Preliminary radiation hybrid map for river buffalo chromosome 6 and comparison to bovine chromosome 3

We present the first radiation hybrid (RH) map of river buffalo (Bubalus bubalis) chromosome 6 (BBU6) developed with a recently constructed river buffalo whole-genome RH panel (BBURH5000). The preliminary map contains 33 cattle-derived markers, including 12 microsatellites, 19 coding genes and two ESTs, distributed across two linkage groups. Retention frequencies for markers ranged from 14.4% to 40.0%. Most of the marker orders within the linkage groups on BBU6 were consistent with the cattle genome sequence and RH maps. This preliminary RH map is the starting point for comparing gene order between river buffalo and cattle, presenting an opportunity for the examination of micro-rearrangements of these chromosomes. Also, resources for positional candidate cloning in river buffalo are enhanced.

Isolation and identification of mycobacteria from livestock specimens and milk obtained in Brazil

The prevalence of Mycobacterium bovis and other mycobacterial species in livestock specimens and milk was evaluated. An emphasis was placed upon the distribution of these organisms in milk that is readily available to the public that was either untreated, pasteurized, or treated using ultra high temperature. Twenty-two pathologic specimens from livestock (bovine, swine and bubaline) in five Brazilian states and 128 bovine milk samples from retail markets in the State of São Paulo were examined for mycobacteria. Identification was made by classical biochemical tests, thin layer chromatography of mycolic acids and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Mycobacteria were isolated from 15 (68.2%) caseous lesions and from 23 (18%) milk samples. Eleven isolates were identified as M. bovis, and the remaining 27 nontuberculous mycobacterial isolates were represented by five species and six unidentified rapidly growing mycobacterial strains. The data demonstrate that animal products in Brazil are frequent reservoirs of mycobacteria and may pose a risk to the public.

Occurrence of toxigenic Escherichia coli in raw milk cheese in Brazil

Pesquisou-se a ocorrência de Escherichia coli toxigênica, em queijo produzido com leite não pasteurizado, na Região Centro Oeste do Brazil. Foram utilizados 50 queijos adquiridos em diferentes supermercados. As amostras isoladas foram classificadas por sorogrupo, avaliadas em relação à sensibilidade para 13 agentes antimicrobianos e submetidas à reação em cadeia da polimerase para a presença de genes característicos de E. coli verotoxigênica (VTEC) e enterotoxigênica (ETEC). E. coli foi recuperada em 48(96,0%) dos queijos. Foram identificados os sorogrupos O125 (6,0%), O111 (4,0%), O55 (2,0%) e O119 (2,0%). Três (6,0%) amostras de E. coli foram classificadas como VTEC e uma (2,0%) como ETEC. Os maiores índices de resistência foram verificados para: cefalotina (60,0%), ácido nalidíxico (40,0%), doxiciclina (33,0%), tetraciclina (31,0%) e ampicilina (29,0%).
