Abstract An improved visible spectrophotometric method has been developed for cyclopiazonic acid in poultry feed and corn. The method Is based on the reaction of cyclopiazonic acid with Ehrlich reagent and detection at 580 nm. Reaction conditions were optimized with respect to reaction and measurement times and acid and Ehrlich reagent concentrations. Calibration curves were linear from 1 to 20 μg cyclopiazonic acid in 3 mL Ehrlich reagent, with a lower detection limit of 0.08 mg/kg for 50 g samples of poultry feed and corn. Recoveries from 50 g samples of poultry feed spiked with cyclopiazoni

trans-2,3-Dimethoxy-3-(phenylamino)flavanones (2), a new type of flavanone derivatives, are synthesized from flavanones or 2'-hydroxychalcones in two steps, the first one being a condensation with nitrosobenzenes (Ehrlich-Sachs reaction) and the second an oxidation with (diacetoxyiodo)benzene in methanol. Nitrone formation, an important side reaction of the Ehrlich-Sachs reaction, has also been exploited to synthesize 2 simply by use of an excess of nitrosobenzene in aqueous methanol. Syntheses of several analogues of 2 are also reported.Key words: trans-2,3-dimethoxy-3-(phenylamino)flavanones

Aim: To investigate anticancer and immunologic effects of chicken embryonic proteins (CEP) in mice bearing Ehrlich solid carcinoma. Materials and Methods: The study was carried out on male Balb/c mice bearing Ehrlich solid carcinoma. The immunizations were performed after the tumor transplantation. The immune status was assessed on days 7, 14, 21 and 28 after the tumor challenge. Cytotoxic activity (CAT) of macrophages (Mph), natural killer cells (NK), cytotoxic T-lymphocytes (CTL) and blood serum, as well as the influence of the blood serum on immune cells activity was checked in MTT-assay; M

Aspergillus fuscicans, a new species within Aspergillus section Usti from Argentinean semi-arid soil is introduced. Molecular, morphological and physiological studies were conducted, based on sequence analysis of partial β-tubulin and calmodulin sequence data. Aspergillus fuscicans formed a distinct, well-defined clade related to A. calidoustus and A. pseudodeflectus. In addition, A. fuscicans was able to grow and sporulate at 37 ºC, and had a negative Ehrlich reaction. Morphological and physiological features could be used to differentiate the new species from its phylogenetically related tax

ENGLISH ABSTRACT: Alcoholic fermentation, and especially wine fermentation, is one of the most ancient microbiological processes utilized by man. Yeast of the species Saccharomyces cerevisiae are usually responsible for most of the fermentative activity, and many data sets clearly demonstrate the important impact of this species on the quality and character of the final product. However, many aspects of the genetic and metabolic processes that take place during alcoholic fermentation remain p

A erliquiose monocitotrópica canina é caracterizada como uma infecção persistente, podendo evoluir para doença fatal. Mecanismos imunopatogênicos estão implicados no desenvolvimento da doença, porém não é completamente compreendido o papel da resposta imune celular nas infecções causadas por Ehrlichia canis transmitida pelo carrapato Rhipicephalus sanguineus. A infecção do vetor ocorre somente durante o repasto em cães riquetsêmicos, porém não é reconhecido o nível de riquetsemia infectante durante o curso da infecção nos cães.

In impoverished and resource limited communities such as townships, and welfare organizations, areas such as living and sleeping spaces are sometimes shared with animals, and occasionally humans. Dogs play an integral role in our lives and have become part of the family. Therefore, it is probable that ectoparasites, such as ticks, that feed on dogs also feed on other vertebrates, thereby, transmitting pathogens. The primary aim of this study was to screen for the presence of tick-borne pathogens in dogs from welfare organisations and townships in Cape Town, with special focus on Ehrlichia and

Human infections with Ehrlichia species have been found worldwide. It appears that at least six different species infect humans, and clinical and epidemiological data are highly suggestive of sole transmission by ticks. The clinical illness is a nonspecific febrile syndrome, often accompanied by cytopenias, abnormal liver enzymes, and “aseptic” meningitis. When diagnosis is delayed, it is occasionally fatal. Currently, the polymerase chain reaction (PCR) technique is the most rapid technique to confirm the clinical diagnosis. The infection is responsive to tetracyclines and chloramphenicol. In
