Yersinia

Yersinia pestis (Y. pestis), a gram-negative, non-motile facultative intracellular bacterium is responsible for the bubonic plague in humans (Smiley 2008). The bacterium uses the Rodent flea Xenopsylla cheopis as a vector to gain entry into a new host. (Butler 2009). The bacterium forms of an aggregative biofilm on the spicules of the proventriculus in the flea (Butler 2009). This blockage on the proventriculus causes the flea to behave as if it is starving continuously biting and try to feed

Identification and Prevention of What Makes Life “Nasty, Brutish, and Short” Plague is caused by the bacterium bacillus Yersinia pestis, and is carried by rodents, fleas, and mammals. Plague takes three forms: bubonic, pneumonic, and septicemic. Bubonic plague affects the lymph glands, while the pneumonic and septicemic forms affect the lungs and the blood. Today, plague can be prevented by antibiotics and strict public health measures. Three methods of controlling carriers involve sanitizing

Yersinia pestis - Bacteria Virulence and Symptoms Yersinia pestis appeared fairly early in history and is still prevailing today. Humans have come in contact with this bacterium in massive outbreaks throughout history, including the most famous Black Death of the 14th century. From the lack of knowledge of the bacteria and its ability to infect populations rapidly, the human race has suffered immensely. The bacterium is specialized with specific plasmids, Yersinia outer proteins as well as other

The Plague and the Yersinia Pestis Bacteria Introduction: The bacteria Yersinia Pestis is the cause of the black plague. Y. Pestis was discovered by Alexandre Yersin in 1849. The plague was the cause of one of the world's most horrific epidemics in the entire world. The plague is an infectious disease that first appeared in 1347 in China and made its way to Asia and then the Black Sea. The Black Plague has caused death to about 75 million lives. The plague is a deadly bacterial infection that can

Yersinia pestis – Gerneal Infection, Symptoms, Diagnosis, and Treatment Yersinia pestis, the culprit behind the infamous Black Death, spread by rat fleas, has cast a shadow over human civilization, taken the lives of countless peasants and nobles alike like a violent brute who murders invariably. There are three major forms of infection stages, the bubonic plague, the septicemic plague, and the pneumonic plague (primary and secondary), all are lethal if not treated with proper antibiotics. Due

East Smithfield was excavated in the 1980s and, thanks to the 2,400 bodies recovered from the graveyard, scientists were able to reconstruct the genome from the bacterium that caused the bubonic plague, Yersinia pestis (Callaway). Years before this discovery, Alexandre Yersin linked Yersinia pestis (Y. pestis) to the bubonic plague; many scientists then surmised that the pathogen was behind not only the Black death, but also a myriad of earlier mass pandemics

Yersinia Pestis is a bacterial infection responsible for the deaths of millions of people starting in the 1300’s and still continues to infect people to this day. This bacterial strain is the basis of three very serious and potentially fatal diseases: the Bubonic plague, the Pneumonic Plague, and the septicemic Plague. The difference between the plagues is primarily the location of the infection but the symptoms also vary as well. The bubonic plague attacks the Lymphatic system whereas the Pneumonic

Evolutionary Insights and Effective Invasive Steps of Yersinia spp. Author: Malvi Prakash Golwala (U53409030) Email address: malviprakash@mail.usf.edu Course name: Cellular Microbiology Course number: BSC6932.079F15 Semester year: 2015 Abstract Yersinia is a gram-negative bacteria causing plague pandemics in humans. They are facultative intracellular organisms that can very efficiently survive and replicate inside cells (1). They cause fatal plague and have destroyed millions of lives

Yersinia Pestis and the body’s response: The Cellular Level Yersinia pestis, is well known for being the cause of the bubonic plague; the cause of the black death that plagued medieval Europe. What is not nearly as well known, is that there are actually three different forms a Y. pestis infection can take: pneumonic, septicemic, and bubonic. How Y. pestis infects the body and why it is so deadly are also largely unknown with regards to most people’s knowledge of the subject. Much research has gone

Infectious diseases bring wreckage to some of the poorest and weakest communities in our country along with others. At the time, the Yersinia Pestis disease was only being found in some parts of the world, mainly Africa, Asia, and South America. Today our generation has many repellents that prevent any type of contact with fleas, mosquitos, moths, and more. However, during the mid 1800’s many were not guaranteed such a luxury; it was as simple to catch the disease if individuals were bitten by any
