| This paper reports partial results obtained on the variability of Colletotrichum graminicola developed in response to the host diversity generated by three-line combination of sorghum (Sorghum bicolor) genotypes. Nine sorghum lines were used in this study: CMSXS210B, CMSXS112B, CMSXS215B, CMSXS221B, CMSXS169R, CMSXS180R, CMSXS182R, CMSXS227R, and CMSXS116R. A total of 39 treatments on mixtures and pure stands of the component lines were evaluated in the field for the development of anthracnose, as a natural epidemic. Samples of the single spore isolates of the pathogen of each treatment indicated a reduction in the phenotypic diversity and an increase in the frequency of more complex races in genotype mixtures in relation to the pure stands of each genotype. |

| The main objective of this work was to identify sources of resistance in sorghum (Sorghum bicolor) to Peronosclerospora sorghi, the causal agent of downy mildew, through the evaluation of 42 sorghum genotypes under natural infection in the field. Genotypes were planted in single row plots between two rows of the susceptible line SC283, planted 30 days before, to act as spreader rows, in two separate nurseries. The experimental design was a completely randomized block design with three replications. Sorghum genotypes CMSXS156, CMSXS157, CMSXS243, TxARG-1, 8902, 9902054, 9910032, 9910296, Tx430, QL-3, SC170-6-17, CMSXS762 and BR304 were classified as highly resistant in both nurseries. Among these, SC170-6-17 and 9910296 showed 0% systemic infection. Results... |

| ABSTRACT The study was conducted based on the information collected on rural properties in the state of Goiás, during practical classes of Surgical Clinic in Large Animals at the Veterinary Hospital of the Escola de Veterinária e Zootecnia of the Universidade Federal de Goiás and during the implementation of outreach projects developed by the institution. An acropostite-phimosis surgical procedure in the bulls in the field was selected, lasting over 30 minutes and requiring movements, posture and strength on the part of the surgeon. Devices were proposed and developed to provide improved comfort and safety to surgeons. The first device was a stool to be used by the professional during the execution of the surgical intervention. The use enabled the surgeon... |

| We herein report tick (Acari: Ixodidae) infestation of four domestic dogs wandering inside Serra de Caldas Novas State Park, Goiás. Twenty seven ticks were collected from these hosts along nine days in November 2008. Ticks were identified as adults of Amblyomma cajennense, Amblyomma ovale, Amblyomma tigrinum and Rhipicephalus sanguineus as well as Amblyomma spp. nymphs. One of the dogs displayed facial myoclonus, a symptom of canine distemper. Such disease is a serious viral and contagious disease of dogs and also of several wild animals. Overall tick species found on dogs clearly showed the transit of these hosts between the natural areas of the park and anthropic areas, urban or rural. Such situation illustrates the potential of dogs to transmit... |

| Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correctly identifying the fungus Fusarium guttiforme, agent of the pineapple fusariosis, have led to the search for new methodologies, and for this we developed a new reliable molecular method to detect it. For diagnostic purposes, real-time PCR of elongation factor gene 1-α (ef1) was used to rapidly, specifically and sensitively diagnose F. guttiforme. A pathogenicity test was conducted with slips of the... |
