“…In this study, the prevalence of antibodies against some of the serovars reported in alpacas were high incomparison to those previously reported in cattle fromthe southern highlands (Cachata et al, 2008) and 4 alpaca herds from high elevation in the Department of Puno (Herrera Carpio et al, 2000). The positive reactions observed in alpaca and vicuña, particularly to the serovars icterohaemorrhagiae and pomona, are similar to those found in a survey of 600 alpacas from 30 herds in Canchis Province, Cusco Department, and the District of St. Lucia, Puno Department (Rosadio et al, 2003;Santos et al, 2009), as well as to the finding in a study conducted in llamas and vicuñas from several regions of Argentina (Llorente et al, 2002). The high prevalence, In Peru, leptospirosis is widely distributed in tropical and subtropical regions but has also been detected in the humid sierras of the southern highlands (Céspedes et al, 2006), and several pathogenic serovars including icterohaemorrhagiae, pomona and canicola have been isolated from humans and animals in the central sierra (Liceras de Hidalgo et al, 1989).…”

“…Leptospirosis is endemic in many countries, including the USA [83][84][85]. In Argentina, seroprevalence of the disease varies between 47.3% and 96.2% in llamas, 0% and 13% in guanacos, and 9% and 62.8% in vicunas.…”

“…The presence of seropositive wild camelids (guanacos and vicuna) is particularly important from an epidemiological perspective. The most frequently encountred serovars were copenhageni (serogroup Icterohaemorrhagiae) and castellonis (serogroup Ballum) [84]. Alpacas were shown to react to L. interrogans serovar after vaccination.…”

Infectious causes of reproductive loss in camelids

et al. 2006

View full text Add to dashboard Cite

Reproductive losses in camelids are due to infertility, pregnancy loss, udder diseases and neonatal mortality caused by a variety of infectious diseases. Uterine infection and abortion represent the major complaint in camelid veterinary practice. The major infectious organisms in endometritis and metritis are E. coli and Streptococcus equi subspecies zooepidemicus. Abortion rates due to infectious diseases vary from 10% to more than 70% in some areas. Leptospirosis, toxoplasmosis and chlamydiosis have been diagnosed as the major causes of abortion in llamas and alpacas. In camels, brucellosis and trypanosomiasis represent the major causes of infectious abortion in the Middle East and Africa. Mastitis is rare in South American camelids. The prevalence of subclinical udder infection in camels can reach very high proportions in dairy camels. Udder infections are primarily due to Streptococcus agalactiae and Staphylococcus aureus. Neonatal mortality is primarily due to diarrhea following failure of passive transfer and exposure to E. coli, rotavirus, coronavirus, Coccidia and Salmonella. This paper reviews the etio-pathogenesis of these causes of reproductive losses, as well as the major risk factors and strategies to prevent their occurrence.

“…Los resultados evidencian seroreacciones en alpacas y vicuñas, particularmente a los serovares icterohaemorrhagiae y pomona en tasas similares identificadas en alpacas de la provincia de Canchis, Cuzco y Santa Lucía, Puno (Rosadio et al, 2003; Santos et al, 2009) y a los CSA domésticos y silvestres de varias regiones de la Argentina (Llorente et al, 2002). La alta prevalencia, particularmente al serovar pomona en las vicuñas muestreadas en el estudio, difiere de lo detectado en 208 vicuñas de la reserva de Salinas y Aguada Blanca (Ortega et al, 2009).…”

RESUMENSe realizaron estudios serológicos en 793 alpacas y 195 vicuñas de comunidades campesinas de los departamentos de Huancavelica y Ayacucho, Perú, para detectar anticuerpos específicos para cinco serovares patogénicos (icterohaemorrhagiae, pomona, canicola, wolfii y ballum) mediante la prueba serovar específica de microaglutinación. Se encontró que 89.6% de las alpacas y 77.4% de las vicuñas eran seropositivas a uno o más serovares. En alpacas, los anticuerpos tuvieron títulos de 1:100 hasta 1:1600, mayormente con los serovares icterohaemorrhagiae (43.4%) y pomona (37.8%); en tanto que en las vicuñas se obtuvo títulos de 1:100 hasta 1:400, reaccionando similarmente a icterohaemorrhagiae (69.2%) y pomona (8.2%). Solamente las alpacas mostraron títulos positivos a los serovares canicola (7.8%) y wolfii (0.6%). Los resultados indican que los animales han estado expuestos a por lo menos 4 de los 5 serovares estudiados y que las alpacas, por los altos títulos, evidencian historia de infección reciente a los serovares icterohaemorrhagiae y pomona. Palabras clave: L. icterohaemorrhagiae, L. pomona, alpaca, vicuña, leptospirosis ABSTRACTA serologic study was conducted on 793 alpaca and 195 vicuña sera samples collected in Huancavelica and Ayacucho departments in Peru to detect specific antibodies against five pathogenic leptospira serovars (L. icterohaemorrhagiae, L. pomona, L. canicola, L. wolfii and L. ballum) by the microaglutination test. The survey revealed that 89.6% of the alpacas and 77.4% of vicuñas were positive to one or more serovars. In alpacas, the titers varied from 1:100 to 1:1600 reacting mainly to L. icterohaemorrhagiae (43.4%) and L. pomona (37.8%), whereas titers among vicuñas varied from 1:100 to 1:400 reacting
