ABSTRACT:Fusarium Head Blight (FHB) represents one of the major constraints for barley production in Uruguay and significantly decreases grain yield and quality. FHB is also a major food safety concern because causal agents contaminate grains with trichothecenes and other mycotoxins. DNA sequence-based analyses and in-vitro toxin assessments were used to characterize species and trichothecene chemotype composition of FHB pathogens on barley grains in Uruguay. Fusarium graminearum was the dominant species (89.7%), and three other members of the F. graminearum species complex (FGSC) were identified
as FHB pathogens of barley in Uruguay for the first time. Other minor FHB species included F. poae,F. avenaceum, F. pseudograminearum and an unnamed species of the F. incarnatum-equiseti species complex (FIESC). Most isolates (89.7%) had the 15-acetyldeoxynivalenol (15-ADON) trichothecene
type. Yet, results from this study expanded the known area of occurrence within Uruguay for the nivalenol (NIV) toxin type, which was observed among isolates from three species of the FGSC, F. pseudograminearum, and F. poae. Isolates with the 3-acetyldeoxynivalenol (3-ADON) or NX-2 toxin types were not observed, although a previously published multilocus genotyping assay was updated to identify NX-2 strains. Analyses of population structure and comparisons with FHB isolates from wheat in Uruguay indicated that F. graminearum constitutes a single genetic population with no evidence of population differentiation related to the sampled hosts. Inter and intraspecific differences were observed in aggressiveness toward four barley genotypes with different levels of resistance to FHB, and in general nivalenol producers were the least aggressive isolates. Sensitivity to metconazole was approximately
10 times higher than the one detected for tebuconazole. This is the first report regarding tebuconazole
and metconazole sensitivity for Fusarium species causing FHB in barley in Uruguay and establishes
an important starting point for monitoring temporal or spatial changes in FGSC sensitivity, which is
critical to define FHB management practices.

ABSTRACT:
This study aimed to determine control measures for gastrointestinal nematodes in goats in the northeastern semiarid after analyzing the dynamics of gastrointestinal helminths during the drought, the evolution of the parasitic load after the first rains and the differences in susceptibility between goats of different categories and ages. Five farms were studied from March 2013 to January 2015. Feces were collected from all goats every month, for fecal egg counts (FECs). No treatment was required on any farm during the dry period. In 2013, with annual rainfall of 265-533 mm, treatments were not necessary during the rainy season. However, in 2014, with rainfall of 604-778 mm, treatments were necessary 60-90 days, after the first rains. On three farms, gastrointestinal nematodes showed multiple anthelmintic resistance. The FECs from lactating goats were significantly higher than from dry and young goats. In conclusion, in the Brazilian semi-arid region (Caatinga biome), it is generally unnecessary to treat grazing goats during the dry season. In the rainy season, the parasite load increases 2-3 months after the first rains. In both, the dry and the rainy season, farmers should monitor their herds by means of FEC or another criterion (anemia or submandibular edema), to determine the need to treat
RESUMO:Este trabalho objetivou determinar medidas de controle de nematódeos gastrintestinais de caprinos no semiárido nordestino após análise da dinâmica das infecções helmínticas durante a seca, a evolução da carga parasitária após as primeiras chuvas e as diferenças de susceptibilidade entre caprinos de distintas categorias e idades. Em cinco propriedades, de março de 2013 a janeiro de 2015, foram coletadas, mensalmente, fezes de todos os caprinos para contagem de ovos. Em nenhuma propriedade foi necessário vermifugar durante os períodos de seca. Em 2013, com precipitações de 265-533 mm anuais, não foi necessário vermifugar durante o período de chuva. No entanto, em 2014, com precipitações de 604-778 mm, foi necessário vermifugar 60-90 dias após as primeiras chuvas em três propriedades. Nessas três propriedades foi encontrada multirresistência aos anti-helmínticos. Foi constatado que o OPG das cabras lactantes foi significativamente maior do que o OPG das cabras secas e dos cabritos. Em conclusão, na região semiárida, geralmente, não é necessário o tratamento das cabras pastejando na caatinga durante a estação seca. Na estação chuvosa, a carga parasitária aumenta 2-3 meses após as primeiras chuvas. Tanto na seca quanto nas chuvas, o produtor deve monitorar o rebanho mediante OPG ou por outros critérios (anemia, edema submandibular) para determinar a necessidade de vermifugação. MenosABSTRACT:
