Suillus granulatus is a valuable wild edible mushroom with a strong umami taste.Different grades of S.granulatus were dried by different methods,including natural air drying(ND),hot air drying(HAD),vacuum drying(VD),and freeze drying(FD).Results showed that VD samples of all grades had the highest equivalent umami concentration(EUC)value(P<0.05).The second grade of ND samples showed the highest EUC value(P<0.05).The first grade of HAD samples showed the highest EUC value(P<0.05).The third grade of FD samples showed the highest EUC value(P<0.05).The third grade of VD samples had a higher EUC value than the other grades of samples dried by VD.Electronic tongue results indicated no significant differences between samples of all grades dried by all methods.Thus,umami taste components are affected by drying method and grade.VD is an appropriate drying method for all sample grades.ND,HAD,and FD are suitable for second-,first-,and third-grade samples,respectively. 展开更多

Objective: To identify different stages of Ixodes granulatus(I. granulatus) based on morphological characters prior to molecular identification which is significant for confirming and identifying the nymphal stages of I. granulatus.Methods: A total of 14 individuals of adult, engorged and nymphal ticks collected from three different localities were examined morphologically using taxonomic keys, followed by PCR using cytochrome oxidase subunit I(COI). Clustering analysis based on COI sequences was carried out by constructing neighbor-joining and maximum parsimony tree to clarify the genetic variation and diversity of local I. granulatus.Results: Based on external morphological characterizations, nine individuals(64.3%)were successfully identified as I. granulatus, while five individuals were recognized only as Ixodes sp. due to lack of morphological characters visible and development during that stage. Molecular analysis of local I. granulatus using COI gene revealed 93%–94% sequence homology from available sequence in Gen Bank and was in concordance with the morphological identification. Furthermore, a low intraspecific variation was observed among the species of I. granulatus collected from different localities(0%–3.7%).Conclusions: These findings demonstrated for the first time the establishment of COI gene for identifying I. granulatus nymphal tick which is of paramount importance to the control of potential tick-borne infections in Malaysia. Moreover, this study provides evidence that a combination of morphology and molecular data was corroborated as an accurate tool for tick identification. 展开更多

Objective:To identify the presence of acarine ectoparasites and determine whether there is any potential public health risk in Panti Forest Reserve,Johore,Malaysia.Methods:Trapping of animals and avifauna was conducted simultaneously along 5 expedition trails using 150 wire traps,10 harp traps and 30 mist nets for 6 consecutive nights.A total of 140 animals consisting of 7 species of birds,19 species of bats,6 species of rodents and 1 species of tree-shrew as well as 8 myriapods were examined.Results:Infestation rates of ticks,mesostigmatid mites and chiggers on animals examined were 24.3%,28.6%and 27.9%,respectively.Infestation on bats was low(1.5%) and none occurred on birds.Majority of ticks extracted were at immature stages(78.9%). Genera of ticks on animals were Amblyomma,Dermacentor,Haemaphysalis and Ixodes.Ixodes granulatus was the only species of licks identified from the animals.Examination of ticks under vegetation revealed 54%adults leading to identification of 3 species of ticks.A total of 7 species of mesostigmatid mites were found.6 species were on rodent,Maxomys mrifer and another one species,Laelaps nuttalli was found only on Leopoldamys sabanus.Laelaps sanguisugus was the only mesostigmatid found infesting tree-shrews.Seven genera of chiggers were identified.From this,5 genera were on rodents,4 genera on tree-shrews and 1 genus on a bat.Conclusions:A total of 16 genera,2 sub-genus and 14 species of acarine ectoparasites were found in this area. Findings of the survey demonstrate the presence of three spesies of acarine ectoparasites which have potential health risk i.e.Ixodes granulalus,Laelaps nuttalli and Leptotrombidium deliense. 展开更多
