Even making more subtle changes to the landscape—such as digging pools, opening irrigation ditches, and discarding tires—create new niches for vectors, animals that are capable of carrying human disease. Insects carry about one hundred different human diseases, which are called arboviruses (arthropod...
Microbes are also exploited by people in biotechnology, both in traditional food and beverage preparation, and in modern technologies based on genetic engineering. However, pathogenic microbes are harmful, since they invade and grow within other organisms, causing diseases that kill millions of people,...
This chapter describes the mechanisms by which a microbe causes disease. Many microbes release substances into the body as they multiply. Some of these substances are formed as part of the microbe's strategy, because they interfere with host defenses. These substances are called toxins and they ...
While we have passed several significant milestones, we are still far from the goal of a sustainable agricultural system beyond our planet Regolith-based agriculture (RBA) should be a component of sustainable agriculture solutions beyond Earth, one which can also provide insight into plant growth in...
Studies on the gut microbiota of animals have largely focused on vertebrates. The transmission modes of commensal intestinal bacteria in mammals have been well studied. However, in gastropods, the relationship between gut microbiota and hosts is still po
Some eukaryotic microbes are harmful to humans while others are not. Why are some harmful and some not harmful?Eukaryotic Microbes:In the most general terms, we can divide living beings into two big groups, prokaryotes and eukaryotes. Prokaryotes, which inclu...
Microbes are a vital component of fertile soil. In the human body, microorganisms make up the human microbiota, including the essential gut flora. The pathogens responsible for many infectious diseases are microbes and, as such, are the target of hygiene measures. ...
Luckily, the vast majority of these entities cause us no harm. Many even improve our health! But of among this diverse set of microbes, some cause diseases like pneumonia, skin infections, and hepatitis. Within this set of bugs (called pathogens), a few seem to directly hack into ...
which therefore cannot be controlled by them.” The US government’s Interagency Task Force states: “Many other pathogens including the bacteria that cause tuberculosis and gonorrhea, human immunodeficiency virus, the fungi that cause yeast infections, and the parasites that cause malaria – are ...
