Background and Aims: Inhibition of viral growth in coinfected cells with two different viruses has been described. This phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. In this study we superinfected reovirus infected HeLa cells with poliovirus to determine if poliovirus can replicate in s...

  Introduction : The decreased level of immunity in Human Immunodeficiency Virus (HIV) infected patients increases their vulnerability to various opportunistic fungal infections. Oral candidiasis has been found to be the most common fungal infection among HIV infected patients. The present study was conducted to evaluate the spectrum of various opportunistic fungal infections and their correlat...

conclusions these findings suggest that nmr-based urinary metabonomics approach might be a useful tool for the clinical diagnosis of depression in hbv-infected patients and the six potential biomarkers could be helpful for developing an objective diagnostic method. limited by the number of recruited subjects, future studies are required to validate our conclusions. patients and methods in this ...

background: haemobartonella (also known as mycoplasma) is a blood organism of cats and can cause many anemia and many clinical signs in the infected cats. objectives: the purpose of the present study is to calculate the incidence rate of haemobartonellosis in pet cats of tehran and study its relationship with certain factors. moreover, some blood parameters in the infected cats were compared wi...

mixed infection of plants with more than one virus results in different types of interactions. interaction between two recently identified lettuce infecting viruses in iran, lettuce x potexvirus (levx) and rubus chlorotic mottle sobemovirus (rucmv), was studied on co-infected chenopodium murale and chenopodium quinoa plants. plants were mechanically inoculated with either levx, rucmv or both. c...

The genus Aeromonas is a group of bacteria that widely distributed in water bodies and belongs to the normal intestinal microbiota aquatic terrestrial animals. In present work, rainbow trout fingerlings were experimentally infected by an immersion bath with different species. Subsequently, behavior groups was observed recorded. Infected evaluated histopathology. highest percentages hyperpigment...
