Dry root disease of yam (Dioscorea spp.), caused by Scutellonema bradys, Pratylenchus coffeae and brachyurus, isprominent among the plant disease problems of yam in Brazil. In order to evaluate the association of these nematode species withweeds, field sampling was performed during 2016 and 2017 in yam-growing areas with a history of the disease within the majorcounties in the state of Alagoas, Brazil. The frequency of occurrence of both weeds and nematodes was determined, in addition tothe estimated population of nematodes in roots. Forty-three weed species were found, of which 23 were infected with at least one ofthe causal agents of the dry rot disease, Pratylenchus spp. being the most prevalent in the fields. Ageratum conyzoides, Commelina benghalensisandEmilia coccinea (in Zona da Mata) and C. benghalensis (Agreste region) were especially important due to theirhigh frequency of occurrence and also for supporting populations of bradysan Pratylenchus spp. Cyperus flavus, coccinea and permacoce verticillataare now recorded as new weed species associated with. bradys. |

Valuable female cattle are continuously subject to follicular puncture (ovum pick-up - OPU). This technique is commonly used for in-vitro embryo production, but may result in ovarian lesion. Mesenchymal stem cells (MSC) ameliorate the function of injured tissues, but their use to treat ovarian lesions in cattle has not been established. We investigated whether a local injection of MSC would reduce the negative efects of repeated OPU under acute and chronic scenarios in bovines. First, we performed four OPU sessions and injected 2.5×106 MSCs immediately after the 4th OPU procedure (n=5). The treated organs (right ovary) were compared to their saline-treated counterparts (left), and presented superior production of oocytes and embryos in the three following OPU sessions (P<0.05). Then, cows with progressive fertility loss went through three OPU sessions. Animals received MSC, saline, or MSC+FSH in both ovaries after the frst OPU. In the two following OPU sessions, the MSC and MSC +FSH - treated groups failed to present any signifcant alteration in the number of oocytes and embryos compared to saline-treated animals. Thus, MSC have benefcial efects on the fertility of OPUlesioned cows, but not in cows with cystic ovarian disease and chronic ovarian lesions. |
