INTRODUCTION Trypanosomiasis is caused by a parasitic protozoan of the family Trypanosomatidae and genus Trypanosoma. Trypanosomes can infect mammals including humans and can exhibit very high parasitaemia as blood parasites; it is also considered a tissue parasite, due to its ability to invade the nervous system. It is the agent that causes sleeping sickness in humans. This disease in vertebrates is colloquially known as Surra (Derived from Marathi) or Mal de caderas in Brazil but this term was also at times used for rabies. The spread observed in Bolivia around 1840.
Most insects can be killed without seeing them. Pesticide is sprayed, and it sticks to the ends of their legs, and this is then ingested when they eat food. Spiders don 't use the ends of their legs to feed. Insects can also take pesticides back to their nests where others are then killed by the chemicals. Spiders live most of their lives alone, so when you kill one, that is all you 've killed.
The rabies virus does a virus-induced aggressive biting behavior that increases the chances of taking over the host. (The Rabies Virus) The rabies virus can be spread from animals to humans in different ways and can cause many painful symptoms relating to the nervous system. Rabies also has a very complex structure and has multiple functions that can leave people in awe. The nervous system is no match for rabies and most people infected with rabies die unless treated with medication within around 24 hours. Rabies is a viral disease that attacks the nervous system.

They are also snakes, and snakes usually send negative feelings to people because they are venomous and can kill you. The reader can infer that Mildred D. Taylor is trying to tell the reader that the road is not only long and curved like a snake but, it separates the two lands of Mr. Granger and the Logans. If they are cross the road to Mr. Granger’s
Jellyfish, aren 't they amazing creatures, but they can also cause problems too! For example, the grow more out of control each year. There’s also a known fact that the mnemiopsis jellyﬁsh lay 40,000 eggs daily. These “Mnemiopsis jellyﬁsh are responsible for losing millions of dollars for the local ﬁshery industries that sell anchovies”. The overpopulating jelly ﬁsh eat the ﬁsh eggs leaving no ﬁsh for the ﬁsherman.
Some good examples for deadly animals are the great barracuda, box jellyfish, saltwater crocodiles, sharks, and sea snakes. Most people probably know what these things are, but do people know how much power they really have? There are many other animals that can be as dangerous as or even more dangerous than these animals. The animals that were listed previously are extremely dangerous with the saltwater crocodiles bite pound square inch being 3,700 while the toxins of the box jellyfish attack the heart, nervous system, and skin cells, not only that but they have been known to kill a human being from heart failure before the human could even reach
This widespread bubonic plague that is known as the Black Death destroyed countless lives. The plague began in 1348 and the last outbreak took place in 1654 (Pringle 3). This specific plague was an insect-borne disease that wild rodents carried, such as black rats. They carried a pathogen called bacterium Yersinia pestis (Pringle 3). The spreading of this plague was very rapid (Saul 1).
The Red Death Want to hear something scary that a lot of people have to go through alone every year with no help? This is one of the many things that the disease can do to your body. Thomas Geisbert, an immunologist at the University of Texas Medical Branch at Galveston states, "At the end stage of the disease, you have small leaks in blood vessels, you end up with essentially no blood pressure. Your body temperature drops and you go into shock.”(1) Ebola is the worst disease in human history. First, Ebola is one of the most deadly diseases ever.
Malaria is one of the most common infectious diseases prevalent worldwide and can be transmitted by bite of female Anopheles mosquitoes. Nigeria is the country with the largest malaria problem, it is known to kill 300,000 people each year - and 97% of the people living in Nigeria are at risk of catching the disease. (photos.state.gov) Nigeria being an under developed country, with inadequate health care system, diseases like Malaria would affect the economy of the country greatly. As Nigeria is a tropical country, with high humidity and off and on rainfall, makes the environment a conducive for the mosquitoes. The temperature also favors the development of the malarial parasite inside the mosquito causing the parasites to complete their growth cycles.
