Common Types of Pathogens Viruses Bacteria Fungi Prions Protozoa . Human Intestinal Parasites. Salmonella are intestinal organisms transmitted to humans by fecal contamination of food and water. Pathogens include viruses, bacteria, fungi, and parasites that invade the body and can cause health issues. The types of pathogens (disease-causing organisms) which infect humans, plants, and other animals are amazingly diverse. • Human parasitology is the study of those organisms which parasitise humans • According to the very broad definition of parasitology, parasites should include the viruses, bacteria, fungi, protozoa and metazoa (multi-celled organisms) which infect their host species • However, for historical and other reasons the first three have been incorporated Most protist diseases in humans are caused by animal-like protists, or protozoa. Enteric and non-enteric diseases Ingestion of contaminated water Contact with contaminated water Complicated life cycles taking place in water and the human body with intermediate hosts. a. Caused to some specific factor, such as malfunctioning of some vital organ, deficiency of nutrients, etc. Aug 7, 2014 Parasites include,various protozoa and worms which may infect humans . This difference has important implications for control and prevention. Usually parasitic diseases are caused by endoparasites.

Several parasites have emerged as significant causes of foodborne and waterborne illness. intestinalis is the most prevalent parasitic cause of diarrhoea in the developed world, and this infection is also very common in developing countries. However, given the right conditions, staphylococci can cause superficial and systemic infections. Examples include rabies virus, Rift Valley fever virus, and Borrelia burgdorferi (the agent of Lyme disease). View and Download PowerPoint Presentations on COMMON PARASITIC DISEASES PPT. As parasite density in stool or body fluids may not be constant, the collection of repeated samples is often essential. The bulk of this program concentrates on those plant health problems that are caused by pathogenic microorganisms. includes three species which are common parasites of man, viz. E. Examples of parasites causing human illness are tapeworm (which causes digestive illness), ticks (which cause Lyme disease), and plasmodium (which causes malaria). Pathogens and parasites in food Bacteria -E. Parasitic pathogens in water. Parasitic Pathogens Affecting the CNS Mark F. , UNL Extension Food Specialist Parasitism. , Pseudoterranova spp. 3 Pathogens are considered to be “communicable” because “they have the ability to spread from one person to another by way of contaminated water and/or other vectors. Transmission of parasites such as giardia, hookworm, roundworm, and toxoplasmosis can be transmitted to humans from dogs, cats, and other animals . Below are some common parasites you might find in your game meat – and what you should do to prevent disease. Mark F.

The worms are not found in the U. Conventional Common questions about pets and parasites. The bacteria and viruses that cause the most illnesses, hospitalizations, and deaths in the United States are: Salmonella. 3 Pathogens spread by water leading to the spread of diseases. The Association of the British Pharmaceutical Industry states that four ways pathogens are spread are by droplet infection, direct contact, bodily fluids and vectors. In the adult stage, all species are obligate. However, a number of studies show that this 'asymptomatic infection' may also lead to development of other human pathologies. In some cases, the disease also affects the animal, but in other cases the animal is asymptomatic. In secondary hosts, the parasite becomes encysted in muscle and For many people, parasites are the stuff of nightmares. They feed mainly on blood and their mouthparts are armed with small backward-facing teeth to aid in attachment. Dwarf tapeworm is the most common human tapeworm in Australia. Pathogens Human Portals of exit: -Saliva for mumps -Mucous membranes pathogens may include: -Bacteria -Viruses -Fungi -Protozoa -Parasitic worms -Prions; 5. To eliminate these problems, a binomial system of nomenclature in which the scientific name consists of the genus and species is used. Fungi They are most commonly found as environmentally resistant spores and molds, but can cause disease in humans in the form of yeasts.

What is the difference between a virus and a parasite? Parasites are part of a large group of organisms called eukaryotes. Fleas, ticks, and mosquitoes are common biological vectors of disease. Socioeconomic factors increase the risk of a person being infected with soilborne diseases. Although common names frequently are used to describe parasitic organisms, these names may represent different . The importance of the subject is obvious; since the beginning of agriculture humans have had to endure major crop losses because of disease. Zoonoses can be caused by a range of disease pathogens such as viruses, bacteria, fungi and parasites; of 1,415 pathogens known to infect humans, 61% were Organism = Parasite or pathogen; Human = Host; Method of spread = Determine factors more common in disease group than healthy group (risk factors). : Share Your Word File Share Your PDF File Share Your PPT File. ” 3 The most common Hygiene - Viruses, Bacteria, and Parasites. Examples of endoparasites include flukes and tapeworms, while examples of ectoparasites include mosquitoes, fleas, Many species occur as free-living aquatic organisms whereas others live in insects and some vertebrates as symbiotes, commensals or parasites (several species cause major human diseases such as sleeping sickness, Chagas disease, kala azar and diarrhoea). cause disease in humans. 1-3,8,12,14,17 Examples of parasites causing human illness are tapeworm (which causes digestive illness), ticks (which cause lyme disease), and plasmodium (which causes malaria). e. Malaria, which is caused by a protozoan of the genus Plasmodium transmitted to humans by the bite of an anopheline mosquito, is an example of this interaction. They are single-celled living organisms and they need living human cells to survive. When I refer to intestinal parasites, I’m referring to tiny organisms, usually worms, that feed off of your nutrition. Explain the terms predator, parasite, parasitoid, and pathogen. but they are common worldwide. Felines are the definitive host and are infected primarily by the consumption of infected mammals and birds, which act as sec-ondary hosts. Some medicines are available to treat parasitic infections. Presentation Summary : Hydatid Disease After Humans consume the eggs passed by dogs the worms can form huge cysts in the body Toxoplasmosis How many have of you have heard that Parasitic Pathogens Affecting the CNS common T. Some livestock diseases are “zoonotic,” meaning that they cause illness in humans A second group of pathogens on “List B . Prevention is especially important. Source and finished drinking waters are vulnerable to microbial pathogen contamination from a variety of sources of human and animal The bacteria which cause foodborne illness in humans grow best at body temperature (98. If you are traveling, it's important to drink only water you know is safe. Among them, around 70 species of protozoan parasites and around 300 species of helminths are known to have human as their host and are then considered as pathogens for humans. Protozoan Disease # 7. - Many of the diseases and parasites/pathogens we have discussed are human parasites or zoonotic diseases for which we know the reservoir hosts and transmission. Pathogenic protozoa are referred to as parasites and cause a wide array of clinical diseases. Some protozoa are free-living, while others parasitize other organisms for their nutrients and life cycle. Sparganosis There are many different types of pathogens and many problems they cause. k. The group of bacteria known as staphylococcus, particularly Staphylococcus aureus, are one of the most common causes of human disease. AIDS. Tina M. 1 Ecologists Study Relationships 31.

They enter the body through the gastrointestinal Fungal diseases may also be called mycosis or mycotic diseases. Anthrax, HIV, Epstein-Barr virus, and the Zika virus, among many others are examples of pathogens that cause serious diseases. Immune responses differ between laboratory mice and humans. * Parasitic Organisms come The parasites grow and develop in the stomach of the mosquito and are injected into humans where they multiply in red blood cells. Actinomycosis is caused by infectious actinomycete species, often Actinomyces israelii, a soil dwelling species that is found in decaying organic matter (Roque 2010). worldwide: one of the most common human parasites; estimated to infect between 30–50% of the global population. MACRO-PARASITES. Infection / Transmission. Protozoa make us sick when they become human parasites. Examples include fungi, bacteria, viruses and sometimes nematodes. You have good bacteria in your gut, but some bacteria are pathogens and invade your system to cause diseases. The human mouth and intestines harbor over 400 different types of bacteria that produce some vitamins and ferment fiber to produce short-chain fatty acids. Do not spread from one person to another by contact. Moose with winter tick showing hair loss from scratching. coli), Salmonella, Norovirus and Listeria. There is a Cooperative State Federal Brucellosis program in the United States to eradicate the disease from this country. ), fungi, parasitic worms (flatworms and roundworms), and prions. Proper collection, storage and transport of clinical specimens are Protozoan Diseases and Humans. , normal flora) by two or more organisms or species for a necessary, common resource or physical space DOSAGE: the number of pathogenic microorganisms entering the host. Always cook game meat thoroughly to prevent disease. Once in the environment, Types of Pathogens. • Types of Parasites: – Protozoa: Single-celled, microscopic organisms that can perform all necessary functions of metabolism and reproduction. Cryptosporidium parasites are environmentally hardy, withstanding common water treatments such as chlorination, and thus remain a major cause of waterborne outbreaks in industrialized countries as well . Germ theory proposes that microorganisms cause diseases. Many universities have entire departments of plant pathology. Presentation Summary : Hydatid Disease After Humans consume the eggs passed by dogs the worms can form huge cysts in the body Toxoplasmosis How many have of you have heard that Bacteria, viruses and parasites are the sources of many food poisoning cases, usually due to improper food handling. In parasites 1. and then regurgitates the pathogen onto or injects it into a susceptible animal. at raw game meat. For zoonotic diseases that are caused by parasites, the types of symptoms and signs can be different depending on the parasite and the person. A common natural remedy for flushing parasites out of one's system is a blend of 3 herbs: Black walnut (green hull) tincture, wormwood capsules, and fresh ground cloves (to kill the parasites' eggs). A parasite that causes Human parasites. They may be transmitted from animals to humans, from humans to humans, or from humans to animals. - Zoonoses) Zoonotic diseases are those diseases shared by animals and humans. Organism = Parasite or pathogen; Human = Host; Method of spread = Determine factors more common in disease group than healthy group (risk factors). common parasites and pathogens of humans ppt In general, these include roundworms, hookworms, whipworms and tapeworms, and they are very prolific. About Parasites. Chronic infections by parasites account for a high morbidity and mortality in many underdeveloped countries. Look Out! of Human Parasites.

Bacteria, viruses and parasites are the sources of many food poisoning cases, usually due to improper food handling. Skin entry, gut manifestations. Some bacteria, in small amounts, are not harmful to most healthy adults because the human body is equipped to fight them off. Some fungi infect the superficial layer of skin (such as the ringworm fun- gus), and others invade various body systems (such as the aspergillus fungus). All pathogens go through a lifecycle, which takes the organism from reproducing adult to reproducing adult. Macro-parasites can be either classed as endoparasites; parasites that live inside the host, or ectoparasites; parasites that live on the host. Bacteria that cause diseases are called "pathogenic" bacteria. immunology self-defense pathogens: bacteria virus parasites. to kill bacterial pathogens is also suficient to kill parasites Infection from food-borne pathogens may be caused by bacteria, parasites or viruses. Some of the most commonly known include malaria, which is caused by a parasite from the Plasmodium genus, and amoebic dysentery, which is an intestinal inflammation caused by the amoeba Entamoeba histolytica. enteric pathogens appear to be less common than intestinal parasites of animals and is one of the most common causes of human food Some Common Wildlife Parasites and Diseases. Some examples of parasites include roundworms, tapeworms, pinworms, whipworms, hookworms, and more. proposed by Louis Pasteur led to rapid advances in understanding disease Disease-causing agents are called pathogens. Persons working with wildlife should be alert to the potential for disease transmission from animals. These diseases are widespread in Africa, southern Asia, and Central and South America, especially among children. , R. eyes, brain, heart, liver. Common symptoms in humans are undulating fever, weakness, headache, joint pain, and night sweats. org Parasites are of two types such as ectoparasites and endoparasites. , Eustrongylides spp. Predominant intestinal parasites. Waterborne Pathogens: Parasites. The diseases caused by these intestinal protozoan parasites are known as giardiasis, amoebiasis, cyclosporiasis, and cryptosporidiosis respectively, and they are associated with diarrhoea ( 8 ). 1 Ecologists Study Relationships Fig. Approximately 150 zoonotic diseases are known to exist.

The fungus is common in the Great Lakes area of the Upper Midwest and the southeastern and south central regions of Many types of parasites can affect humans. None have adopted multicellular somatic organisation characteristic of metazoan organisms. • Bacteria reproduce rapidly and many give off toxins which damage body tissue. Many types of parasites can affect humans. g. Members of the Hippoboscidae have been given several common names, such as louse. While these pathogens cause a variety of illness ranging from minor to life-threatening, it is important to note that not all microbes are pathogenic. Procedure: 1. Pinworms are a common human parasite, causing enterobiasis. Risk Factors. Skin entry, disease elsewhere. Raccoons in the United States are known to carry infectious diseases that can be transmitted to humans and animals that have contact with raccoons or their waste. Pathogens can also be spread via contaminated food and water. See more about illness-causing bacteria, Hepatitis A virus and parasites ? For more information contact: Julie Albrecht , Ph. The pathogens causing the diseases covered in this manual include viruses, bacteria, rickettsiae, fungi, proto- zoa, and helminths (worms). , Worms) There are quite a few zoonotic diseases, but this segment’s focus will be on parasites that are shed in the stool of your pets. Pathogens are microscopic organisms that cause or have the potential to cause disease. The most common are roundworms, hookworms and tapeworms. Because parasites come in so many different shapes and sizes, Giardia. Germ theory states that microscopic particles cause certain diseases. Most common bacterial cause of diarrhea in the United States, and the most common cause of foodborne deaths. KEY CONCEPT Germs cause many diseases in humans. In this example the leaves are riddled with dead spots brought about by necrotrophic plant parasites.

Intracellular parasites—such as bacteria or viruses —often rely on a third organism, known as the carrier, or vector, to transmit them to the host. touching an infected surface breathing in infected air Ex: SARS Tuberculosis Different pathogens cause common infectious diseases. Some parasites are obligate parasites (require a living host to survive), while others are facultative or nonobligate parasites (do not require a living host in order to survive). Classification of Metazoa Sub kingdom Phylum Class Genus – examples Metazoa Nematodes. com, find free presentations about COMMON PARASITIC DISEASES PPT. raw vegetables infected with eggs. – common Cup fungi, morels, truffles Important plant parasites & saprobes Yeast - Saccharomyces Decomposers, pathogens, and found in most lichens A cluster of asci with spores inside Sac fungi diversity Basidiomycota – “club fungi” Sexual Reproduction – basidia Asexual reprod – not so common Long-lived dikaryotic mycelia Introduction in medical parasitology and parasitic diseases. Chronic infection with viruses and parasites are common in humans, but are absent in laboratory mice, and thus represent potential contributors to inter-species differences in immunity. 6°F - mesophilic bacteria). Zoonotic diseases can be caused by viruses, bacteria, parasites, and fungi. Trypanosoma Protozoa Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness, which is common in Africa. Top 14 Foodborne Pathogens. The symptoms and severity of food poisoning vary, depending on which bacteria or virus has contaminated the food. These organisms include fungi, bacteria, and viruses. Toxoplasmosis: The infection appears to be cosmopolitan. It answers some of the more common questions asked by Aboriginal, domestic, sport and commercial harvesters, and by fisheries researchers. Another definition of parasite is much more narrow; it includes infectious organisms that are not viruses and bacteria. Antibiotics, like penicillin, are substances that are toxic to the bacteria, 1 PATHOGENS AND PARASITES Humans + bacteria = "super-organisms" Humans Functional cells Microsoft PowerPoint - Dye 2b Pandemics. G. Urogenital protozoa e. Diseases caused by viruses include influenza, the common cold, measles, yellow fever, and hepatitis. - Shigella; Like Salmonella, members of this genus are mesophilic, facultatively anaerobic rods and all are considered pathogenic. Discover facts about parasitic diseases, find cool pictures and videos of worms and microscopic parasites. These range from small dark spots to larger dead areas, often ringed by discoloured dying zones. Both young and mature raccoons can shed viruses, bacteria and parasites that when exposed to humans and animals can result in infections and disease. Parasitic Pathogens Affecting the CNS. They include malaria and schistosomiasis, the world's most common serious infectious diseases. Giardiasis is the second-most common parasitic infection in the United States. However, many of them are extremely rare or have human only as accidental host, leaving us with approximately 90 common parasite species pathogenic for human. DE WAAL ** Summary: Diagnosis of parasitic diseases requires highly sensitive and specific tests. About 85% of all plant diseases are caused by fungi. Different categories of pathogens can infect humans
