Abstract The differential display reverse transcriptional polymerase chain reaction (DD-RT-PCR) was used to hunt for cDNA fragments specifically expressed by taxol treatment of HeLa cells. Forty-eight cDNA clones were differentially displayed through the experiments. The cDNA fragments obtained were separately spotted onto glass slides to prepare a tailor-made DNA chip. The gene expression pattern of differentially displayed cDNA fragments were checked by DNA microarray analysis.

Aim: This study aimed to study the prevalence of the coinfection of enteric bacterial and viral pathogens, namely Escherichia coli, Salmonella, Rotavirus, and Picobirnavirus from fecal samples of pre-weaned piglets in Northeast region of India. Materials and Methods: A total of 457 fresh fecal samples were collected from piglets under 9 weeks old during 2013-2015 from organized (n=225) and unorganized (n=232) farms of Manipur, Meghalaya, Mizoram, and Nagaland. Samples were collected from diarrheic (n =339) and non-diarrheic (n=118) piglets including local indigenous (n=130) and crossbreed (n=327) piglets in different seasons during the study period. The samples were processed for the isolation of E. coli and Salmonella and detection of their putative virulence genes by polymerase chain reaction (PCR). Samples were also processed for the detection of Rotavirus and Picobirnavirus by RNA-polyacrylamide agarose gel electrophoresis and reverse transcriptase-PCR (RT-PCR). Results: A total of 11 (2.40%) samples were found positive for two or more coinfecting enteric bacterial and viral pathogens. All the 11 positive fecal samples were recovered from diarrheic piglets. Salmonella Typhimurium (enterotoxin, stn gene) and Picobirnavirus genogroup 1 were found to be more frequent as coinfecting agents. Coinfection was recorded higher in unorganized (3.87%) compared to organized farm (0.88%). Again, higher detection was recorded in crossbreed (2.75%) than local indigenous piglets (1.53%). The occurrence of coinfection was found to be more common during summer (4.68%) followed by winter (2.27%) season. Conclusion: The present study highlighted the significance of E. coli, Salmonella, Rotavirus, and Picobirnavirus as important diarrheagenic pathogens causing coinfection in piglets in Northeast region of India. Probably, this is the first systematic study of the coinfection of four important diarrheagenic bacterial and viral agents associated with piglet diarrhea in India.

ABSTRACT The major cytotoxic effect of the verotoxins (VTs) produced by strains of VT-producing Escherichia coli is the inhibition of host-cell protein synthesis, but VTs are also suspected to play a role in apoptotic cell signaling and cytokine release. Four differentially expressed genes, including mkp-1 (encoding mitogen-activated protein kinase phospatase 1), were detected by differential display reverse transcription-PCR (DD RT-PCR) stimulated by VT1 in Caco-2 cells. Northern blot analysis showed the induction ofmkp-1 mRNA 6 h after VT1 stimulation. Neither mutant VT1 (mutVT1), harboring two mutations in the A subunit (E167Q-R170L), nor cycloheximide induced mkp-1 mRNA, but mkp-1mRNA was detected with both wild-type VT1 (wtVT1) and anisomycin, a 28S rRNA inhibitor. Therefore, we concluded that the A subunit of VT1 was essential for mkp-1 induction. Increased amounts of phosphorylated c-Jun protein were also found with wtVT1 and anisomycin. Although the precise mechanism of induction of MKP-1 is unknown, we hypothesized that 28S rRNA not only was a sensor for ribotoxic stress, but also was involved in the signal cascade of MKP-1. This is the first report of detection by DD RT-PCR of cellular genes induced by bacterial toxins.

O etileno, conhecido, sobretudo, como o fitormônio da maturação de frutos, está envolvido em vários processos fisiológicos, atuando na regulação da expressão de grande número de genes. O clone parcial de cDNA ER49 foi previamente isolado mediante a técnica do "Differential Display". A obtenção e a análise da seqüência completa confirmaram as homologias significativas com fatores de elongação da síntese de proteínas do tipo Ts. Tais proteínas são responsáveis pela reciclagem do complexo EF-Tu•GDP, que atua na ligação do aminoacil-RNAt ao ribossomo. A predição da seqüência protéica permitiu a detecção de um peptídio sinal de endereçamento para a mitocôndria e dos domínios TS-N e EF-Ts. A modelagem da estrutura terciária mostrou que ER49 poderia interagir com EF-Tu•GDP, para promover a reciclagem de GDP em GTP. Estudos de expressão durante a maturação do fruto de tomate (Lycopersicon esculentum Mill.), var. Micro-Tom, foram realizados por RT-PCR, revelando que ER49 tem sua expressão induzida nos últimos estádios de maturação do fruto. Os resultados da análise do DNA genômico por Southern blot sugerem que ER49 faz parte de uma família multigênica de 2-3 elementos. Através de ER49, gene mitocondrial regulado pelo etileno, surgem novas perspectivas para o estudo da regulação de genes em nível pós-transcricional e de sua relação com o metabolismo respiratório.
