldwide. The second one is bacteria, which does not spread as rapidly as viral but still have a significant impact on the animal and human populations. It can cause foodborne and waterborne contaminations.

- Zoonosis are infectious diseases that have been transmitted between animals and humans or in its advanced stage from human to human. It also can be transmitted from human to animal, when that happens it is called reverse zoonosis. Emerging zoonosis are infectious diseases that are newly recognized or newly evolved while re-emergence zoonosis have occurred previously but have more recently shown an increase in incidence or expansion into a new geographic, host or vector range. The concept of ‘emerging zoonotic diseases’ developed as health scientists documented and tried to explain the apparent abrupt rise in the number of new and important infectious diseases over the past two decades (Bengi...

- At the San Francisco zoo in California a young girl was killed by a tiger who had escaped his low-quality enclosure; the tiger was shot dead on the spot.

- Scooby Doo. Toto. Snoopy. We all know and love these dogs as characters and as sidekicks (and best friends) to their human counterparts. Known for their incredible ability to bond with humans and their generally unconditionally loving personalities, dogs are arguably the most beloved animal in modern culture.

- Campylobacter jejuni, a motile, curved S or spiral shaped Gram negative rod, microaerophilic, is a common cause of human gastrointestinal infection (Garvis et al., 1996). Drinking water may be the common reservoir causing campylobacter infection in human and animals, including wild birds and poultry (Kapperud et al., 2003). Under coocked chicken seems to be linked with a great proportion of campylobacteriosis (Phillips et al., 1997). Poor hygienic conditions and the existence of animals in the house are also responsible for campylobacter infection (Rao et al., 2001).... [tags: bacteria, diarrhea, children]
