Exploratory serosurvey for antibodies to avian pathogens in backyard chickens from a satellite community of Jalapa City, Guatemala

An 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®) 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

The relationship of child rearing and the level of anxiety of first year medical students in De La Salle Health Sciences Institute (DLSHSI), school year 2012-2013

A cross-sectional study design was implemented for this research. Using non-probability purposive sampling method, 306 first year medical students aged 18 to 30 were surveyed regarding their parent\u27s parenting style implemented on them during ages 6-12 years old and the student\u27s level of anxiety by using a modified parenting style questionnaire and Zung Self Anxiety Rating Scale respectively. Chi-square test was used to analyze the data. The results showed the levels of anxiety of first year medical students were not affected by parenting styles, caregiver and parental status
