Disseminated Mycobacterium avium complex infection in an immunocompetent pregnant woman

BACKGROUND: Disseminated mycobacterium avium complex (MAC) occurs mainly in immunocompromised hosts, which is associated with abnormal cellular immunity. CASE PRESENTATION: A 26-year-old pregnant woman presented with fever and general weakness. Miliary lung nodules were noted on chest X-ray. Under the impression of miliary tuberculosis, anti-tuberculosis medication was administered. However, the patient was not improved. Further work-up demonstrated MAC in the sputum and placenta. The patient was treated successfully with clarithromycin-based combination regimen. CONCLUSION: This appears to be the first case of disseminated MAC in an otherwise healthy pregnant woman. Clinicians should be alert for the diagnosis of MAC infection in diverse clinical conditions

Sporadic<i>Salmonella enterica</i>serotype Javiana infections in Georgia and Tennessee: a hypothesis-generating study

SUMMARYFrom 1996 to 2004, the incidence ofSalmonellaJaviana infections increased in FoodNet, the U.S. national active foodborne disease surveillance programme. Contact with amphibians and consumption of tomatoes have been associated with outbreaks ofS. Javiana infection. To generate and test hypotheses about risk factors associated with sporadicS. Javiana infections, we interviewed patients with laboratory-confirmedS. Javiana infection identified in Georgia and Tennessee during August–October 2004. We collected data on food and water consumption, animal contact, and environmental exposure from cases. Responses were compared with population-based survey exposure data. Seventy-two of 117 identifiedS. Javiana case-patients were interviewed. Consumption of well water [adjusted odds ratio (aOR) 4·3, 95% confidence interval (CI) 1·6–11·2] and reptile or amphibian contact (aOR 2·6, 95% CI 0·9–7·1) were associated with infection. Consumption of tomatoes (aOR 0·5, 95% CI 0·3–0·9) and poultry (aOR 0·5, 95% CI 0·2–1·0) were protective. Our study suggests that environmental factors are associated withS. Javiana infections in Georgia and Tennessee.</jats:p
