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...

Is tuberculosis contagious?
Tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis. It affects the lungs, but the effects are not limited to this organ. TB can affect any part of the body such as your kidneys, brain and more, as per the US Centers for Disease Control and Prevention (CDC). If left untreated, it can lead to lethal consequences.
Dr Nayar shares that TB is contagious. "Though it can affect any organ of the body, it primarily affects the lungs and respiratory system. TB can spread through a cough or sneeze of the infected person (airborne transmission), and it can be transmitted from an infected person to an uninfected person.
TB is caused by the bacterium Mycobacterium tuberculosis, which spreads through the air and primarily affects the lungs and, in some cases, spreads to other parts of the body as well, he adds.
Signs and symptoms of tuberculosis
The signs and symptoms of TB depend on the part of the body where the bacterium has attacked, but some of the common symptoms of TB are the following, as per the expert:
Coughing, often with sputum and blood
Chest pain
Weakness
Weight loss
Fever
Night sweats
The severity of these symptoms can significantly hinder an individual's quality of life and ability to perform daily activities.
Risk factors of tuberculosis
Some people infected with the tuberculosis bacterium may develop the disease immediately or within weeks. On the other hand, some people may get sick years later when their immune system becomes weak after another underlying reason. As per the expert, the following can increase your risk:
Air pollution
People with a weak immune system
Smoking
Alcohol
Malnutrition
Low BMI
People with HIV
Close contact with a TB-infected person
Diabetics
Furthermore, overcrowding, poor ventilation, and inadequate healthcare access contribute to the spread and prevalence of TB.

Prevention tips
The best way to prevent TB is to get diagnosed and treated early. The methods include keeping your immune system healthy and avoiding contact with those who have active TB, improving indoor ventilation, maintaining self-hygiene, wearing masks when necessary, and leading a healthy lifestyle – eating healthy and exercising regularly, which will help in keeping your immunity strong, advises Dr Nayar.
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...

Other tourists from the U.S., Ireland, Germany and Spain were among those sickened. One patient, who was not from Canada, has died. France's public health agency is leading the investigation...
