| In a taxonomic study of yeasts that have been isolated in French Guiana and Thailand, five yeast strains isolated from plants were found to belong to the Yamadazyma clade of Saccharomycotina. On the basis of morphology, physiology and the nucleotide divergence in the D1/D2 domain of the 26S nuclear ribosomal RNA (nrRNA) gene, as well as the internal transcribed spacers (ITS) domain of the nrRNA gene operon, these strains were identified to represent three novel species in this teleomorphic clade. An additional isolate, that is publicly available from the CBS yeast collection and isolated from Taiwan, was found to be similar to one of the novel species described from Thailand. Yeast species belonging to the Yamadazyma clade have previously been described as... |

| Babesia bovis, an intraerythrocytic protozoan parasite, causes severe clinical disease in cattle worldwide. The genetic diversity of parasite antigens often results in different immune profiles in infected animals, hindering efforts to develop immune control methodologies against the B. bovis infection. In this study, we analyzed the genetic diversity of the merozoite surface antigen-1 (msa-1) gene using 162 B. bovis-positive blood DNA samples sourced from cattle populations reared in different geographical regions of Thailand. The identity scores shared among 93 msa-1 gene sequences isolated by PCR amplification were 43.5-100%, and the similarity values among the translated amino acid sequences were 42.8-100%. Of 23 total clades detected in our... |

| In the present study, we screened blood DNA samples obtained from cattle bred in Brazil (n=164) and Ghana (n=80) for Babesia bovis using a diagnostic PCR assay and found prevalences of 14.6% and 46.3%, respectively. Subsequently, the genetic diversity of B. bovis in Thailand, Brazil and Ghana was analyzed, based on the DNA sequence of merozoite surface antigen-1 (MSA-1). In Thailand, MSA-1 sequences were relatively conserved and found in a single clade of the phylogram, while Brazilian MSA-1 sequences showed high genetic diversity and were dispersed across three different clades. In contrast, the sequences from Ghanaian samples were detected in two different clades, one of which contained only a single Ghanaian sequence. The identities among the MSA-1... |

| Plasmodium gallinaceum and Plasmodium juxtanucleare are the most common species of Plasmodium causing avian malaria in domestic and wild chickens. In Thailand, P. gallinaceum infection in poultry has been reported since 1996, but P. juxtanucleare infection has never been reported. The objective of this study was to identify and characterize the Plasmodium species infecting Burmese red junglefowls (Gallus gallus spadiceus) in Thailand using molecular techniques. Seventeen Burmese red junglefowls from a farm in western Thailand were suspected of being infected with blood parasite. Blood samples of all seventeen Burmese red junglefowls were collected and examined. Microscopic examination revealed the presence of Plasmodium trophozoites in 5 out of 17 samples.... |

| Thailand is a developing nation dependent on agriculture. Due to lack of modern public health practices, she suffers from the consequences of foodborne illnesses. The number of foodborne infection cases has nearly doubled in the past 10 years. Salmonella and Campylobacter pose the greatest risk of bacterial contaminants, mostly from pigs and chickens, and this paper will review livestock production systems and foodborne diseases from cases stemming from these sources. Due to the complexity of the livestock production systems, collection of data to date has been sporadic, but it is clear that controls are needed in slaughterhouse processing methods, and more communication between agencies and surrounding regions is paramount for proper surveillance to have... |

| Babesia ovata is a tick-transmitted hemoprotozoan parasite that infects cattle. In our study, bovine blood samples (n=2,034) were collected from 10 different countries (Brazil, China, Ghana, Japan, Mongolia, the Philippines, South Africa, Sri Lanka, Thailand and Vietnam) and DNA extracted. The DNA samples were screened using an established and specific polymerase chain reaction (PCR) assay targeting the Apical membrane antigen 1 (AMA-1) gene. Parasite DNA was detected among samples collected from Japan, Mongolia and Thailand. Sequence analyses confirmed that the PCR assay detected only B. ovata AMA-1, and that amplicons from different geographical locations were conserved. Our findings highlight the importance of designing adequate strategies to control B.... |

| Gastrointestinal zoonotic helminths of dogs and cats have a public health concern worldwide. We investigated the prevalence of gastrointestinal helminths of zoonotic significance in dogs and cats in lower Northern Thailand and utilized molecular tools for species identification of hookworms and Opisthorchis viverrini. Fecal samples of 197 dogs and 180 cats were collected. Overall prevalence of infection using microscopy was 40.1% in dogs and 33.9% in cats. Helminth infection found in both dogs and cats included hookworms, Spirometra spp., Taenia spp., Toxocara spp., 0. viverrini, Strongyloides spp. and Trichuris spp. Hookworms were the most common helminth in dogs, while Spirometra spp. were the most prevalent in cats. Among hookworm infection in dogs and... |

| This study describes the variations in total lipid, lipid classes and fatty acids in the midgut gland (MG), ovary, and muscle tissue of wild-caught <i>Macrobrachium rosenbergii</i> to elucidate the importance of these components during sexual maturation. Mature females were captured in the Mae Klong River, Thailand, from July to September 1998, and divided into five groups according to their ovarian development. Total lipid levels in the ovary increased with maturation, but no concomitant decrease in MG lipids was observed. Thus, the lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves. Higher proportions of neutral lipids (NL), mainly triacylglycerols (TG),... |

| The effects of increasing levels of dietary phospholipids (PL) on the reproductive performance, egg and larval quality, and lipid composition of females of the freshwater prawn <i>Macrobrachium rosenbergii</i> were investigated. Three isolipidic diets containing similar amounts of highly unsaturated fatty acids but varying levels of PL (0.8, 2.4 and 4.6%) were fed during 180 days to three groups of eight females originating from Thai ponds. No significant differences were observed for fecundity, egg size and hatchability, starved larvae size, and size, survival and tolerance to stress of 8 day-old larvae. Similarly, no major differences in the lipid composition of the midgut gland, ovaries and muscle tissue of females could be detected. Results... |

| Shrimp farming in Thailand has had disastrous effects on the environment in the past, which has prompted a government ban on shrimp production in inland areas. However, a new low-salinity shrimp farming system has developed that seems to have fewer disease and environmental problems than previous systems but competes with rice production for land and water resources. The present study found that shrimp farming exhibits increasing returns to scale and is much more profitable than rice farming, which offers opportunities for rice farmers to improve their incomes through diversification. No evidence was found for external environmental effects of shrimp production on rice production or vice versa. A total ban on shrimp production in rice farming areas... |

| In many developing countries the composition of rural households is influenced by the migration of adult household members to urban locations in search of employment. Children may be left in the care of their mother alone, or in the care of grandparents when both parents have migrated. Using representative data from rural Northeast Thailand, this paper investigates whether household composition has any effect on the nutritional outcomes of children. Our findings suggest that household types other than nuclear families result in some significantly worse child nutritional outcomes. One implication is that governments should target programs to protect the welfare of the children of migrants in origin communities. |
