• Application of molecular biology in the detection pathogens and medical arthropods in Southern Vietnam

    Molecular biology is a part of biology; based on physiology, genetic and biochemical. Molecular biology studies about the shape, structure, and function of macromolecules that have important roles in the life, such as nucleic acids, proteins…. Molecular biology techniques are very diverse and also applied in many different fields, such as molecular diagnostics (PCR, molecular hybridization); production of active substances detecting or treating diseases (producing monoclonal antibodies, making proteins with biological activity ...); gene therapy (recombinant ...). The molecular biology applications which the earliest and most visible are the medical fields. Based on genetic engineering, medicine not only relies on clinical symptoms but also impacts to directly the true reason that cause the disease: genetic abnormalities. Molecular biology pervate almost the medicine field; inside, the most potents are diagnostic and preventive
  • Determine the Presence of Pathogens on Ticks in the Mekong Delta Region

    Tick-borne diseases are an emerging medical and veterinary problem. Ticks are implicated in the transmission of different pathogens such as viruses, bacteria, protozoa and filarial nematodes. However, up to now researches on these pathogens in Vietnam which has been limited, especially in the Mekong Delta region (Southwestern of Vietnam). We have collected 4763 tick individuals of 7 species. 5 genus. 2 families (Argas sp.. Apononmta crassipes, Aponomma gervaisi. Rhipicephalus (Rhipicephalus) haemaphỵsaloides, Rhipicephalus (Rh.) sanguineus, Boophilus microplus, Ixodes (Ixodes) granulatus) at 8 sites in the Mekong delta region on the rainy season and dry season from 2015 to 2016 which determine the presence of pathogens (Rickettsia spp. and Orientia tsutsugamushi) on ticks. A total of 1457 tick individuals which were subdivided into 299 samples, that determine the presence of Rickettsia spp. and Oriental tsutsugamushi. Initial results, we have determined the presence of pathogen on ticks.
  • Species and distribution of tick (Gamasoidea), chigger mite (Trombiculidae), mite (Gamasoidea) in Southern Vietnam

    A cross-sectional study was conducted from June to October 2015 and March to April 2016 on species and distribution of ticks (Ixodoidea), chigger mites (Trombiculidae) and Gamasid mites (Gamasoidea) in the Southern Vietnam. As a result, 8,992 of ticks, chigger mites and gamasid mites (26 species, 12 genera, 5 families) were collected, of which Ixodoidea had 5 species, 4 genera, 1 family; Trombiculidae had 9 species, 4 genera, 1 family; Gamasoidea had 12 species, 4 genera, 3 families. The most common species in the area were Rhipicephalus (Rh.) sanguineus, Rhipicephalus (Rh.) haemaphysaloides, Boophilus microplus, Ascoschoengastia (L.) indica, Gahrliepis (W.) chinensis, Gahrliepia (W.) parapacifica, Leptotrombidum (L) deliense, Laelaps (E.) echininus, Laelaps (E.) sedlaceki, Ornithonyssus bursa. The highest number of species (21 species) was discovered in Bu Gia Map National Part and the lowest number of species (10 species) was found in Thu Dau Mot town.
  • Several other medical arthropods in southern of Vietnam (Ticks, chigger mites, and gamasid mites)

    Study on medical arthropod is limited in Vietnam, some investigations have shown that medically important arthropods include ticks, chigger mites, gamasid mites and fleas which are relatively common in many regions of Vietnam. The Institute of Malariology - Parasitology - Entomology in Ho Chi Minh City conducted surveys to identify species composition and distribution of several medical arthropods in southern Vietnam and assessing for the presence of pathogens for humans and animals.
  • Dengue fever vectors in the southern of Vietnam

    The dengue (DF)/dengue hemorrhagic fever (DHF) are mosquito-borne diseases known to occur in the whole country.
    The disease was reported in the northern provinces of Ha Noi and Hai Phong since 1959, then the disease has become widely spread throughout Vietnam. And in recent years the disease has had a great impact on South Vietnam, where the geographical distributions of Ae. aegypti and Ae. albopictus overlap, where simultaneously DF/DHF, as well as malaria is presenting.
  • Malaria vectors in southern of Vietnam

    During the 20th century and the early years of the 21st century, malaria is a major public health problem in Vietnam, malaria was circulating in all regions, provinces, and cities in the country.
