- چکیده انگلیسی: After sudden death with a history of about two weeks ruminal tympany, a 3-year-old, male alpaca from Huantaiqi Zoo, Chongqing, China was presented to the Animal Diseases Rapid Diagnosis Center, Southwest University, Chongqing, China for diagnosis of the death causes. At necropsy, the primary pathological lesions were found in the lung. A pronounced hemorrhage with topical congestion and lobular pneumonia was identified. Sero-fibrinogenous pleural effusion was also detected in the thoracic cavity. After necropsy, the lung sample was processed for histological examination, while lung, hydropericardium, and heart-blood samples were processed for bacteriological examination. From the lung tissue, abundant fluid exudate was found in the pulmonary alveoli. Meanwhile, a mild to moderate hemorrhage and inflammatory cells infiltrations were also observed in the lung sections. Pure isolates on the 5.00% defibrinated sheep blood agar were submitted for identification by morphological and molecular methods. Sequencing results indicated that the Gram-negative sporadic bacilli were all belonged to Morganella morganii. To the best of our knowledge, this is the first record of M. morganii induced pneumonia in an alpaca.

- چکیده:
- چکیده انگلیسی: Duck beak atrophy and dwarfism syndrome (BADS) is a newly emerged disease in China since 2015. In October 2017, an unidentified disease occurred in Cherry Valley ducks, Chongqing municipality, the southwest of China. The affected birds showed short beak and growth retardation clinical signs. The disease caused approximately 20.00% morbidity and serious weight loss due to retarded growth. In order to identify the causative agent of BADS, liver, spleen, lung and heart samples were collected for virus isolation, hemagglutination test, PCR identification, and partial gene sequencing. The isolated virus was tentatively named SC16. Hemagglutination test indicated that the virus was negative to chicken red blood cells. Based on the PCR and sequencing results, the causative agent of BADS was a novel duck-origin goose parvovirus (DGPV) while no another co-infection pathogen was found in this case. Further analysis could provide insights into the control strategies of DGPV in ducks.

- چکیده انگلیسی: Background: The reason for the high incidence of gastric cancer (GC) in Xianyou County of China was largely
unknown. We aimed to explore the potential sociodemographic risk factors and their associations to GC. Methods:
A population-based case-control study was conducted during March 2013 and April 2016 in Xianyou County. All
newly diagnosed patients of GC were recruited as cases, while controls were selected by matching for cases’ sex, age
(± 3 years) and the place of residence. Results: A total of 523 GC cases and 523 matched healthy controls were included
in the final analysis with mean age of 66.27±8.81 years for cases and 66.31±8.83 years for controls, respectively.
Participants with low socioeconomic status were observed with higher GC risk compared to those in high socioeconomic
status (adjusted OR=2.10, 95% CI: 1.13-3.89). Compared to those regularly drink green tea, patients did not have this
dietary habit had nearly 3-fold increased GC risk (adjusted OR=2.91, 95% CI: 1.38-6.13). Other dietary habit, including
consumption of hard food, omission of breakfast, consumption of pickled vegetables 30 years ago, overeating were all
associated with increased risk of GC. Interaction effect were found. Patients in low socioeconomic status and skipped
breakfast had 10-fold higher risk of GC compared to reference group in high socioeconomic status and eat breakfast
regularly (OR=10.71, 95% CI: 5.19-22.10). Furthermore, patients in low socioeconomic status and consumed pickled
vegetable 30 years ago had 6-fold higher risk of GC compared to those in high socioeconomic status but did not intake
pickled vegetables 30 years ago (OR=6.11, 95% CI: 3.87-9.66). Conclusion: High incidence of GC risk in Xianyou
County might be partly attributed to various sociodemographic factors. Specific prevention effort could be target on
population in low socioeconomic status combined with habit of breakfast omission or intake of pickled vegetables.- انتشار مقاله: 10-04-1397
