    We conducted a 16S rRNA nested PCR for the genus Ehrlichia and Ehrlichia spp. with blood samples from 30 ill dogs in Chile. Phylogenetic analysis was performed by using groESL gene amplification. We identified Anaplasma platys as 1 of the etiologic agents of canine ehrlichiosis.

    Asociación temporal entre la circulación de virus respiratorios y hospitalizaciones por enfermedad de Kawasaki
    (Sociedad Chilena de Infectologia, 2021) Aguirre, Daniela; Cerda, Jaime; Perret, Cecilia; Borzutzky Schachter, Arturo; Hoyos-Bachiloglu
    © 2021, Sociedad Chilena de Infectologia. All rights reserved.Background: The etiology of Kawasaki disease (KD) is unknown. It is believed that viral infections could trigger the disease in susceptible patients. Aim: To study the temporal association between the circulation of respiratory viruses and KD hospitalizations in the Metropolitan Region (MR), Chile, between 2010-2017. Methods: Ecologic study consisting of a review of KD cases in children under 18 years of age based on hospital discharges. The circulation of respiratory viruses was analyzed using the report of the metropolitan surveillance network. Moving averages for KD (MAKD) and respiratory viruses (MARV) were used. Results: 14,902 cases of respiratory virus infections were recorded between 2010-2017. A direct correlation was found between MARV-respiratory syncytial virus (RSV) of one month and year and MAKD of the subsequent month (correlation coefficient (ρ) = +0.441; p < 0.001). A similar association was found for MARV-influenza A (FLU A) (ρ = + 0.362; p < 0.001). MARV-influenza B (FLU B) and MARV-metapneumovirus (MPV) had direct correlations with MAKD (ρ = +0.443; p < 0.001 and ρ = +0.412; p < 0.001, respectively), being FLU B contemporary in month and year with KD, and MPV presenting a one-month lag. Conclusion: There is a direct temporal correlation between RSV, FLU A, FLU B and MPV circulation and KD in children from RM, Chile.

    Fuente de infección de Bordetella pertussis en lactantes hospitalizados por coqueluche
    (SOC MEDICA SANTIAGO, 2011) Perret, Cecilia; Viviani, Tamara; Pena, Anamaria; Abarca, Katia; Ferres, Marcela
    Background: Despite pertussis vaccination, very young infants have the highest rates of morbidity and mortality caused by the microorganism. Aim: To determine the source of Pertussis infection in infants aged six months or less in Chile. Material and Methods: Twenty six household contacts of 10 young infants hospitalized with confirmed Pertussis were studied for the presence of Bordetella Pertussis by polymerase chain reaction (PCR). Clinical and demographic data were analyzed. Results: Respiratory symptoms were present in 20 (77%) contacts, being cough the most common. Pertussis cases were identified in every household and in 18 (72%) of the household members. Four members with B.pertussis were asymptomatic. Source of infection was identified in 80% (8/10) of the infant cases with ages ranging from 6 to 62 years. Half of primary cases had positive PR and their cough duration was significantly shorter compared to primary cases with negative PER. Conclusions: B. pertussis transmission to young infants occurred mainly within the household where adults are generally the source of the infection. Risk factors for infant infection are the same as in developed countries. Therefore, the same strategies, such as routine vaccination in adolescents and adults or cocoon strategy, will help to prevent this disease in infants. (Rev Med Chile 2011; 139: 448-454).
