Parasitic Infections Humans And Infectious Diseases Essay

When reflecting on the history of the human species, it is said that the narrative of mankind and infectious diseases are intertwined. For centuries, humans have been exposed to a seemingly infinite amount of contagions. Many viruses, bacteria, and fungi have plagued human beings for ages and have eradicated populations thousands at a time. Through medical innovations and the advancement of scientific knowledge, humans have been able to combat disease and disease-carrying vectors. Through proper hygiene, antibiotics and vaccinations humans have been able to control and eliminate many viruses and bacteria. It would seem that with the growing amount of medical knowledge, that infections would be less common, but this is not the case. Not only are humans threatened by viral and bacterial infections, there are various parasites that also invade the human body. Parasitic infections are common in underdeveloped countries and are a prominent threat in rural areas. Though parasitic infections are known to happen in well-developed countries such as the United States. Contaminated water supplies, contact with infected animals, and improperly stored and cooked food can lead to parasitic infections. Parasites like tapeworms, protozoa, flukes, and nematodes can infect humans, causing serious health issues. These parasites enter through various parts of the body, and then live and reproduce in certain organs. Though there are many points of entry into the human body, most parasites enterShow MoreRelated infectious diseases Essay672 Words   |  3 Pagesand death from infectious diseases are particularly tragic because they are preventable and treatable. Not surprisingly, the poorest and most vulnerable are the most severely affected by infectious disease. Infectious diseases are a major cause of death, disability and social and economic turmoil for millions around the world. Poverty stricken countries lack access to health care.

Parasitology is the study of parasitic organisms that cause disease within humans. Parasites are defined as organisms that live in or on another organism and uses its resources. The major groups of parasitic organisms studied and observed in the clinical laboratory are helminths, protozoa, and arthropods. Helminths are worm parasites and this group contains the parasitic subgroups nematodes, cestodes and trematodes. Nematodes areRead MoreAntimicrobial Resistance, Resistant No socomial Pathogens and Molecular Diagnosis of Emerging Infectious Diseases1624 Words   |  7 Pagescause infectious diseases depending on their virulence; this was first realised when Louis Pasteur discovered microbes contaminated wine, causing it to go sour. He wondered how microbes affected humans; however it was Robert Koch that linked the contamination of microbes to the cause of infectious diseases. Between them they discovered and identified many of the microbes that caused diseases. Bacteria, Fungi, Virus and protozoan are all agents that cause infectious diseases. Infectious diseases canRead MorePuerto Rico Essay841 Words   |  4 PagesPuerto Rico is now facing yet another challenge of bacterial contamination due to lack of clean water and resources.

This stress reaction directly affects the hypothalamus and pituitary peptides through the sympathetic branch of the autonomic nervous system. Some of these stressors might be life events, anxiety, and excitements. The human body reacts externally or internally in the way of physiological responses. When we experience one of these stressors the physiological responses job is to prepare the body to deal either by adapting to it or simply surviving it. This can promote aRead MoreStrongyloides Stercoralis : A Closer Look1478 Words   |  6 Pagesstercoralis: A Closer Look in Threadworms Introduction Strongyloides stercoralis is a parasitic intestinal nematode that primarily infects humans; however, other Strongyloides species can also infect animals such as birds, reptiles, amphibians, and other primates.1 S. stercoralis is known to cause strongyloidiasis to humans.1 Infection with S. stercoralis can be a lifelong issue and can result in a chronic disease with varying symptoms.2 Although S. stercoralis is estimated to infect 30-100 millionRead MoreHow Human Toxoplasmosis Is Considered A Major Health Problem1142 Words   |  5 PagesHuman toxoplasmosis is considered a major health problem among various Egyptian patients with a prevalence of 59.1% among ocular patients (El-Sayed and Ismail 2012), 56.7% among schizophrenia patients, 40% among patients with depressive disorder (El-Sayed et al. 2012) and 33.67% among blood donors (El-Sayed et al. 2016). Thus, this study determined the relationship between Toxoplasma infection and Egyptian RA patients by detecting IgM and IgG antibo dies in blood samples of the patients compared withRead MoreSexually Transmitted Infections ( Stis )767 Words   |  4 PagesSexually transmitted infections (STIs) are caused by more than 25 infectious pathogens transmitted from one person to the other during anal, vaginal as well as oral intercourse. More so, infected pregnant women can transmit STIs to infants in utero, during birth, or through breastfeeding. The most common STIs in the U.S. include chlamydia, gonorrhea, genital herpes, human papillomavirus, trichomoniasis, and bacterial vaginosis (Buttaro, Trybulski, Bailey, Sandberg-Cook, 2013).
