Lungworms is an infection of the lower respiratory tract, usually resulting in bronchitis or pneumonia, can be caused by any of several parasitic nematodes. The way that the worm affects the lungs is that it will gradually damage the airways or lung tissue by inciting an inflammatory reaction inside the tissue. Ultimately, the parasites survive and reproduce in the respiratory tissues. The way that the livestock animals contact this parasitic host is when young or old livestock that have weaker immune systems contract the larva into their lungs. Which allows the parasite to multiply and spread because the animal’s body isn’t strong enough to fight it off. The livestock that are more susceptible to get this is sheeps, goats, horses, and cattle but they are different kinds of lungworms such as Dictyocaulus viviparus, D filaria, and D arnfieldi. So when that livestock poops it puts that larvae and worms on the ground where the livestock graze. …show more content…
This orange fungus, regularly seen on cow dung pats in pastures, explodes, spreading the lungworm larvae all over the pasture. To know if your livestock has contracted this it will have shortness of breath, fever, Coughing (particularly after excitement), in severe infestations open mouth breathing, Bacterial or viral pneumonia, severe cases of lungworm infestation causes stunting of growth, poor thrive and chronic lung damage, often leading to relapses as the animal gets older. There are many symptoms to let you know that if your animals have lungworms. These parasites are more common in Europe because the climate is colder and it is rainy as well so they thrive in their low pressure environment but as the year goes on and the temperature rises to approach the summer season the parasite dissipates to almost zero. Rather than in North America because of the climate is more warmer but the worm will appear somewhat in the northern states because the climate is
Bess beetles range in size all the way from 21 millimeters to 80 millimeters. The beetles are named after the French word baiser, which means “to kiss”, due to the fact that they often make a smooching sound with their legs. They have a small horn that protrudes from their head, and use their antennae to drive them forward when experiencing new smells. Though the beetles may look quite menacing, they are surprisingly docile. They enjoy feasting on rotten wood, moss, and adult beetle fecal matter after it has been partially digested by bacteria. A scientific experiment was conducted to test these beetle’s pulling power in relation to their mass. The hypothesis stated,
ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
In cattle feedlots, the conditions are very bad. Most of the time, the feeder calves are standing in mud that is two feet deep. In these moist conditions, bacteria thrive. The cattle can suffer from foot problems, like foot rot. foot rot is a disease of the hoof which the skin between the toes of the hooves rots away and decomposes. If left untreated, the foot will swell and will rot off. This is extremely painful for the animal(Hasheider 34). In these feed yards, the feed is dumped into concrete feed bunks three times a day, and that is all the cattle get to eat. They are not offered grass or any type of forage, the forage, also known as hay...
This final microbe is far less dangerous and easier to comprehend than the formerly mentioned ones. Histoplasma Capsulatum, often called histoplasmosis, is caused by a fungus called Histoplasma (1). This fungus thrives within earthy environments with lots of soil filled with bird and bat droppings (1). It is found mainly in the United States, specifically within the central and eastern states, such as around the Ohio and Mississippi river valleys (1). The fungus can also be found within central and South America, Africa, Asia, Australia, and small parts of Europe (1). While most people do not get sick, those who do become infected when breathing in the microscopic fungal spores in the air (1). Symptoms
The meningeal worm is also known as the brain worm, or the deer worm. It frequently infects llamas and alpacas, but can infect other species as well like moose, elk, goats, and sheep. The meningeal worm is an internal parasite that is a part of the protostrongylidae family with the definitive host being the common white tailed deer. Even though they are the host, adult meningeal worms rarely cause clinical signs of disease in the deer. The white tail deer’s tolerance to infection from these worms is actually beneficial to the parasite because the white tail deer are the only species that will allow the worm to complete their life cycle. So alpacas and llamas are unsuitable hosts and that is why the meningeal worm is such a threat to them. It can cause varying degrees of damage to their central nervous system. “The cerebrospinal fluid tap is especially useful for diagnosing meningeal worm and ruling out other diseases.” (Whitehead, Bedenice 2009.) Ruling out other diseases helps to narrow down what could be ...
Oftentimes, people can recall at least one song they know that is undoubtedly catchy because of its repetitive nature. That song can become a nuisance, when it will not leave your mind. When a melody gets stuck in your head, sometimes it could take a whole day to forget the tune. A certain tune can be stuck in your brain for many years! In Oliver Sacks’ passage, “Brainworms, Sticky Music, and Catchy Tunes”, he talks about “earworms”, or a pathological repetition. Sacks uses patterns of development to inform the modern reader about the dark side of music.
The biting midge (Culicoides imicola), which is responsible for this disease’s transmission, is usually contained within Mediterranean Europe; where the conditions have been exactly what the midge demands to survive (Society for General Microbiology NP). However, with an increase in average temperature of six degrees, the midge has been allowed to travel northward threatening the cattle throughout the area and even as far as England (Society for General Microbiology NP). The spread of the midge’s territory has led to an increased number of their population, along with the amount of infected cattle.
The most common way this disease is transmitted from one animal to the next is through mosquitoes. A mosquito carrying infective heartworm larvae bites a dog and transmits the infection to them. The larvae grow, develop, and migrate in the body over a period of 6 to 7 months, in which time they become sexually mature male and female worms. this is the prepatent period. The worms then reside in the heart, lungs, and associated blood vessels. The worms begin to mate and release microfilaria into the blood stream. When a mosquito bites an infected dog it takes in some of the microfilaria in the blood. After 10 to 30 days there is larvae in the mosquito’s salivary gland which can then be passed on to the next dog the mosquito bites.
182 people became infected, and 29 died (most of which were older men or cigarette smokers). Although this organism was named in the 70’s, retrospective studies have shown cases since 1943. GRAPH Diseases: L. pneumophila has a very wide range of effects. Healthy individuals usually go through an asymptomatic seroconversion, while less healthy people may undergo Pontiac Fever or Legionnaires’ Disease (LD). In 1968, employees at the county health department in Pontiac, Michigan came down with a fever, but the responsible pathogen was not identified at the time.

This parasite is spread through the bite of sandflies. There are three different types of infections and they each show varying degrees of severity. The cutaneous form produces mild skin ulcers, mucocutaneous produces ulcers in the mouth and nose, and the visceral form of the disease starts with skin ulcers and then fever, low red blood cell count, and an enlarged spleen and liver. The parasite is detected by a microscope and visceral can also be found by doing blood tests. 12 million people are in infected in 98 different countries and 2 million new cases are found every year. The disease also kills around 20 to 50 thousand people a year.
is spread to humans by fleas from infected rodents. In the 1300s, fourth of the population
However, health concerned organizations want to ban the use of these products due to the increasing fears that they can cause harm to the consumers. For over 50 years, antibiotics have been added to the food of animals such as poultry, cattle and pigs. The main purpose for doing so is to lower the risk of disease in animals. Farm animals are housed together in overcrowded areas, which are very dirty. The hygiene level can get to such a poor state that they are often in contact with their own excreta as well as excreta of the other animals they are housed with and because of tight single air space they share, the likelihood of catching diseases from one another is further increased and very often a whole heard can be infected at one time.
The type of cancer I decided to research was lung cancer because it was something that was interesting to me. It interests me because I know a lot of people that have smoked and have gotten this type of cancer. A few of the leading causes to lung cancer is smoking and environmental toxins.The types of smoking products that are used that can cause this type of cancer are ones you buy from the store or illegal drugs. There are different types of environmental toxins. If these types are ingested the result could be cancerous. These toxins include and not limited to; asbestos which is a type of insulation used in houses, carcinogens; toxins in cigarette smoke, and benzene; a toxin that is a natural part of crude oil and gasoline, etc.
This year thousands will be affected by some form of lung cancer. Many do not know what lung cancer is and what its effects are. Also, unknown to most are the causes of this cancer. Another factor of lung cancer people do not understand is how many are victims to this disease. Lung cancer is a disease of which many people have heard of but do not understand what it is and what it does, what causes it, and how many it is affecting.
