One of the parasites responsible for action controlling a certain type of snails is the flatworm Leucochloridium Paradoxum. It enters the snail, as the snail eats a bird dropping. The worm develops two sack-like objects, called sporocysts, which fill the snail’s tentacles and pulsate in bright colors. There are two theories concerning this example. The first one is that the parasite controls the nervous system of the snail, and it makes it go to the top of plants (NatGeoWild “World’s Deadliest – Zombie Snails”).
There are three types of parasites that generally infect people. One species of parasites are the anisakid roundworm, they affect people mainly through sea food. Parasites are not a concern in well cooked fish. The three types of parasites that may affect humans are tapeworms, roundworms (nematodes), and protozoa. Some parasites remain in the intestines, others travel through the intestines to obtrude upon other organs.
The white slough can be easily wiped away to reveal erythematous tissue. Sometimes, there is small amounts of bleeding mucosa underneath. Oral candidiasis is most common in newborn infants, older adults who wear dentures, people with diabetes mellitus, and immunocompromised. Oral candidiasis is not only the most common fungal infection in the mouth but it is the most common human fungal infection. According to Akpan and Morgan, Candida Albicans, a type of fungal species from the Candida genus, has been found in the oral cavity and are: 45% in neonates, 50%–65% of people who wear removable dentures, and 95% of patients with HIV.
Moths, cockroaches, fungi, algae, and beetles can all live on a single sloth. Sloths are folivores and have had their digestive system adapt to their eating habits. Leaves are their main food sources and aren’t rich in nutrients; therefore, sloths have large and specialized slow stomachs that have multiple compartments. These compartments contain symbiotic acid which can break down the tough leaves. Sloths have some pretty impressively long tongues.
Tobacco Hornworms consume large amounts of leave tissue. Multiple larvae can completely destroy a tobacco plant, leaving only the stems behind. Early generations of larvae are the most harmful to the tobacco crops. Physiology: The Tobacco Hornworm is typically about four inches long. It is green, with seven white stripes.
These bumps can appear anywhere on the body, though it is unusual to find it on the soles of the feet or the hands. The virus is located in the top layer of the skin, the epidermis, and doesn’t circulate throughout the body. Many people mistake the molluscum contagiosum virus for the common chicken pox virus, but the difference can be found in the characteristics of the lesions: chicken pox spots are water-filled blisters while molluscum are more dome-shaped and pearly. The virus is most common in young children (1-10 years old) and adults. People with weakened immune systems have an especially hard time with the molluscum virus, often suffering a more severe case of the virus while having a more difficult time treating it.
The glow worm or the arachnocampa luminosa is an insect that has a bright green light up tail. The glow worm can live pretty much anywhere on earth that’s not artic. The glow worm is an carnivore so, it eats snails, slugs, or other insects. It has a hard shell to protect it from predators. One of the cons of this insect is it is threatened.
Internally fertilized eggs are deposited in gelatinous mass. The large, yolky egg of terrestrial snails are deposited in moist environments, such as leaf litter, and a calcareous shell may encapsulate them. In marine gastropods, spiral cleavage results in free swimming trochophore larva that develops into another free swimming larva with foot, eyes, tentacles, and shell called a veliger larva. Sometimes, the trocophore is suppressed, and the veliger is primary larva. Torsion occurs during the veliger stage, followed by settling and metamorphosis to the
Critters and livestock like mosquitoes, black rats and chickens that migrated along with the Europeans also carried the bacteria. The contagions held by these creatures consisted of: measles, chicken pox, malaria and yellow fever. Some American diseases that were transferred back to the old world include Chagas disease and supposedly, Syphilis. Although they did have some impact on European populous the effects were seemingly insignificant compared to the impact of the European diseases on the Native
Clinical symptoms: a) Rocky Mountain Spotted Fever: It is considered to be among the most severe of human infectious diseases, with a mortality rate of 20 to 25% unless it is treated with a suitable antibiotic. Naturally, the rickettsia is maintained by the transmission of infected female ticks to infected ova which afterwards hatch into infected larval offspring. When the ticks feed on small mammals with rickettsia in their blood, a low rate of acquisition of rickettsia occurs by uninfected ticks. This effect leads to the destruction of lines of infected
