The nervous system of a Lumbriculus worm is very exposed and visible, so different plants and herbs were tested to see how it would affect the heart rate of the Lumbriculus worm. This is important because before potentially harmful products are tested on humans, they should be tested on the worms. First, a pre-test hypothesis (Pau D’Arco is a stimulant) is made about what a certain extract (Pau D 'Arco) will do to the worms heart rate. A worm was chosen and put into a cup of conditioned (unchlorinated) water to sit for ninety seconds. The worm was very squirmy and active during the ninety seconds.
Some parasites remain in the intestines, others travel through the intestines to obtrude upon other organs. Tapeworms and roundworms grow in host’s body and lay their eggs there; the eggs are then passed out of the body through fecal matter and are able to inhabit others. Intestinal parasites are more likely to spread in areas with poor sanitation, such as developing countries on the African, Asian, and South American continents.
Tetanus Muscular System Tetanus, also known as lockjaw, is a serious bacterial infection called Clostridium tetani, that causes serious painful muscle spasms and can lead to death. Clostridium tetani spores are able to for long periods outside of the body. These spores found mainly in animal feces and contaminated soil, but they can survive anywhere. The bacteria enters the body through puncture wounds. Tetanus can enter the body by; animal bites, skin burns, body piercing and tattoos done with unsterile tools, injection of drugs with contaminated needles, abrasion and laceration, and even circumcision.
Common ways of transmission can be from nail and needle punctures and burns. Other least common but possible ways of getting tetanus can be from clean superficial wounds, insect bites, dental infections and IV drug use (2). Tetanus can infect people of all ages but is most common in newborns. Neonatal tetanus is most commonly found in rural areas because sterile delivery procedures may not be available. The tools used to cut the umbilical cord or perform a circumcision may be dirty and contaminated.
Ok, I will give the name it is most commonly associated with, flesh eating bacteria syndrome. This name is, in fact, an inappropriate name for the infection, since the bacteria does not actually “eat” the tissue, it destroys it by releasing toxins. The bacterias that most commonly causes this disease are group A streptococcus (Streptococcus pyogenes), Staphylococcus aureus, and Clostridium perfringens. These bacterias come in through the skin and infect surrounding tissue. People who are immunocompromised, such as cancer and diabetes sufferers, have greater risks of getting flesh eating bacteria.
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
Alveolar echinococcosis (AE) is characterized by parasitic tumors in the liver and may spread to other organs including the lungs and brain. In humans, the larval forms of E. multilocularis do not fully mature into cysts but cause vesicles that invade and destroy surrounding tissues and cause discomfort or pain, weight loss, and malaise. AE can cause liver failure and death because of the spread into nearby tissues and, rarely, the brain. AE is a dangerous disease resulting in a mortality rate between 50% and 75%, especially because most affected people live in remote locations and have poor health care. (Thompson RA.
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.
In vegetated habitats, rainbow trout often have the opportunity to eat terrestrial insects that fall into the water such as ants, beetles, and crickets. The prey of rainbow trout may include small fish up to one-third of their length, crayfish, shrimp, and other crustaceans; but their most important food is freshwater shrimp, containing the carotenoid pigments responsible for the orange-pink color in trout flesh. They may also consume decomposing flesh from carcasses of other
The disease was carried by fleas and transmitted by rodents. The illnesses of the Elizabethan era are similar to the sicknesses in the modern age. Broken bones or wounds would be treated and cared for in unsanitary areas. This is unsafe because the wounds would get infected really easily. Lower and upper class people would die from illnesses due to poor living conditions.
