| 영문 | secondary infection | 한글 | 이차감염 |
|---|---|---|---|
| 설명 | 어떤 병원체의 감염에 의하여 본인의 저항력이 약해졌을 때 몸의 다른 부위로 전이하여 다시 감염을 일으키는 것. 병원체가 인체에 침입하여 특정한 기관이나 조직에서 병원체가 증식하고, 그곳에 특유의 병터를 일으키는 것이 1차감염 또는 초감염이다. 이 1차감염의 병터의 병원체가 혈관-림프관-기관-소화관-요관 등의 길을 따라 같은 기관의 다른 부위나 다른 기관으로 운반되어 감염을 일으킨다. 따라서 1차감염에 의하여 충분한 면역이 될 경우에는 2차감염이 일어나지 않는다. 예를 들어, 유행성 감기에 걸렸을 때 세균에 의한 폐렴이 뒤따르는 경우를 이른다. 폐렴균, 화농알균, 대장균 따위가 있다. |

| Streptococcus lactis R factor | 10-formylpteroic acid;a folic acid factor for certain bacteria. Synonym: SLR factor, Streptococcus lactis R factor. (05 Mar 2000) |
|---|---|
| Streptococcus M antigen | The somatic antigen associated with virulence and type specificity of group A streptococci. Synonym: M protein. (05 Mar 2000) |
| Streptococcus mitis | A species found in the human mouth, throat, and nasopharynx; ordinarily, it is not considered to be pathogenic, but this organism may be recovered from ulcerated teeth and sinuses and from blood and heart lesions in cases of subacute endocarditis. (05 Mar 2000) |
| streptococcus mutans | A polysaccharide-producing species of streptococcus isolated from human dental plaque. (12 Dec 1998) |
| streptococcus oralis | A species of gram-positive, coccoid bacteria that is numerous in the mouth and throat. It is a common cause of endocarditis and is also implicated in dental plaque formation. (12 Dec 1998) |
| streptococcus phages | Viruses whose host is streptococcus. (12 Dec 1998) |
| streptococcus pneumoniae | A gram-positive organism found in the upper respiratory tract, inflammatory exudates, and various body fluids of normal and/or diseased humans and, rarely, domestic animals. (12 Dec 1998) |
| streptococcus pyogenes | A species of gram-positive, coccoid bacteria isolated from skin lesions, blood, inflammatory exudates, and the upper respiratory tract of humans. It is a group a haemolytic streptococcus that can cause scarlet fever and rheumatic fever. Unlike the docile strains that cause strep throat, however, the virulent strains penetrate deep into the body, with catastrophic results. It has been demonstrated that invasive streptococcus a infections can trigger a toxic shock syndrome, chew up muscle (myositis), or destroy the sheath that covers the muscle (fasciitis, necrotizing). (12 Dec 1998) |
| Streptococcus salivarius | A species found in the human mouth, throat, and nasopharynx. (05 Mar 2000) |
| streptococcus sanguis | A gram-positive organism found in dental plaque, in blood, on heart valves in subacute endocarditis, and infrequently in saliva and throat specimens. L-forms are associated with recurrent aphthous stomatitis. (12 Dec 1998) |
| streptococcus sobrinus | A species of gram-positive, coccoid bacteria isolated from the human tooth surface. Strains have been shown to be cariogenic in experimental animals and may be associated with human dental caries. (12 Dec 1998) |
| streptococcus suis | A species of streptococcus isolated from pigs. It is a pathogen of swine but rarely occurs in humans. (12 Dec 1998) |
| Streptococcus uberis | A species causing mastitis in cattle. (05 Mar 2000) |
| Streptococcus viridans | A name applied not to a distinct species but rather to the group of alpha-haemolytic streptococci as a whole; viridans streptococci have been isolated from the mouth and intestines of humans, the intestines of horses, the milk and faeces of cows, milk and milk products, and the sputum and lungs in cases of primary atypical pneumonia. (05 Mar 2000) |
| Streptococcus zooepidemicus | Former name for Streptococcus equi zooepidemicus. (05 Mar 2000) |
