Medicinal plants are used in herbalism. They form the easily available source for healthcare purposes in rural and tribal areas. In the present review, an attempt has been made to congregate the phytochemical and pharmacological studies done on an important medicinal plant Aegle marmelos. Extensive experimental and clinical studies prove that Aegle marmelos possesses antidiarrhoeal, antimicrobial, antiviral, radioprotective, anticancer, chemopreventive, antipyretic, ulcer healing, antigenotoxic, diuretic, antifertility and anti-inflammatory properties, which help it to play role in prevention and treatment of many disease. Therefore, it is worthwhile to review its therapeutic properties to give an overview of its status to scientist both modern and ancient. This review also encompasses on the potential application of the above plant in the pharmaceutical field due to its wide pharmacological activities. © 2014 Asian Pacific Tropical Medicine Press.

This study was undertaken to compare and evaluate the parameters of 10 different mathematical models for their predictive ability in describing the lactation curves for daily milk yield of different genotypes under cooperative dairying in Bangladesh. A database consisting of 7340 herd-test records from 738 cows over the period 1999-2001 was assembled. Breed combinations included Pabna cattle, Australian-Friesian-Sahiwal×Pabna, Holstein×Pabna, Jersey×Pabna and Sahiwal×Pabna. The estimated parameters of the mathematical models, and the predicted lactation milk yields differed significantly between genotypes. The models were evaluated by four fit statistics: Akaike information criteria, coefficient of determination (R 2), root mean square prediction error (RMSPE) and concordance correlation coefficient (CCC). The AIC values indicated that the Ali model provided a good fit for all genotypes. The R 2 value suggested that the Legendre polynomial and Ali models were the best fit for all genotypes. CCC and RMSPE values indicated that the best models for all genotypes were Nelder and Wood. Since the CCC value was considered the most informative of the four fit statistics, the Nelder model was the best model to predict the full lactation profile based on test-day records for all genotypes. Using the Nelder model, the predicted 270 day milk yield of the Australian-Friesian- Sahiwal×Pabna genotype was higher (1823 kg) than the other genotypes (1509, 1650, 1531 and 1627 kg for Pabna, Australian-Friesian- Sahiwhal×Pabna, Jersey×Pabna and Sahiwal×Pabna, respectively). © 2012 Taylor and Francis.

Until recently, Cryptosporidium was thought to be a single species genus. Molecular studies now show that there are at least 10 valid species of this parasite. Among them, two morphologically identical species, C. hominis and C. parvum are the most pathogenic identified to date and share 97% of identical genomes. Post-genomic analyses is therefore necessary to explore further the genetic variations among them. During this study, a comparative proteomic approach was applied to analyze the differential expression of sporozoite proteins in both C. hominis and C. parvum. Using 2-DE gels with different pH ranges (3-10 and 4-7) and automated three dimensional (3D) image analyses, a total of 20 protein spots were shown to be differentially expressed between the two species. Mass spectrometry analyses of these spots identified one hypothetical protein, however, identification of the remaining spots was unsuccessful. Further characterization of this hypothetical protein along with all differentially expressed proteins could provide crucial information in understanding the differential biology of Cryptosporidium spp.

We investigated faecal samples collected from the rectum of 518 cattle on 371 randomly selected smallholdings in Bangladesh for the presence of sorbitol non-fermenting (SN-F) shiga toxin-producing Escherichia coli (STEC). The SN-F isolates were tested for the presence of rfb O157, stx1, stx2, eae and hlyA genes by polymerase chain reaction (PCR). Seven SN-F isolates lacking these genes were profiled by pulsed-field gel electrophoresis (PFGE) to verify their clonality. SN-F E. coli was identified in 44 [8·5%, 95% confidence interval (CI) 6·4-11·2] samples; of these, 28 (5·4%, 95% CI 3·8-7·7) had shiga toxin-producing strains, although only two carried the rfb O157 gene. Thirteen isolates carried the hlyA gene while 18 harboured the eae gene. Based on PFGE, six pulsotypes were observed among the seven isolates that had no virulence genes. To the best of our knowledge this is the first report on shiga toxin-producing E. coli from direct rectal faecal samples of cattle on smallholdings. © Cambridge University Press 2014.

Background: Escherichia coli O157 (EcO157) infection has been recognized as an important global public health concern. But information on the prevalence of EcO157 in cattle at the global and at the wider geographical levels is limited, if not absent. This is the first meta-analysis to investigate the point prevalence of EcO157 in cattle at the global level and to explore the factors contributing to variation in prevalence estimates. Methods: Seven electronic databases- CAB Abstracts, PubMed, Biosis Citation Index, Medline, Web of Knowledge, Scirus and Scopus were searched for relevant publications from 1980 to 2012. A random effect meta-analysis model was used to produce the pooled estimates. The potential sources of between study heterogeneity were identified using metaregression. Principal findings: A total of 140 studies consisting 220,427 cattle were included in the meta-analysis. The prevalence estimate of EcO157 in cattle at the global level was 5.68% (95% CI, 5.16-6.20). The random effects pooled prevalence estimates in Africa, Northern America, Oceania, Europe, Asia and Latin America-Caribbean were 31.20% (95% CI, 12.35-50.04), 7.35% (95% CI, 6.44-8.26), 6.85% (95% CI, 2.41-11.29), 5.15% (95% CI, 4.21-6.09), 4.69% (95% CI, 3.05-6.33) and 1.65% (95% CI, 0.77-2.53), respectively. Between studies heterogeneity was evidenced in most regions. World region (p<0.001), type of cattle (p<0.001) and to some extent, specimens (p = 0.074) as well as method of pre-enrichment (p = 0.110), were identified as factors for variation in the prevalence estimates of EcO157 in cattle. Conclusion: The prevalence of the organism seems to be higher in the African and Northern American regions. The important factors that might have influence in the estimates of EcO157 are type of cattle and kind of screening specimen. Their roles need to be determined and they should be properly handled in any survey to estimate the true prevalence of EcO157. © 2014 Islam et al.
