Influenza virus infection in guinea pigs raised as livestock, Ecuador.

Leyva-Grado VH, Mubareka S, Krammer F, Cárdenas WB, Palese P - Emerging Infect. Dis. (2012)

Bottom Line: To determine whether guinea pigs are infected with influenza virus in nature, we conducted a serologic study in domestic guinea pigs in Ecuador.Detection of antibodies against influenza A and B raises the question about the role of guinea pigs in the ecology and epidemiology of influenza virus in the region.

ABSTRACT
To determine whether guinea pigs are infected with influenza virus in nature, we conducted a serologic study in domestic guinea pigs in Ecuador. Detection of antibodies against influenza A and B raises the question about the role of guinea pigs in the ecology and epidemiology of influenza virus in the region.

Three regions of Ecuador where guinea pig serum samples were obtained: Cuenca, Guayaquil, and Manabi. The country is bordered by Colombia to the north, Peru to the east and south, and the Pacific Ocean to the west. Cuenca is located in the Andes; the average annual mean temperature is 14.7°C, and the average annual relative humidity is 85%. Guayaquil is located at the head of the Gulf of Guayaquil; the mean temperature is 26.1°C, and relative humidity is 74%. The Manabí region is located on the Pacific Ocean coast; the mean temperature is 25.9°C, and relative humidity is 79%.

The country is bordered by Colombia to the north, Peru to the east and south, and the Pacific Ocean to the west. Cuenca is located in the Andes; the average annual mean temperature is 14.7°C, and the average annual relative humidity is 85%. Guayaquil is located at the head of the Gulf of Guayaquil; the mean temperature is 26.1°C, and relative humidity is 74%. The Manabí region is located on the Pacific Ocean coast; the mean temperature is 25.9°C, and relative humidity is 79%.

Mentions: We obtained serum samples from 40 guinea pigs from 3 different regions of Ecuador (Figure 1), 20 from Cuenca and 10 each from Guayaquil and the Manabí region. Cuenca is located in the Andes region, 2,500 m above sea level; it is one of the main producers of guinea pig meat. Guayaquil, the most populated city in Ecuador, is located at the head of the Gulf of Guayaquil on the Pacific Ocean. The Manabí region is located in western Ecuador on the Pacific Ocean coast. Serum samples were collected from adult guinea pigs that we purchased from local farms (Cuenca), where they had been raised as livestock, or from live animal markets (Guayaquil and Manabí). The samples were collected by heart puncture under general anesthesia (combination of ketamine and xylazine). Animals were euthanized after samples were obtained.
