Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae . T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle .
All adult tardigrades of the same species have the same number of cells (see eutely). Some species have as many as 40,000 cells in each adult, while others have far fewer. [23] [24] The body cavity consists of a haemocoel, but the only place where a true coelom can be found is around the gonad. No respiratory organs were found, with gas ...
E. coli belongs to a group of bacteria informally known as coliforms that are found in the gastrointestinal tract of warm-blooded animals. [ 49] E. coli normally colonizes an infant's gastrointestinal tract within 40 hours of birth, arriving with food or water or from the individuals handling the child.
Cnidaria. Cnidaria ( / nɪˈdɛəriə, naɪ -/ nih-DAIR-ee-ə, NY-) [ 4] is a phylum under kingdom Animalia containing over 11,000 species [ 5] of aquatic animals found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
Listeria monocytogenes. (E. Murray et al. 1926) Pirie 1940. Listeria monocytogenes is the species of pathogenic bacteria that causes the infection listeriosis. It is a facultative anaerobic bacterium, capable of surviving in the presence or absence of oxygen. It can grow and reproduce inside the host's cells and is one of the most virulent ...
Low-temperature electron micrograph of a cluster of E. coli bacteria, magnified 10,000 times. Each individual bacterium is a rounded cylinder. Each individual bacterium is a rounded cylinder. Certain strains of E. coli , such as O157:H7 , O104:H4 , O121 , O26 , O103 , O111 , O145 , and O104:H21 , produce potentially lethal toxins .
Breed, lack of water, exercise, and high ambient temperature predispose dogs to heat stroke. Signs include vomiting, diarrhea, collapse, difficulty breathing, and body temperature approaching 42 °C to 43 °C. Treatment includes cooling the dogs with wet towels and fans, intravenous fluid therapy, and other supportive care. [171]
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
