Pathogen

A range of bacterial communities including commensals and pathogens colonize nasopharynx. The pharyngeal inhabitant Streptococcus pyogenes (group A streptococcus (GAS)) an adapted human pathogen is a common colonizer of mucous of the mouth, nose and pharynx, is among the many pathogens that most often colonize their host asymptomatically and only occasionally cause disease. Local pharyngeal infection of GAS is manifested as pharyngitis and spread from the local site can cause the systemic…

bacterial pathogens such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogenes…

deliverance of preformed antibodies. 1. Naturally acquired active immunity occurs when an individual is exposed to a live pathogen of which enters the body by a natural route, such as an infection, and a primary immune response develops to produce antibodies against the antigen. As a result, memory cells are retained by the individual’s immune system to provide immunity against the same pathogen in the future. Consider the following as an example. One day my brother came home from pre-school…

Introduction The human body is populated by a large aggregate of microbes on the skin as well as many mucosal surfaces. They are composed of mainly bacteria, fungi, and protozoa. These commensal microorganisms live in the human body in symbiosis. Microbiota play a functional role in the health and disease of an individual. Roughly there are around 1012 bacteria found on the skin, primarily staphylococci and corynebacteria, and 1010 found in the mouth, primarily, streptococci, lactobacilli.1 But…

pneumonia. Bronchoalveolar lavage (BAL) may also be used to assist in the diagnosis of pneumonia (Scholte, 2014). BAL removes fluid from a part of the lungs and helps identify any respiratory pathogens within the respiratory tract. Secretions from the bronchi…

daily. This is how humans become exposed to microbial pathogens. The ocean and estuarine ecosystems influence the way humans are exposed to the microbial pathogens. These pathogens include, marine-indigenous pathogens and pathogens that are introduced via pollution. The pathogens that are found with marine animals are phytoplankton, zooplankton, sediments and detritus. There are environment factors that go into multiplying and keeping the pathogens alive. These factors include: salinity,…

antibacterial options currently available. Throughout the world, many Gram-positive and Gram-negative pathogens are growing more resistant to antibiotics currently on the market. The goal of this journal article is to raise awareness for the global antibiotic crisis and to hopefully encourage the community and legislative to raise funds in order to increase antibiotic production. The “ESKAPE” pathogens that are currently causing the majority of infections and are resistant to current antibiotics…

prevent disease and infection. The two main ways to prevent the spread of disease is to use hand sanitizers, or to wash your hands. Many say that hand sanitizers kill the pathogens, or “microorganisms that causes disease that accumulate on your hands” (Krystine). Also, people say that hand washing is the best way to prevent pathogens from spreading, which is true. In the past, before people were educated on the risk factors of not being sanitary, sickness spread. Surgeons, nurses, and doctors…

everything in its path before they attack Pac-Man; the body’s defense system works in much the same way to keep us alive. Our immune system, which is a collection of organs, tissues, and cells, works day and night to protect our body from attacks that pathogens, viruses and bacteria, try to use…

Infection is called as a pathogen invades a human or an animal and grows in the organism, and the expression of symptoms caused by this infection is called infectious disease. Infectious diseases have no symptoms at all, but it has incurable infection that cause only immunity, and those that cause symptoms. Sometimes they are synonymous with infectious diseases. Infectious is a disease that easily migrates to many people. In Europe, there are many programs to cure and prevent the infectious…
