tb gold test :: Article Creator Scientists Develop A TB Test & Find A Genetic Vulnerability In Resistant Strains A rapid diagnostic test for tuberculosis (TB) has been approved for the first time by the World Health Organization (WHO). The assay can identify the tuberculosis-causing pathogen Mycobacterium tuberculosis in sputum samples within a few hours. Tuberculosis is a primary cause of death by infectious disease worldwide. The disease is estimated to kill over one million people every year, and is a huge socio-economic burden, particularly in low- and middle-income countries. "High-quality diagnostic tests are the cornerstone of effective TB care and prevention," said Dr. Rogerio Gaspar, WHO Director for Regulation and Prequalification. "Prequalification paves the way for equitable access to cutting-edge technologies, empowering countries to address the dual burden of TB and drug-resistant TB." M. Tuberculosis c...

The Bubonic Plague struck Europe and Asia in the fourteenth century. In October 1347, 12 ships from the Black Sea docked at the Sicilian port of Messina and so the plague arrived in Europe.
Throughout the history of human civilisation, several pandemics have occurred and left a lasting impact. Besides Ebola virus and HIV AIDS, the coronavirus pandemic is the most devastating medical disaster of the twenty-first century. However, history has shown how our ancestors faced similar epidemics. One such pandemic that continues to find its mention even today is the Bubonic plague also known as the Black Death. The Bubonic Plague struck Europe and Asia in the fourteenth century. In October 1347, 12 ships from the Black Sea docked at the Sicilian port of Messina and so the plague arrived in Europe. People who gathered on the docks witnessed a horrifying sight as most sailors aboard the ships were dead. Those who were still alive were critically ill and covered in black boils that oozed blood and pus. To protect its population, the Sicilian authorities immediately ordered the fleet of so-called "death ships" out of the harbor. However, it was too late as the infection was highly contagious and already left its carriers in the local population. The Black Death ravaged through Europe over the next five years, and killed more than 20 million people in the continent which accounted for nearly one-third of the continent's population.
According to the World Health Organisation, the bubonic plague is caused by bacteria called Yersinia pestis that is mainly found in rodents and their fleas. The name of the disease stems from the symptoms it causes which is painful, swollen lymph nodes also known as 'buboes' in the groin or armpit.
So how did such a contagious pandemic go away?
There were rudimentary and even superstitious treatments practiced by the physicians of the time. Practices that were dangerous as well as unsanitary like bloodletting and boil-lancing were performed on patients. Some superstitious practices included burning of aromatic herbs and bathing in rosewater or vinegar. Lack of scientific development also meant that Black Death was considered as a kind of divine punishment for sins against God. Hence this also led many people to delve into brutal practices purging their communities of rebels and other criminals.
However, some sense did prevail among the medical experts of those days who understood that the disease was spreading through proximity. With this discovery, the concept of quarantine was introduced. According to History, officials in Venetian-controlled port city of Ragusa decided to keep newly arrived sailors in isolation until they could prove they were not carrying the infection. Sailors were asked to stay on their ships for 30 days, which under the Venetian law came to be known as a trentino. The law was later modified and the compulsory isolation was increased to 40 days known as quarantino. This is how the word quarantine was coined and its practice was adopted in the Western world. The year 2020 saw a revival of this practice and usage in everyday language as coronavirus pandemic spread throughout the world.

UNIVERSITY PARK, Pa. — An outbreak of the highly pathogenic avian influenza virus in poultry in 2014-15 resulted in the destruction of more than 50 million chickens and turkeys in the U.S., causing billions of dollars in economic loss. This animal disease outbreak — the worst in U.S. history — is one example of how devastating a foreign animal disease can be to animal agriculture and the country's economy. The resurgence of avian influenza in multiple states, including Pennsylvania, is once again bringing the importance of preventing animal diseases to the forefront, noted Suresh Kuchipudi, clinical professor of microbiology in Penn State's College of Agricultural Sciences. Exploring the emergence, spread and control of animal infectious diseases such as avian influenza was the focus of the inaugural Emerging Animal Infectious Disease Conference held Nov. 29-Dec.1, 2021, at Penn State. It was hosted by the College of Agricultural Sciences, the Pennsylvania Department of A...
dented can botulism :: Article Creator Three Canadians Sickened In France's Botulism Outbreak Are From Quebec: PHAC The Public Health Agency of Canada has confirmed that the three Canadians who fell ill in a botulism outbreak in France are from Quebec.
