In the few cases of acute childhood diarrhea that require antimicrobial therapy, the correct choice of the drug depends on detailed previous knowledge of local strains. In order to establish such parameters in our city, we reviewed the results of all 260 positive stool cultures of children between 0 and 15 years of age during two years at a pediatric tertiary care facility in Salvador, Brazil. Bacterial strains had been presumptively identified by culturing in selective media and by biochemical testing, and their antimicrobial susceptibility patterns were automatically detected by the MicroScan Walkaway System. Data about patients' sex and age, monthly distribution of the cases, pathogens isolated and their antimicrobial resistance patterns were recorded.... |

Phytophthora capsici, Fusarium sp. y Rhizoctonia solani son los principales agentes causales de la marchitez del chile que disminuye el rendimiento del cultivo, lo cual ha originado la sustitución de cultivos y abandono de tierras. Con el fin de coadyuvar al manejo de esta enfermedad en el presente trabajo se evaluaron 51 accesiones de chile (árbol, copi y soledad) para buscar fuentes de resistencia; se probó metalaxyl, fosetil aluminio y tiabendazol para evaluar la sensibilidad de un aislamiento de P. capsici y se evaluó el Serrano Criollo de Morelos 334 (SCM334) resistente a P. capsici como portainjerto de las variedades susceptibles para el manejo de la marchitez del chile. El análisis de los resultados muestra que P. capsici tiene una sensibilidad... |

Commercial sugar beet hybrids were evaluated for resistance to Beet severe curly top virus in a furrow-irrigated sugar beet field near Ontario, OR where curly top had been a problem in previous years. The field trial relied on natural infection and was planted on 6 Apr. Plots were planted to a density of 285,120 seeds/A, and thinned to 40,731 plants/A. Plots were four rows wide (22 in. between rows) and 23 ft long. The experimental design was a randomized complete block with eight replications. The crop was managed according to standard cultural practices. The weather during the growing season was normal except for above average temperatures in Mar and Aug and above average precipitation in Apr and May. Disease pressure was uniform and moderately... |

Twenty-five experimental sugarbeet hybrids submitted to the official variety trials were evaluated for resistance to Beet curly top virus (BCTV). Hybrids were planted in a commercial sprinkler-irrigated sugarbeet field and exposed to a natural epiphytotic of BCTV. Experimental units were arranged in a randomized complete block design with seven replications. Plots were evaluated for BCTV based on a Disease Index (DI) scale of 0 to 9 (no symptoms to dead) on Sept 14, 2004 by three raters. The moderately severe epiphytotic resulted in uniform disease pressure and significant differences between hybrids for DI, root yield, sugar content, and estimated recoverable sugar. Our disease ratings were positively correlated with (r = 0.632, P < 0.0001)... |

Preventing sucrose losses in storage is important to the economic viability of the sugar beet industry. In an effort to establish additional measures for reducing sucrose losses in storage, ten fungicide and/or biological treatments were evaluated on sugar beet roots in a commercial sugar beet storage building for their ability to limit fungal growth on roots harvested 2 Oct. Six of the treatments were applied as a direct spray to roots, but two treatments were applied as a cold fog and two others were applied as a thermal fog. The treated eight-beet root samples were arranged in a randomized complete block design with 6 replications on top of the commercial sugar beet pile inside a storage building. Roots were evaluated for fungal growth, root rot,... |

We analyzed the first 96 patients tested for HIV resistance to antiretroviral therapy in three Brazilian states. The HIV-1 reverse transcriptase (RT) and protease (PR) were sequenced by using the ABI ViroSeq system. The drugs previously used for each patient were recorded and correlated with the mutations found in the samples. Viral load (VL) and CD4 count were also recorded. Only one patient had the wild type sequence. The most prevalent mutations were: 184V (59%), 41L (47.9%), 63P (53%), 215Y (50%), 36I (46%), 10I (35%), 67N (42%), 77I (37%), 90M (36%) and 210W (33%). A positive correlation between the number of previously used ARVs and the number of mutations was observed (p<0.05). Associations between mutations and ARV drugs were identified at... |

ABSTRACT Bacterial wilt limits tomato production and resistant rootstocks could be important for the integrated management of the disease. Since there is an interaction between local bacterial strains and tomato genotype, this study aimed to evaluate 14 tomato rootstocks to bacterial wilt in the Mata mesoregion of Pernambuco state, Brazil. The rootstocks reaction to two sequevars of Ralstonia solanacearum and two of R. pseudosolanacearum was evaluated in four experiments carried out in the greenhouse using the completely randomized experimental design, with four replications composed of four plants each. Seven genotypes were selected to evaluate the reaction to bacterial wilt as rootstocks grafting in tomato plants ‘Tomini F1’ in a production area with... |
