破伤风是由破伤风杆菌引起的一种非接触性急性传染病。破伤风杆菌广泛存在于土壤和粪便中,当它侵入伤口时可以在伤口的脓血和坏死组织中发芽繁殖并产生强烈的破伤风毒素,导致神经中毒和毒血症。马属动物较易患此病,常因外伤、去势、分娩等因素而感染。潜伏期一般为1~3周,在今年3月份笔者遇到1例马破伤风病例,经过治疗后痊愈。  相似文献

破伤风是人和动物都容易感染的一种疾病,它主要是由于破伤风梭菌引起伤口感染,而且一般情况是伤口较深并且很脏,没有及时清洗伤口,破伤风梭菌乘虚而入,这种疾病没有季节性,一年中每天都可能发生。破伤风梭菌是一种厌氧菌,他在很多地方都普遍存在,像泥土,大粪,甚至尘埃中也会存在本梭菌,它感染家畜后死亡率很高。对破伤风梭菌的治疗方法也有很多,像提前将这种病的疫苗给家畜注射,这样即使家畜受到外伤也不用担心本病的发生,也会给养殖业带来利益。另外,要及时清理家畜的伤口或是手术等留下的深伤口防止这种梭菌感染家畜。本文就家畜破伤风的治疗简单谈谈,希望能对畜牧业家畜治疗本病上有帮助。  相似文献

Tetanus toxoid (TT) was assessed as a positive marker for avian influenza (AI) virus vaccination in chickens, in a vaccination and challenge study. Chickens were vaccinated twice with inactivated AI H5N2 virus vaccine, and then challenged three weeks later with highly pathogenic AI H5N1 virus. Vaccinated chickens were compared with other groups that were either sham-vaccinated or vaccinated with virus with the TT marker. All sham-vaccinated chickens died by 36 hours postinfection, whereas all vaccinated chickens, with or without the TT marker, were protected from morbidity and mortality following exposure to the challenge virus. Serological testing for H5-specific antibodies identified anamnestic responses to H5 in some of the vaccinated birds, indicating active virus infection.  相似文献

For lack of relevant data of the literature, the tetanus immunisation results obtained in the two sexes were compared in an animal model. Complete immunisation series of weaned, adult and aged guinea-pigs (20-25 animals/group) were performed with aluminium phosphate (AlPO4) adsorbed purified tetanus toxoid (PTAP) as well as with typhoid-tetanus vaccine (TY-TE) containing lipopolysaccharide (LPS). Both vaccines contained 5.0 Lf (limes flocculans, Ramon) per single dose of tetanus toxoid, purity degree: 1500 Lf/mg protein nitrogen (PN). Tetanus antitoxin titres (TAT) were measured after the first shot, and subsequently before and after booster. Compared to TAT of male animals, significantly lower titres were found in female animals after basic immunisation with PTAP in all the three age groups: 1.03 vs. 0.57, 8.75 vs. 5.64, and 0.27 vs. 0.15 IU (international units, related to the Copenhagen International Standard) per ml (sex-chromosome-dependent differences?), as well as in adult animals immunised with TY-TE, before booster: 0.07 vs. 0.02 IU/ml (hormone-dependent differences?). In the latter case the TAT results after booster were 14.49 vs. 12.89 IU/ml. Thus, the lower female prebooster titres were counterbalanced by a quick and effective increase of titres following booster. These results are in accordance with our previous observations in humans (Réthy and Réthy, 1986). From our observations with tetanus immunisation series on guinea-pigs it can be concluded that TAT may be influenced by the effects of sex chromosomes as well as of sexual hormones. During active anti-tetanus immunisation with LPS-containing vaccine (TY-TE) the lower adult female prebooster titres are presumably counterbalanced by the better functionality of the female immune memory.  相似文献

Although a T-dependent antibody response (TDAR) assay is generally recommended as the first-line immune function assay in nonclinical immunotoxicity evaluation, second-line assays such as delayed-type hypersensitivity (DTH) to measure cell-mediated responses can provide helpful additional information. In this study, male Cynomolgus monkeys were injected intramuscularly either once or twice with 1 mg Keyhole Limpet Hemocyanin (KLH) or twice with a commercially available tetanus vaccine (40 IU tetanus toxoid + 0.06 mg aluminum hydroxide). All animals were subsequently challenged by intradermal injections of the same antigen or aluminum hydroxide after 4, 6 and 8 weeks. Clinical reactions at the injection sites were scored 24, 48 and 72 h post challenge. Skin biopsies were taken on completion of the observation period after each challenge for standard histological examination and immunolabeling using CD3 (T lymphocytes), CD19 (B lymphocytes) and CD68 (macrophages) antibodies. Tetanus toxoid induced stronger clinical reactions than KLH, whereas aluminum hydroxide induced no clinical reaction. Perivascular mononuclear cell infiltrates, a histopathological finding consistent with a DTH reaction, were seen after all challenges with tetanus toxoid or KLH, but not with aluminum hydroxide. Immunohistochemistry evidenced the presence of T lymphocytes and macrophages within these infiltrates. These results suggest that tetanus toxoid adjuvanted with aluminum hydroxide can induce a consistent DTH response for use as a model of cell-mediated response in Cynomolgus monkeys.  相似文献

Influenza and tetanus-specific antibodies of the IgG sub-isotypes are posively transferred to foals via colostrum and inhibit their response to inactivated influenza vaccines and tetanus toxoid. High titres of influenza antibodies of IgGa and IgGb subisotypes and tetanus antibodies of the IgGa, IgGb and IgG(T) subisotypes were detected in postsucking serum samples collected from foals born to mares that had received booster doses of multicomponent vaccines during the last 2 months of gestation. Thereafter, titres declined in an exponential manner but were still detectable in all foals at age 26 weeks, regardless of whether they had been vaccinated prior to age 26 weeks. Mean +/- s.e. half-life of decline of influenza IgGa antibodies (27.0 +/- 2.3 days) was significantly shorter than that of influenza IgGb antibodies (39.1 +/- 2.7 days; P<0.005). Tetanus IgGa and IgGb antibodies declined with half-lives of 28.8 +/- 3.0 and 34.8 +/- 5.1 days, respectively. Titres of tetanus IgG(T) antibodies were substantially higher than those of influenza IgG(T) antibodies in postsucking samples and remained so through age 26 weeks, declining with a half-life of approximately 35 days. Postsucking titres of tetanus and influenza antibodies of the IgA isotype were low and declined rapidly to undetectable levels. Yearlings showed significant increases in titre of influenza IgGa, IgGb and IgG(T) subisotype antibodies but no increase in influenza IgA antibodies in response to 2 doses of multicomponent vaccines containing tetanus toxoid and inactivated influenza A-1 and A-2 antigens. Yearlings also showed strong tetanus IgGa, IgGb and IgG(T) subisotype responses to one dose of vaccine and a substantial further rise in titre in response to administration of a second dose 3 weeks later, but failed to show an increase in titre of tetanus IgA antibodies. The influenza and tetanus IgGa, IgGb and IgG(T) subisotype responses of 6-month-old foals to vaccination followed the same pattern as those shown by yearlings but titres were generally lower. In contrast, 3-month-old foals failed to show increases in titre of either influenza or tetanus IgG subisotypes in response to 2 doses of vaccine and generally needed 1-3 additional booster doses of vaccine to achieve titres similar to those achieved by yearlings after 2 doses. Based on the finding that maternal antibodies exert a significant inhibitory effect on the response of foals to tetanus toxoid and inactivated influenza antigens, it is recommended that primary immunisation of foals born to vaccinated mares should not commence before age 6 months.  相似文献

Tetanus is rare in cats owing to their innate resistance. Clinical diagnosis may not be obvious in the early stages of the disease when characteristic signs of generalised tetanus are absent. However, the history of a penetrating/neglected wound and the presence of persistent involuntary muscle rigidity in a mentally alert animal should always lead to the suspicion of tetanus. Prompt diagnosis and treatment are the keys to a successful outcome.  相似文献

A four-month-old male, entire, border collie was presented to the Queen Mother Hospital for Animals with a two day history of muscular spasms and "Risus sardonicus". Tetanus was diagnosed, and the dog was treated with tetanus antitoxin, antibiotics and supportive therapy. Coxofemoral luxation resulted as a complication of the tetanus and was successfully managed by performing a femoral head and neck excision. This is the first report of joint luxation associated with Clostridium tetani infection in a dog.  相似文献

Bradycardia, sinus arrest, and second-degree atrioventricular block developed in 2 dogs with tetanus. Clinical signs attributable to bradycardia were not apparent. Administration of atropine resulted in resolution of the arrhythmias. Both dogs responded well to supportive treatment; the bradycardia resolved within 4 days of onset without specific treatment. Tetanus should be included in the differential diagnosis when increased neuromuscular excitability and bradycardia are evident, as is found in toxicity with acetylcholinesterase inhibitors, increased intracranial pressure, and other neurologic disorders.  相似文献

Insect bite hypersensitivity (IBH) is an IgE-mediated dermatitis caused by bites of midges from the genus Culicoides. We have shown previously that peripheral blood mononuclear cells (PBMC) from IBH-affected horses produce higher levels of IL-4 and lower levels of IL-10 and TGF-β1 than those from healthy horses, suggesting that IBH is associated with a reduced regulatory immune response. FoxP3 is a crucial marker of regulatory T cells (Tregs). Here we have determined the proportion of CD4(+)CD25(+)FoxP3(+) T cells by flow cytometry in PBMC directly after isolation or after stimulation with Culicoides extract or a control antigen (Tetanus Toxoid). There were no differences between healthy and IBH horses either in the proportion of FoxP3(+)CD4(+)CD25(+) cells in freshly isolated PBMC or in the following stimulation with Tetanus Toxoid. However, upon stimulation of PBMC with the allergen, expression of FoxP3 by CD4(+)CD25(+high) and CD4(+)CD25(+dim) cells was significantly higher in healthy than in IBH horses. Addition of recombinant IL-4 to PBMC from healthy horses stimulated with the allergen significantly decreased the proportion of FoxP3 expressing cells within CD4(+)CD25(+high). These results suggest that IBH is associated with a decreased number of allergen-induced Tregs. This could be a consequence of the increased IL-4 production by PBMC of IBH-affected horses.  相似文献
