Species of Garra (Cyprinidae: Labeoninae) in the Salween River basin with description of an enigmatic new species from the Ataran River drainage of Thailand and Myanmar.

Garra panitvongi, new species, is described from the Ataran River drainage, Salween River basin, of southeastern Myanmar and western Thailand. It is the sixth species of Garra known from the Salween River basin and is readily distinguished from all congeners by the red-orange color of the body and caudal fin, and a pointed proboscis with a blue stripe on each side from the anterior margin of the orbit to the tip of the proboscis and with the stripes forming a V-shape. Garra panitvongi is known in the aquarium trade as the Redtail Garra. Descriptive information is provided on poorly known species of Garra in the Salween River basin, and Garra nujiangensis is transferred to Ageneiogarra.

Acupuncture Improves Heart Rate Variability, Oxidative Stress Level, Exercise Tolerance, and Quality of Life in Tracheal Collapse Dogs.

Among the respiratory disorders in dogs from small breeds, tracheal collapse is one of the most commonly found in clinical practice. Presently, acupuncture is widely used as an alternative treatment which was shown to bring about positive effects in the treatment of human respiratory diseases. The present study demonstrated the effect of acupuncture on tracheal collapse dogs. We hypothesized that acupuncture can help dogs suffering from tracheal collapse by improving various parameters including heart rate variability, serum biomarkers for oxidative stress, exercise performance, and quality of life. Twenty client-owned dogs from small breeds with tracheal collapse disease were enrolled. The study was divided into two 5-week periods. During the first period, the dogs received normal veterinary care but received no acupuncture treatment (NAC). After completing that period, all forms of treatment were withheld for one week before the beginning of the second period. In the second period, all dogs restarted normal veterinary care and underwent acupuncture treatment (AC) once a week for five consecutive weeks. Blood was collected at the beginning and end of each of the two periods for malondialdehyde (MDA) level measurement. Heart rate variability (HRV) was recorded at the 1st, 3rd and 5th weeks of both periods. Exercise tests were performed at the beginning and end of AC period and questionnaire interviews with the owners were accomplished at the end of each period. The results showed that acupuncture can alleviate clinical signs of tracheal collapse, reduce MDA level, and improve sympathovagal balance. We suggest that acupuncture treatment could be used as an adjunct treatment for canine tracheal collapse.

ASIAN ELEPHANT (ELEPHAS MAXIMUS) SUFFERING FROM LIGHTNING STRIKE SUCCESSFULLY TREATED BY INTEGRATIVE VETERINARY MEDICINE.

A captive female Asian elephant (Elephas maximus), approximately 30 yr old, was struck by lightning and displayed obtundation, dysphagia, drooling, and muscle weakness. A physical examination, hematologic test, blood gas analysis, and electrocardiogram were performed. Treatments included the administration of mannitol, dexamethasone, antibiotics, analgesics, vitamins, and intravenous fluid. Conventional therapy resulted in improvement but not complete resolution of clinical signs. Therefore, acupuncture was integrated into the treatment protocol. Electroacupuncture and laser acupuncture were administered every other day; aqua acupuncture was administered once a week. No complications were observed during acupuncture treatment. Acupuncture, a form of traditional Chinese veterinary medicine (TCVM), contributed to the resolution of clinical signs in this case and may be an effective adjunctive treatment for other neurologic disorders in elephants.

Proinflammatory cytokines and lipopolysaccharides up regulate MMP-3 and MMP-13 production in Asian elephant (Elephas maximus) chondrocytes: attenuation by anti-arthritic agents.

BACKGROUND: Osteoarthritis (OA), the most common form of arthritic disease, results from destruction of joint cartilage and underlying bone. It affects animals, including Asian elephants (Elephas maximus) in captivity, leading to joint pain and lameness. However, publications regarding OA pathogenesis in this animal are still limited. Therefore, this study aimed to investigate the effect of proinflammatory cytokines, including interleukin-1 beta (IL-1ß), IL-17A, tumor necrosis factor-alpha (TNF-α), and oncostatin M (OSM), known mediators of OA pathogenesis, and lipopolysaccharides on the expression of cartilaginous degrading enzymes, matrix metalloproteinase (MMP)-3 and MMP-13, in elephant articular chondrocytes (ELACs) cultures. Anti-arthritic drugs and the active compounds of herbal plants were tested for their potential attenuation against overproduction of these enzymes. RESULTS: Among the used cytokines, OSM showed the highest activation of MMP3 and MMP13 expression, especially when combined with IL-1ß. The combination of IL-1ß and OSM was found to activate phosphorylation of the mitogen-activated protein kinase (MAPK) pathway in ELACs. Lipopolysaccharides or cytokine-induced expressions were suppressed by pharmacologic agents used to treat OA, including dexamethasone, indomethacin, etoricoxib, and diacerein, and by three natural compounds, sesamin, andrographolide, and vanillylacetone. CONCLUSIONS: Our results revealed the cellular mechanisms underlying OA in elephant chondrocytes, which is triggered by proinflammatory cytokines or lipopolysaccharides and suppressed by common pharmacological or natural medications used to treat human OA. These results provide a more basic understanding of the pathogenesis of elephant OA, which could be useful for adequate medical treatment of OA in this animal.

Revision of the horseface loaches (Cobitidae, Acantopsis), with descriptions of three new species from Southeast Asia.

Acantopsis (Cobitidae) is revised based on analysis of morphological and molecular data. Four of the six available names, A. dialuzona, A. spectabilis, A. octoactinotos, and A. thiemmedhi, are valid, and three new species, A. rungthipae, A. dinema, and A. ioa, are described. All species are described morphologically, distributions are mapped, and relationships are discussed for those for which molecular data (CO1, RAG1) are available. Labial barbels, color pattern, and meristic counts are the most diagnostic features. Although the long snout of Acantopsis is perhaps the most emblematic attribute of the genus, its relative length increases with growth, reducing its taxonomic value. Species can be difficult to identify on the basis of color pattern alone, as habitat and preservation methods appear to strongly influence the color pattern. Despite interspecific overlap of some highly variable traits, each species has a unique set of morphological characteristics that remain observable even when the color pattern is obscured, and some species are restricted to single drainages, greatly simplifying identification. The phylogenetic analyses revealed high molecular divergence between even the most morphologically similar species, with mean uncorrected CO1 p-distances between species ranging from 12.1-15.4%. Species of Acantopsis exhibit significant genetic structuring consistent with recognized freshwater ecoregions. Acanthopsis lachnostoma Rutter 1897, from Swatow, China, is not assignable to Acantopsis.

GENETIC AND IMMUNOLOGICAL EVIDENCES OF BORRELIA BURGDORFERI IN DOG IN THAILAND.

Lyme disease is a tick-borne zoonotic disease caused by spirochete Borrelia burgdorferi. It is transmitted from animals to humans by the bite of infected ticks of the genus Ixodes. Although Lyme disease has been reported in China and Japan, the disease has never been reported in Thailand. Blood samples and ticks were collected from 402 dogs from 7 and 3 animal clinics in Chiang Mai and Phuket Provinces, Thailand, respectively. Blood samples were tested for antibodies against B. burgdorferi, Anaplasma spp, Ehrlichia spp and Dirofilaria immitis using a commercial kit, and positive blood samples were subjected to nested PCR assay for B. burgdorferi fla, ospA and ospC, amplicons of which also were sequenced. Only one dog (from Chiang Mai) was positive for B. burgdorferi, with 97% to 100% genetic identity, depending on the sequences used for comparison, with strains from United State of America. All 376 ticks collected were Rhipicephalus sanguineus, but no tick was found on the infected dog. Further investigations of the infection source and vector are needed to understand potential risks of Lyme disease to dogs and humans in Thailand.

Comparison of the Effect of Two Purification Methods on the Immunogenicity of Recombinant Outer Membrane Protein H of Pasteurella multocida Serovar A:1.

Recombinant outer membrane protein H (rOmpH) of Pasteurella multocida strain X-73 can be purified using affinity chromatography but this adversely affects its immunogenicity. The current study presents the results from an intervention study comparing the immunogenicity of rOmpH purified using electroelution with rOmpH purified using affinity chromatography and native OmpH purified using electroelution and a nonimmunized control group. Chickens immunized with rOmpH purified using electroelution produced the highest ELISA antibody levels against P. multocida strains. Chickens in each of the 5 treatment groups were split into two subgroups for challenge with two different P. multocida strains. The average number of adhesions to CEF cells was statistically significantly lower in sera from chickens immunized with rOmpH or native OmpH purified using electroelution than in those of the three other treatment groups. The survival amongst chickens immunized with rOmpH or native OmpH purified using electroelution indicated high levels of protection. In contrast, survival probability was zero or low in the groups immunized with rOmpH purified using affinity chromatography and in the nonimmunized group. These findings show that the rOmpH purified using electroelution retains its immunogenicity and stimulates high levels of protection in chickens against P. multocida infection.

Aperioptus pictorius Richardson 1848 is a senior synonym of Acanthopsoides molobrion Siebert 1991, and Aperioptus is a senior synonym of Acanthopsoides Fowler 1934 (Cypriniformes: Cobitidae).

Aperioptus pictorius was described by Richardson in 1848 with limited textual information but with an illustration sufficient to confirm the species as one currently recognized as Acanthopsoides molobrion making Aperioptus a senior synonym of Acanthopsoides Fowler 1934 and A. pictorius a senior synonym of Acanthopsoides molobrion Siebert 1991. Species to be recognized in Aperioptus in addition to A. molobrion are A. gracilis (Fowler 1934), A. gracilentus (Smith 1945), A. delphax (Siebert 1991), A. hapalias (Siebert 1991), and A. robertsi (Siebert 1991). Aperioptus also is a senior synonym of Neacanthopsis Smith 1945, type species Neacanthopsis gracilentus.

A revision of the spirit loaches, genus Lepidocephalus (Cypriniformes, Cobitidae).

Lepidocephalus has been assumed to include only two species and confined to peninsular Malaysia and Indonesia. However, based on records and collections reported herein, the genus contains five species and is most common in the Chao Phraya basin of Thailand. Large rivers seem to be the preferred habitat, and difficulty in collecting these rivers may account for the paucity of specimens in collections. The known range of these five species includes western and southern Borneo, Java, Sumatra, peninsular Malaysia, and central Thailand.
