malaria and chicken pox. Symptoms of systemic infections include; fever‚ chills‚ weakness and aching joints. The chain of infection begins with a pathogen. The pathogen needs the right environment to enable them to grow. They need a route of transmission and a portal of entry. They then begin to multiply and make the host feel ill‚ then some of the pathogens will now exit the body and the chain begins again. Infections are caused by microbes which are found everywhere such as dust‚ homes‚ animals

Bordetella pertussis is a gram-negative coccobacillus bacterium‚ which causes whooping cough in humans (1‚ 41). The bacterium is spread by air borne particles or mucus droplets and is highly contagious. Although there is no known reservoir for the pathogen humans can often be asymptomatic‚ due to vaccination or immunity‚ and

How Are Infections Spread? Alicia Todd University of Mobile How Are Infections Spread? According to Lynch‚ Elmore and Morgan (2012)‚ millions of people die each year from infectious diseases such as influenza‚ malaria‚ tuberculosis‚ and acquired immunodeficiency syndrome (p. 245). Everything we eat‚ breathe‚ or touch throughout the day puts us at risk for developing an infection. Knowing how infections are spread will decrease these risks and is crucial for overall health. No matter how hard one

system is made up of different cells and mechanisms that are used to defend your body against agents that cause disease called pathogens. The immune system can be divided into two sections: the innate immune system and the adaptive immune system. The innate immune system provides a defense that is active immediately upon infection and is the same whether or not the pathogen has been encountered previously. It may include barriers that protect your body such as skin and mucous membranes‚ phagocytic

The macrophages are attracted to invading pathogens by chemicals. They ingest the pathogen and break it down into smaller pieces. They then put pieces of the pathogens outer membrane that contains the pathogens antigens onto its surface membrane. It is now called an antigen presenting cell. Each antigen has a specific shape.
