Biology Casual Agent: The nematode (roundworm) Enterobius vermicularis (previously Oxyuris vermicularis) also called human pinworm. (Adult females: 8 to 13 mm, adult male: 2 to 5 mm. ) Humans are considered to be the only hosts of E. vermicularis. A second species, Enterobius gregorii, has been described and reported from Europe, Africa, and Asia.

Pinworm infection Pinworm infection, also known as enterobiasis, is a human parasitic disease caused by the pinworm. The most common symptom is itching in the anal area. This can make sleeping difficult. The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks.

Biological life cycle In biology, a biological life cycle is a series of changes in form that an organism undergoes, returning to the starting state. The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal. Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different generations of the species succeed each other during the life cycle. For plants and many algae, there are two multicellula

Life Cycle Life Cycle. Mealworms that birds, reptiles, and other animals love aren’t really worms. They are the larvae of darkling beetles. There are over 20,000 different types of darkling beetles and mealworms come from the species Tenebrio molitor. A darkling beetle experiences complete metamorphosis which means that it has four distinct stages of life. The four stages are egg, larva, pupa, and adult.

Pinworms The Facts. The pinworm, or Enterobius vermicularis, is a small parasitic worm that can live inside the human lower intestine. Only 3 mm to 10 mm long, it causes an intense itching in the area of an infected person's anus, especially at night. Pinworms usually infect people as a result of overcrowding in schools and family groupings or due to unsanitary living conditions and poor food preparation.

- Enterobacter aerogenes is a Gram negative rod-shaped bacterium in the same family as Esherichia coli.It can grow on many of the same selective media as Esherichia coli, including: MacConkey Agar, EMB agar and Lauryl-Tryptose broth.) E. coli is positive in the methyl red test while E. aerogenes is usually, but not always, negative (this is not the best test to rely on). 4) E.coli is positive for the indole test while E. aerogenes is negative, this is a very reliable test. 5) E. aerogenes can grow on Simmon's citrate agar while E. coli does not.

Bed Bug Life Cycle & Biology Life Cycle & Biology of a Bed Bug: Eggs, Nymphs, Adults. The life cycle of an insect describes the development of an insect from the egg stage to adult. The process is referred to as metamorphosis. Metamorphosis is the process that the insects undergo to change from egg to adult.o the bed bug life cycle goes from egg to nymph, progressing through five nymphal stages, to adult, which then lays eggs and the process starts again.

Cholera bacteria infect more effectively with a simple twist of shape Princeton University researchers have identified the protein that allows Vibrio cholerae -- the bacteria behind the life-threatening disease cholera -- to morph into a corkscrew shape that allows them to more effectively penetrate their victims' intestines.

Trichinella spiralis Trichinella spiralis is a common parasite of carnivorous and omnivorous mammals, including humans. There are three different ecological types of life cycles, the urban cycle, the sylvatic cycle, and the marine cycle. In the urban cycle, rats and pigs serve as hosts and reservoirs of the parasite.

Helminths Ascaris is the name of a particular helminth, and Ascariasis is the name of the infectious disease caused by this helminth. Helminths are worm-like organisms living in and feeding on living hosts, receiving nourishment and protection while disrupting their hosts' nutrient absorption, causing weakness and disease.he nematodes are the most diverse of all the helminths with the highest number of species. Characteristics that are common for all helminths include: Life time: 1  The life time of adult worms varies tremendously from one species to another but is generally in the range of 1 to 8 years (see following table).

Spiralian gastrulation: germ layer formation, morphogenesis, and fate of the blastopore in the slipper snail Crepidula fornicata Theories about the evolution of gastrulation often concern the fate of the blastopore (site of endomesoderm internalization), which varies widely in a major branch of bilaterians, the Spiralia. In this group, the blastopore has been said to become the mouth, the anus, both, or neither.

5 Different Types of Bacteria Members of the vibrio group represent one of the three types of bacteria that have a spiral shape. Vibrio bacteria are comma-shaped, appearing like curved rods. They typically live in aquatic environments and move in a darting motion using a single flagellum, a whip-like structure.

Treating Pinworms The pinworm, or Enterobius vermicularis, is one of the most common parasitic infections of humans. Somewhere between 10% and 40% of children have pinworms at any given time (Pediatric Consult, Williams and Wilkins 1997). The infections are usually limited to children below the age of twelve.

Vibrio vulnificus: A summertime bacteria While the bacteria are real, public health officials say the flesh-eating part is not. Vibrio vulnificus is a naturally occurring bacterium that lives in warm saltwater and infects humans through the consumption of undercooked shellfish and skin wounds.ibrio vulnificus multiplies in warmer water temperatures and tends to reach peak levels in midsummer, according to Mody, so the higher bacteria count coincides with the height of beach season. This adds to the public's fear of the bacteria. After all, no one wants to get a limb amputated while on vacation.
