Abstract

Malaria and Dengue Haemorrhagic Fever (DHF) are two major tropical diseases in East Java. The pathogens of these diseases are transmitted to human hosts via haematophagy by vector mosquitoes. Anopheles spp. specifically transmits Plasmodium parasites which cause Malaria, while Aedes spp. transmits Dengue viruses that cause DHF. Bangsring, Banyuwangi is one of the endemic areas of Malaria, while Jember is one of endemic areas of DHF. Two species of Malaria vectors i.e Anopheles vagus and Anopheles sundaicus have been found from several samplings which were conducted in Bangsring region. This mosquitoes have been previously identified as a major vector for malaria. Aedes aegypti and Aedes albopictus, which were major vectors for DHF, have been easily found in Jember during our sampling for any season of the year. This research wanted to differentiate the morphological characteristic of those vectors for malaria and Dengue. Adult mosquitoes can be distinguished from one another by characterizing their morphological features. Palpi, wings, and legs characteristics are commonly used as determination keys in Anopheles sp., while thoraxes and legs characteristics are used as identification keys in Aedes sp. Morphological identification is considered as the basic necessity in understanding and determining bionomic of mosquito vector. This is very important in developing effective and efficient mosquito vector control strategies, which is also an important step to prevent the death risks associated with Malaria and DHF cases.

Abstract

Aedes albopictus mosquito is a potential vector for Dengue Haemorrhagic Fever (DHF) which transmits Dengue virus during blood feeding. The success of the blood feeding process is aided by the biological activity of proteins in the salivary glands of Aedes albopictus. There are 30 types of proteins from the salivary glands of Aedes albopictus which are carried along blood feeding process. Proteins in the salivary glands act as vasodilator and immunomodulator. Previous studies have identified two immunogenic proteins from the salivary glands of Aedes albopictus with molecular weight of 31 and 67 kDa. Further research on the biological function of these proteins requires its purified protein to better specify the target to developing a dengue vaccine. The objective of this study was to obtain 31 and 67 kDa purified proteins by implementation of electroelution and dialysis purification. The 31 and 67 kDa protein was successfully purified by this method. This has been confirmed by a single band visualization after SDS-PAGE analysis

Abstract

Cardiovascular disease is caused by impaired heart and blood vessel function. Coronary heart disease includes acute coronary syndrome due to narrowing of the coronary arteries. Aspirin is an anti-platelet drug which is commonly used for primary and secondary prevention of coronary heart disease. The effectiveness of aspirin has limitations because 10-20% of patients who use aspirin continue to experience vascular blockage. The haematophagus arthropods salivary glands contain apyrase which can inhibit platelet aggregation and thus a potential candidate for anti-platelet drug discovery. Our studies from salivary gland protein extract of Aedes albopictus found a 67 kDa protein fraction which has a similar molecular weight range from the previously identified apyrase of other mosquitoes vectors. The purpose of this study was to determine the apyrase potential capacity of 67 kDa protein fraction from salivary gland of Ae. albopictus. The present study employed inhibition percentage of platelet aggregation method in determining its apyrase activity. Aspirin was used as a positive control with 2 different concentrations of 0.1 mg/mL and 2 mg/mL. PBS 1mM pH 7.4 was used as a negative control treatment, while negative control without treatment only involved the addition of PRP and ADP. The inhibition percentage activity from the 67 kDa sample ranged from 3-37% whereas the total protein extract comprised of only 1%. The positive control of aspirin was 0.1 mg/mL and 2 mg/mL, resulting in inhibition percentage of 5% and 17%, respectively. The data showed that the inhibition percentage of platelet aggregation from protein 67 kDa is generally higher than those of total salivary gland protein extract as well as positive control. This indicated that the 67 kDa protein has a potential apyrase activity.

Abstract

Malaria is a public health threat caused by the Plasmodium infection transmitted by the Anopheles mosquito. Malaria vector control is highly dependent on the ability to determine mosquito species' vectorial and bionomic capacity. Species identification based on morphological characteristics as well as DNA-barcoding approaches is a very important step in determining vectorial capacity. Our research group has redesigned a new ITS2 primer, namely, sma-its2, which is specifically able to identify the Anopheles (An.) mosquito vector but cannot identify other mosquito vectors. This study wanted to test this primer's specificity further for identification of other Anopheles mosquitoes. We used An. minimus collected from Kulonprogo, Yogyakarta – Indonesia. The methods used in this research are as follows: landing collection, morphological identification, isolation of genomic DNA, PCR (Polymerase Chain Reaction), PCR product purification, sequencing, and data analysis. An. vagus from Bangsring, Banyuwangi – Indonesia, which had previously been identified using the same primary, was used as a positive control. The results of the morphological analysis showed that both species were in accordance with the vector identification key used in this study. The molecular analysis showed that the sma-its2 primer could amplify the ITS2 sequence of An. vagus and An. minimus, producing 650 – 700 bp. However, further analysis of the ITS2 sequences of both species, resulted in the same species, namely An. vagus, with a different accession number in GenBank. This showed that the sma-its2 primar can be used to identify An. vagus but cannot be used to identify An. minimus. Analysis of the primer position in the ITS2 sequences showed the presence of 3 nucleotides in the forward sma-its2 primer that was not recognized by the An. minimus sequences and thus, hinder the successful identification of these species.
