Campylobacter Rectus
''Campylobacter rectus'' is a species of '' Campylobacter''. It is implicated as a pathogen in chronic periodontitis, which can induce bone loss. This motile bacillus is a Gram negative, facultative anaerobe. ''C. rectus'' is associated with hypertension together with ''Prevotella melaninogenica'' and ''Veillonella parvula ''Veillonella parvula'' is a strictly anaerobic, Gram-negative, coccus-shaped bacterium in the genus ''Veillonella''. It is a normal part of the oral flora but can be associated with diseases such as periodontitis and dental caries as well as var ...''.

Campylobacter
''Campylobacter'' (meaning "curved bacteria") is a genus of Gram-negative bacteria. ''Campylobacter'' typically appear comma- or s-shaped, and are motile. Some ''Campylobacter'' species can infect humans, sometimes causing campylobacteriosis, a diarrhoeal disease in humans. Campylobacteriosis is usually self-limiting and antimicrobial treatment is often not required, except in severe cases or immunocompromised patients. The most known source for ''Campylobacter'' is poultry, but due to their diverse natural reservoir, ''Campylobacter'' spp. can also be transmitted ''via'' water. Other known sources of ''Campylobacter'' infections include food products, such as unpasteurised milk and contaminated fresh produce. Sometimes the source of infection can be direct contact with infected animals, which often carry ''Campylobacter'' asymptomatically. At least a dozen species of ''Campylobacter'' have been implicated in human disease, with ''C. jejuni'' (80–90%) and '' C. coli'' (5-10%) b ...

Chronic Periodontitis
Chronic periodontitis is one of the seven categories of periodontitis as defined by the American Academy of Periodontology 1999 classification system. Chronic periodontitis is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues that is caused by the accumulation of profuse amounts of dental plaque. Periodontitis initially begins as gingivitis and can progress onto chronic and subsequent aggressive periodontitis according to the 1999 classification. Diagnosing chronic periodontitis is important in its early stages to prevent severe and irreversible damage to the protective and supportive structures of the tooth. However, due to chronic periodontitis being a painless progressing disease, few patients will seek dental care in the early stages. Mild to moderate chronic periodontitis can be managed by proper mechanical removal of the biofilm and calculus subgingivally. Full and effective oral hygiene and regular 3 monthly periodontal check ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram Negative
The gram (originally gramme; SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre the_temperature_of_Melting_point.html" "title="Melting_point_of_water.html" ;"title="Cubic_centimetre.html" ;"title=" Cubic centimetre">cm3], and at Melting point of water">the temperature of Melting point">melting ice", the defining temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water. However, by the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a ''gram'' as one one-thousandth of a kilogram (i.e., one gram is Scientific notation, 1×10−3 kg). The kilogram, as of 2019, is defined by the International Bur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such ...

Prevotella Melaninogenica
''Prevotella melaninogenica'' is a species of bacterium in the normal microbiota of the upper respiratory tract. It is an important human pathogen in various anaerobic infections, often mixed with other aerobic and anaerobic bacteria. ''P. melaninogenica'' is an anaerobic, Gram-negative rod, named for its black colonies, and black pigment. ''P. melaninogenica'' is associated with hypertension together with ''Campylobacter rectus'' and ''Veillonella parvula''. Description ''P. melaninogenica'' are Gram-negative rod-shaped bacteria. They cannot survive in the presence of oxygen. They are not motile, and do not form spores. ''P. melaninogenica'' grow well on blood agar, where they form circular dark-colored colonies that darken over one to two weeks. History ''P. melaninogenica'' was originally described as ''Bacteroides melaninogenicus'' in 1921 by Wade Oliver and William Wherry at the University of Cincinnati as a new bacterium isolated from various sites of several different hu ...

Veillonella Parvula
''Veillonella parvula'' is a strictly anaerobic, Gram-negative, coccus-shaped bacterium in the genus ''Veillonella''. It is a normal part of the oral flora but can be associated with diseases such as periodontitis and dental caries as well as various systemic infections, including meningitis and osteomyelitis. It has also been isolated from women with bacterial vaginosis and has been associated with hypertension together with ''Campylobacter rectus'' and ''Prevotella melaninogenica''. ''V. parvula'' is unable to feed on carbohydrates, but can feed on lactate provided by ''Streptococcus'' species also found in the oral cavity. Specifically, ''Streptococcus mutans'' and ''V. parvula'' can form multispecies biofilms that lead to a lower susceptibility to antimicrobial treatments, resulting in periodontitis and dental carries. Antimicrobial susceptibility ''V. parvula'' bacteria are susceptible to and typically treated with metronidazole and penicillin in clinical reports. Other an ...

Campylobacterota
Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative. The Campylobacterota consist of few known genera, mainly the curved to spirilloid ''Wolinella'' spp., ''Helicobacter'' spp., and '' Campylobacter'' spp. Most of the known species inhabit the digestive tracts of animals and serve as symbionts (''Wolinella'' spp. in cattle) or pathogens (''Helicobacter'' spp. in the stomach, ''Campylobacter'' spp. in the duodenum). Many Campylobacterota are motile with flagella. Numerous environmental sequences and isolates of Campylobacterota have also been recovered from hydrothermal vents and cold seep habitats. Examples of isolates include ''Sulfurimonas autotrophica'', ''Sulfurimonas paralvinellae'', ''Sulfurovum lithotrophicum'' and ''Nautilia profundicola''. A member of the phylum Campylobacterota occurs as an endosymbiont in the large gills of the deepwater sea snail ''Alviniconcha hessleri''. The Campylobacterota found at deep-sea hydrothermal vents ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
