Rocky Mountain Spotted Fever Rickettsia rickettsia was named after the first person who discover Rocky Mountain Spotted fever‚ Howard Taylor Ricketts. The unicellular aerobic gram negative non-motile‚ non-spore forming‚ coccobacilli bacterium are 0.3-0.5 x 0.8-2.0 um. It is in the family Rickettsiaceae and order Rickettsiales of the α-Proteobacteria. It is a unicellular microorganism that lacks a distinct nucleus and membrane- bound organelles‚ while it is a three-layered cell wall and its outer

Pathogens have evolved and have various ways to transmit from one host to another. Transmission from one host to another is one way how microbes are able to survive in a long run and maintain their species survivability. If pathogens were not able to transmit‚ upon the death of the host‚ the microbes would not have any means to infect another host. Some pathogens have only one mean of transmitting whereas there are other pathogens that can be transmitted via many different methods. In general‚ there

Salmonella is a bacillus bacteria from the Enterobacteriaceae family which can be devided into two species which is Salmonella bongori and Salmonella enterica‚ and another six subspecies can be divided from the species of Salmonella enterica‚ which are enterica‚ salamae‚ arizonae‚ diarizonae‚ houtenae and indica. Salmonellae are found globally in all types on animals‚ and also in the environment. From an article researched‚ proposed by C. Wray and A. Wray‚ it is stated that one of the main habitat

My partner and I were given unknown number 3 in the laboratory. After performing various tests over the course of a few weeks on our unknown‚ we came to the conclusion that our unknown organism is Klebsiella pneumoniae (K. pneumoniae). K. pneumoniae is a gram negative bacillus shaped microorganism. We observed that K. pneumoniae is a nonmotile organism. We performed multiple tests on our unknown culture‚ therefore we are very confident that it is correctly identified. We identified that K. pneumoniae

Antibacterial action of the irrigants against Enterococcus faecalis in the root canal The overall percentage reduction of E. faecalis inside the root canal after biomechanical procedures was presented in table1. All the irrigants significantly reduced bacteria in comparison with positive control group (P< 0.01). The average reduction of bacteria in the presence of E.galbie did not have any significant difference with 2.5% NaOCl‚ CHX 2%‚ CHX 0.2% and M.communis L. (P > 0.05). The average reduction

ABSTRACT Nature has been a source of medicinal agents for thousands of years and an impressive number of modern drugs have been isolated from natural sources Plants used for traditional medicine contain a wide range of substances that can be used to treat chronic as well as infectious diseases. Clinical microbiologists have great interest in screening of plants for antimicrobial activities and phytochemicals as potential new therapeutics. The use of plant extract for medical treatments is enjoying

Introduction: Antimicrobial agents are chemicals that are used against bacteria. There are many such agents available. Because there are many different situations where bacterial control is important‚ no antimicrobial agent is effective in all situations. For example‚ you wouldn’t use the same compound to fight an ear infection as you would use to sterilize surfaces in an Operating room. The situations are completely different. In one case‚ you are trying to assist the body to fight off an internal
