In the present world, information technology continues to play an important role in health-care decisions, training, and public health informatics and especially among health practitioners who work directly to serve members of the public. The health and the well-being of Canadian citizens is particularly vital and is best dealt with by understanding the determinants of the disease, how it spreads from one Canadian to another and from community to community. As Flicker et al. (2004) observes, a man’s ill health and health status of the society is affected by environmental factors and lifestyle. This assignment is an examination ...

Human Immunodeficiency Virus (HIV) affects the immune system thereby weakening the body’s defense system by destroying white blood cells referred to as CD4+ cells(CDC, 2016). These cells are responsible for protecting the body against diseases. In the event that a significant number of these cells are destroyed, the susceptibility of the body to attacks by illnesses increases resulting to a more weakened immune system. However, by an individual having HIV, it does not automatically translate to them having AIDS (CDC, 2016). It takes quite a long time for the condition to progress from a virus to AIDS ...

Pathogenic and Non-pathogenic Organisms

Similarities in both organisms include the fact that both organisms are non-sporulating. Although, not the only metabolite, Salmonella enterica can produce lactate as one of its metabolite while Lactococcus lactis produces lactate. Both organisms are anaerobes, feeding by fermenting substrates (PHAC, 2010). Salmonella enterica ferments glucose while Lactococcus lactis ferments milk. Salmonella enterica is different from Lactococcus enterica in several ways. From gram staining, Salmonella enterica is a gram-positive organism while Lactococcus lactis is a gram-negative organism. At the level of feeding, Salmonella enterica feeds on a wide range of carbohydrates (PHAC, 2010). It is a heterofermentative organism whereas Lactococcus lactis is a ...

Pathogenic and Non-pathogenic Organisms

Salmonella enterica is a gram-negative rod, which flagellated. It is a member of the enteriobacteriaceae family and it has six subspecies. The bacteria usually reside in poikilothermic animals (PHAC, 2010). The bacteria has various serotypes which are characterized by surface antigens it includes the H antigen which is a flagellar antigen, the O antigen which is the Oligosaccharide antigen and the Vi antigen which is the polysaccharide antigen. Salmonella enterica is a facultative anaerobic organism. it is a motile, non-sporulating rod. the organism is a glucose and mannose fermenter. it does not produce gas and does not ferment lactose or sucrose. Most salmonellae produce Hydrogen ...
