Millennia later, the apparent descendants of this pathogen would unleash vicious pandemics that claimed millions of human lives, including the 6th-century Justinian plague and the 14th-century Black Death. In tracing the backstories of diseases like plague, this new research highlights the importance of looking not just at ancient human remains, but also the animals around them, the authors say. Most human pathogens have zoonotic origins, a...

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...

Start Slideshow When it comes to navel orangeworm control in your pistachio, almond, and walnut orchards in the fall and winter, sanitation is the key. While that sounds simple — destroy any mummy nuts — the truth is there are a lot of factors that can make a simple solution complicated. Advertisement These complications have financial implications, as labor to help clean up the orchard can be costly and time-consuming. These complications can also come in the form of weather issues that make postharvest cleanup more of a challenge. “Although this is a proven practice, we still see some growers are not doing this practice, for whatever reason. Sometimes, it is difficult to do mummy sanitation due to the rainfall in the winter, or due to the heavy ground in some orchards. But it is important to plan in advance considering these factors. Sanitation can be done at any time between October and Feb. 1,” Jhalendr...
