1. Pathogenic bacteria

   Pathogenic bacteria are bacteria that can cause disease. This article focusses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. By contrast, several thousand species are part of the gut flora present in the digestive tract. The body is continually exposed to many species of bacteria, including beneficial commensals, which grow on the skin and mucous membranes, and saprophytes, which grow mainly in the soil and in decaying matter. The blood and tissue fluids contain nutrients sufficient to sustain the growth of many bacteria. The body has defence mechanisms that enable it to resist microbial invasion of its tissues and give it a natural immunity or innate resistance against many microorganisms. Pathogenic bacteria are specially adapted and endowed with mechanisms for overcoming the normal body defences, and can invade parts of the body, such as the blood, where bacteria are not normally found. Some pathogens invade only the surface epithelium, skin or mucous membrane, but many travel more deeply, spreading through the tissues and disseminating by the lymphatic and blood streams. In some rare cases a pathogenic microbe can infect an entirely healthy person, but infection usually occurs only if the body's defence mechanisms are damaged by some local trauma or an underlying debilitating disease, such as wounding, intoxication, chilling, fatigue, and malnutrition. In many cases, it is important to differentiate infection and colonization, which is when the bacteria are causing little or no harm. Caused by Mycobacterium tuberculosis bacteria, one of the diseases with the highest disease burden is tuberculosis, which killed 1.4 million people in 2019, mostly in sub-Saharan Africa. Pathogenic bacteria contribute to other globally important diseases, such as pneumonia, which can be caused by bacteria such as Streptococcus, Pneumococcus and Pseudomonas, and foodborne illnesses, which can be caused by bacteria such as Shigella, Campylobacter, and Salmonella. Pathogenic bacteria also cause infections such as tetanus, typhoid fever, diphtheria, syphilis, and leprosy. Pathogenic bacteria are also the cause of high infant mortality rates in developing countries.Most pathogenic bacteria can be grown in cultures and identifed by Gram stain and other methods. Bacteria grown in this way are often tested to find which antibiotics will be an effective treatment for the infection. For hitherto unknown pathogens, Koch's postulates are the standard to establish a causative relationship between a microbe and a disease.

Examples of pathogenic bacteria in a Sentence

1. Julie Churchill:

   If pet parents are insistent on feeding raw, I try to steer them toward raw pet foods that have undergone high-pressure pasteurization to decrease the risk of pathogenic bacteria.

2. Cath Rees:

   The main message I get is that they did not find any evidence of pathogenic bacteria on the sponges or brushes taken from a range of domestic settings and therefore there is no evidence that these items are a significant source of contamination in normal domestic settings, if there were some low levels of pathogens left on Cath Rees cloth, they are going to grow quite slowly( they grow optimally at body temperatures), so Cath Rees would not expect to see much growth of these, and this matched their results -- in wet condition there was some limited growth, in drying conditions the numbers either stayed the same or declined.

3. Robin Foroutan:

   We all have bacteria, yeasts and other types of microbes living in our digestive tracts and many strains of these actually provide a benefit — that's why fermented foods and probiotics are so healthy, but excessive sugar intake can throw off the balance leading to an overgrowth of normally occurring yeast and pathogenic bacteria. This can have a negative effect on our energy, skin, immune function, mood and many other consequences.
