Influenza A virus subtype H1N1 particles. Digitally-colorized transmission electron micrograph. The surface proteins located on the surface of the virus particles are shown in black. This virus, first detected in 2009, belongs to the Orthomyxoviridae family and contains the glycoproteins haemagglutinin and neuraminidase, hence the H and the N in the subtype name. Some H1N1 strains cause infection in humans and others in pigs (Pig Flu, Swine Flu, Swine Influenza). Pig flu (Swine Influenza, Swine Flu) is a respiratory illness that occurs in pigs. Transmission of H1N1 from pigs to humans (Zoonosis) is not common and does not always lead to human illness. The virus can be infectious from human to human. Symptoms of this virus in people are similar to the regular flu which include fever, cough, sore throat, body aches, headache, chills and fatigue.

This bacteria causes the plague and affects humans as well as other animals. Infection by this facultative anaerobic, gram-negative, rod coccobacillus organism can take several clinical forms. The most common are bubonic , pneumonic and septicemic. All three forms have a high-mortality rate as evident from historical epidemics. This organism can be transmitted to humans by flea bites, contact with contaminated materials or infectious droplets. Today an infection without prompt and proper treatment can cause serious illness or death.
