A unique substitution at position 333 on the glycoprotein of rabies virus street strains isolated from non-hematophagous bats in Brazil

The amino acid R or K at position 333 on the glycoprotein of the rabies virus is considered necessary for virulence in adult mice. Although some exceptions exist, substitution at this position causes expression of a phenotype that is either less pathogenic or non-virulent. To date, such substitutions have only been found in fixed strains of rabies virus. In this study, the authors found 333H, 333N, and 333Q substitutions at this position in rabies virus street strains isolated from non-hematophagous bats in Brazil. These strains showed pathogenicity and lethality on passage using adult mice with the intracerebral route and were confirmed rabies-positive by immunofluorescent assay. This suggests that these strains maintain virulence. Our findings indicate that rabies virus street strains with these substitutions exist in the field and may result in infection cycles.

Serrated route to colorectal cancer: back street or super highway?

Morphological and molecular studies are beginning to distinguish separate evolutionary pathways for colorectal cancer, The serrated pathway encompassing hyperplastic aberrant crypt foci, hyperplastic polyps. mixed polyps, and serrated adenoma is increasingly being linked with genetic alterations, including DNA methylation, DNA microsatellite instability, Ii-ras mutation, and loss of chromosome Ip, The importance of the serrated pathway has been underestimated in terms of its frequency and potential for rapid progression, Copyright (C) 2001 John Wiley & Sons, Ltd.

Microscopic analysis of "prato", "mussarela" and "mineiro" cheese sold in street markets of the City of S. Paulo, Southeastern Brazil

INTRODUCTION: Cheese should be produced from ingredients of good quality and processed under hygienic conditions. Further, cheese should be transported, stored and sold in an appropriate manner in order to avoid, among other things, the incorporation of extraneous materials (filth) of biological origin or otherwise, in contravention of the relevant food legislation. The aim of the study was to evaluate the hygienic conditions of "prato", "mussarela", and "mineiro" cheeses sold at the street food markets in the city of S. Paulo, Brazil. MATERIALS AND METHOD: Forty-seven samples of each of the three types of cheese were collected during the period from March, 1993 to February, 1994. The Latin square was used as a statistical model for sampling and random selection of the street markets from which to collect the cheese samples. The samples were analysed for the presence of extraneous matters outside for which purpose the samples were washed and filtered and inside, for which the methodology of enzymathic digestion of the sample with pancreatine, followed by filtering,was used. RESULTS AND CONCLUSION: Of the 141 samples analysed, 75.9% exhibited at least one sort of extraneous matters. For the "prato" and "mussarela" cheeses, the high number of contaminated samples was due mainly to extraneous matters present inside the cheese, whereas in the "mineiro" cheese, besides the internal filth, 100% of the samples had external filth.

CALLIPHORIDAE (DIPTERA) IN MANAUS: IV. BACTERIA ISOLATED FROM BLOWFLIES COLLECTED IN STREET MARKETS

Staphylococcus aureus, Escherichia coli, Proteussp., Providenciasp., Citrobactersp. and Klebsiellasp. were isolated from calliphorid flies collected in eight street markets in the city of Manaus, Amazonas State, Brazil. The presence of £. coliin the samples suggests that faecal contamination is occurring and that these flies are potential vehicles of enteropathogenic bacteria to exposed foods.
