Echinococcus ortleppi infection in humans: An emerging zoonosis in Asia.

Echinococcus ortleppi is the genotype G5 of Echinococcus granulosus sensu lato and is a zoonotic canine tapeworm of which larvae causes cystic diseases in domestic animals and also humans. While this species is highly endemic and widely spread in domestic animals, human infection is extremely rare and only sporadic, and thus, entire picture of human cystic echinococcosis due to infection with E. ortleppi is unclear.

Effects of Spore Ratios on Fruiting Body Formation and Degeneration in the Heterothallic Fungus .

The medicinal mushroom is widely exploited in traditional medicine and nutraceuticals in Asian countries. However, fruiting body production in is facing degeneration through cultivation batches, and the molecular mechanism of this phenomenon remains unclear. This study showed that fruiting body formation in three different strains, namely G12, B12, and HQ1, severely declined after three successive culturing generations using the spore isolation method.

First Molecular Evidence of Pathogens in Fleas Collected from Dogs in Northern Vietnam.

Fleas are considered as hosts for a wide range of pathogens that cause emerging and re-emerging zoonotic diseases worldwide. Data on fleas and flea-borne pathogens (FBPs) in the international literature are limited in Vietnam. This study aimed to investigate the species of fleas and the presence of pathogens of interest in fleas in northern Vietnam using PCR and sequence analysis.

A case of Trypanosoma evansi in a German Shepherd dog in Vietnam.

A 2.5-year-old male German Shepherd was presented to a private veterinary clinic in Hanoi, Vietnam showing anorexia, weakness, lethargy, reluctant to go for walks with a recent history of intermittent fever. Clinical examination of the dog showed pale mucous membrane, impaired eyesight, edema of the back legs.

Molecular detection of pathogens in ticks and fleas collected from companion dogs and cats in East and Southeast Asia.

Background: Ticks and fleas are considered amongst the most important arthropod vectors of medical and veterinary concern due to their ability to transmit pathogens to a range of animal species including dogs, cats and humans. By sharing a common environment with humans, companion animal-associated parasitic arthropods may potentially transmit zoonotic vector-borne pathogens (VBPs). This study aimed to molecularly detect pathogens from ticks and fleas from companion dogs and cats in East and Southeast Asia.

Anaplasma marginale and A. platys Characterized from Dairy and Indigenous Cattle and Dogs in Northern Vietnam.

Anaplasma marginale and A. platys were detected and characterized (16S rDNA sequence analysis) from dairy and indigenous cattle, and the latter in domestic dogs in Vietnam. A phylogenetic tree was inferred from 26 representative strains/species of Anaplasma spp.

Ticks and associated pathogens from dogs in northern Vietnam.

The medical and veterinary significance of ticks and tick-borne pathogens (TBPs) in tropical and subtropical zones is well recognized. Although ticks and TBPs are known to occur in Southeast Asia, limited data is available in the international literature for some countries, such as Vietnam. The aim of this study was to investigate the species of ticks and TBPs associated with dogs in northern Vietnam.

Prevalence, genotyping and risk factors of Giardia duodenalis from dogs in Vietnam.

This study was carried out to determine the prevalence, genotypes/assemblages and possible risk factors associated with Giardia duodenalis infection in dogs in central Vietnam. A total of 209 dog fecal samples, randomly collected from private owned dogs (n=105) and dogs from stores (n=104), were examined for Giardia cysts by microscopy. Positive samples were genotyped by PCR-sequence analysis of β-giardin and triosephosphate isomerase genes markers.

Updated molecular phylogenetic data for Opisthorchis spp. (Trematoda: Opisthorchioidea) from ducks in Vietnam.

Background: An opisthorchiid liver fluke was recently reported from ducks (Anas platyrhynchos) in Binh Dinh Province of Central Vietnam, and referred to as "Opisthorchis viverrini-like". This species uses common cyprinoid fishes as second intermediate hosts as does Opisthorchis viverrini, with which it is sympatric in this province. In this study, we refer to the liver fluke from ducks as "Opisthorchis sp.
