Exploratory serosurvey for antibodies to avian pathogens in backyard chickens from a satellite community of Jalapa City, Guatemala
Get PDFAn exploratory serosurvey was conducted to determine the presence of circulating antibodies to avian pathogens in backyard chickens from Los Achiotes (LAC), a satellite community of Jalapa City, located in eastern Guatemala. Blood samples from 51 adult chickens belonging to 51 households were taken and investigated for the presence of antibodies to Avian Influenza (AI), Newcastle Disease (ND), Infectious Bronchitis (IB), Infectious Bursal Disease (IBD), Mycoplasma gallisepticum (MG) and M. synoviae (MS). Antibodies for AI, ND, were investigated by Hemagglutination Inhibition, for IB and IBD by ELISA (BioChek脗庐) and for MG and MS by a rapid serum plate agglutination test. The cut-off point for positive titers was 1:4 for AI and ND and a 0.2 S/P ratio for IB and IBD. All sampled chickens were positive for concomitant antibodies to various pathogens. Over half of the chickens were positive reactors to antibodies to all six tested pathogens; about a third carried antibodies to five and the rest to four or three. The frequencies of positive reactors were: AI = 27 (53%); ND = 49 (96.1%); IB = 50 (98%); IBD = 51 (100%); MG = 45 (88%) and MS = 48 (94%). The results show that the dynamic population of backyard chickens in LAC could be a potential threat to backyard poultry, farm poultry, wild birds and human population. The need to develop interventions and policies following the One Health approach (animal health to achieve human health) is stressed
Adaptaci贸n y rendimiento de plantas aut贸ctonas de Guatemala en un sistema acuap贸nico
Get PDFSe determin贸 la adaptaci贸n y rendimiento de ocho variedades de plantas aut贸ctonas de Guatemala en un sistema acuap贸nico. Se utilizaron siete m贸dulos acuap贸nicos, con capacidad de 80 plantas y 25 organismos de tilapia nil贸tica (Oreochromis niloticus). Se incluyeron en el estudio, plantas de apazote (Dysphania ambrosioides), makuy (Solanum nigrescens), amarantos (Amaranthus sp.), bledo (A. cruentus), chipil铆颅n (Crotalaria longirostrata), chipil铆颅n mont茅s (C. vitellina) ayote (Cucurbita argyrosperma) y g铆录icoy (C. pepo). El periodo de evaluaci贸n fue de 60 d铆颅as. Se registr贸 la supervivencia (S), tama帽o (T), peso (P) y biomasa o rendimiento (B) de las plantas y los peces al inicio y al final del periodo experimental. Se observ贸 adaptaci贸n de siete de las ocho especies de plantas aut贸ctonas, a los m贸dulos acuap贸nicos experimentales. La variedad de planta con mayor crecimiento fue el ayote, seguida del makuy y el g铆录icoy. Se observaron diferencias en la altura (p=0.00001) y el rendimiento (p=0.00001) de las variedades de las plantas. La biomasa de tilapia por tanque fue _ = 730 脗卤 75.2 g. En tal sentido, es posible cultivar plantas aut贸ctonas de Guatemala en un sistema acuap贸nico
