Abstract
Mycotoxins are toxic, fungal secondary metabolites that contaminate agricultural commodities, food, and feed. Among them, T-2, HT-2, and diacetoxyscirpenol (DAS; the major type A trichothecene) are primarily produced from Fusarium species. These mycotoxins exert numerous toxicological effects in animals and humans, such as dermatotoxicity, haematotoxicity, hepatotoxicity, nephrotoxicity, neurotoxicity, and immunotoxicity. In the present study, human Jurkat T cells were used as a model to investigate apoptotic cell death induced by T-2, HT-2, and DAS. The results showed that T-2, HT-2, and DAS decreased cell viability and increased production of Reactive Oxygen Species in a time- and dose-dependency. Based on their IC50 values, they could be ranked in decreasing order of cytotoxicity as T-2 > HT-2 > DAS. All tested mycotoxins caused DNA fragmentation, up-regulated cytochrome C, caspase 3, and caspase 9 mRNA levels, and down-regulated the relative expression of Bcl-2 and caspase 8. The effects of these trichothecenes on apoptosis were determined based on flow cytometry. At the IC50 concentrations, the percentages of apoptotic cells were significantly higher than for the controls. Taken together, these data suggested that T-2, HT-2, and DAS could induce apoptosis through the mitochondrial apoptotic pathway.

Abstract
Trypanosoma evansi is a flagellate protozoan parasite responsible for "surra." To generate T. evansi antigens for serodiagnosis, parasites are generally propagated in laboratory animals before isolation. The alternation of animal models using axenic cultivation systems to produce trypomastigotes of various Trypanosoma species is currently available but has never been applied in Thailand. The isolation protocol for separation of live T. evansi trypomastigotes from animal blood components before in vitro cultivation has not been clearly documented. This study focused on validation of trypomastigote isolation method, in vitro cultivation of T. evansi Thai strains, and its virulence ability in vivo. In this study, two strains of T. evansi collected from Thailand were used. Trypanosoma evansi trypomastigotes were propagated in mice, and three different isolation methods, including: low-speed centrifugation, high-speed centrifugation, and ion exchange chromatography using diethylaminoethyl (DEAE) cellulose (or DE52), were compared. Four solutions of in vitro cultivation media, two different in vitro cultivation containers, and different trypomastigote densities for initiation of in vitro culture were compared. Virulence test using in vitro-adapted parasite for 100 days was conducted in vivo. The results showed that the DE52 isolation method was suitable for separation of live T. evansi trypomastigotes from animal blood components before conducting in vitro cultivation. Trypanosoma evansi Thai strains were successfully cultivated and multiplied in HMI-9 Solution I using 25 cm2 flasks and 12-well plates. The parasite was growing slowly at the initiation of in vitro culture for 15-16 days, and then rapidly increased to 10, 20, 50, 100, and 200 folds, approximately. The doubling times were varied from 11.95 ± 8 h to 41.18 ± 4.29 h in vitro. The maximum densities have reached from 0.14 × 106 to 4.63 × 106 trypomastigotes/ml. Virulence test showed that the in vitro-cultivated T. evansi was virulent in mice. In conclusion, T. evansi Thai strains were successfully isolated and cultivated in vitro for the first time. The isolation and in vitro cultivation protocols were clearly provided. The benefit of using the in vitro cultivation system helps in the production of T. evansi antigen, and replacing the use of experimental animals. It is also useful for the development of diagnostic tests in the future.

Abstract
Trypanosoma theileri is a hemoprotozoan parasite that infects various ruminant species. We investigated the epidemiology of this parasite among cattle and water buffalo populations bred in Sri Lanka, using a diagnostic PCR assay based on the cathepsin L-like protein (CATL) gene. Blood DNA samples sourced from cattle (n=316) and water buffaloes (n=320) bred in different geographical areas of Sri Lanka were PCR screened for T. theileri. Parasite DNA was detected in cattle and water buffaloes alike in all the sampling locations. The overall T. theileri-positive rate was higher in water buffaloes (15.9%) than in cattle (7.6%). Subsequently, PCR amplicons were sequenced and the partial CATL sequences were phylogenetically analyzed. The identity values for the CATL gene were 89.6-99.7% among the cattle-derived sequences, compared with values of 90.7-100% for the buffalo-derived sequences. However, the cattle-derived sequences shared 88.2-100% identity values with those from buffaloes. In the phylogenetic tree, the Sri Lankan CATL gene sequences fell into two major clades (TthI and TthII), both of which contain CATL sequences from several other countries. Although most of the CATL sequences from Sri Lankan cattle and buffaloes clustered independently, two buffalo-derived sequences were observed to be closely related to those of the Sri Lankan cattle. Furthermore, a Sri Lankan buffalo sequence clustered with CATL gene sequences from Brazilian buffalo and Thai cattle. In addition to reporting the first PCR-based survey of T. theileri among Sri Lankan-bred cattle and water buffaloes, the present study found that some of the CATL gene fragments sourced from water buffaloes shared similarity with those determined from cattle in this country.

Abstract
Hemoprotozoan infections often cause serious production losses in livestock. In the
present study, we conducted a PCR-based survey of Babesia bovis,
Babesia bigemina, Theileria annulata,
Theileria orientalis, Trypanosoma evansi and
Trypanosoma theileri, using 423 DNA samples extracted from blood
samples of cattle (n=202), water buffaloes (n=43), sheep (n=51) and goats (n=127) bred in
the Hue and Hanoi provinces of Vietnam. With the exception of T.
annulata and T. evansi, all other
parasite species (B. bovis, B.
bigemina, T. orientalis and
T. theileri) were detected in the cattle populations
with B. bovis being the most common among them.
Additionally, four water buffaloes and a single goat were infected with
B. bovis and B.
bigemina, respectively. The Hue province had more
hemoprotozoan-positive animals than those from the Hanoi region. In the phylogenetic
analyses, B. bovis-MSA-2b, B.
bigemina-AMA-1 and T. theileri-CATL
gene sequences were dispersed across four, one and three different clades in the
respective phylograms. This is the first study in which the presence of
Babesia, Theileria and Trypanosoma
parasites was simultaneously investigated by PCR in Vietnam. The findings suggest that
hemoprotozoan parasites, some of which are genetically diverse, continue to be a threat to
the livestock industry in this country.

Abstract
OBJECTIVE To survey the Angiostrongylus cantonensis (A. cantonensis) or the rat lungworm in a rat, definitive host, and in a giant African land snail (Achatina fulica), the intermediate host, in Phitsanulok, Thailand. METHODS Rats and giant African land snails were captured from Tha Pho sub-district, Phitsanulok, Thailand. Rats were killed and examined for adult A. cantonensis. The artificial digestion method following Baermann technique were used for isolation third stage larvae of A. cantonensis. RESULTS Sixty-two rats were captured and they were identified as Rattus argentiventer, Rattus rattus (R. rattus), Bandicota savilei, and Bandicota indica but only one animal (R. rattus) of 62 rats (1.61%) was positive with adult worm of A. cantonensis. The third stage larvae of A. cantonensis were examined on 307 Angiostrongylus fulica snails. It was found that the overall infection rate was 12.38% (38 infected out of 307 Achatina snails). CONCLUSIONS This study demonstrates that A. cantonensis is available in the natural hosts of Phitsanulok. This suggests that the transmissions of this parasite to human may occur in this region.

Abstract
A swine infected with Trichinella spiralis is a source of transmission to human through consumption of raw or improperly cooked pork. Detection of larvae is suitable for carcasses, so that pigs in households or farms can be examined serologically for trichinellosis. This study compared antigens, crude (CAg), excretory-secretory (ESAg) and surface (SAg), for their potential use in IgG-ELISA. Serum samples were collected from 5 experimentally infected swine with T. spiralis (pTs), 147 positive cases of 9 other parasitic infections, 12 mixed infections of other parasites, and 35 normal controls. At the same 100% sensitivity, specificity of tests was in a range of 98-77%. ESAg was the best source of antigen with specificity of 98.3% at cut-off value of 0.439. False positives included coccidiasis (1/86) and mixed infections (2/39). For CAg, trichuriasis (2/11), coccidiasis (5/86), and mixed infections (8/39) gave cross-reactions and some of these samples had OD values far above cut-off value of 0.332. Cross-reactions of SAg were Oesophagostomum spp-like GI-nematode infection (1/1), unidentified GI-nematode infections (2/3), trichuriasis (5/11), coccidiasis (29/86) and mixed infections (4/39). Thus, ESAg has the highest potential in serodiagnosis, with antibody to T. spiralis in pigs being detected at the earliest 16 day post-infection. However, crude antigen demonstrated a good specificity at 91.8%, and this antigen has a potential to be used as a detection of choice for swine trichinellosis, but the antigen preparation must be improved for higher specificity.
