Cryptosporidium: What You Should Know
 
03:09
Cryptosporidium lives in the intestine of infected humans and animals. It is a microscopic parasite that may be found in soil, food, water, or surfaces that have been contaminated with the feces from an infected host. Cryptosporidiosis is the name of the diarrheal disease caused by Cryptosporidium. Both the disease and the parasite are commonly referred to as "Crypto." An infected person or animal sheds the parasites in their stool. In fact, millions of the parasites can be released in a bowel movement from an infected human or animal. The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it very resistant to chlorine-based disinfectants. Crypto can be spread: • By putting something in your mouth or accidentally swallowing something that has come into contact with waste infected with Crypto. • By swallowing recreational water contaminated with Crypto. • By swallowing contaminated water or beverages. • By eating uncooked food contaminated with Crypto. • By touching your mouth with contaminated hands. People in buildings that have suffered from a sanitary sewer overflow or due to a flooding event should be aware of this parasite. Child care workers who change diapers and healthcare workers are also at risk. The most common symptom of cryptosporidiosis is watery diarrhea. Other symptoms include: • Stomach cramps or pain • Dehydration • Nausea • Vomiting • Fever • Weight loss Some people with Crypto will have no symptoms at all. While the small intestine is the site most commonly affected, Crypto infections could possibly affect other areas of the digestive tract or the respiratory tract. These are just a few things to know about Cryptosporidium, to learn more about this or other environmental, health and safety, occupational or indoor environmental issues, please visit the websites shown on the video.

David Roos (U Penn) Part 1: Biology of Apicomplexan Parasites
 
32:06
https://www.ibiology.org/microbiology/apicomplexa/ There are more than 5000 species of single-celled eukaryotes in the biological phylum known as the Apicomplexa, including the parasites responsible for malaria, neurological birth defects, and opportunistic infections associated with HIV/AIDS. These ancient protozoa provide a unique window into the evolution of subcellular organelles that have long fascinated cell biologists. Familiar features help to elucidate the origins, functions and design parameters for the secretory pathway, endosymbiotic organelles, the cytoskeleton, and cell cycle control. Conversely, parasite-specific organelles highlight the evolutionary diversity of eukaryotes, and suggest novel targets for treating disease. See more at http://www.ibioseminars.org

Colostrum
 
08:08
Colostrum (also known colloquially as beestings, bisnings or first milk) is a form of milk produced by the mammary glands of mammals (including humans) in late pregnancy. Most species will generate colostrum just prior to giving birth. Colostrum contains antibodies to protect the newborn against disease, as well as being lower in fat and higher in protein than ordinary milk. This video is targeted to blind users.

Sporozoa | Wikipedia audio article

This is an audio version of the Wikipedia Article: Sporozoa Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ In case you don't find one that you were looking for, put a comment. This video uses Google TTS en-US-Standard-D voice. SUMMARY ======= The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic alveolates. Most of them possess a unique form of organelle that comprises a type of plastid called an apicoplast, and an apical complex structure. The organelle is an adaptation that the apicomplexan applies in penetration of a host cell. The Apicomplexa are unicellular and spore-forming. All species are obligate endoparasites of animals, except Nephromyces, a symbiont in marine animals, originally classified as a chytrid fungus. Motile structures such as flagella or pseudopods are present only in certain gamete stages. The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: Babesiosis (Babesia) Malaria (Plasmodium) Cryptosporidiosis (Cryptosporidium parvum) Cyclosporiasis (Cyclospora cayetanensis) Isosporiasis (Isospora belli) Toxoplasmosis (Toxoplasma gondii)The name of the taxon Apicomplexa derives from two Latin words—apex (top) and complexus (infolds)—and refers to a set of organelles in the sporozoite. The Apicomplexa comprise the bulk of what used to be called the Sporozoa, a group of parasitic protozoans, in general without flagella, cilia, or pseudopods. Most of the Apicomplexa are motile, however, by use of a gliding mechanism that uses adhesions and small static myosin motors. The other main lines were the Ascetosporea (now in Rhizaria), the Myxozoa (now known to be highly derived cnidarian animals), and the Microsporidia (now known to be derived from fungi). Sometimes, the name Sporozoa is taken as a synonym for the Apicomplexa, or occasionally as a subset.

Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.Water pollution can be grouped into surface water pollution. Marine pollution and nutrient pollution are subsets of water pollution. Sources of water pollution are either point sources and non-point sources. Point sources have one identifiable cause of the pollution, such as a storm drain, wastewater treatment plant or stream. Non-point sources are more diffuse, such as agricultural runoff. Pollution is the result of the cumulative effect over time. All plants and organisms living in or being exposed to polluted water bodies can be impacted. The effects can damage individual species and impact the natural biological communities they are part of. The causes of water pollution include a wide range of chemicals and pathogens as well as physical parameters. Contaminants may include organic and inorganic substances. Elevated temperatures can also lead to polluted water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition, reduce species biodiversity, and foster invasion by new thermophilic species.Water pollution is measured by analysing water samples. Physical, chemical and biological tests can be done. Control of water pollution requires appropriate infrastructure and management plans. The infrastructure may include wastewater treatment plants. Sewage treatment plants and industrial wastewater treatment plants are usually required to protect water bodies from untreated wastewater. Agricultural wastewater treatment for farms, and erosion control from construction sites can also help prevent water pollution. Nature-based solutions are another approach to prevent water pollution. Effective control of urban runoff includes reducing speed and quantity of flow. In the United States, best management practices for water pollution include approaches to reduce the quantity of water and improve water quality.

Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult.Non-point source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Non-point source air pollution affects air quality from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a non-point source of pollution. Non-point source pollution can be contrasted with point source pollution, where discharges occur to a body of water or into the atmosphere at a single location. NPS may derive from many different sources with no specific solution may change to rectify the problem, making it difficult to regulate. Non point source water pollution is difficult to control because it comes from the everyday activities of many different people, such as lawn fertilization, applying pesticides, road construction or building construction.It is the leading cause of water pollution in the United States today, with polluted runoff from agriculture and hydromodification the primary sources. Other significant sources of runoff include habitat modification and silviculture (forestry).Contaminated stormwater washed off parking lots, roads and highways, and lawns (often containing fertilizers and pesticides) is called urban runoff. This runoff is often classified as a type of NPS pollution. Some people may also consider it a point source because many times it is channeled into municipal storm drain systems and discharged through pipes to nearby surface waters. However, not all urban runoff flows through storm drain systems before entering water bodies. Some may flow directly into water bodies, especially in developing and suburban areas. Also, unlike other types of point sources, such as industrial discharges, sewage treatment plants and other operations, pollution in urban runoff cannot be attributed to one activity or even group of activities. Therefore, because it is not caused by an easily identified and regulated activity, urban runoff pollution sources are also often treated as true non-point sources as municipalities work to abate them.

Plastids were discovered and named by Ernst Haeckel, but A. F. W. Schimper was the first to provide a clear definition. Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color. They have a common evolutionary origin and possess a double-stranded DNA molecule that is circular, like that of prokaryotic cells.
