1. if you used information from two different data sources, the number of cases of bacterial infections were obtained from the local health department, while the data regarding the number and types of fish products sold at local stores were obtained from the epiland fishing and wild game office. what type of epidemiological study would it be if you used two different types of information to test whether the consumption of fish products from epiland lake are associated with a higher risk of bacterial infections? 2. list two potential epidemiologic study types that would be suitable if all of the data came from the same source (i.e. one study) and it was used to test whether the consumption of fish products from the epiland lake are associated with a higher risk of bacterial infections?

Bacterial infections have a large impact on public health. Disease can occur at anybody site and can be caused by the organism itself or by the body's response to its presence. Bacteria are transmitted to humans through air, water, food, or living vectors

In order to know more about the bacteria and its pathogenicity, we perform gram staining. Pathogenicity is the ability of a bacteria or virus or any microorganism to cause the disease in an individual.

Gram staining of a bacteria gives the idea of how deadly the bacteria or the virus is. The principal modes of transmission of bacterial infection are contact, airborne, droplet, vectors, and vehicular. Preventive measures have a dramatic impact on morbidity and mortality. Such measures include water treatment, immunization of animals and humans, personal hygiene measures, and safer sex practices. Bacterial resistance to antibiotics is a growing concern mandating their prudent use.
