[ 1 ] - Monitoring the prevalence of the tetracycline efflux genes among E. coli isolated from chicken colibacillosis
BACKGROUND: Avian Colibacillosis can lead to important economic losses in the poultry industry. Escherichia coli the causative agent of this disease has acquired resistance to different antibiotics, including tetracycline. OBJECTIVES: This study was carried out to detect the distribution of tetracycline Group І efflux genes genes among E.coli isolates from from avian colibacillosis in Iran by P...
[ 2 ] - Use of immunogenic moiety of Pseudomonas aeruginosa exotoxin A as a DNA vaccine in experimentally contaminated mice
Background: DNA immunization is an appropriate method to produce an immunological response. Pseudomonas aeruginosa produces exotoxin A which is highly cytotoxic for eukaryotic cells. Since domains II (translocation domain) and 1b of the toxin have antigenic qualities, so they could be useful candidates to protect against pseudomonas infections. Objectives: To evaluate if recombinant plasmid co...
[ 3 ] - A comparative study on the effects of different cryoprotectants on the quality of canine sperm during vitrification process
Cryopreservation has the capacity to extend spermatozoa’s lifespan and viability. In addition, the semen samples can be collected, preserved and stored or sent to distant locations and still be used long after the death of the semen donor. In this study for the vitrification of dog sperm (fresh and swum-up sperm), different cryopreservation mediums on the basis of glycerol, milk and egg yolk we...
[ 4 ] - Molecular Detection of Antibiotic Resistance Determinants in Lactobacillus Bacteria Isolated from Human Dental Plaques
Introduction: Dental caries is a significant public health problem which destroys the calcified tissues of the teeth. The frequency of lactobacilli in dental caries is usually high. The objective of this study was to evaluate the incidence of these bacteria in dental caries and to identify the antibiotic resistance patterns of them. Methods: Specimens from dental plaque were collected from 30 p...
