In Vitro Evaluation of Sodium Hypochlorite, Chlorhexidine, Propolis, and Calcium Hydroxide Effect on Lipoteichoic-Acid-Induced Proinflammatory Cytokines Production.

This study aimed to evaluate the effects of sodium hypochlorite (NaOCl), chlorhexidine (CHX), and the glycolic extract of propolis (GEP) as endodontic irrigants and of calcium hydroxide [Ca(OH)], CHX, or Ca(OH) + CHX as intracanal medications on the capacity of the lipoteichoic acid (LTA) of in macrophages' proinflammatory cytokines production. Freshly extracted 108 human single-rooted teeth were used in this study. The LTA of was standardized in double-distilled pyrogen-free water (250 µg/mL) and inoculated into the specimens subdivided into nine subgroups (n = 12).

Phytochemical Composition and Antimicrobial and Antibiofilm Effect of Hydroethanolic Extract against and .

and are opportunistic pathogens, and both are involved in different oral infections. This work aimed to analyze the phytochemical composition of hydroethanolic extract and to evaluate its antimicrobial and antibiofilm action against (ATCC 6538) and (ATCC 19606; multi-resistant clinical strains 58004, 50098, 566006, and H557). hydroethanolic extract was prepared, and the content of soluble solids, flavonoids, and phenols was quantified.

species causing cassava ( Crantz) anthracnose in different eco-zones within the Recôncavo Region of Bahia, Brazil.

A survey to investigate the occurrence of cassava anthracnose disease (CAD) and distribution of spp. in cassava plantations in different eco-zones of the Reconcavo Region in Bahia, Brazil, investigated during the rainy season of 2014. A total of 50 cassava fields distributed among 18 municipalities were visited and intensity of anthracnose evaluated.

Cleaning cassava genotypes infected with cassava frogskin disease via in vitro shoot tip culture.

This study aimed to develop a methodology for eliminating cassava frogskin disease (CFSD) from in vitro shoot tip culture by associating thermotherapy and tetracycline. Cuttings from different accessions (BGM0232, BGM0315, BGM0464, BGM584, BGM0841, and BGM1342), infected with CFSD according to visual inspection of the disease symptoms, were used for cleaning. To verify the absence of other diseases, the plants were indexed for Cassava common mosaic virus - CsCMV (by ELISA) and Cassava vein mosaic virus - CsVMV (by polymerase chain reaction, PCR), proving that the accessions were free of these viruses, except for BGM0315 and BGM0464, which were infected with CsVMV.
