Intensified aquaculture includes the use of antimicrobials for disease control. In contrast to the situation in livestock, Escherichia coli and enterococci are not part of the normal gastrointestinal flora of fish and shrimp and therefore not suitable indicators of antimicrobial resistance in seafood. In this study, the diversity and phenotypic characteristics of the bacterial flora in raw froz...
materials and methods one hundred ssis specimens were obtained by needle aspiration from purulent material in depth of infected site. these specimens were cultured and incubated in both aerobic and anaerobic condition. for detection of antibiotic susceptibility pattern in aerobic and anaerobic bacteria, we used disk diffusion, agar dilution, and e-test methods. results a total of 194 bacterial ...
the purpose of this research was to study the antimicrobial activities of the endophytic fungi from sesbania grandiflora (l.) pers. the endophytic fungi were isolated from branches and leaves of sesbania grandiflora (l.) pers., and sixty nine isolates were obtained. all isolates were screened for antibacterial and antifungal activities. the indicator organisms were 4 bacteria including staphylo...
In order to study the bacterial flora of dead-in-shell ostrich chicks, twelve unhatched eggs which did nothave external pipping during the hatching period were transferred to the laboratory of microbiology. The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...
The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. I...
3450 bovine from different breeds and ages were clinically examined for the presence of arthritis. 120 cases showed macroscopic evidences of arthritis. mycoplasma spp were isolated from synovial fluid of 21 affected animals. in addition to mycoplasma spp. arcanobacterium pyogenes and staphylococcus epidermidis were isolated from 2 cases. the synovial fluid was markedly increased, straw color, t...
Mastitis, inflammation of the mammary gland, is one of the most costly and complex diseases of the dairy industry. The economic consequences of bovine mastitis are related to treatment, production losses, culling and changes in milk quality. These factors have a substantial impact on the farm business. The complexity is reflected in the numerous causative pathogens, the variety and magnitude of...
Abstract. Ribosomal DNA (rDNA) sequences are widely used for phylogenetic and bacterial identification. However, rDNA of different species often reveals similar or identical same sequences. This study employed the bacterial stable small RNA (ssrA) gene encoding transfer-messenger RNA (tmRNA) as a tool for identification of Staphylococcus aureus, Enterococcus spp, Pseudomonas spp and Enterobacte...
