Seroprevalence of Dirofilaria immitis in Cats from Liaoning Province, Northeastern China
Honglie Hou,Lili Cao,Wenzhi Ren,Dansheng Wang,He Ding,Juan You,Xinhua Yao,Hang Dong,Yanbing Guo,Shuxian Yuan,Xi-Chen Zhang,Pengtao Gong 대한기생충학ㆍ열대의학회 2017 The Korean Journal of Parasitology Vol.55 No.6
The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P<0.01). There was no significant difference between males and females (4.7% vs 4.2%, P>0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats (<3 years old) in feral populations (16.8 vs 2.4%, P<0.01), while the difference between the age groups was not statistically significant in domestic cats (2.4% vs 0.51%, P>0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

We report a simple and green method for fabricating SnS2 modified moss composites for removal of heavy metal (Cr(VI)) considering the fact that the issue of wastewater caused by the discharge of heavy metal is becoming increasingly serious. More importantly, this kind of functional materials that are capable of removing effectively Cr(VI) from wastewater for water purification is quite few on the market. Hence, in the paper, such SnS2 decorated moss photocatalysts for removal of heavy metal (Cr(VI)) were designed and prepared via a simple and green method: chemical bath reaction. The as-designed materials (C@SnS2) integrate the independent properties of moss (with excellent performance in absorption of heavy metal) and SnS2 (with good photocatalytic reduction of Cr(VI) under visible light irradiation), showing a faster photocatalytic rate than those independent components. The experiment results indicate that more than 98.5% of Cr(VI) was reduced under visible light irradiation for 70 min, while only 18.2% and 84.4% of Cr(VI) were removed in the presence of C-moss and pure SnS2 at the same condition, respectively. Furthermore, the as-designed C@SnS2 has good recyclability in the removal of Cr(VI). We believe such simple and green method to prepare photocatalyst for wastewater treatment with excellent performance will provide a good platform to design new photocatalytic materials for water purification.
