1/5. pasteurella multocida chorioamnionitis from vaginal transmission.A 21 year old primigravida with a twin pregnancy developed pasteurella multocida chorioamnionitis. infection occurred at 27 weeks gestational age after prolonged rupture of membranes. The twin in the separate sac presenting proximal to the cervix suffered infection and died shortly after birth whereas the other twin was not infected. The bacterium is believed to have caused ascending infection from asymptomatic colonization of the vaginal tract.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/5. A rare case of chorioamnionitis by morganella morganii complicated by septicemia and adult respiratory distress syndrome.morganella morganii, a gram-negative bacterium, usually infects older patients with urinary catheters, but does not commonly affect pregnant women. In this report we present a case of chorioamnionitis caused by morganella morganii. The case was complicated by a life-threatening adult Respiratory Distress syndrome.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
3/5. Clinicopathologic considerations of fusobacteria chorioamnionitis.When sought by light microscopy in formalin-fixed tissue, fusobacteria are apparent in 7-18% of chorioamnionitis cases. Brown and Hopps bacterial staining characteristically visualizes their long, slender and filamentous forms. fusobacteria-like organisms in placentae have previously been associated with prematurity. Our findings indicate that perinatal infection with fusobacteria may cause neonatal death from prematurity, rather than from sepsis. In a study of 586 placentae, 14 specimens with chorioamnionitis and fusobacteria-like organisms were found. On the five occasions when microbiologic tests were made, fusobacteria were isolated. Prematurity of the newborns was associated with twelve of those placentae. Immunofluorescent labelling of the organisms is a helpful but incomplete means of diagnosis. Because fusobacteria antibodies are highly specific, they do not cross-react with other members of the genus Fusobacterium. A typical case is reported, in detail.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
4/5. Fusobacterium: anaerobic occult amnionitis and premature labor.Fusobacterium species are well established pathogens. Before the advent of effective anaerobic antimicrobial therapy, they were associated with prolonged, often fatal courses. Previously, fusobacterium had not been identified as a common perinatal pathogen. Three cases of occult amnionitis due to Fusobacterium are presented. review of five series of occult amnionitis revealed 23 cases. In seven (30.4%), Fusobacterium was isolated. In 14 (60.8%), an anaerobic species was isolated. The average gestational age of patients from whom anaerobes were grown was 29.0 weeks. Of those that grew no anaerobes, the average gestational age was 32.3 weeks (P less than .05). The overall rate of maternal febrile morbidity was 35%. Fusobacterium accounted for 50% of the febrile cases while accounting for only 30.4% of the total cases.- - - - - - - - - - ranking = 9keywords = bacterium (Clic here for more details about this article) |
5/5. Orogenital contact: a cause of chorioamnionitis?BACKGROUND: fusobacterium nucleatum and capnocytophaga species are common oral pathogens and infrequent causes of systemic infection in patients with compromised immunity or disrupted mucosal integrity. The isolation of both organisms from a clinical specimen suggests an oral source of infection. CASE: A 23-year-old black woman was admitted at 24 weeks' gestation in preterm labor. She subsequently developed signs of clinical chorioamnionitis, including fever, fetal tachycardia, and uterine tenderness. Bacteriologic studies of the amniotic fluid and subchorionic placental cultures yielded F nucleatum and capnocytophaga species. On review of the patient's history, a temporal relation was noted between orogenital contact and the onset of clinical infection. Thorough evaluation of the patient, including dental examination, did not reveal an obvious source of infection. However, significant periodontal disease was identified in her partner. CONCLUSION: The concomitant finding of these two organisms in the patient's amniotic fluid and a history of periodontal disease in her partner suggests that chorioamnionitis may have been due to an ascending infection after orogenital contact.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
