Authors: H.M. Lopes, C.S. Bastos, L.S. Boiteux, J. Foresti and F.A. Suinaga
Helicoverpa armigera is the most significant pest of agriculture in Asia, Europe, Africa, and Australasia, causing damage to crops greater than US$2 billion annually and until 2013 it was not detected in Brazil. Helicoverpa zea is restricted to the American continent and is important to corn and a secondary pest of cotton and .. Read More»

Population genetic structure of three species in the genus Astrocaryum G. Mey. (Arecaceae)
Authors: N.P. Oliveira, M.S.P. Oliveira, L.C. Davide and S. Kalisz
We assessed the level and distribution of genetic diversity in three species of the economically important palm genus Astrocaryum located in Pará State, in northern Brazil. Samples were collected in three municipalities for Astrocaryum aculeatum: Belterra, Santarém, and Terra Santa; and in two municipalities for .. Read More»

A Xanthomonas citri subsp citri hypothetical protein related to virulence contains a non-functional HD domain and is implicated in flagellar motility
Authors: F.C.F. Vieira, A.M. Gon�§alves, E.F.R. Mendoza, R.M. Ferreira, M.L.M. Costa, T.S. Balbuena, H.G. Sebinelli, P. Ciancaglini, J.M. Pizauro Junior and J.A. Ferro
Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp citri (Xac), severely affects most economically important citrus varieties worldwide. A previous study showed that disruption of the ORF XAC1201 from the Xac 306 strain by transposon Tn5 decreased bacterium virulence in the Rangpur lime host (Citrus l.. Read More»

Supplementation levels of exogenous alpha-amylase in broilers diets
Authors: H.B. Oliveira, M.I.A. Silva and F.R. Mesquita
This study aimed to evaluate the supplementation levels of an exogenous alpha-amylase in broilers diets and compare two indicators in determining the diets energy. The experiment was divided into two parallel evaluations, being one of performance and the other of metabolism. In performance assay, 1,700 one-day-old Cobb-500 mal.. Read More»

Novel multiplex PCR for detection of diarrheagenic Escherichia coli strains isolated from stool and water samples
Authors: J.W. Vendruscolo, T.L. Waldrich, G.I.A. Saikawa, J.S. Pelayo, R.K.T. Kobayashi, G. Nakazato, S.P.D. Rocha
Diarrhea is considered the second most common cause of infant mortality worldwide. The disease can be caused by many different pathogens, including diarrheagenic Escherichia coli (DEC), which includes the pathotypes enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), Shiga toxin-pro..

Antimicrobial activity of essential oil and growth of Ocimum basilicum (L.) inoculated with mycorrhiza and humic substances applied to soil
Authors: F. Morelli, L. Ferarrese, C.L. Munhoz and O. Alberton
Mycorrhizal association increases the absorption of water and nutrients by plants, and thus, affects their metabolism. This study aimed at assessing the single and conjoint effects of the arbuscular mycorrhizal fungus (AMF) Claroideoglomus etunicatum and soil’s humic substances (HS) on the composition of essential oil (E..

Generic relationships among Molluginaceae inferred from a molecular phylogenetic analysis of the matK gene
Authors: M.A. Ali, J. Lee and F. Al-Hemaid
The family Molluginaceae (order Caryophyllales) is considered polyphyletic based on the photosynthetic pathway, C4 evolution, and phylogeny of the family. This inference was made based on photosynthetic, anatomical, and molecular datasets. The generic circumscription of this family has greatly been changed owing to the placeme.. Read More»

The Staphylococcus aureus is the most common isolated microorganism in ruminant animal species diagnostic with clinical or subclinical mastitis. Dairy herds with these diseases can transfer S. aureus into the milk supply, which can lead to food poisoning in humans. The objective of this study was to evaluate the profile of ant.. Read More»

Correlation of forkhead box transcription factor O1 and myosin heavy chain isoforms in porcine skeletal muscle
Authors: X.E. Shi, Z.Y. Song, Q.M. Yang, Y.G. Liu and G.S. Yang
We examined the expression of myosin heavy chain (MyHC) isoforms and forkhead box transcription factor O1 (FoxO1) in porcine soleus and extensor digitorum longus (EDL) muscles to clarify the correlation of FoxO1 and the relative abundance of transcripts of MyHC isoforms. Soleus muscle was found to be redder than EDL muscles in pigs, and immunohistochemica.. Read More»
