Soroprevalência da infecção por Chlamydophila abortus em pequenos ruminantes explorados na microrregião do Alto Médio Gurguéia, no estado do Piauí, Brasil.
[Chlamydophila abortus infection seroprevalence in small ruminants exploited in the Upper Middle Gurguéia Microregion, State of Piaui, Brazil]. Abstract: Aiming estimate the Chlamydophila abortus seroprevalence in small ruminants at upper middle Gurguéia microregion, 352 sheep and 298 goats serum samples were collected. Complement Fixation test was performed for Chlamydophila sp. diagnosis (OIE, 2000). The reaction was conducted in microplates using test serum dilutions of 1:16 to 1:512. The prevalence in small ruminants was 12.61% (82/650). Therefore, the infectious agent Chlamydophila abortus is present in sheep and goat flocks in microregion of the High Middle Gurguéia in the state of Piauí.Trabalho apresentado nos Anais do VII Congresso Norte Nordeste de Reprodução Anima (CONERA), Mossoró, maio, 2014
Soroprevalência da infecção por Chlamydophila abortus em pequenos ruminantes explorados na Microrregião HOmogênea de Teresina, Piauí, Brasil.
[Seroprevalence of Chlamydophila abortus infection in small ruminants exploited the Teresina homogeneous microregion, Piaui, Brazil]. Abstract: Aimed to conduct epidemiological survey of Chlamydophila abortus in productive and reproductive losses in sheep and goat flocks in homogeneous microregion of Teresina, Piauí, Brazil. 450 samples, 150 sheep and 300 goats were examined. Blood serum samples was stored at -20 ° C and 10 samples from each farm were randomly selected for analysis. The overall prevalence of Chlamydophila abortus in sheep and goats in homogeneous micro region of Teresina was 10.66% (48/450). The overall prevalence of infection by C. abortus in sheep flocks in the region analyzed was 11.3% (17/150) and 7% (21/300) of the overall prevalence of infection in the herd goats. The Chlamydophila abortus agent is present in sheep and goat flocks in homogeneous micro region of Teresina recording the first occurrence of this infection in goats and sheep exploited in the state of Piaui, Brazil.Trabalho apresentado nos Anais do VII Congresso Norte Nordeste de Reprodução Animal (CONERA), Mossoró, maio, 2014
Soroprevalência da infecção por Brucella ovis em ovinos explorados na microrregião homogênea de Teresina, Piauí, Brasil.
[Brucella ovis infection seroprevalence in sheep exploited the homogeneous micro Teresina, Piaui, Brazil]. Abstract: Considering the importance of this disease and the lack of data on the state of Piauí, the aim of this study was to determine the sero-epidemiological situation of Brucella ovis infection in sheep from Teresina homogeneous microregion, Piauí. The study included a sampling universe of 282 sheep distributed in 24 herds, and the samples were collected by venipuncture of the jugular vein. Serology for detection of anti-B. ovis antibodies was performed by the method of agarose gel immunodiffusion (AGID). Of the 282 samples tested, there was 5.67% (16/282) positive to B. ovis infection by immunodiffusion in agarose gel test. Brucella ovis is present in sheep flocks in Teresina homogeneous microregion, necessitating thus the implementation of control measures to prevent the spread of this disease.Trabalho apresentado nos Anais do VII Congresso Norte Nordeste de Reprodução Anima (CONERA), Mossoró, maio, 2014

Paternity testing and behavioral ecology: a case study of jaguars (Panthera onca) in Emas National Park, Central Brazil.
We used microsatellite loci to test the paternity of two male jaguars involved in an infanticide event recorded during a long-term monitoring program of this species. Seven microsatellite primers originally developed for domestic cats and previously selected for Panthera oncawere used. In order to deal with uncertainty in the mother?s genotypes for some of the loci, 10000 values of Wwere derived by simulation procedures. The male that killed the two cubs was assigned as the true sire. Although the reasons for this behavior remain obscure, it shows, in principle, a low recognition of paternity and kinship in the species. Since the two cubs were not very young, one possibility is that the adult male did not recognize the cubs and killed them for simple territorial reasons. Thus, ecological stress in this local population becomes a very plausible explanation for this infanticide, without further sociobiological implications
Forage Cactus in Different Cropping Systems in the Semi-Arid Region of Brazil
Forage cactus is a Cactaceae grown in the Semiarid region of Brazil and other regions of the world, representing vital forage support. Using legumes in consortium with forage cactus can be an alternative in the region to increase the supply of nitrogen (N) in the soil and improve the quality of the animal diet. Thus, this study aimed to evaluate the yield of the different production systems with ‘Míuda’ Cactus (Nopalea cochenillifera Salm Dyck) and Mexican Elephant Ear [Opuntia Sricta (Haw.) Haw] in consortium with the ‘Cunhã’ legumes [Clitoria ternatea (L.)] and ‘Jureminha’ [Demanthus pernambucanus (L.) Thellung]. The experiment was carried out at the experimental farm of the Federal Rural University of Pernambuco (UFRPE), located in the municipality of Garanhuns-PE. A randomized block design with four replications was used. The experimental treatments were: T1 - Forage Cactus – Miúda + D. pernambucanus; T2 - Forage Cactus Miúda + C. ternatea; T3 - Forage cactus – Mexican Elephant Ear + D. pernambucanus; T4 - Forage cactus – Mexican Elephant Ear + C. ternatea; T5 - Forage Cactus – Miúda; T6 - Forage cactus – Mexican Elephant Ear; T7 - C. ternatea; and T8 - D. pernambucanus. The forage cactus was harvested after one year of cultivation, keeping the mother cladode, while the legumes were harvested every three months with a cutting height of 20 cm. Means were compared by Tukey\u27s test at the 5% probability level. The width of the forage cactus showed different behavior in the arrangements, with the smallest width in the monoculture of forage cactus – Mexican Elephant Ear, which differed from the intercropping with D. pernambucanus. However, there were no differences in the monoculture and intercropping systems of Forage Cactus – Miúda. The Forage Cactus – Miúda showed the highest number of cladodes in all orders and greater thickness of the mother cladode in monoculture and in the intercropping with D. pernambucanus. Furthermore, the adoption of the system intercropped with legumes significantly affected the dry matter production of Forage Cactus and legume (P \u3c 0.05), with lower yields for the Forage Cactus – Miúda system in intercropping with C.ternatea. Altogether, it is concluded that the adoption of the intercropped system of cactus and legumes decreased the width of the Opuntia stricta when in consortium with D. pernambucanus. Likewise, it reduced the production of cactus and legume dry matter in the Forage Cactus – Miúda system, in consortium with C. ternatea

Hybrid quantum circuit with a superconducting qubit coupled to a spin ensemble
We report the experimental realization of a hybrid quantum circuit combining
a superconducting qubit and an ensemble of electronic spins. The qubit, of the
transmon type, is coherently coupled to the spin ensemble consisting of
nitrogen-vacancy (NV) centers in a diamond crystal via a frequency-tunable
superconducting resonator acting as a quantum bus. Using this circuit, we
prepare arbitrary superpositions of the qubit states that we store into
collective excitations of the spin ensemble and retrieve back later on into the
qubit. These results constitute a first proof of concept of spin-ensemble based
quantum memory for superconducting qubits.Comment: 13 pages, 4 figures, plus supplementary informatio
