A total of 130 rodents comprising 8 species of hosts were captured and examined for ectoparasites. The hosts examined were Bandicota indica, Bandicota savilei, Rattus losea, Rattus rattus, Rattus exulans, Rattus norvegicus, Menetes berdmorei and Tamiops mcclellandii. Ninety-seven ectoparasites were collected: 1 species of tick (Hemaphysalis bandicota), 2 species of mites (Laelaps nuttali and Laelaps echidninus), and 1 species of flea (Xenopsylla cheopis) were identified. The infestation rates by ticks, mites and fleas on the rodents were 0.77, 5.38 and 6.15%, respectively. Monitoring the rodent population and their ectoparasites is important for future planning of prevention and control of zoonotic diseases in the area.

The animals were physical and ophthalmic examined during routine annual health check in February, 2013. All of them appeared in normal condition and had no signs of illness. Their blood was tested negative for feline leukemia virus, feline immunodeficiency virus, feline infectious peritonitis virus and Toxoplasma gondii using molecular detection of viral antigen. The serological test for T. gondii infection was performed by latex agglutination test. The seropositive tiger was a 9 years old female tiger which ophthalmic examination also shown a retinal lesion, a spot of hyperreflective area in right fundus of the right eye. T. gondii had been shown to implicate as a major contributor to retinal lesions in felids. Serological evidence and lesion found in the Bengal tiger in this study consistent with T. gondii infection. Hence, it was considered as ...

The dog showed the signs of weakness, emaciation, as well as pale mucus membranes and mild dehydration. Hematological analysis revealed moderate anemia, with 28.7% packed cell volume (normal range 35-55%) and a 4.94 x 10μl erythrocyte count (normal range 5-9 x 10μl). However, hemoparasites and other ectoparasites such as ticks and lice were not found. The finding of this investigation is valuable for control of the fleas in order to prevent adverse effects on animal health.

This study was aimed to update the current status of flying foxis habitats and use as database for epidemiological study in order to prevent their potential zoonoses. From our survey, we found 14 rooting sites including 10 previously reported and 4 newly discovered sites. These new sites were mangrove forest, Muang, Samut Sakorn, Banklong Thonglang, Banglen, Nakhon Pathom, Private area, Hanka, Chainat and Nongseedam Temple, Nongsaeng, Saraburi. Furthermore, it was also found that the distribution of flying fox covered 10 provinces of the central region, composing of Angthong, Suphanburi, Singburi, Ayutthaya, Samut Sakorn, Saraburi, Nakhon Nayok, Chainat, Nakhon Pathom, and Bangkok. Since more rooting sites and higher number of flying fox were discovered as well as their distributing areas has expanded, it was suggested that the overall population of flying ...

The adult flies feed on the blood of mammals and may transmit several parasites and pathogens. We conducted an entomological survey of Stomoxyini flies from different sites in Thailand. Stomoxyini flies were collected at four major types of sites: zoos, livestock farms, wildlife conservation areas and a national park using vavoua traps between November 2010 and April 2011. A total of 3,314 Stomoxyini flies belonging to the genera Stomoxys, Haematobosca, Haematostoma and Haematobia were collected. Eight species were identified: S. calcitrans (46.6%), S. uruma (26.8%), S. pulla (4.3%), S. indicus (0.7%), S. sitiens (0.1%), H. sanguinolenta (11.2 %), H. austeni (0.5%) and H. irritans exigua (9.8%). The diversity of Stomoxyini flies in the livestock farms was higher than the other sites. Altitude correlated with the number of flies. This study provides information that may be us...

Adult females of Tabanus megalops and Tabanus striatus, which are members of the T. striatus complex, are morphologically similar and hence difficult to distinguish using morphological characteristics. In addition, molecular identification by DNA barcoding is also unable to distinguish these species. These two species can occur sympatrically with Tabanus rubidus, which is morphologically similar to T. megalops and T. striatus. Wing geometric morphometrics has been widely used in various insects to distinguish morphologically similar species. This study explored the effectiveness of landmark-based geometrics at distinguishing and identifying T. megalops, T. rubidus, and T. striatus in Thailand. Specimens were collected from different geographical regions of Thailand, and only unambiguously identified specimens were used for geometric morphometric analyses. Left wings of fe...

They are known to cause trypanosomosis or surra in domestic and wild animals in Thailand. This study conducted an entomological survey of horse flies from different sites in Thailand. Horse flies were collected from three different habitats: primary forests, secondary forests and villages using Nzi traps between April 2012 and December 2016. A total of 1835 female horse flies were collected and 45 species were identified. The five most abundant species were T. striatus (25.45%), followed by T. megalops (21.36%), T. rubidus (14.82%), T. tamthaiorum (7.90%) and T. oxybeles (6.38%). The highest proportion of horse flies was collected in villages (39.13%), followed by primary forests (34%) and secondary forests (26.87%). The species diversity of horse flies in primary forests was higher than in other habitats. The results of this study may be used for a horse fly control program.

However, morphological identification of Stomoxyinae flies is difficult, and there is risk of misidentification. Therefore, this study analyzed cytochrome oxidase 1 ( cox 1) barcodes to test their ability to discriminate between taxonomic groups. cox 1 barcodes (657 bp) from 66 specimens were classified into 8 species. cox 1 sequences have typical insect mitochondrial characteristics including a high AT content (mean = 69%), especially at the third codon position. cox 1 barcodes were able to discriminate between species with high interspecific divergence, especially those that are morphologically difficult to distinguish, such as certain Stomoxys species ( S. indicus , S. pullus , and S. uruma ) and Haematobia sub-species ( H. irritans irritans and H. irritans exigua ). Phylogenetic analysis and the genealogical sorting index revealed that all Stomoxyinae species formed a monophyletic group and were clearly separated into distinct clusters based on species. Species delimitation by the Poisson tree processes model indicated previously unrecognized diversity within Stomoxys and Haematobosca . Thus, DNA barcoding was able to discriminate between morphologically uncertain or misidentified Stomoxyinae flies and confirm the correct species, which are important steps for elucidating diversity.

In this study, we used PCR to detect the presence of Babesia bovis, Babesia bigemina, and T. orientalis in 279 beef cattle from Western Thailand and A. marginale in 608 beef cattle from the north, northeastern, and western regions. The PCRs were performed using species-specific primers based on the B. bovis spherical body protein 2 (BboSBP2), B. bigemina rhoptry-associated protein 1a (BbiRAP-1a), T. orientalis major piroplasm surface protein (ToMPSP), and A. marginale major surface protein 4 (AmMSP4) genes. To determine the genetic diversity of the above parasites, amplicons of B. bovis and B. bigemina ITS1-5.8s rRNA gene-ITS2 regions (B. bovis ITS, B. bigemina ITS), ToMPSP, and AmMSP4 genes were sequenced for phylogenetic analysis. PCR results revealed that the prevalence of B. bovis, B. bigemina, T. or...

All 325 samples were found negative in viral detection with molecular technique, cell culture and serological methods. Although this study found no evidence of highly pathogenic avian influenza (HPAI) H5N1 in the area, the monitoring and surveillance for avian influenza should be continuously conducted.

A total of 1,166 individuals belonging to 13 species from 8 genera and 7 families were recorded. Hog-nosed Bat (Craseonycteris thonglongyai), Croslet Horseshoe Bat (Rhinolophus coelophyllus) and Thomas's Horseshoe Bat (Myotis siligorensis) were the three most abundant species captured in the areas. Malayan Slit-faced Bat (Nycteris tragata) is new records for cave in Western Thailand. The bat species diversity in the underground cave was higher than the above ground cave. Results of this study provide information for future management and conservation of bats.
