RESUMEN
Objective To investigate the seroprevalence of Toxoplasma gondii infections among patients with rheumatoid arthritis, malignant tumors and schizophrenia in Wuxi City, so as to provide data support for the control of toxoplasmosis in these patients. Methods A total of 205 cases with definitive diagnosis of rheumatoid arthritis, 257 cases with definitive diagnosis of malignant tumors and 235 cases with definitive diagnosis of schizophrenia were recruited, while 250 healthy volunteers served as controls. The demographic features were captured from the study subjects and serum samples were collected. The serum IgG and IgM antibodies against T. gondii were detected using an enzyme-linked immunosorbent assay (ELISA) in all study subjects, and the positive rates of anti-T. gondii IgG and IgM antibodies were compared between the patients and controls. Results The seroprevalence of the anti-T. gondii IgG antibody was 20.98%, 24.12% and 24.68% in patients with rheumatoid arthritis, malignant tumors and schizophrenia, which were all significantly greater than in healthy controls (χ2 = 31.54, 42.12 and 42.98, all P values < 0.01), and the seroprevalence of the anti - T. gondii IgM antibody was 1.46%, 2.72% and 1.70% among patients with rheumatoid arthritis, malignant tumors and schizophrenia, which were all significantly higher than in healthy controls (χ2 = 0.06, 1.52 and 0.21, all P values > 0.05). Conclusions The patients with rheumatoid arthritis, malignant tumors and schizophrenia present with higher seroprevalence of the anti-T. gondii IgG antibody than healthy controls in Wuxi regions. Screening of T. gondii infections among the patients with rheumatoid arthritis, malignant tumors and schizophrenia should be intensified to prevent the damages caused by T. gondii infections.

RESUMEN
Members of genus Acanthamoeba are widely distributed in the environment. Some are pathogenic and cause keratitis and fatal granulomatous amoebic encephalitis. In this study, we isolated an Acanthamoeba CJW/W1 strain from tap water in Wuxi, Jiangsu Province, China. Its 18S rDNA was sequenced and a phylogenetic tree was constructed. The isolated cysts belonged to morphologic group II. Comparison of 18S rDNA sequences of CJW/W1 strain and other isolates showed high similarity (99.7%) to a clinical isolate Asp, KA/E28. A phylogeny analysis confirmed this isolate belonged to the pathogenic genotype T4, the most common strain associated with Acanthamoeba-related diseases. This is the first report of an Acanthamoeba strain isolated from tap water in Wuxi, China. Acanthamoeba could be a public health threat to the contact lens wearers and, therefore, its prevalence should be monitored.

RESUMEN
Objective To establish a risk assessing indicator system after the transmission interruption of schistosomiasis in Wuxi City,so as to provide evidences for formulating strategies on schistosomiasis control and prevention. Methods A primary risk assessing indicator system was established based on the literature review. Alternative indicators were scored and screened to establish a final indicator system through two rounds of Delphy method and the related normalized weights and combined weights were also calculated. Results The risk assessing indicator system was established through two rounds of expert consultation in-cluding 3 first grade indicators and 15 second grade indicators. Among the first grade indicators,the normalized weights of natu-ral environment,key populations and social environment were 0.3706,0.2929 and 0.3365,respectively. Among the second grade indicators,the migrant population accounted for the highest combined weight of 0.1252 compared to domestic animal of 0.0371. The authority degree among the first grade indicators was between 0.91 and 0.93,while the authority degree among the second grade indicators was between 0.79 and 0.92. Conclusion The scientific and authoritative risk assessing indicator sys-tem after the transmission interruption of schistosomiasis is established,which provides the evidences for risk assessment on schistosomiasis transmission in Wuxi City.
RESUMEN
Objective To investigate the prevalence and risk factors of Toxoplasma gondii infection among key populations in Wuxi City,Jiangsu Province,so as to provide evidences for developing preventive and control interventions for T. gondii in-fection. Methods A questionnaire was designed to conduct face-to-face interviews to HIV/AIDS carriers/patients,tumor pa-tients,pregnant women and pet breeders. The blood samples were collected to test anti-Toxoplasma IgM and IgG antibodies by using ELISA method. Results Totally 404 participants were investigated,and 38 were positive in testing T. gondii antibodies (9.4%),and among these,37(97.4%)were IgG positive and 1(2.6%)was IgM positive. The multivariate logistic regression indicated that age,regularly contacting cats/dogs and being HIV positive were associated with the infection of T. gondii(OR=2.1,2.6 and 2.3,all P < 0.05). Breeding pets,being HIV positive and being tumor patients were more likely to infect T. gondii than being pregnant(OR = 1.5,8.1 and 2.8,all P < 0.05). Conclusion The high infection rate of T. gondii is observed among key populations in Wuxi City,so that the effective measurements should be taken to enhance the intervention among key popula-tions including immunocompromised people,pet breeders or people having bad dietary habits of eating raw food.

RESUMEN
Objective To understand the epidemiological characteristics of malaria in Wuxi City,and explore effective strat?egies and measures for malaria elimination. Methods The data on malaria cases in Wuxi from 2005 to 2014 were collected and analyzed. Results In Wuxi City,from 2005 to 2014,201 malaria cases were reported,of which,there were 52 local cases and 149 imported cases. Totally 156 malaria cases were reported from 2005 to 2009,of which 6 cases were infected with Plasmodi?um falciparum,and 45 malaria cases were reported from 2010 to 2014,of which 23 cases were infected with P. falciparum. From 2005 to 2009,the ratio of male to female was 2.39:1. Migrant workers,farmers and workers were the major infected popu?lations,with a proportion of 41.03%,17.95% and 9.62%,respectively. From 2010 to 2014,the ratio of male to female was 10.25:1. Workers,farmers and migrant workers were the major infected populations,with a proportion of 37.78%,11.11%and 6.67%,respectively. The peak of malaria incidence was observed from May to October. From 2005 to 2009,most cases were re?ported by CDCs,and from 2010 to 2014,most cases were reported by medical institution. There was an increase in proportion of P. falciparum. Conclusion The control and prevention of malaria should focus on imported cases in the future in Wuxi. The doctors should improve the capacity of malaria diagnosis and treatment.
RESUMEN
Objective To investigate the prevalence of Toxoplasma gondii infection and awareness of toxoplasmosis?related knowledge among women with poor pregnant outcomes in Wuxi City. Methods A total of 217 women with poor pregnant out?comes from Wuxi City during the period of January 2011 to December 2015 were randomly selected as the study subjects( a study group),while 250 women with normal pregnancy were served as controls(a control group). The sero?prevalence of T. gon?dii infection was detected by using ELISA and compared between the study and control groups. The awareness of toxoplasmosis?related knowledge was investigated by using a self?designed questionnaire and compared between the study and control groups. Results The positive rate of anti?Toxoplasma antibody was 30.88%in the study group,which was significantly higher than that (8.8%)in the control group(χ2 =36.7,P0.05). Conclusions This study demonstrates higher prevalence of T. gondii infection in women with poor pregnant out?comes than in those with normal pregnancy in Wuxi City. Considering the harm of T. gondii infection during pregnancy and the low awareness of toxoplasmosis?related knowledge in pregnant women,the health education of toxoplasmosis?related knowledge should be strengthened,especially for pregnant women,so as to reduce the prevalence of T. gondii infection among pregnant women to improve the better child?bearing and rearing level.
