An outbreak of sheep associated malignant catarrhal fever in crossbred cattle in a village of Andhra Pradesh, southern India, affected thirteen adult cows and two calves from a population of forty animals. All the affected animals were died between December and January 2013–14. The clinical and gross postmortem findings were typical of MCF in Indian crossbred cattle. Migrating sheep flocks were suspected source of infection for the cattle. The diagnosis was confirmed by heminested PCR in all the affected cattle and the suspected sheep flock. The PCR provided evidence of ovine herpes virus type 2. 相似文献

Effect of experimentally induced thyroxine overdose on the testis and seminal vesicles was studied in the air-breathing catfish,
Clarias gariepinus during the preparatory and the pre-spawning phase. The present study revealed a marked reduction in testosterone level in
serum, testis and seminal vesicles (SV). Histological examination showed a considerable reduction in the number of spermatozoa/spermatids
in the seminiferous tubular lumen as well as depletion of fluid in the loculi of SV. SDS-PAGE analysis of SV fluid proteins
demonstrated a significant decrease in the level of a ~27 kDa protein in thyroxine treated fishes. Evidences are presented
here to indicate that thyroid hormone plays a role in regulating testis and SV function in catfish.

New icetexane diterpenes (1-2); 8, 11, 13-icetexatriene-10-hydroxy, 11, 12, 16-tri acetoxyl (1) and 8, 11, 13-icetexatriene-7, 10, 11-dihydroxy-12, 13-dihydrofuran (2) along with six known compounds namely acetoxy syranzaldehyde (3), syranzaldehyde (4), coniferaldehyde (5), lupeol (6), betulin (7), and 4-(4-methoxy phenyl)-2-butanone (8) were isolated from the roots of Premna tomentosa. The structures of compounds 1 and 2 were established by detailed spectral analysis using UV, IR, 1H NMR, 13C NMR, 1D, 2D and Mass. The newly isolated compounds were screened for rat intestinal α-glucosidase inhibitory and free radical (DPPH) scavenging potentiality. The new icetexane diterpenes (1, 2) and compound 3 were found to have significant α-glucosidase inhibitory and also free radical scavenging (DPPH) activities. 相似文献

In this study we present the first report on partial amplification, sequencing and phylogenetic relationship of VP2 of the Indian isolate BTV-2. A PCR product of 1135 bp was amplified, cloned and sequenced. About 1063 bp of partial VP2 gene (1792-2854 bp region) of the Indian isolate was subjected to sequence analysis with already published sequences available in the genome database. The percent similarity of 85.2 was observed with Taiwan isolate and 59% with other isolates of BTV-2. However, 46.2% similarity with Australian BTV-1 and no significant similarity were noted with other serotypes. In-silico analysis and restriction enzyme digestion confirmed the presence of conserved SalI site at 2380 bp position in both Indian and Taiwan isolates. Phylogenetic analysis showed that all BTV-2 isolates formed one distinct group in which BTV-2 Indian and Taiwan isolate is more closely related and further demonstrated that BTV’s of the same serotype from different geographical regions were closely related at nucleotide and amino acid level, respectively. 相似文献
