In experimental fields of the Embrapa Gado de Corte, in Campo Grande, Mato Grosso do Sul State, midwestern Brazil, plants of Brachiaria humidicola cv. Humidicola with leaf lesions symptoms caused by Uromyces setariae-italicae were found. This is the first report of the disease in Mato Grosso do Sul.

Luteoma is a rare neoplasm occurring through the luteinization of granulosa and follicular theca cells. It is related to alterations in the levels of estrogen, progesterone, testosterone and chorionic gonadotrophin, resulting in behavioral changes of nymphomania and masculinization. It is reported a case of luteoma diagnosed by histopathological examination in one of the ovaries of a cow slaughtered in a slaughterhouse. In live animals the tumor can be diagnosed through ultrasonography and transretal palpation, emphasizing the use of these measures in parallel to the gestational diagnosis, in the promotion of gynecological screenings. Report the occurrence of luteoma highlights the importance of deeper gynecological examinations for its detection and treatment.

The egg is a food of great acceptability for human consumption because it is rich in nutrients in its composition and has low market value, thus becoming a common food in the table of the Brazilian population. The article analyzes works published in the last five years, with emphasis on microbiological contamination by Salmonella spp. in eggs, through a systematic bibliographic review of articles in electronic databases such as Scielo, Science Direct and Google Scholar. The objective of this study was to relate the studies on the quality and contamination of eggs in published articles using as criteria of selection the year of publication, the database found, the information contained, besides selecting seven articles for discussion. From the data obtained it was observed that the contamination by Salmonella spp. occurs mainly through poor storage and inadequate temperatures. It is necessary the quality control in the production of eggs, improvements in hygienic-sanitary conditions, temperature and the form of storage to reverse the data found.

In the global ornamental plant industry, gerbera is among the top 10 cut flowers. This specie, commercially, micropropagation is more important than seminiferous propagation and natural vegetative propagation. Oobjective of this study was to evaluate the growth of gerbera genotypes micropropagated plants in the acclimatization. The experiment was installed in the acclimatization of micropropagation a randomized block design with seven treatments (gerbera genotypes) and 10 blocks (repetitions). Each parcel consisted of eight seedlings.

The objective of this work was to evaluate the microbiological quality of the refrigerated raw milk commercialized informally in the city of Imperatriz – Maranhão. Nine samples of raw milk were collected at several sales points and the samples were submitted to the most probable number (NMP) of Coliforms at 35 °C and Coliforms at 45 °C, detection of coliforms and intestinal pathogens. The microbiological results of the analyzed samples did not present in a quality standard. As the milk purchased was through informal commerce, there is no way to affirm the causes of this precarious condition of milk marketed in the city of Imperatriz – Maranhão.

The effect of genotype and slaughter weight on yield, absolute weight and growth of internal organs, fat depots and non-carcass components of lambs were evaluated. 34 male lambs (17 crossbred Lacaune x Santa Ines and 17 purebred Santa Ines) were arranged in a completely randomized design (factorial 2x4) - 2 genotypes and 4 slaughter weights (15; 30; 45 and 60 kg of LW). Proportion of internal organs decreases with slaughter weights. Proportion of fat deposits increases with slaughter weights. The crossbreed lambs obtained greater proportion of liver and guts, while pure animals had higher proportions of omental, pelvic and inguinal fat. Internal organs grew precociously compared to the body. Fat deposits shows strong positive allometry. There was no strong genotype effect on allometric growth.

The objective of this study was to evaluate the performance of alternative substrates from the grain industries of Paragominas-Pará, for the production of cabbage seedlings. The experimental design was completely randomized, with three treatments (soybean residue, rice straw, commercial substrate) with five replications. The following morphological characteristics were determined: height of the seedlings, diameter of the lap, number of leaves per plant, fresh shoot weight, dry shoot mass, fresh root mass, dry mass of the roots. Therefore, in this study it was concluded that the soybean residue was the substrate that most stood out, indicating the potential of this material as a substrate for the crop.

The cultivation of chilli pepper ( Capsicum chinense Jacq.) is subject to the attack of several diseases, like anthracnose that mainly affects the fruits preventing the commercialization. The objective of this work was to perform the morphocultural, molecular and pathogenic characterization of Colletotrichum spp. from chilli pepper, collected in producing municipalities of the State of Amazonas. High variability was observed in morphological characteristics of color and topography of colonies, mycelial growth index, and morphometry of conidia and apressoria. Significant differences were observed in the severity, mean diameter of lesions and incidence when the isolates were inoculated in four species of Capsicum . Ap-PCR genotyping evidenced high genetic diversity among isolates from the same source, and possibly, the existence of different species or complexes of species associated with anthracnose in chilli pepper in the State of Amazonas.

The usual potato production system restricts cultivation in the same area for consecutive years. In order to overcome this limitation, a deep tillage system was developed with the incorporation of organic material. The objective of this work was to evaluate the microbial activity of the soil submitted to different soil management, with and without the incorporation of Panicum maximum ; Brachiaria brizantha and maize for the cultivation of potatoes. The incorporation of P. maximum was able to maintain the microbiological activity of the soil stable during the cycle. The deep preparation presented higher potato productivity compared to the usual tillage.

The composition of the arbuscular mycorrhizal fungi (AMF) community was evaluated after the native vegetation was replaced by pasture. The systems: Andropogon gayanus , Brachiaria brizantha , Panicum Maximum and Cynodon dactylon and an agrosilvipastoril system (AFS) were studied; and a fragment of native forest. Soil samples were collected at depth of 20 cm. Eight families, 11 genera and 19 species of AMF were characterized. Glomeromycota species predominated in most pasture systems for both seasons, indicating the adaptation of these fungi.

Several researches confirm the existence of a high relationship between the magnetic field and many biological processes at cellular scale. There are several methodologies of micro-propagation, however, the obtained results in the acclimatization phase, are not yet desired. The objective of the present study was to characterize the quality of the stomata of vitroplants of pineapple during the acclimatization phase and to evaluate the influence of irrigation with magnetically treated water (MTW) six months after the acclimatization. The magnetizer employed had an induction level of 50-70 mT. When evaluating the results, it was observed that the stomata conserve its anatomy while increasing the stomata and stomatal opening area values, with 64x10 3 stomata mm -2 in the treated pineapple vitroplants compared to the untreated ones, that presented 61.6x10 3 stomata mm -2 ; as well as, also presented 3.06 µm 2 of stomatal opening area, in relation to the untreated ones that presented 2 µm 2 . These results show the ease of treatment and the potential of MTW technology as an effective management via in the acclimatization areas of plants produced “ in vitro” .

In experimental fields of the Embrapa Gado de Corte, in Campo Grande, Mato Grosso do Sul State, midwestern Brazil, plants of Stylosanthes guianensis with symptoms of rust caused by Puccinia stylosanthis were found. This is the first report of the disease in Mato Grosso do Sul.
