Using of chemical compounds that improve the mucosal immune response to IB vaccine can increase resistance against the virus. To examine the effect of Bromhexine on the mucosal immune response against IB vaccine, 360 one-day broiler chicks were allocated to eight groups, randomly. Group one was the control group with no vaccine so that the group only used Bromhexine. Groups 2, 3, and 4 received IB vaccine for once, twice, and three times at the age of 5, 15, and 25 days, respectively. These groups received Bromhexine from 48 hrs before the vaccination to 24 hrs after receiving the vaccine in drinking water. Group five was the negative control group and did not receive Bromhexine and IB vaccine. Sampling in group five was at the age of 15 days. Groups six, seven, and eight were the main treatment control groups and received IB vaccine at the age of 5, 15, and 25 days without Bromhexine. The chickens were slaughtered 10 days after the vaccination and nose and trachea samples were collected and the mucus surface of respiratory was rinsed. Afterwards, specific immunoglobin A (IgA) level against IB vaccine in the respiratory mucus was measured through ELISA using chicken IgA specific antiglobulin. The results showed that the use of Bromhexine on the first vaccination had no effect on mucosal immune response. However, with the second and third vaccinations, antibody titter to IB vaccine was higher than chickens received vaccine without Bromhexin. It appears that using Bromhexine in booster IB vaccination can improve specific mucosal immune response.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139613125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This disease causes significant economic losses worldwide. Many countries have implemented control programs to eradicate the disease. Such programs face great challenges due to the nature of the pathogen itself, the immune response, the method of pathogen shedding in susceptible animals, and the absence of accurate diagnostic tools, efficient vaccines, and curative medication. However, some control programs succeeded in eradicating the disease, others were less effective and achieved less success. The present review discusses the elements required in disease control protocols and highlights the importance of disease elimination. These control strategies include optimum application of management measures and proper use of combined diagnostic techniques to accurately identify MAP infected animals with high sensitivity and specificity. Nanotechnology has shown promising results in the diagnosis and control of paratuberculosis. All available vaccines do not completely protect the population, but they actually reduce the clinical signs, pathogen shedding and provoke cellular and humoral immune responses. Although the test and slaughter policy of paratuberculosis is considered an effective way for its control, several obstacles hinder its application.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139612431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Positive staining for vimentin and SMA is consistent with myofibroblast reactivity and reflects a continuous inflammatory response seen in feline injection-site sarcomas. Feline injection-site sarcomas are the most serious adverse effect following injection of the vaccine or some other pharmaceutical substances and should be considered in the differential diagnosis of skin swelling in injection sites in the Felidae family.

The animal material of the study consisted of 40 heads of Awassi sheep that gave birth in May 2021. The sheep were given roughage containing dry matter with 2.5% of their body weight and concentrated feed (2400-2600 kcal ME and 15-16% Crude Protein) as the 40% of their milk yield each day during the lactation period. The experimental ewes were randomly assigned into two groups with 20 animals in each. While the control group sheep were managed with normal day-time length during the lactation, the photoperiod restriction group were kept in the shed with 16 hours of darkness and 8 hours of daylight for 2 months. At the end of the two months, ewes of the both groups were managed in normal daylight until the end of lactation period. During the photoperiod restriction term, milk samples were taken at an interval of 15 days, while the milk composition was determined by a milk analyser and melatonin contents were determined by using LC MS/MS. In addition, lactation milk yield and lactation periods were estimated for all sheep. Statistical evaluation of the obtained data was done by using the SPSS package program. At the end of the study, the application of the extended dark period was found to be affected milk yield (P<0.05) as well as melatonin amount in the milk (P<0.001). Significantly higher melatonin amount was observed in the milk of sheep kept in a long-term dark environment compared to those exposed to normal photoperiod (11.1±7.24 pg/ml vs 6.1±4.55 pg/ml; P<0.001). As a result, it was determined that the prolonged dark period during a day increases the milk melatonin content. It can be also stated that the sheep's milk to be produced with this application could be a product that could take place in the functional food market.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139616101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
