The occurrence of luteinizing hormone-like molecule and its receptor in the blue swimming crab, Portunus pelagicus.

Knowledge of the neuroendocrine system possibly improves the reproductive performance of captivated crustacean broodstock in aquaculture and it may substitute eyestalk ablation. In this study, we explored the luteinizing hormone (LH)-like molecule and proved the existence of the LH receptor (PpelLHR)-like mRNA in the blue swimming crab, Portunus pelagicus. Using the anti-human LH-β antibody, the immunoreactivities were found in the central nervous system (CNS) and ovary of the crab with the strongest signal in the mature ovary.

Survey of Rickettsia spp. and Orientia tsutsugamushi Pathogens Found in Animal Vectors (Ticks, Fleas, Chiggers) in Bangkaew District, Phatthalung Province, Thailand.

Rickettsial infections (Rickettsioses) are the causes of acute fever found in Thailand. It is classified as acute febrile illnesses transmitted by bloodsucking arthropod vectors (tick, flea, and chigger). This research investigated pathogens of scrub typhus in vectors from Bangkaew District, Phatthalung Province.

Two nematode species from freshwater and marine fishes in Thailand, including Ascarophis scatophagi sp. nov. (Cystidicolidae) from Scatophagus argus (Scatophagidae).

One new and one known species of parasitic nematodes are reported from Thailand for the first time: Falcaustra kaverii (Karve et Naik,1951) (Kathlaniidae) from the intestine of the freshwater fish Poropuntius deauratus (Valenciennes) (Cyprinidae) (new host record) and Ascarophis scatophagi sp. nov. (Cystidicolidae) from the intestine of the marine fish Scatophagus argus (Linnaeus) (Scatophagidae).
