 หัวเรื่อง:การศึกษาเชื้อไวรัสในปลาน้ำจืดที่เกิดโรคระบาดด้วยกล้องจุลทรรศน์อิเล็คตรอน ผู้เขียน: ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์ , นายกิติ ศรีสุภาพ, รองศาสตราจารย์,  Churee Pankamnerd, นายบุญธรรม จงเจริญ, รองศาสตราจารย์, Ong-ard Lawhavinij, Chantana Kunjara สื่อสิ่งพิมพ์:pdf Abstract Eighteen fresh water fish affected with ulcerative skin disease outbreak in years 1983-1984 from the fish farms and natural canals in Supanburi and Nakhon Pathom provinces were examined for virus particle by using transmission electron microscope. There was no virus particle observed in the ulcerative tissue from eight fish collected, a few different types of virus particles, however, were found in the live cells and one type in the splenic cells. These viral particles may be grouped into two groups according to their different sizes. The first group was a large spherical particles of 45-90 nm. having capsid surrounding the nucleic acid core. The other group was a small virus particles of 10-30 nm. with nonenveloped spherical or icosahedral shaped particles and were crystallized arrays of irregular arrays in cytoplasm or cytoplasmic membrane-bound inclusion body. The groups of virus particles were revealed much morphological similar to Reoviruses in the former and Picornaviruses in the later which are both RNA viruses. This study could not concluded that the virus particles observed were the causative agent of the ulcerative skin disease outbreak of fresh water fish. Further study on their significance in such disease outbreak in being conducted. |

หัวเรื่อง:พยาธิภายในที่พบในทางเดินอาหารของไก่พื้นเมืองโตเต็มวัยในภาคใต้ของประเทศไทย ผู้เขียน:Chantana Kunjara Na Ayudhya, Arkom Sangvaranonda สื่อสิ่งพิมพ์:pdf Abstract The 350 adult native chickens from 34 amphoes of 14 provinces in the southern part of Thailand were examined by post mortem for collection the internal parasites from digestive tracts including bursa, trachea and oviduct for prognosis of the health of the native chickens in backyard. The result revealed that from 350 chickens, 293 (83.71%) infested with endoparasites, 249 (71.14%) tapeworms which were most infested, 237 (67.67%) with roundworms, 2(0.57%) thorny head worms and 3 (0.86%) Eimeria tenella. The percentage of roundworms infestions were of the followings : 8.29% Ascaridia galli, 14.57% Capillaria contorta and C. annulata, 16.57% Tetrameres americana, 33.71% Heterakis gallinarum, 0.29% Dispharynx spiralis, (0.29%) 8.0% Cheilospirara hamulosa and 31.71% Gongylonema inglovicula. The percentage of tapeworm infections were of the followings : 62.00% Raillietina echinobothrida, 18.29% R. tetragona, 3.43% R. cesticillu, 14.57% Hymenolepis, 4.29% Amoebotaenia and 0.29% Davainia proglottina. Cheilospirura hamulasa and thorny head worm from the native chickens in the southern part of Thailand were also reported. |

Results revealed prevalence of The following endoparasites; Prosthogonimus spp. (0.3%), Hymenolepis spp. (0.6%), Raillietina spp. (14.7%), Ascaridia galli (15.8%), Heterakis gallinarum (3.4%), Acuaria spp. (3.7%), Oxyspirura mansoni (11.3%), Capillaria spp. (9.9%) and unsporulated oocysts of coccidian parasite (10.7%). |

In addition, specific organs on hosts and infestation characters of these internal parasites were also reported in this study. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Study on Salmonella Carrier Rate in Native Chickens) ผู้เขียน:Chantana Kunjara, Srismai Kupooan, นายกิติ ศรีสุภาพ, รองศาสตราจารย์, ดร.ธานีรัตน์ สานติวัตร, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractStudies on the prevalence of Salmonella in native chickens were conducted. Samples included visceral and feces were collected and examined for Salmonella spp. By cultured on specific selective and indicative media for this organism. Four of all 599 (0.67%) of chickens under studied were positive for Salmonella spp. And were futher biochemical and serological differentiated in to 3 species included S. pullorum, S. havana, and S. Stanley. The former two serotypes were shown to be more resistant to various commonly used drugs than the third one. Experimental infection of the three Salmonella spp. Isolated in native chickens resulted in some deaths in group of S. pullorum inoculated chickens and typical white lesions were revealed on cardiac muscle and liver of died chickens. Salmonella of the same species were frequently isolated daily from feces collected from live chickens for at least 30 days after infection. The low carrier rate of Salmonella obtained from this study might not indicate extensive spread in native chickens. However , attention should be paid on this infection due to its easy transmit and long term being as carrier after recoverd from infection. |
