They lack digestive tract, mouth and senory organs, they have unique body extension called microtiches which help in absorption of host nutrients. They have scolex which is provided with suckers and often with hooks for attachment. More than 10,000 species of tapeworms are known to science. The most common species of tapeworm in humans are fish tapeworm, beef tapeworm, pork tapeworm, dwarf tapeworm, dog tapewom, uniocular hydatid and multiocular hydatid. 1.
Fleas and Ticks Cat Flea - Centocephalides felis Appearance Cat fleas are reddish-brown in color, and are about 1/6 inch in length or a little smaller than a sunflower seed. In the larval stage they are only 1/16 inch long worm-like and white. Behavior Fleas are ectoparasites and feed on the blood of birds, mammals, and reptiles. They have a relatively short life cycle and can rapidly reproduce. Once they have attached to a host they will begin feeding.
The disease symptoms range from stalk rot and foliar damage to peduncle breakage and grain deterioration (Tesso et al. 2012). Leaf symptoms of anthracnose typically appear as circular or elliptical to elongated lesions, with dark reddish-purple color to tan. The center of the lesion is straw-colored with reddish-brown or reddish-orange margins with numerous black fruiting bodies (acervuli) with setae (hairlike structures protruding from the acervuli) (Pastor-Corrales and Frederiksen 1980; Cunfer 2015; Kucharek 1992; Casella et al. 1998; TeBeest et al.
It has aboreal living style and omnivore and eat every type of food as grain, fruit etc.Rattus rattus (black rat) is omnivores. They are infectious pests and eat bird and some arthropods they destroy many agricultural crops. They can cause Yersinia pestis that result in bubonic plague (Amori et al).it caused serious plague in Europe in medieval era and its movements produced serious
Sputum contains a lot of bacteria, viruses, fungi and other pathogens. Respiratory infectious diseases, like influenza, tuberculosis, bronchitis, pneumonia, measles, pertussis, diphtheria and other pathogens, are spread through the sputum, very dangerous. Spitting there are many hazards, not only can cause health problems, in infectious disease multiple times, phlegm is a highly damaging route of transmission, inadvertently freely spit sputum are likely to have increased 10 people infected with the virus. First of all, spitting could lead to spread bacteria, into the air will harm to people. In our usual life, no spitting everywhere slogan, the reason is spitting is an extremely uncivilized unsanitary, spitting will make sputum bacteria spread easily, especially in public places, crowded place will make the spread of the virus.
Gastroenteritis:. Infection of the stomach or intestine is called gastroenteritis. Even though viruses cause gastrointestinal infection but bacteria also cause such infections by infecting the lining of the intestine or the stomach. stomach is infectad by large number of pathogenic microorganism and this infection is usually extends to the nearest structures which are the esophagus proximally and duodenum distally. Stomach infections is caused by two gerneral situations which are gastritis and gastroenteritis.
Pygmy goats tend to be kept as pets primarily, though also work well as milk producers and working animals. The pygmy goat is quite hardy, an asset in a wide variety of settings, and can adapt to just about every climate. These goats are pretty much just wacky animals, they like jumping on random surfaces and usually have a good amount of energy. They also need companions, which means if you buy one, you need to buy a second one. Altogether, the pygmy goat makes a great pet.
Among the many types of cancers, lung cancer is one of the most common diseases that smoking can cause. Inhaling cigarette smoke that is full of cancer-cause substances like carcinogens, which includes tar, causes lung cancer. Tar is brown, syrupy substance that contains poisons according to ‘Drugs’. Those substances may change the tissue (Human body tissue is made up with groups of cells which have similar structure that are working along for the function in human body) in the lungs quickly and when cigarette smoke passes through the lungs, it leaves tar. Although, the body produces mucus to prevent the effects of tar, it can block the way of the air that goes into the body and out and lung.
4. PAVEMENT ANTS- Although these ants can live inside, they get their name because they make their nests under the cracks in pavement. They are typically found in the eastern half of the United States, California and Washington. These ants will eat almost anything, including insects, grease, seeds, honeydew, honey, bread, meats, nuts and cheese. .
Human to human transmission is extremely rare and reported only with cutaneous anthrax. When the animal dies due to anthrax, the animal carcasses become infectious, and when the animal decomposes, the spores can again mix with the soil and the transmission cycle continues. The bacterium often penetrates the body via wounds in the skin and may also infect humans as aerosol or ingestion. The ability of sporulation and resistance of the spores to harsh environmental conditions like heat and humidity, disinfectants and UV radiation makes anthrax the most important biological warfare agent. It is reported that the spores can survive up to 40 years in water or soil.
The cause and source of the bubonic plague were fleas. Fleas were the carriers for the bubonic plague. On their own, fleas cannot travel vary far, but fleas can be transported on other animals, mainly mammals. During the thirteen hundreds, ships were really making some major advancements, allowing them to sail year round instead of during certain seasons or weather conditions. Some problems on the ship, though, were the rats.
The feces of the beetles that were fed antibiotics was chock full of caffeine. Then, the beetles were given a chance to breed which resulted in failure; most of the eggs and larvae died because of the loss of the microbe. Scientists found HhMAN1
By adding the chart to the website, it made it easy for the reader to compare different types of avocados and how they will grow in different elements. The paragraphs are easy to read and well labeled. The HGTV website had only basic information that makes it seem easy to go run out and grow a tree. It is also a very busy webpage that makes it fairly difficult to
Plutella xylostella (L.), the diamondback moth (DBM), is a serious pest of crucifers and has been reported from all US states. The most affected vegetable crops in the United States are cabbage, broccoli, cauliflower, collard, mustard, radish, and turnip and major damage to the crops is caused by larval feeding. DBM has been known to travel long distances (Chapman et al., 2002). The annual total estimated cost for DBM management is 4 to 5 billion dollars globally and 150 to 200 million dollars in the United States (Zalucki et al., 2012). Despite many advances, DBM has retained its status as the most destructive member of the different insect pest complexes that attack crucifer crops in various parts of the world and has shown the substantial
For instance, due to them eating insects and other organisms they help farmers maintain their crops healthy. Spiders can also help prevent more people from getting infected of Malaria. Not only are spiders beneficial predators but they are also the prey for other organisms. Spiders are another food source for many organisms in the food chain. In many ways spiders are important in the food chain; they affect the chain no matter what role they play.
