NORIEGA R, L. Miguel et al. Listeria monocytogenes: Report of a rise in pregnant women and literature review. Rev. chil. infectol. [online]. 2008, vol.25, n.5, pp. 342-349. ISSN 0716-1018. http://dx.doi.org/10.4067/S0716-10182008000500004.
Listeria monocytogenes, rare pathogen in the general population, causes serious infections in patients at the extreme ages of life, pregnant woman, and those with immunosuppression. The clinical manifestations are essential to suspect the disease in patients at risk, allowing an early prescription of antimicrobial therapy, before the results of the cultures are available. Clinical course and prognosis depends on how early treatment is started and, in pregnant women, the gestational age. In Clínica Alemana, at Santiago, we detected a 15 fold rate rise of neonatal listeriosis between year 2007 and 2008. Ten cases were diagnosed between January and July 2008 and the seven cases occurring in pregnant women are reported here. All these patients were in their first pregnancy, which could be associated with similar lifestyle and food habits. Considering this new epidemiological scenario, it is important to educate the population, and to conduct an epidemiological study in order to determine the national situation of Listeria monocytogenes infection.
