Avian strains of Escherichia coli (213) were subjected to in vitro antibiotic sensitivity tests with twenty-four different chemotherapeutic agents. Chlorhexidine, polymyxin B, colistin, and nitrofurazone exhibited the greatest inhibitory activities against these strains. Various potencies of antibiotics were compared. The activity of sulfachloropyridazine on various types of media failed to sho...

A parasitologic survey of human parasitic infections was made in Shizuoka Prefecture, Japan, during August and September, 1950 (Ritchie et al., 1951a). The objectives included a determination of (i) the incidence of infections, (ii) helminth densities,(iii) factors predisposing infections,(iv) the status of schistosomiasis,(v) status of paragonimiasis and filariasis, and (vi) the efficiency of ...

For the laboratory diagnosis of Chagas disease several tests are commonly used. Sensitivity and specificity must always be taken into account, as well as the fact that these methods vary when we are dealing with an acute or chronic stage of the parasitosis. Also, it is important to remember that the initial stage of Trypanosoma cruzi infection is characterized by the presence of the parasite in...

Parasitic diseases are among the most important infectious diseases and pose health problems in many countries, most especially in developing countries. Workers at food centers could transmit parasitic infections in the absence of sanitation. This is a descriptive study conducted to determine the prevalence of intestinal parasitic infections in food clerks in the city of Tabriz in 2014. Data wa...

Despite recent advancements in predicting the response of shallow strip foundations during earthquake-induced liquefaction, significant modelling–related uncertainties remain, which are focus this paper. The problem is analysed through coupled hydromechanical analyses, employing an advanced constitutive model. model calibrated based only on initial void ratio, and then validated against 6 centr...

malaria is a major problem in tropical and sub-tropical countries, with high morbidity and mortality. splenectomy makes patients more susceptible to serious bacterial and parasitic infections. we report for the first time in iran a fatal case of plasmodium vivax malaria, confirmed by microscopic and molecu­lar (semi-nested multiplex pcr) tests in a patient who had undergone splenectomy due to h...

Strongyloides venezuelensis is a parasitic nematode of rodents frequently used to obtain heterologous antigens for the immunological diagnosis of human strongyloidiasis. The aim of this study was to evaluate membrane fractions from S. venezuelensis for human strongyloidiasis immunodiagnosis. Soluble and membrane fractions were obtained in phosphate saline (SS and SM) and Tris-HCl (TS and TM) fr...

It is common in population screening surveys or in the investigation of new diagnostic tests to have results from one or more tests investigating the same condition or disease, none of which can be considered a gold standard. For example, two methods often used in population-based surveys for estimating the prevalence of a parasitic or other infection are stool examinations and serologic testin...
