To investigate the genes involved in
-induced cytoplasmic incompatibility among three natural populations of
in eastern China, so as to provide insights into the development of preventive and control measures for mosquito-borne diseases based on
.

The cytoplasmic incompatibility was tested among three natural populations of
collected from Nanjing and Wuxi of Jiangsu Province and Tangkou of Shandong Province using reciprocal crosses.
a infection was detected in
using a PCR assay, and the expression of
and
genes was quantified using a fluorescent quantitative real-time PCR (qPCR) assay.

Bidirectional compatibility was found between the natural populations of
collected from Nanjing and Wuxi of Jiangsu Province (
= 0.57 and 0.15, both
values > 0.05), while bidirectional incompatibility was seen between the natural populations of
collected from Tangkou of Shandong Province and Wuxi of Jiangsu Province (
= 63.81 and 43.51, both
values < 0.01), and between the natural Tangkou of Shandong Province, and
gene may be involved in the
-induced cytoplasmic incompatibility among three natural populations of
.
Different Wolbachia numbers are detected in natural populations of C. pipiens pallens collected from Nanjing and Wuxi of Jiangsu Province and Tangkou of Shandong Province, and WD0513 gene may be involved in the Wolbachia-induced cytoplasmic incompatibility among three natural populations of C. pipiens pallens.
To investigate the implementation of schistosomiasis control activities in China during the coronavirus disease 2019 (COVID-19) epidemic, so as to evaluate the impact of COVID-19 epidemic on the national schistosomiasis control program in China.

On April 2020, 3 counties (districts) were randomly selected from each of the 12 schistosomiasis-endemic provinces (municipality, autonomous region), and a questionnaire survey was conducted to investigate the implementation of schistosomiasis control activities in these counties (districts) from January to March 2020. Then, the impact of the COVID-19 epidemics on the national schistosomiasis control program of China was evaluated using a comparative analysis approach.

Among the 36 counties (cities, districts) sampled from 12 provinces (municipality, autonomous region), 66.67% were at a high and medium risk of COVID-19 epidemics. The implementation of schistosomiasis control activities assignment, human schistosomiasis examination and treatment, snail control wi China. Policy and financial support should be strengthened to ensure the completion of the schistosomiasis control program.
To investigate the distribution of
snails in Four-Lake Basin of Hubei Province, so as to provide scientific evidence for the development of snail control interventions.

The snail distribution was surveyed by means of the retrospective study and cross-sectional survey in the Four-Lake Basin in Spring of 2016. The data pertaining to the endemic situation of schistosomiasis were collected and analyzed in the Four-Lake Basin from 2008 to 2018, and the associations of snail habitat areas with the prevalence of
in humans and bovines were examined.

There were 16 003 snail habitats in the 9 schistosomiasis-endemic counties (districts) in the Four-Lake Basin in 2016, covering an area of 246 million m
. The mean density of living snails was 0.622 5 snails/0.1 m
, which was relatively high in weed-type settings (0.688 0 snails/0.1 m
) and ditches (0.706 4 snails/0.1 m
). Type I (current snail habitats, 53.03%) and Ⅱ- Ⅳ (historical snail habitats, 46.97%) settings were predominant snail habitats. A big change was seen in snail habitats in dry farmland, marshland and paddy farmland, and environmental modification resulted in satisfactory snail control effectiveness. Selleckchem SP2509 In addition, the area of snail habitats positively correlated with the changes in the prevalence of
infections in humans (
= 0.842,
< 0.01) and livestock (
= 0.695,
< 0.01).

The integrate strategy with an emphasis on the control of the source of
infections results in remarkable snail control effectiveness in the Four-Lake Basin; however, there is a risk of re-emerging snail habitats.

To investigate the current prevalence of human intestinal protozoal infections in Tibet Autonomous Region, so as to provide the scientific basis for the development of the future control strategy.

The study sites were sampled using a stratified cluster random sampling method in different ecological zones and different geographical locations of Tibet Autonomous Region in 2015. Fecal samples were collected from the permanent residents at ages of 3 years and older for the detection of intestinal protozoa cysts and trophozoites. The region-, gender-, age-, occupation- and education level-specific prevalence of human intestinal protozoal infections was estimated and compared.

A total of 70 study sites were sampled from 23 counties (districts) in 3 ecological zones of Tibet Autonomous Region in 2015. Among 17 939 subjects surveyed, there were 1 117 residents infected with intestinal protozoa, with a prevalence of 6.23%. There were 9 species of intestinal protozoa identified, and
(3.59%),
(0.74%) and
s (
2 = 14.659,
< 0.01), and a higher prevalence was seen in farmers (7.17%) and herdsmen (5.28%), and in residents with a primary school education (6.62% and illiterate resi- dents (6.33%).

The prevalence of human intestinal protozoal infections remains high in Tibet Autonomous Region. The health education pertaining to intestinal parasitic disease control requires to be intensified among farmers and herds- men in rural areas.
