Pathogenic bacteria are bacteria that can cause disease. This article deals with human pathogenic bacteria. Although most bacteria are harmless or often beneficial, some are pathogenic, with the number of species estimated as fewer than a hundred that are seen to cause infectious diseases in humans. By contrast, several thousand species exist in the human digestive system.
Pathogenic bacteria can be spread through a human population in a range of ways. Air, water, and soil are all common vectors, and people may also pass bacteria directly to each other through physical contact.
Bacteria are all around us, in the air, on objects and normally found in and on the human body. When bacteria is on the human body in the absence of disease, it is called a colonizer. However, people can get infected from pathogenic bacteria from food, water, abrasions and other wounds and even from ...
Pathogenic bacteria also cause infections such as tetanus, typhoid fever, diphtheria, syphilis, and leprosy. Bacteria can often be killed by antibiotics, which are usually designed to destroy the cell wall. This expels the pathogen's DNA, making it incapable of producing proteins and causing the bacteria to die.
While most species of bacteria are harmless, and others beneﬁcial for us, there are a number of disease-causing bacteria, which are called "pathogenic bacteria." Pathogenic bacteria can contribute to many worldwide diseases, including tuberculosis, cholera, anthrax, leprosy, the bubonic plague, pneumonia, and food-borne illnesses.
Bacteria are present all around us. A few of them are beneficial, while others are pathogenic. The word pathogenic denotes the ones that are disease-causing. The following HealthHearty article provides you information on bacteria and help you learn their names through the given list.
As nouns the difference between bacteria and pathogen is that bacteria is or bacteria can be (dated|medicine) an oval bacterium, as distinguished from a spherical coccus or rod-shaped bacillus while pathogen is (pathology|immunology) any organism or substance, especially a microorganism, capable of causing disease, such as bacteria, viruses, protozoa or fungi microorganisms are not considered ...
When combined with the Streptococcus dentisani - believed to be an oral probiotic, which stimulates the growth of good bacteria - the polyphenols were even better at inhibiting the pathogenic bacteria.
— Jason Pontin, WIRED, "The 19th-Century Crank Who Tried to Tell Us About the Microbiome," 15 June 2018 Overall, the researchers found that more than a third of the mice carried at least one potentially pathogenic bacterium, while about a quarter of them had bacteria with at least one resistance gene.
Infection is the invasion of the host by microorganisms, which then multiply in close association with the host's tissues. Infection is distinguished from disease, a morbid process that does not necessarily involve infection (diabetes, for example, is a disease with no known causative agent). Bacteria can cause a multitude of different infections, ranging in severity from inapparent to ...
