Abstract
La muerte de las colonias es un mecanismo multifactorial dentro del cual participan los patógenos de las abejas, como Nosema ceranae. Este microsporidio ha demostrado su acción patógena mediante la disminución de la productividad y viabilidad de las colonias a las que infecta, llegando incluso a producir su muerte.En el presente trabajo se analizan distintas estrategias para el control de la nosemosis. La primera de ellas se basa en el desarrollo de medidas profilácticas para lo cual fue necesaria la puesta apunto de una metodología que evalúa la capacidad esporicida de varios productos para su uso en la limpieza del material apícola. Mediante la metodología desarrollada se evaluó positivamente la eficacia de varios productos de uso doméstico como el amoniaco, lejía y ácido acético para la desinfección del material apícola, eliminando las esporas de N. ceranae. Otros productos comerciales como el Mycoplasma OFFTM también surten el mismo efecto. Las técnicas profilácticas deben formar parte del control integral de enfermedades ya que evitan la entrada y difusión del patógeno de manera antropogénica, disminuyendo el riesgo de infección en individuos sanos...
The death of the honey bee colonies is a multifactorial mechanism in which pathogens, such as N. ceranae, are participating. This microsporidium has demonstrated to have pathogenic action because it reduces the productivity and viability of the colonies it infects, even killing them. In this work, different strategies to control nosemosis are analyzed. The first of all, prophylactic measures were evaluated to determine the sporicidal capacity of several products to clean beekeeping material. To do this, a new methodology was previously developed. This methodology allowed us to determine that several common products such as ammonia, bleach and acetic acid were able to disinfect beekeeping material, eliminating N. ceranae spores. Other commercial products such as Mycoplasma OFFTM has a similar effect. Prophylactic techniques should be part of disease control system since it avoids the entry and diffusion of the pathogens by anthropogenic action, reducing the risk of infection in healthy colonies...
