Cotidiano e violência simbólica : a desconstrução do preconceito étnicorracial nas escolas.

A preocupação central desta pesquisa é analisar a concepção de cinco professores de unidades diferentes da rede municipal do Recife que vivenciam o preconceito étnicorracial nas salas de aulas. Elencamos o estudo bibliográfico do período XIX ao XXI referentes ao racismo no Brasil, o currículo escolar, a proposta da lei 10.639/03, a literatura apresentada pelos professores em relação a temática. O processo investigativo foi realizado com entrevistas aos professores do primeiro e segundo ciclo, aplicação de questionário aos estudantes na faixa etária entre sete aos quatorze anos, observação em sala de aula. Foi utilizada a metodologia quali-quantitativa. Sendo a análise do discurso e o programa SPSS 18.0. Utilizando uma tabela e gráficos. Observamos as questões do preconceito racial apontado pelos professores e seus estudantes, a reprodução de padrões etnocêntricos gerados pela mídia. Observamos que há a carência de uma formação acadêmica referente à Lei 10.639/03 para que estes profissionais consigam perceber atitudes de preconceito racial em suas salas de aulas e tenham subsídios para construírem atividades pedagógicas voltadas para a desconstrução do preconceito racial.

Corynebacterium suicordis sp. nov., from pigs

Nineteen strains of Gram-positive, non-motile, non-spore-forming, catalase-positive, rod-shaped bacteria isolated from pigs were characterized by using biochemical, molecular chemical and molecular genetic methods. Two distinct groups of organisms were discerned, based on their colonial morphology, CAMP (Christie-Atkins-Munch-Petersen) reaction and numerical profile by using the API Coryne system. The first group (113 strains) gave a doubtful discrimination between Corynebacterium striatum and Corynebacterium amycolatum, whilst the second group (six strains) were identified tentatively as Corynebacterium urealyticum. Comparative 16S rRNA gene sequencing studies demonstrated that all of the isolates belonged phylogenetically to the genus Corynebacterium. The first group of organisms was highly similar to Corynebacterium testudinoris with respect to 16S rRNA gene sequences and physiological characteristics, whereas the remaining six isolates formed a hitherto unknown subline within the genus, associated with a small subcluster of species that included Corynebacterium auriscanis and its close relatives. The unknown Corynebacterium sp. was distinguished readily from these and other species of the genus by biochemical tests. Based on both phenotypic and phylogenetic evidence, it is proposed that the new isolates from pigs should be classified as a novel species, Corynebacterium suicordis sp. nov. The type strain is P81/02(T) (=CECT 5724(T) =CCUG 46963(T)).

Neonatal mortality in puppies due to bacteremia by Streptococcus dysgalactiae subsp dysgalactiae

We report a case of bacteremia in puppies caused by Streptococcus dysgalactiae subsp. dysgalactiae. Identification was achieved by phenotypic and molecular genetic methods. This is the first report of the recovery of S. dysgalactiae subsp. dysgalactiae from dogs.

Uruburuella suis gen. nov., sp nov., isolated from clinical specimens of pigs

Five strains of an unusual Gram-negative, catalase-positive, oxidase-positive, coccobacillus-shaped bacterium isolated from the lungs and heart of pigs with pneumonia and pericarditis were characterized by phenotypic and molecular genetic methods. On the basis of cellular morphology and biochemical criteria, the isolates were tentatively assigned to the family Neisseriaceae, although they did not appear to correspond to any recognized genus or species. Comparative 16S rRNA gene sequencing showed that the five unidentified strains were phylogenetically highly related to each other and represent a hitherto unknown subline within the family Neisseriaceae. On the basis of both phenotypic and phylogenetic evidence, it is proposed that the unknown isolates from pigs be classified as a novel genus and species within the family Neisseriaceae, for which the name Uruburuella suis gen. nov., sp. nov. is proposed. The type strain of U. suis is 1258/02(T) (=CCUG 47806(T) =CECT 5685(T)).

Psychrobacter pulmonis sp nov., isolated from the lungs of lambs

Unusual Gram-negative, catalase- and oxidase-positive, coccus-shaped bacteria isolated from the lungs of two lambs were characterized by phenotypic and molecular-genetic methods. Comparative 16S rRNA gene sequencing studies demonstrated that the unknown isolates were genealogically highly related to each other (99.8% sequence similarity) and represent a novel subline within the genus Psychrobacter. The unknown bacterium was phylogenetically closely related to, but distinct from, Psychrobacter phenylpyruvicus, Psychrobacter immobilis, Psychrobacter glacincola and Psychrobacter urativorans. The novel Psychrobacter isolates were readily distinguished from all other Psychrobacter species and other Gram-negative, oxidase-positive bacteria usually responsible for lung infections in sheep by physiological and biochemical tests. Based on molecular-genetic and phenotypic evidence, it is proposed that the unknown Psychrobacter isolates from lambs be classified as Psychrobacterpulmonis sp. nov. The type strain is strain S-606(T) (= CECT 5989(T) = CCUG 46240(T)).

Corynebacterium spheniscorum sp nov., isolated from the cloacae of wild penguins

Twenty unidentified Gram-positive, rod-shaped organisms were recovered from the cloacae of apparently healthy wild penguins (Spheniscus magellanicus) and subjected to a polyphasic taxonomic analysis. On the basis of cellular morphology and biochemical criteria, the isolates were tentatively assigned to the genus Corynebacterium, although the organisms did not appear to correspond to any recognized species. Lipid studies confirmed this generic placement, and comparative 16S rRNA gene sequencing showed that the unidentified organisms represent a hitherto unknown subline, associated with a small subcluster of species that includes Corynebacterium diphtheriae and its close relatives. On the basis of phenotypic and phylogenetic evidence, it is proposed that the unknown isolates from penguins be classified in the genus Corynebacterium, as Corynebacterium spheniscorum sp. nov. The type strain is strain PG 39(T) (=CCUG 45512(T) =CECT 5986(T)).

Corynebacterium sphenisci sp nov., isolated from wild penguins

Six unidentified Gram-positive, rod-shaped organisms recovered from the cloacae of apparently healthy wild penguins were characterized by phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of a cell wall based on meso-diaminopimelic acid and long-chain cellular fatty acids of the straight-chain saturated and monounsaturated types, consistent with the genus Corynebacterium. Corynomycolic acids, which are characteristic of the genus, were also detected, albeit in small amounts. Comparative 16S rRNA gene sequencing studies showed that the unidentified organisms were phylogenetically related to corynebacteria and represent a novel subline associated with a small subcluster of species that includes Corynebacterium xerosis, Corynebacterium amycolatum and Corynebacterium freneyi. The unknown isolates were readily distinguished from their closest phylogenetic relatives and all other Corynebacterium species with validly published names by using a combination of biochemical and chemotaxonomic criteria. Based on both phenotypic and 16S rRNA gene sequence considerations, it is proposed that the unknown isolates recovered from penguins be classified as a novel species in the genus Corynebacterium, Corynebacterium sphenisci sp. nov. The type strain is CECT 5990(T) (= CCUG 46398(T)).

Isolation of Corynebacterium falsenii and description of Corynebacterium aquilae sp. nov., from eagles

Biochemical, molecular chemical and molecular genetic studies were performed on seven unidentified Gram-positive, rod-shaped organisms recovered from eagles. The strains were provisionally identified as Corynebacterium jeikeium with the commercial API Coryne system, but they were able to grow under anaerobic conditions and were non-lipophilic. Comparative 16S rRNA gene sequencing studies demonstrated that the isolates belonged phylogenetically to the genus Corynebacterium. Three strains were identified genotypically as Corynebacterium falsenii; the remaining four strains corresponded to a hitherto unknown lineage within the genus Corynebacterium, associated with a small subcluster of species that included Corynebacterium diphtheriae and its close relatives. The unknown bacterial strains were readily distinguished from these and other species of the genus by biochemical tests. Based on both phenotypic and phylogenetic evidence, it is proposed that the unknown bacterial strains from eagles should be classified as Corynebacterium aquilae sp. nov. (type strain is S-613(T)=CECT 5993(T)=CCUG 46511(T)).

Streptococcus equi subsp ruminatorum subsp nov., isolated from mastitis in small ruminants

Six isolates of an unknown Gram-positive, catalase-negative, chain-forming, coccus-shaped organism isolated from ovine and caprine mastitis were characterized by phenotypic and molecular taxonomic methods. On the basis of cellular morphology and the results of biochemical tests, the organism was tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed that the organism is a member of the genus Streptococcus, with Streptococcus equi as its closest phylogenetic relative (98(.)8% similarity). DNA-DNA pairing studies showed that the unidentified organism displayed more than 70% relatedness to the type strains of S. equi subsp. equi and subsp. zooepidemicus. Despite the relatively high DNA-DNA reassociation values, biotyping and ribotyping allowed clear differentiation of the unknown bacterium from the two recognized subspecies of S. equi. On the basis of phenotypic and molecular genetic evidence, it is proposed that the unknown Streptococcus isolates from ovine and caprine mastitis be classified as a novel subspecies, Streptococcus equi subsp. ruminatorum subsp. nov. The type strain is CECT 5772(T) (=CCUG 47520(T) = Mt 167(T)).
