THERAPY FOR ESCHERICHIOSIS OF NEWBORN CALVES
Description
Blood samples were taken from newborn calves and sent to the Rostov regional veterinary laboratory. The result of the general analysis of blood showed increased erythrocytes, increased red blood cell count and increasing white blood cell count as well as low hemoglobin levels. The results of the studies on the content of phosphorus, calcium, zinc, vitamins A and C in the blood showed that the sick calves have hyperphosphatemia, namely violations of the phosphorus-calcium ratio. A decrease in vitamin A in sick calves to 8.2±0.5 mcg% and zinc to 74.1±1.2 mcg% was found .This indicates a violation of mineral metabolism, which occurs due to a lack of minerals in the diet, but also with intensive withdrawal from the body, as a result of poor absorption and impaired renal filtration. As a result of typing on O-antigen, using a set of polyvalent and serogroup agglutinating O-coliseums, the presence of an adhesive A20 antigen was revealed. In the course of research, faeces from 9 newborn calves of 1-8 days of age were sent to determine the sensitivity to antibacterial drugs. Thus, 9 samples of cultures of E. coli sensitive to the following antibiotics: enrofloxacin, imipenem, meropenem, levofloxacin, and vancomycin, gentamicin, cefotaxime, and rofloxacin. Based on data from blood tests and sensitivity to anti-biotics, the animals were divided into 3 groups. And each group used three different treatment regimens. Observing the calves of the experimental groups, we found that the condition of the sick animals stabilized within 2-4 days. In the first group of 12 calves, 1 calf fell and 11 survived. In the second group of 11 calves, all survived. In the third control group of 12 calves, 7 fell, and 5 survived. When determining the sensitivity of Escherichia cultures isolated from calves of this farm to antibiotics, 100% sensitivity to levomycetin sodium succinate was obtained

Description
We took 20 samples of centralized water for bacteriological studies at two farms of the collective farm “Limann” and the collective farm “50 years of the name of the October Revolution” of the Neklinovsky District of the Russian Federation and sent to the Rostov Regional Veterinary Laboratory. Thus, according to the results of laboratory studies of water, it was found that in the first farm in 7 samples out of 10 under No. 1, 2, 4, 5, 8, 9, 10, common coliform bacteria were found (the number of bacteria in 100 ml according to MUK 4.2. 1018-01), as well as thermo-tolerant coliform bacteria (the number of bacteria per 100 ml according to MUK 4.2.1018-01), in the second farm in 5 samples out of 10 under No. 3, 4, 5, 7, 8 common coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01), as well as thermo-tolerant coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01). According to the results of studies using the rapid test "Biocontrol" revealed that in the first farm in 2 samples out of 10 under No. 4.9 per 1 ml of bacteria 105, which indicates water pollution, and in 5 out of 10 samples No. 1, 2, 5, 8, 10 per 1 ml of bacteria 107, which indicates a strong pollution of water and is the basis for the prohibition of watering animals. In the second household, in 3 samples out of 10 under No. 4, 5, 8 per 1 ml of bacteria 105, which indicates water pollution, and in 2 out of 10 samples No. 3, 7 per 1 ml of bacteria 107, which indicates severe water pollution which is not recommended for animals. Thus, the studied water samples by the bacteriological method coincide with the “Biocontrol” rapid tests, which makes it possible to practically use it in farms
