Objectives: Paratuberculosis (PTBC) is a chronic infectious disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP), with an important economic impact in the dairy sector. This study aimed at evaluating and comparing the performance of two molecular diagnostic tests (PCR and qPCR) for the detection of MAP shedding in feces and milk of seropositive dairy cows across time. |

Abstract: Honeybees Apis mellifera are important pollinators of wild plants and commercial crops. For more than a decade, high percentages of honeybee colony losses have been reported worldwide. Nutritional stress due to habitat depletion, infection by diferent pests and pathogens and pesticide exposure has been
proposed as the major causes. In this study we analyzed how nutritional stress afects colony strength and health. Two groups of colonies were set in a Eucalyptus grandis plantation at the beginning of the fowering period (autumn), replicating a natural scenario with a nutritionally poor food source. While both groups of colonies had access to the pollen available in this plantation, one was supplemented with a polyforal pollen patty during the entire fowering period. In the short-term, colonies under
nutritional stress (which consumed mainly E. grandis pollen) showed higher infection level with Nosema spp. and lower brood and adult bee population, compared to supplemented colonies. On the other hand, these supplemented colonies showed higher infection level with RNA viruses although infection levels were low compared to countries were viral infections have negative impacts. Nutritional stress also had long-term colony efects, because bee population did not recover in spring, as in supplemented colonies did. In conclusion, nutritional stress and Nosema spp. infection had a severe impact on colony strength with consequences in both short and long-term. |
