Introduction:
Most of the migrants residing in Guadeloupe are from neighboring Caribbean islands, some of which are characterized by a high incidence of tuberculosis. The objective of this retrospective and observational study was to define the epidemiological characteristics of tuberculosis affecting migrant and native populations in Guadeloupe.
Methods:
We describe all cases of tuberculosis in Guadeloupe identified in these two populations between 1 July 2006 and 30 June 2011.
Results:
The incidence of TB among migrants in Guadeloupe was seven times higher than that in native subjects in 2010 (33.4 vs. 5.5 new cases/100,000 inhabitants). Tuberculosis affecting the migrant population was characterized by young age of the patients (42 vs. 55 years) and a significant proportion of co-infection by the human immunodeficiency virus (HIV) (47 vs. 14%, P<0.001). Among the patient population studied, the HIV infection increased the risk of developing severe tuberculosis (adjusted odds ratio: 2.9; 95%CI: 1.2-6.8). Moreover, HIV infection was also a risk factor for death where the infection was not controlled (CD4 count <200 units per microliter; adj risk ratio: 3.9; 1.2-12.4).
Conclusion:
This study shows that the migrant population in Guadeloupe is at increased risk of tuberculosis and should be considered as a priority target for tuberculosis control program.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
