Description

Technical Field

[0001] The present invention relates to the technical field of application of veterinary chemical pharmaceutical preparations, and more particularly to a pharmaceutical preparation for treating mycoplasma infection in animals and application thereof. Background Art

[0002] Mycoplasma, also known as mycoplasma, is between the size of bacteria and viruses. It is a type of prokaryotic organism with a diameter of about 0.11 μm and only a cell membrane without a cell wall. At present, the mycoplasmas that have a greater impact on poultry farming are mainly Mycoplasma gallisepticum (MG), Mycoplasma synoviae (MS) and Mycoplasma meleagridis (MM). MG is the main cause of respiratory diseases in poultry. MS can cause subclinical respiratory symptoms, arthritis, synovitis, air sac inflammation, genital tract inflammation and egg tip syndrome in poultry. Mycoplasma meleagridis causes embryonic death in turkeys, leading to mild respiratory infections, bone abnormalities and decreased growth rates in turkeys. According to epidemiological surveys, the average positive infection rate of mycoplasma in chicken flocks is 70% to 80%. Chickens of all ages can be infected, and chickens of different breeds have similar resistance. Except for some SPF chicken farms, it can be said that any chicken farm is troubled by mycoplasma infection.

[0003] Mycoplasma is mainly transmitted through the air. Another important transmission method is vertical transmission through breeder chickens, which causes mycoplasma in chicks or makes them weak after hatching. The third transmission method is through certain chicken embryo live vaccines or yolk antibody inactivated vaccines. The chicken embryos or yolks used to make vaccines carry mycoplasma viruses, which cause mycoplasma transmission during vaccination. The disease has a high incidence rate, a long course of disease, and slow recovery. Once the disease appears in a chicken farm, in addition to the harm it causes, it can also induce a variety of viral and bacterial respiratory diseases, making the prevention and control of the disease more complicated. Mycoplasma has no cell wall and is easy to develop drug resistance. General drug treatment is ineffective. Even if effective drugs are used for treatment, it only has a certain effect in the short term and cannot be completely cured. It can relapse after stopping the drug. The widespread prevalence of this disease in my country has caused immeasurable economic losses to the poultry industry and is a potential killer of chicken health. According to statistics, after chickens are infected with Mycoplasma gallisepticum, the egg production rate of laying hens will drop by 20%-40%, the feed conversion rate will decrease by about 21%, the weight of broilers will decrease by about 38%, the carcass quality will also decrease, and the cost of drug use will increase, resulting in serious economic losses and seriously affecting the sustainable development of the poultry industry.

[0004] Aminoglycosides are glycoside antibiotics formed by aminosugar and aminocyclitol connected by oxygen bridges. Commonly used in clinical practice include streptomycin, kanamycin, gentamicin, neomycin, amikacin, gentamicin, spectinomycin, etc. Kanamycin is an aminoglycoside antibiotic produced by Streptomycekanamyceticus. It has a broad antibacterial spectrum and strong bactericidal effect. It has inhibitory effects on both Gram-positive and Gram-negative bacteria and has post-antibiotic effects (PAE) on many pathogenic bacteria. Kanamycin is an inhibitor of protein synthesis. Its main mechanism of action is to hinder the formation of complexes required for protein synthesis in the initial stage of protein synthesis; in the protein formation stage, it interacts with RNA 30S subunits, causing errors in gene coding; in the termination stage of protein synthesis, it inhibits the action of termination factors, so that the synthesized protein cannot be separated from RNA normally. Kanamycin is a commonly used drug in the poultry and livestock farming industry. It is widely used to treat infections caused by various bacteria, such as Escherichia coli, drug-resistant Staphylococcus aureus, cocci, Klebsiella pneumoniae and Shigella dysenteriae. However, in the breeding process, the irregular use of antibiotics leads to increased drug resistance and increased drug dosage, which not only greatly increases the breeding cost, but also poses a hidden danger to food safety. The development of new low-cost solutions is the key to the healthy development of the poultry farming industry.

[0005] Transfer factor (TF) is a type of small molecule dialyzable substance released by immune-active T lymphocytes in white blood cells. TF carries the specific immune information of sensitized lymphocytes and can induce T cells to transform into specific sensitized lymphocytes in the recipient. Therefore, it can specifically and passively transfer the donor's cellular immunity to the recipient, so that the recipient can obtain specific cellular immune function, that is, transfer and expand cellular immunity. TF is a polypeptide substance containing a variety of amino acids, with a small molecular weight, no pyrogen, no antigenicity, no toxic side effects and no species difference. It is a new and safe immune preparation. TF can non-specifically enhance the cellular immune function of the recipient; it can specifically transfer a certain cellular immune function of the donor to the recipient so that it has this cellular immune function; it also has the ability to promote the binding of monocytes to Ig complexes; and it has the function of inducing the release of interferon.

[0006] At present, TF has been successfully used as an adjuvant or applied to the early treatment of viral, parasitic, fungal and bacterial infections, as well as for the treatment of immunodeficiency, tumors, allergies and autoimmune diseases. Animals highly immunized with a certain antigen are used to prepare a large number of specific TFs for the prevention and treatment of infectious diseases, especially viral infectious diseases. It has a rapid effect, significant effect, no drug residue, and no toxic side effects. Specific TF is divided into anti-tumor specific TF, anti-microbial (including virus, bacteria, fungus, etc.) TF and other specific TF. Japan Bio-Health Company immunizes dairy cows with bacterial and viral antigens that cause major infectious diseases in chickens, and prepares specific TF from colostrum, which is used to prevent and treat diseases caused by pathogens such as Staphylococcus aureus, Streptococcus , Clostridium perfringens, Escherichia coli, Pseudomonas aeruginosa, Salmonella, Haemophilus parahaemolyticus, Mycoplasma, Newcastle disease, infectious bronchitis virus (IBV), and avian infectious bursal disease virus (IBDV). The effect is good and the product has been put on the market for a long time.

[0007] The breeding field is in urgent need of a pharmaceutical preparation that can reduce the dosage of antibiotics and improve the therapeutic effect of poultry mycoplasma diseases. The present invention combines aminoglycosamine compounds with transfer factors to treat animal diseases caused by mycoplasma infection, aiming to effectively solve the long-standing problem of mycoplasma infection faced by farmers.

[0078] Example 7 Study on the stability of the pharmaceutical preparation of the present invention

[0079] The stability of active ingredients in medicines is related to clinical effects. Especially under high temperature conditions, active ingredients are easily inactivated. In order to ensure product quality, the stability of drug preparations under high temperature conditions was investigated. The method is: the drug preparations in each example are placed at 60°C for 10 days to investigate the stability of the active ingredients. The specific test results are shown in Table 1:

[0080] Table 1 Drug preparation stability results

[0081]

[0082]

[0083] From the stability results in the above table, it can be seen that the injections prepared according to Examples 1-6, when placed at 60°C for 10 days, have almost no change in the content of aminoglycosamine compounds and transfer factors, and are of stable quality, especially the injection of Example 1 has the best stability. However, for the injection of Comparative Example 1, the transfer factor quality stability is relatively poor under high temperature conditions.

[0084] Example 8 Clinical effect test of the preparation of the present invention

[0085] 180 test chickens were randomly divided into 6 groups, 30 in each group, and weighed separately. The experimental groups and drug treatments are shown in Table 2.

[0086] The tested chickens were inoculated with Mycoplasma gallisepticum synoviae (containing 1×10 9 ccu / ml), the dosage was 0.3mL / bird, and the negative control group (healthy control group) experimental chickens were injected with normal saline in the trachea, the dosage was 0.3mL / bird. Clinical observation was carried out every day after artificial infection, and the mental state, appetite and respiratory status of the chickens were recorded. 24h after inoculation with the standard strain of Mycoplasma gallisepticum synoviae, except for the negative control group, the chickens in other infection groups gradually began to show symptoms such as coughing, panting, mental depression, decreased appetite, rapid breathing, and open mouth breathing.

[0087] At this time, each group of animals was given drugs according to Table 2, and the drugs were given once. After the drugs were given, the clinical reactions of the chickens were observed every day for 14 consecutive days. After the test, each chicken was weighed and dissected, and the macroscopic changes of the air sac and lungs were observed, and the air sac damage was scored. The mortality rate, cure rate, effective rate, relative weight gain rate, and air sac damage reduction rate were calculated.

[0088] Table 2 Experimental groups and treatment methods

[0089]

[0090] The test results are as follows:

[0091] Table 3 Test results

[0092] Group No. mortality rate Cure rate Efficiency Average airbag rating Airbag injury reduction rate Relative weight gain Negative control group 0 / / 0 / / Positive control group 8 / 30 0 / 30 0 / 30 4.58 23.4% 84.2% Test Group A 0 30 / 30 30 / 30 0 100.0% 105.7% Test Group B 7 / 30 5 / 30 15 / 30 2.16 36.0% 90.3% Test Group C 5 / 30 7 / 30 12 / 30 3.72 45.3% 89.1% Test Group D 1 / 30 25 / 30 27 / 30 0.13 96.4% 94.7%

[0093] It can be seen from the above test results that the pharmaceutical preparation prepared according to Example 1 can effectively treat diseases caused by Mycoplasma gallisepticum infection, and the use effect is better than using a single preparation.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
