25. Infecção por Piscinoodinium pillulare (Schäperclaus, 1954) Lom, 1981 (Dinoflagellida) em peixes de água doce cultivados na região Nordeste do Estado de São Paulo, Brasil: aspectos parasitológicos e patológicos
O Centro de Aqüicultura, Unesp, Jaboticabal, SP, Brasil, recebeu peixes para diagnose, os quais apresentavam aglomeração nas bordas dos viveiros e na entrada da água. Dos 194 casos diagnosticados, 53 apresentavam estruturas brancas circulares ou ovais, imóveis, medindo 162 mm de diâmetro, identificadas como o dinoflagelado Piscinoodinium pillulare. Em

26. Fauna parasitária de peixes oriundos de "pesque-pague" do município de Franca, São Paulo, Brasil. I. Protozoários
The present work studied protozoan parasites of cultivated fishes (N = 433) from two feefishing farm situated in Franca, São Paulo, Brazil, during a period of April 1997 through March 1999. Specimens of piauçú Leporinus macrocephalus Garavello & Britski, 1988 (Anostomidae), pacu Piaractus mesopotamicus Holmberg, 1887 (Characidae) carp Cyprinus carpio Linn

27. Induction of pheromone production in a moth by topical application of a pseudopeptide mimic of a pheromonotropic neuropeptide.
An amphiphilic analog of Locusta myotropin II (Lom-MT-II), Glu-Gly-Asp-Phe-Thr-Pro-Arg-Leu-amide, was synthesized by addition of 6-phenylhexanoic acid (6-Pha) linked through alanine to the amino terminus. This pseudopeptide, [6-Pha-Ala0]Lom-MT-II, was found to have pheromonotropic activity equivalent to pheromone biosynthesis activating neuropeptide when inj

28. Evaluation of three differential media for detection of Enterobacter agglomerans (Erwinia herbicola).
Dextrin-fuchsine-sulfite medium (DFS), Rimler-Shotts agar (RS), and a new lysine-ornithine-mannitol agar (LOM) were tested for detection of Enterobacter agglomerans. In human stools, LOM and DFS were most sensitive at coliform-to-E. agglomerans ratios of less than or equal to 10(2) and E. agglomerans inocula of greater than 10(2) per plate. Both LOM and DFS

29. A Salmonella typhimurium virulence protein is similar to a Yersinia enterocolitica invasion protein and a bacteriophage lambda outer membrane protein.
The phoP-phoQ-regulated pagC locus is essential for full virulence and survival within macrophages of Salmonella typhimurium. The protein product, DNA sequence, and transcript of pagC were determined. The pagC locus encodes a single 188-amino-acid membrane protein that is similar to the ail-encoded eucaryotic cell invasion protein of Yersinia enterocolitica

30. Specificity of the complement resistance and cell association phenotypes encoded by the outer membrane protein genes rck from Salmonella typhimurium and ail from Yersinia enterocolitica.
Virulence-associated phenotypes of an outer membrane protein gene family of members of the family Enterobacteriaceae were compared by means of pBR322 constructs transformed into Escherichia coli HB101.rck (Salmonella typhimurium) and ail (Yersinia enterocolitica) promote serum resistance and eukaryotic cell invasion, properties not shared by other members of

31. Structural bases of a long-stretched deletion: completing the lambda plac5 DNA primary structure.
In studying molecular mechanisms of specialised transduction, the lacI (E. coli)-Ea47 (lambda) DNA junction in transducing bacteriophage lambda plac 5 has been structurally elucidated, thus yielding the complete sequence of lambda plac 5 DNA including the lac5 substitution, a well-known segment of lambdoid vectors. The lambda plac5 DNA is shown to consist of

32. Ndrg1-Deficient Mice Exhibit a Progressive Demyelinating Disorder of Peripheral Nerves
NDRG1 is an intracellular protein that is induced under a number of stress and pathological conditions, and it is thought to be associated with cell growth and differentiation. Recently, human NDRG1 was identified as a gene responsible for hereditary motor and sensory neuropathy-Lom (classified as Charcot-Marie-Tooth disease type 4D), which is characterized

33. Sequence of Shiga Toxin 2 Phage 933W from Escherichia coli O157:H7: Shiga Toxin as a Phage Late-Gene Product†
Lysogenic bacteriophages are major vehicles for the transfer of genetic information between bacteria, including pathogenicity and/or virulence determinants. In the enteric pathogen Escherichia coli O157:H7, which causes hemorrhagic colitis and hemolytic-uremic syndrome, Shiga toxins 1 and 2 (Stx1 and Stx2) are phage encoded. The sequence and analysis of the

34. Amino acid substitutions in naturally occurring variants of ail result in altered invasion activity.
Yersinia enterocolitica is the causative agent of a variety of gastrointestinal syndromes ranging from acute enteritis to mesenteric lymphadenitis. In addition, systemic infections resulting in high mortality rates can occur in elderly and immunocompromised patients. More than 50 serotypes of Y. enterocolitica have been identified, but only a few of them com
