Isolates from consecutive Clostridium difficile infection (CDI) fecal samples underwent multilocus sequence typing. Potential reinfections with different genotypes were identified in 88/560 (16%) sample pairs taken 1 to 1,414 days (median, 24; interquartile range [IQR], 1 to 52 days) apart; odds of reinfection increased by 58% for every doubling of time between samples. Of 109 sample pairs take...

background: babesia ovis and theileria ovis are among the important and main etiological agents causing ovine babesiosis and ovine theileriosis, causing severe economic losses among sheep and goats. the aim of the present study was to determine the prevalence and molecular diagnosis of b. ovis and t. ovis in lohi sheep at livestock experiment station bahadurnagar, okara, pakistan. methods: the ...

OBJECTIVE To assess the prevalence of TT virus (TMV) infection in a series of patients with chronic hepatitis C virus (HCV) infection, with or without benign (mixed cryoglobulinemia) or malignant (B-cell non-Hodgkin lymphoma (B-NHL)) lymphoproliferative disease. METHODS Sixty-six HCV patients were studied, including patients with mixed cryoglobulinemia (n=30), B-NHL (n=15), and no mixed cryog...

in order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of eimeria (e. acervulina, e. maxima, e. necatrix, and e. tenella) at 26 days of age. there was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. histopathological examinat...

INTRODUCTION Severe malaria due to P. vivax infection is increasingly observed now a days. Organ failure in vivax malaria is caused by mechanisms of inflammation as well as sequestration. In this study we have compared the complications in vivax malaria with those in falciparum or mixed malaria. AIMS AND OBJECTIVES 1) To study various complications in adult inpatients of vivax malaria. 2) To ...

Studying drug resistance in Plasmodium falciparum requires accurate measurement of parasite response to a drug. Factors such as mixed infection of drug-resistant and -sensitive parasites can influence drug test outcome. Polymorphic DNA sequences are frequently used to detect mixed infections; infections with a single genotype or having a minor allele smaller than a subjectively selected cut-off...
