Using bacterial preparations of pasteurellosis infection
The using of antibiotics and antimicrobials drugs without control may leads to the development of numerous complications and resistance of microorganisms to antibiotics. The using of antibiotics and antimicrobials drugs should are controlled on farms. That is why the monitoring and determination of sensitivity of bacterial diseases agents to antimicrobial drugs are very important. Results of pasterella, of salmonellas’ and kolibakterias’ monitoring in farms of Azerbaijan are introduced in the article. The studies were conducted on the basis of the department for quality control of biological preparations of the Azerbaijan Scientific Research Institute. Sampling for microbiological studies was carried out on farms from pathological material and premises where livestock of different age groups are kept. At the same time, the spread of the disease, incidence, mortality, mortality, age-related features, economic losses caused by bacterial pathogens were taken into account. Inoculations from samples of bone, brain, heart, liver, spleen, and lymph nodes were performed on simple and selective and differential diagnostic nutrient media. The results were read visually. Antibiotic sensitivity was determined by agar disco-diffusion method. Microbiological monitoring of a number of farms in Azerbaijan has shown that agents of bacterial diseases’ are widely spread. Between the isolated pasterella agent largest number were accounted for Salmonella (54.1%) and the Escherichia (30.8 per cent). The rest (15.1%) were isolated cultures of Proteus, Pseudomonas, Klebsiella, Salmonella, Campylobacteria, Enterobacteria, and Clostridia Citrobacter. This indicates that systematic control over the availability of the causative agents of bacterial infections in all critical points of farms is very necessary. Among isolates that were isolated from ill calves and objects, differences in their sensitivity to antimicrobial agents from active substances that officially have registered in our country were discovered. Bactericidal activity of relatively isolated cultures was showed by oxitetraciklin, colistin, ftorfenicol, zeftiocur, doxicyclin, enroxil and sarafloxacin.
