Abstract

Introduction: The lymphocytic choriomeningitis virus is an Old World arenavirus that infects Mus musculus, and can cause congenital hydrocephalus, chorioretinitis and multisystemic failure in transplant human recipients. Although the disease has not been clinically diagnosed in Colombia yet, there have been reports of infection with the Pichindé virus in rodents from Cauca and Valle del Cauca departments, and with the Guanarito virus in rodents from Córdoba department. Objective: To identify the lymphocytic choriomeningitis virus from Mus musculus captured in the municipality of Sincelejo. Materials and methods: We evaluated 80 samples of plasma by ELISA using antigen from lymphocytic choriomeningitis virus. Additionally, a nested RT-PCR was performed to seropositive and seronegative samples for the S-segment. Results: We found a 10% seroprevalence (8/80) and the viral genome was detected in 16 brain samples; the alignment (BLAST) and the phylogenetic analysis (MrBayes, version 3.2.2) confirmed the presence of the lymphocytic choriomeningitis virus. Conclusion: The results indicated that human infection with the lymphocytic choriomeningitis virus in humans could occur in the urban area of Sincelejo, although no cases have been reported so far.
