Virulence

1. ABSTRACT: A total of 552 serum samples of sheep, goats and cattle from different localities at Assiut governorate, Egypt were screened for qualitative analysis of the BTV antibodies using a commercial competitive ELISA (cELISA) kit. The results showed an overall percentage of BTV positive sheep, goats and cattle serum samples were 41.86%, 24% and 85.42% respectively. A highest percentage of seropositivity was found in Arab El- Awamer farm(100%), followed by Abnoub( 63. 64%), Sedfa(11.…

commonly present in dry surfaces as well as hospitals environment therefore it is known to Couse nonsocial infections for the hospitalized patients [6]. In addition, the virulence factors that produce by this bacteria are the main reasons to Couse drug resistant in this bacteria. Producing biofilm for example is one of the virulence factors which enhanced antibiotic resistance by specific mechanism [6]. This structure is attached to the bacterial surface making the communication between A.…

Staphylococci are…

Hydatid Disease Classification of the causative agent: N. fowleria is an Thermophilic (warm loving) Ameba. Rarely infecting humans. E. granulosus is a parasitic worm called a tapeworm also called dog tapeworm hydatid worm or hyper tape-worm Virulence factors of the causative agent: It has three stages of its lifecycle 1. Cyst Stage which it uses as a form to protect it from the environment or when there is a lack of food. 2.Trophozoiti Stage which is the only stage that it can infect humans…

populations where some of the cells are less permeable to the drug however the more relevant form of resistance occurs when bacteria develop the ability to make chloramphenicol acetyl-transferase. This enzyme is encoded for on a plasmid and acts as a virulence factor…

A common method for creating these medicines is the Vector Method, which includes modifying viruses. Scientist modify viruses by removing virulence, and replace it with genes from another organism. The new virus is then inserted into something in order to create the medicine. Scientist can now produce medicines for cancer, diabetes and many other harmful diseases. GMOs can help to make viruses…

The Blue Death is a mortifying illness that in most cases leads to death within a few days. Cholera is a severe dehydrating disease caused by vibrio cholerae, that affects victims worldwide. It is nicknamed The Blue Death, due to the extreme loss of fluids the body turns bluish-gray color. It is an acute diarrheal disease that causes severe vomiting and diarrhea. The first pandemic occurred in South Asia, in 1817 and continued to spread throughout India, China, the Middle East and Japan. It…

intracellular pathogen which means that infects the macrophages of the bodies immune system.And the reason this bacteria is very effective is because of the waxy coat of Mycolic Acid that onvolves the bacteria.Thia makes staining very difficult and as a key virulence factor for the bacteria. Transmission and Symptoms of Tuberculosis: Transmission is through infected droplets in the air.When someone that is sick with Tuberculosis coughs,sneezes, bits talks infected droplets can get…

Anthrax is a disease caused by the microorganism Bacillus anthracis. This primary pathogen is a zoonotic, aerobic, spore-producing bacillus which is gram positive when tested under a microscope1-4. It is particularly dangerous because of its hardy spores which can survive despite exposure to higher temperatures, light, and multiple disinfectants3. Once the bacteria are picked up by grazing herbivores, the spores begin to germinate and become virulent. As the bacteria continue to develop in the…

The 1918 “Spanish flu” Pandemic was caused by an avian-like influenza virus that gained the ability for efficient and sustained human-to-human transmission and then spread globally, killing 20-50 millions. Fortunately, viruses with pandemic potential are rare occurrences and ongoing surveillance of human and avian viruses is being done globally in preparedness for an influenza pandemic. Vaccines and anti-viral drugs may be available, if needed and time permits. Both kinds of therapies have…
