Online identification of Mysida through NeMys

Identification of specimens is a task that every biologist is confronted with. The process of identification in many cases delivers many problems due to unavailability of keys, difficult specialised keys or old keys.Within NeMys (http://intramar.ugent.be/nemys) recently a new identification module has been added. Based upon morphological data derived from published literature, polytomous digital identification keys are made. This kind of keys has the advantage that users are not forced to follow a predefined pathway (as in dichotomous keys), users can choose their best suitable characteristics to work with and the keys can be easily updated with new insights through a fully online key-generation system.By using internet technologies, the identification keys are at any time anywhere available for use. As the data used in the keys is derived from the database system NeMys, it is also possible to check the identification process at any level, with literature sources, images, distribution patterns, … on the website of NeMys.This kind of technology opens new possibilities for biologists to share their taxonomic knowledge with a broader audience without being forced to go through the difficult process of creating dichotomous paper-based keys

Prevalence of respiratory pathogens in nasal swabs from horses with acute respiratory disease in Belgium

Contagious respiratory infections are an important cause of respiratory disease in horses, resulting in impaired pulmonary function, poor performance and sometimes severe illness. Although bacterial infections are often suspected to be involved, viruses are frequently overlooked and are an underestimated cause of respiratory disease outbreaks in horses. In this study, nasal swabs of 103 horses with acute symptoms of respiratory disease were analyzed for the presence of 13 different respiratory pathogens. Gamma herpesviruses were the most commonly detected, with 60% of the samples being positive, followed by streptococcus equi subsp. zooepidemicus infection (30%). Rhinovirus B, streptococcus equi subsp. equi, adenovirus 1 and EHV-4 were more rarely detected. Further research is necessary to correctly interpret the importance of gamma herpesviruses in horses, for example by screening a healthy control population. National surveillance of respiratory viruses in horses by PCR analysis on nasal swabs might be a useful, early warning system for viral epidemics
