abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
ABSTRACT Background and Objective: Lactic acid bacteria are Gram-positive, catalase-negative, nonsporulating, either rod- or coccus-shaped bacteria that have beneficial effects on their hosts by producing antimicrobial substances such as lactic acid, hydrogen peroxide, bacteriocins and biosurfactants. Bacteriocins are antimicrobial peptides that a...
Backgrounds: Due to their antibacterial effects, herbal remedies have an important role in the treatment of infections; particularly in infected wounds. Increased bacterial resistance to antibiotics combined with increased side effects related to their administration has led many researchers to investigate alternative herbal treatments in recent years. In line with this trend, the objective of ...
Background and Objectives: Bioprotective starters, especially lactic acid bacteria, are used in fermentation and biological preservation of the meat products and considered as appropriate substitutes for the chemical preservatives. The aim of this study was to use Lactobacillus plantarum and Pediococcus acidilactici as bioprotective cultures and probiotics for the growth control of important fo...
background: chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. biological control agents are favorable due to their safety for animals and environment. entomopathogenic fungi such as beauveria bassiana are well known for controlling ticks. in this study, two iranian indigenous strains of b. bassiana ( b. bassiana 519...
new approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. in the present study, in vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. the isolated bacteria identified on the basis of their biochemical properties and se...
ABSTRACT Background and Objective: Although antibiotics are commonly used for treatment of infectious diseases, these treatments are often associated with several problems such as unwanted side effects and resistance to antibiotics. The aim of this study was to evaluate the antibacterial effect of aqueous and alcoholic extracts of Nasturtium...
In vitro studies with Trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. Microscopic observations showed that T. harzianm and T. viride, isolated from soil samples from Ahwaz and Karaj, adversely affected the myce...
In another review of the literature on the helminth parasites of camels, El Bihari (71) gave a list of species encountered frequently and their pathogenic effects, together with a list of those encountered occasionally. We are aware of 30 species not men tioned by this author , who provided no information on the geographical distribution of species. It is our purpose here to present a more com...
