Mortality supposedly due to intoxication by pyrrolizidine alkaloids from heliotropium indicum in a horse population in costa rica: a case report
(Taylor and Francis Group, 2011-11-01)This article describes a case of massive mortality among horses which was probably due to intoxication by pyrrolizidine alkaloids from Heliotropium indicum. Over 4 years more than 75% of a population of about 110 horses ... -
New insights into Neutrophil Extracellular Trap (NETs) formation from porcine neutrophils in response to bacterial infections
(MDPI, 2022-08-11)Actinobacillus pleuropneumoniae (A.pp, Gram negative) and Streptococcus (S.) suis (Gram positive) can cause severe diseases in pigs. During infection, neutrophils infiltrate to counteract these pathogens with phagocytosis ... -
Trypanosoma cruzi Infection in Rhodnius pallescens (Heteroptera: Reduviidae) Infesting Coyol Palms in the Dry Arch of Panamá
(Oxford University Press on behalf of Entomological Society of America, 2018-02-07)Ecoepidemiological scenarios for Trypanosoma cruzi Chagas transmission are partially shaped by kissing bug vector ecology. The presence of Attalea butyracea Kunth, the ‘royal palm’, is a major risk factor for Chagas ... -
