  • phylum
  • The definition of Protozoa as a phylum or sub-kingdom made up of "unicellular animals" was adopted by the zoologist Otto Bütschli-celebrated at his centenary as the "architect of protozoology"-and the term came into wide use. (wikipedia.org)
  • As a phylum under Animalia, the Protozoa were firmly rooted in the old "two-kingdom" classification of life, according to which all living beings were classified as either animals or plants. (wikipedia.org)
  • unicellular
  • Protists were traditionally subdivided into several groups based on similarities to the "higher" kingdoms such as: Protozoa the unicellular "animal-like" (heterotrophic/parasitic) protozoa which was further sub-divided based on motility such as (flagellated) Flagellata, (ciliated) Ciliophora, (phagocytic) amoeba and spore-forming Sporozoans Protophyta the "plant-like" (autotrophic) protophyta (mostly unicellular algae) Molds the "fungus-like" (saprophytic) slime molds and water molds. (wikipedia.org)
  • After the cell theory of Schwann and Schleiden (1838-39), this group was modified in 1848 by Carl von Siebold to include only animal-like unicellular organisms, such as foraminifera and amoebae. (wikipedia.org)
  • The formal taxonomic category Protoctista was first proposed in the early 1860s by John Hogg, who argued that the protists should include what he saw as primitive unicellular forms of both plants and animals. (wikipedia.org)
  • cats
  • Infection rates in cats reflect the rate of infection in local avian and rodent populations because cats are thought to become infected by eating these animals. (usda.gov)
  • Additionally, environmental data were recorded including presence of common water source shared with other animals in the ranch, cohabitation with other animals (cats, dogs, cattle), and climatic conditions. (beds.ac.uk)

  • Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). (wikipedia.org)
  • bacteria
  • In fact, less than 1 percent of bacteria cause diseases in humans. (scribd.com)
  • For example, harmless anaerobic bacteria, such as Lactobacilli acidophilus, live in our intestines, where they help to digest food, destroy disease-causing microbes, fight cancer cells, and give the body needed vitamins. (scribd.com)
  • For example, the phrase "protist pathogen " may be used to denote any disease-causing microbe which is not bacteria , virus , viroid or metazoa . (wikipedia.org)
  • Apicomplexa
  • 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. (wikipedia.org)
  • chronic
  • Near the end of the 20th century, researchers began to learn that microbes also contribute to many chronic diseases and conditions. (scribd.com)
  • Mounting scientific evidence strongly links microbes to some forms of cancer, coronary artery disease, diabetes, multiple sclerosis, and chronic lung diseases. (scribd.com)
  • kingdoms
  • He defined the Protoctista as a "fourth kingdom of nature", in addition to the then-traditional kingdoms of plants, animals and minerals. (wikipedia.org)
  • In Hoggs's conception, the animal and plant kingdoms were likened to two great "pyramids" blending at their bases in the Kingdom Primigenum. (wikipedia.org)

  • babesiosis
  • Human babesiosis is an uncommon but emerging disease in the Northeastern and Midwestern United States and parts of Europe, and sporadic throughout the rest of the world. (wikipedia.org)
  • Ticks transmit the human strain of babesiosis, so it often presents with other tick-borne illnesses such as Lyme disease. (wikipedia.org)
  • A reported increase in human babesiosis diagnoses in the 2000s is thought to be caused by more widespread testing and higher numbers of people with immunodeficiencies coming in contact with ticks, the disease vector. (wikipedia.org)

  • Infection is through contaminated material such as earth, water, uncooked or cross-contaminated food that has been in contact with the feces of an infected individual or animal. (wikipedia.org)
  • fungi
  • This kingdom does not form a clade, but an evolutionary grade or paraphyletic group, from which the fungi and animals are specifically excluded. (wikipedia.org)
  • As long as this scheme remained dominant, the protozoa were understood to be animals and studied in departments of Zoology, while photosynthetic microorganisms and microscopic fungi-the so-called Protophyta-were assigned to the Plants, and studied in departments of Botany. (wikipedia.org)
  • Researchers
  • The researchers have used these cancer stem cells to test a new therapeutic approach that one day might be used to treat some of the more aggressive types of this disease. (bioquicknews.com)
  • When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced pleasure-seeking - they avoided other animals and lost their sweet tooth. (bioquicknews.com)
  • The use of Protozoa as a formal taxon has been discouraged by some recent researchers, mainly because the term, which is formed from the Greek protos "first" + zoia, plural of zoion, "animal", implies kinship with animals (metazoa) and promotes an arbitrary separation of "animal-like" from "plant-like" organisms.
