This review aimed to provide a comprehensive overview of ruminant and human fascioliasis in Malaysia and to identify research gaps in knowledge of the prevalence of fascioliasis in Malaysia and risk factors for the disease using available evidence-based data. We conducted a scoping review based on the framework of Arksey and O’Malley. The preferred reporting items for systematic reviews and meta-analyses were used to guide the review process. The citation search was performed between May and September 2018. Using specific keywords, literature published between 1998 to September 2018 was retrieved from electronic databases. Six articles related to fascioliasis in Malaysia were included in the final review from 1,932 screened articles and reports. Five studies focused on ruminants, including cattle, buffaloes, sheep and goats in the states of Terengganu and Perak. The most frequent ruminant fascioliasis outbreaks involved cattle and goats, with a prevalence of 82%–95% and these outbreaks occurred in Terengganu. Only one study examined the risk of fascioliasis in cattle. In the study, the age and sex of the cattle were important risk-related parameters. The search returned only one documented report of a suspected case of human fascioliasis with an atypical clinical presentation. At present, human fascioliasis in Malaysia remains under-reported and its prevalence remains unknown. The data summarised in this review based on existing evidence identifies research gaps on fascioliasis in ruminants and humans.

Aims: Quercus infectoria (QI) gall extract is known to have broad spectrum anti-microbial activity in vitro. However, its mechanism of microbial growth inhibition is not well understood. The objectives of this study were to determine the antimicrobial effect of methanolic QI gall extract on bacteria and yeast and changes to their cell morphology. Methodology and results: The minimum inhibitory concentrations (MICs) of methanolic QI gall extract against Streptococcus agalactiae (ATCC 13813), Proteus vulgaris (ATCC 49312) and Candida albicans (ATCC 10231) were determined using two fold serial microdilution technique at concentrations ranging from 0.01 mg/mL to 5.00 mg/mL (for bacteria) and 0.02 mg/mL to 12.00 mg/mL (for yeast). Minimum bactericidal concentration (MBC) and minimum fungicidal concentration (MFC) were determined by subculturing the broth from the microtitre wells which showed no apparent growth or turbidity onto the nutrient agar plates. The scanning electron microscope (SEM) was used to analyze the morphology of bacteria and yeast cells treated with 1× MIC and 4× MIC of the extract. Substantial antimicrobial activity was observed against ATCC strains of S. agalactiae, P. vulgaris and C. albicans in this study. The MBC/MFC to MIC ratio (≤4) indicated the methanolic QI gall extract was bactericidal and fungicidal against all the tested strains. Changes to the cell morphology were more obvious at higher extract concentration (4× MIC). Conclusion, significance and impact of study: This study showed that QI gall extract has antimicrobial effects on the bacterial and yeast cell morphology and thus, provides scientific information suggesting its possible antimicrobial mechanisms on the cell wall and membrane integrity.
