Hello friends how are you all? Hope you are doing well. Today I will discuss Rickettsia in front of you. Hope you all like it. I will present to you about the discovery of its structure. So let's start my post.
Protocellular micro-organisms living as intracellular parasites of arthropods such as lice, flies, cockroaches. Dear Marfiq gram negative. Incapable of producing spores. Danhab Sangh is known as Electrician. It is generally called a type of parasite. Which cannot be seen without a microscope, due to its very small size, its structure is very complex.
In 1083 AD, an outbreak of an unknown fever occurred in a place called Saleno. A scientist named fraclastorius first described this disease as an epidemic in 1546 AD. He was not able to identify the cause of the disease. Many deaths were reported. The disease was named epidemic typhus and the microorganism responsible for the disease was named Rickettsia, a deadly disease.
American physician Dr. Howard Taylor discovered its germ in 1906. He observed the presence of a type of rod-shaped bacteria in the blood of patients suffering from this disease. He concentrated on discovering the germs of typhus in Mexico in 1910 and noted that the disease spread with the help of lice. He was able to prove that Rocky and the typhus paper germ were similar. HT Rickett Shea himself died of typhoid during his research on typhoid germs which is a tragic event as there are many medical scientists who have died during research whose research is unforgettable and which has led our future generations to the light.
Several other scientists died of fever while researching the transmission of typhus fever. Many years later, after extensive research, a scientist in Brazil accurately identified the true cause of typhus fever, which is because rickets is a microscopic microorganism larger than a virus. But smaller than bacteria. It ranges from 0.3 mm to 1 mm in length and 0.5 mm in diameter. Its shape is rod round or polymorphic. It has a cell wall and cell membrane, i.e. it has a membrane, but its cell does not have a real nucleus, due to which it cannot carry out the functions of its nucleus. That is why it is a protocellular organism. Mesosomes etc. are present.
Chemical composition analysis revealed that its cell wall is mainly composed of mucolisaccharides. In addition, meuramic acid and amino sugars are present in the cell wall, some enzymes have been found in the cells of rickettsia singly or together with two diplomycelus types, i.e. two rod-shaped rickettsia are located together. In such a case, the object shows a brand in the middle and the ends of the rod-shaped cells appear relatively narrow. This organism is an intracellular parasite which needs two to complete its life cycle first host arthropod and any beetle mosquito etc. and second host vertebrate animal human mouse etc. living reproductive cells it is sick it is unable to multiply live pus cytoplasm division method rickettsia increases the number .
So this was some of my writing. Hope you all like it. Thank you all for commenting.
