RESUMO
INTRODUCTION: Toxoplasmosis is a zoonosis caused by Toxoplasma gondii. This study investigated the prevalence and factors associated with toxoplasmosis among pregnant women. METHODS: We followed an analytical observational study. From July 2016 to June 2017, 218 pregnant women were selected. The infection was detected through serological dosage of anti-T.gondii Immunoglobulin(Ig) M and IgG antibodies. RESULTS: The seroprevalence was 35.8%; the factors associated with infection were consumption of non-drinking water, residence in an urban area, and threatened abortion during the current pregnancy. CONCLUSIONS: The seroprevalence of toxoplasmosis among pregnant women is high. The risk factors are dependent on environmental determinants.

OBJECTIVE: To describe the frequency and antiparasitic in vitro susceptibility of Blastocystis hominis in patients admitted to theHospital Regional Lambayeque, Peru. MATERIAL AND METHODS: A cross-sectional study was conducted from January to August 2015 at 313 patients of all ages. B. hominis detection was performed on serial fecal samples by direct microscopic examination and microculture in modified Locke solution. The in vitro susceptibility testing against the drug metronidazole, nitazoxanide, trimethoprim-sulfamethoxazole and erythromycin was performed in 24 strains of B. hominis, which grew up (microculture method) in 10 double concentrations of each antimicrobial (from 256 ug/ml to 0.5 ug/mL) plus a control. RESULTS: 46.3% (145/313) of the sample had B. hominis, also the age between 12 to 17 years and 60 years was associated with higher frequency of parasites (OR: 2.93 and 2.62). The minimum inhibitory concentration (MIC) 90 of metronidazole and nitazoxanide was 3.19 ug/mL and 11.19 ug/ml, respectively, whereas the MIC 90 of trimethoprim-sulfamethoxazole and erythromycin were above 256 ug/mL. CONCLUSIONS: B. hominis occurs in high frequency in patients admitted to the Hospital Regional in Lambayeque, proving to be an important problem of public health in the region. Also B. hominis isolated from these patients were shown to be susceptible in vitro to low concentrations of metronidazole and nitazoxanide so they could be chosen for treatment of this parasite.
