Introduction Tong Nibong is a Bidayuh village located at Sarawak Kalimantan border.
Since the year 2004 to 2009, a total of 537 cases of malaria were recorded in
Serian District of which 14 cases were reported from Kampung Tong
Nibong. Community empowerment programme for malaria infection
prevention showed tremendous improvement in implementation. This
intervention study aims to gauge the effectiveness of community
empowerment approach in malaria elimination programme in Kampung Tong
Nibong Serian.
Methods An intervention study was conducted with pre and post data collection. Data
was collected using validated questionnaire by face to face interview.
Universal sampling method was used to select respondents from head of
household and post data was collected after intervention activities were
carried out within a year of study period.
Results The study showed significant difference on level of knowledge of
respondents on vector of malaria between pre and post data with a P < 0.05.
There was significant difference between pre and post data on practices on
control and prevention of malaria with a P < 0.05. The same goes to level of
positive attitude of respondents towards malaria control.
Conclusions In conclusion, the study can be considered successful because there is
significant difference in knowledge, attitude and practice among the
respondents between pre and post data. This indicates that community
empowerment (voluntary participation) measures can be implemented in high
risk or endemic areas where malaria is a persistent problem to the community
and health institutions faces many limiting factors.

A new innovation has been created which is called AUTOMATIC MEAT SLICING (AMS) MACHINE. The main purpose of the machine creation is to replace the old-style method in slicing the chicken meat to modern method. BABARITTOS DELIGHT supplies Tortillas Wrap to the latest trend of Food & Beverage (F&B) business called Food Truck. The main ingredient of Burritos is slices of boneless chicken meat, where each slice is approximately has to be 5 mm thick. Formerly, the slicing procedure used a normal cutting knife and its production rate was truncated as the demands of the Burritos are going higher by days. This method requires 3 to 4 workers to team up to complete the 30 kg boneless chicken meat to be cut into roughly 5 mm per slice within one and half hour. The AMS machine is predominant to help the company to grow the output of sliced meat and at the same time can reduce the number of workers. The usage of AMS machine is only required one worker for the operation and the output can be up to 30kg per 30mins, which is actually can end up almost 3 times quantity of output and 3 times labor cost-saving. Meanwhile the quality of the sliced meat is much enhanced as most of the slice meat is precisely 5mm thick. The AMS concept design is cutting the meat using several circular cutting blades, where the chicken will be put on the moving conveyor and finally will fall onto the hygienic tray.
Ariid catfishes, belong to family Ariidae is considered as one of the taxonomically problematic groups, which is still under review by fish taxonomist globally. Species level identification of some ariids often resulted in species misidentification because of their complex characters and very similar morphological characters within genera. A vigilant and detail observation is very important during the species level identification of ariid species. In these contexts, this study was carried out in order to determine the morphological variations of one of the ariid genera, Plicofollis, which have been giving misleading taxonomic information in the south-east Asian countries. A Truss network technique was used throughout the study period. The study was conducted based on 20 truss measurements using 22 to 23 specimens per species, namely P. argyropleuron, P. nella and P. tenuispinis found in Peninsular Malaysian waters. Morphological variations were determined using a multivariate technique of discriminant function analysis (DFA). The results obtained in this study showed that discriminant analysis using truss network measurements has produced very clear separations of all the species in Plicofollis group. Several important morphological characters have been identified, which represent body depth and caudal regions of the fish. The documentary evidences of these variables could be considered as the constructive functional features, which could enable us to assess more accurately to distinguish the species within this complex Ariidae family.
Cobia Rachycentron canadum, is one of the emerging aquaculture species but is usually a non-target resource in fisheries
industry and within Malaysia, their landings are among the highest worldwide. Identification of stocks with unique
morphological characters is important for effective management and sustainable utilization. Morphometric variations
among three different cobia populations from Kedah, Terengganu and Johor were studied. All the morphometric
characteristics varied among the three populations as all the elements of the first Eigen vector were positive. Discriminant
analysis suggested that head depth (HD) and maximum body depth, (MaxD) were the most varied among the populations.
Cobia populations from Kedah and Johor were in a single cluster in the dendrogram with a 63.69% similarity while
Terengganu was in another cluster with a similarity of 8.01% from Kedah and Johor. The differences in the observed
morphometry may be resulted from different trophic activities and/or habitat productiveness explored by each of the
populations
Wild stocks of endangered mrigal carp, Cirrhinus cirrhosus (Bloch 1795), continues to decline rapidly in the Indo-Ganges river basin. With an objective to evaluate its population status, landmark-based morphometric and meristic variations among three different stocks viz., hatchery (Jessore), baor (Gopalganj) and river (Faridpur) in Bangladesh were studied. Significant differences were observed in 10 of the 15 morphometric measurements viz., head length, standard length, fork length, length of base of spinous, pre-orbital length, eye length, post-orbital length, length of upper jaw, height of pelvic fin and barbel length, two of the 8 meristic counts viz., scales above the lateral line and pectoral fin rays and 10 of the 22 truss network measurements viz., 1 to 10, 2 to 3, 2 to 8, 2 to 9, 2 to 10, 3 to 4, 3 to 8, 4 to 5, 4 to 7 and 9 to 10 among the stocks. For morphometric and landmark measurements, the 1st discriminant function (DF) accounted for 58.1% and the 2nd DF accounted for 41.9% of the among-group variability. In discriminant space, the river stock was isolated from the other two stocks. On the other hand, baor and hatchery stocks formed a very compact cluster. A dendrogram based on the hierarchical cluster analysis using morphometric and truss distance data placed the hatchery and baor in one cluster and the river in another cluster and the distance between the river and hatchery populations was the highest. Morphological differences among stocks are expected, because of their geographical isolation and their origin from different ancestors. The baseline information derived from the present study would be useful for genetic studies and in the assessment of environmental impacts on C. cirrhosus populations in Bangladesh.

Pengimejan tradisi mempunyai banyak kekurangan seperti mempunyai jangka hayat yang pendek serta bersaiz besar
kerana sifat pendafluornya tidak tahan lama atau berlakunya pelunturanfoto. Melalui kajian ini, nanohablur kadmium
sulfida dihasilkan dan berfungsi sebagai pengimejan titik kuantum yang sesuai dengan sifat optiknya yang pelbagai
mengikut saiz zarahnya. Sifat optik titik kuantum kadmium sulfida (TK CdS) boleh dipengaruhi oleh saiz dan juga
komposisi kimia TK seperti perubahan pH. Dalam kajian ini, sifat optik TK CdS dikaji terhadap perubahan nilai pH
dengan menghasilkan TK CdS melalui kaedah koloidal. Kadmium asetat dihidrat (C4
H6
CdO4
.2H2
O) dan natrium sulfida
(Na2
S) digunakan sebagai sebagai bahan pemula bagi menghasilkan TK CdS. Nilai pH diubah suai dengan menitiskan
natrium hidroksida (NaOH) ke dalam larutan TK CdS. Lima jenis larutan disediakan iaitu pada nilai pH5, pH7, pH8,
pH9 dan pH10. Masalah penggumpalan sering berlaku semasa proses sintesis CdS. Oleh itu, kajian ini menggunakan
asid tioglikolik (HSCH2
CO2
H) sebagai agen penstabil kepada TK CdS. Spektra keserapan UV memberi anjakan biru
apabila TK CdS pada pH alkali kerana saiz nanohablur mengecil. Hasil daripada spektroskopi pendarfluor mendapati
larutan yang mempunyai nilai pH8 memberi puncak yang tertinggi. Hal ini adalah kerana pada pH ini nanohablur
mampu berubah pada posisi yang tepat dan membentuk TK CdS pada kehabluran yang tinggi. Oleh itu, mekanisme ini
dapat membentuk perangkap lubang dan seterusnya eksiton terbentuk.
The aim of the present work was to produce a new soy milk-based cake. Soy milk was added at different percentages (0, 25, 50, 75, and 100%) during cake making to replace milk. Nutritional composition, batter characteristics, physical, and sensory properties, as well as the stability of cake during storage, were investigated. Sensory results indicated that cake with 50% soy milk had the most favourable acceptance scores with the highest score in the aroma, colour, and taste attributes. The addition of soy milk up to 50% produced a cake with higher protein content and lower carbohydrate content, along with lower density and higher specific volume compared to control. Cake with 50% soy milk addition had lower microbial counts as compared to control. Therefore, soy milk has the potential to act as a milk replacer in cake production.
An estuarine species of Nereididae (Annelida), Neanthesglandicincta (Southern, 1921) has been newly recorded on the eastern coast of Peninsular Malaysia located in the South China Sea based on 23 specimens collected from three estuaries (Tumpat, Kelantan Delta, Kelantan; Setiu Lagoon, Terengganu; Kuala Ibai, Terengganu). The morphological characteristics of the Malaysian specimens agree well with those of the previous original description and the redescription of N.glandicincta based on Indian, Myanmar and Singapore specimens. The number of paragnaths in all groups on the proboscis of our Malaysian specimens is within the range of the intraspecific variation of N.glandicincta as shown in the previous descriptions. An identification key to species of the Neanthesglandicincta species complex, which includes two morphologically similar species, is provided.
The genus Orientalicesa has six species, and all of them have been recorded in the Oriental region (including Indonesia, Malaysia, Phillippines, Laos, China). In this paper, the genus Orientalicesa is newly recorded from Vietnam, represented by one species O. confasciatus Tan and Carpenter. This species was mistakenly redescribed as Stenodyneriellus rangpocus Kumar, Carpenter Kishore, 2017. A new synonym of O. confasciatus is proposed, and that species is a new record for India.
This is the first report of new Plasmodium species (later known as P. knowlesi, after its discoverer) in a long-tailed macaque (Macaca fascicularis) imported to India from Singapore.

The genus Onchocerca includes 34 described species and represents one of the largest genera of the filarial nematodes within the family Onchocercidae. Representative members of this genus are mainly parasites of ungulates, with some exceptions such as Onchocerca lupi and Onchocerca volvulus, infecting carnivores and/or humans. For a long time, the evolutionary relationships amongst onchocercids remained poorly studied, as the systematics of this genus was impaired by the high morphological variability of species included in the taxon. Although some molecular phylogenies were developed, these studies were mainly focused on bovine Onchocerca spp. and O. volvulus, including assessments of Wolbachia endosymbionts. In the present study, we analysed 13 Onchocerca spp. from a larger host spectrum using a panel of seven different genes. Analysis of the coxI marker supports its usefulness for the identification of species within the genus. The evolutionary history of the genus has been herein revised by multi-gene phylogenies, presenting three strongly supported clades of Onchocerca spp. Analyses of co-evolutionary scenarios between Onchocerca and their vertebrate hosts underline the effect of domestication on Onchocerca speciation. Our study indicates that a host switch event occurred between Bovidae, Canidae and humans. Cophylogenetic analyses between Onchocerca and the endosymbiotic bacterium Wolbachia indicate the strongest co-evolutionary pattern ever registered within the filarial nematodes. Finally, this dataset indicates that the clade composed by O. lupi, Onchocerca gutturosa, Onchocerca lienalis, Onchocerca ochengi and O. volvulus derived from recent speciation.
Skin abrasions often occur in farmed fish following handling by labourers, injury by farm facilities, cannibalism and ectoparasites. Vibrio spp. are opportunistic pathogens that can invade host fish through damaged tissues and cause outbreaks of vibriosis. This study describes the effect of skin abrasions on the infectivity of V. harveyi using Asian seabass Lates calcarifer (Bloch, 1790) fingerlings as a case example and compares bacterial load and fish survival following immersion challenge with different doses. In total, 315 fish (6.67 ± 1.8 g) were divided into 3 treatments: skin abrasion followed by immersion infection, immersion infection only and an uninfected, uninjured control. Fish in the infection treatments were divided into 3 subgroups and exposed in triplicate to a 7 d immersion challenge with 106, 107 and 108 CFU ml-1 of live V. harveyi. No mortalities were observed in the control and immersion infection groups. However, fish in the skin abrasion treatment group that were infected with 108 CFU ml-1 of live V. harveyi showed signs of progressing disease throughout the experiment, which resulted in mortalities. Significantly higher bacterial loads (p < 0.05) were recorded in the intestine, liver and gills of the fish in this group. Fish in the skin abrasion treatment that were exposed to 107 and 108 CFU ml-1 of V. harveyi showed 100% mortality by Days 5 and 4, respectively. These findings confirm that skin injuries increase the susceptibility of seabass fingerlings to V. harveyi infection.
A list of mosquitoes collected from Lao People's Democratic Republic (Lao PDR) from May 2002 to August 2004 is presented. A total of 8,945 mosquitoes belonging to 14 genera and 57 species was collected. The genera recorded were Aedes, Anopheles, Armigeres, Coquillettidia, Culex, Diceromyia, Downsiomyia, Fredwardsius, Mansonia, Neomelaniconion, Ochlerotatus, Paraedes, Stegomyia, and Verrallina. Seventeen species are first reports for LAO PDR.
The present study aims to investigate the susceptibility status of Aedes albopictus, Culex quinquefasciatus, and Cx. vishnui collected from a pig farm in Tanjung Sepat, Selangor, toward 11 insecticides representing the classes of organochlorines, carbamates, organophosphates, and pyrethroids. The results of a World Health Organization adult mosquito bioassay revealed that Ae. albopictus, Cx. quinquefasciatus, and Cx. vishnui exhibited different susceptibility toward various insecticides. Overall, pyrethroids were able to induce rapid knockdown for all test mosquito species. The pyrethroids lambdacyhalothrin and etofenprox were able to cause high mortality (> 80%) of all 3 species. The findings of the present study will benefit local authorities in selecting appropriate dosage of insecticides to be used in mosquito control in this area.
