Identificación molecular de leptospira icterohemorrágica en roedores y aguas residuales en el sector sur del cantón Machala.

Abstract

Introduction: This disease is caused by pathogenic bacteria of the genus Leptospira, and can be fatal if not treated immediately (1). This pathology has an estimate of more than one million severe cases per year and a mortality rate of 5% to 20%. (2). Worldwide, leptospirosis is an endemic and re-emerging zoonotic infection with high prevalence. Objective: To identify the incidence of leptospira icterohemorrhagica in rodents and wastewater using PCR laboratory technique in the southern sector of the city of Machala. Methodology: This work is a cross-sectional study because it was carried out in a short period of time, proceeding with the taking of samples in a certain time, to look for the presence or absence of Leptospira. Results: The results obtained were negative, the samples analyzed from rodents did not show the presence of Leptospira. This finding indicates a low prevalence of the bacteria in the rodent population in the investigated area. Conclusion: It is concluded that the dry conditions experienced in the study environment during sample collection are likely to have had a significant impact on the absence of the bacteria, therefore although the goal of creating an epidemiological map to identify the presence of Leptospira has not yet been achieved, this research provides important information on the current distribution of bacteria in the area and emphasizes the importance of conducting further research in a variety of climates and time periods.
