It is used to control fungal diseases for a wide variety of crops because its broad-spectrum fungicidal effects and high compatibility with agrochemicals. The objective of this study was to investigate the effects of the fungicide mancozeb at different doses on some biochemical parameters, reproductive performance and histological changes in testes and thyroid gland. The low dose equal 1/7 of LD50 manc-d1 and high dose equal 1/3.5 of LD50 manc-d1. Doses of mancozeb (manc-d1 and manc-d2) adjusted according to rat's body weights. The results showed that mancozeb significantly (P<0.05) decreased plasma testosterone level, sperm count, viability, motility, and significantly (P<0.05) increased abnormal sperms, altered acrosome and abnormal DNA. Treatment of rats with manc-d1 and manc-d2 significantly (P<0.05) decreased T3. Also, T4 significantly (P<0.05) decreased in the group treated with manc-d2. Treatment of rats with manc-d1 and manc-d2 significantly (P<0.05) increased TSH. Furthermore, the histological investigation revealed that exposure to mancozeb reduced number of mature spermatozoa, necrosis and basal vacuoles observed in some tubules. On the other hand, mancozeb reduce colloid in most follicles resulting in desquamation of the follicular epithelium into the lumen of the thyroid follicles. In conclusion, despite mancozeb exhibit low acute toxicity, it has been shown to cause detrimental effects on reproduction, thyroid gland and its secretion. For this reason, it should be necessary to be careful when using mancozeb in agricultural areas and should take precautions.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"107 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72631625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, its long-term administration causes testicular adverse effects. Carvacrol is a phytochemical derived from aromatic plants of the genera Oregano. It is known to have anti-inflammatory and anti-oxidant effects and to inhibit the growth of a variety of cancer cells. The present study was designed to evaluate the antioxidant effect of carvacrol on MTX-induced testicular damage. Twenty-four adult rats were randomly divided into four groups, six rats each, as follows: Control, Carvacrol (40mg/kg b.w. daily orally), MTX (25 mg/kg b.w single shot I/P) and Carvacrol and MTX. Testicular biomarkers, redox status and Nrf2 gene expression tests were assessed after 15 days. MTX caused alterations in testosterone hormone and total and prostatic acid phosphatases. Furthermore, testicular 8-OHdG and MDA were increased while reduced GSH was decreased indicating testicular oxidative damage. Concomitant administration of carvacrol was able to restore the adverse effects of MTX. This was observed in the revised levels of the mentioned parameters nearly to normal in comparison to the control and MTX groups. In the present study, we report that carvacrol ameliorates MTX-induced testicular damage by protection from oxidative stress, decrease in DNA damage, and enhancement of serum testicular biomarkers.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76566947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four hundred and eighty four fish samples of Clarias gariepinus at various developmental stages were randomly selected from fish farms across the three agro – ecological zones in Lagos Stata, Nigeria. The samples collection lasted eighteen months covering both wet and dry season while parasitology and histology examinations were carried out in a laboratory using standard methods.. The wet mounts were prepared for skin and gills. Water quality parameters monitored were pH, water temperature, dissolved oxygen, ammonia, nitrite, iron concentration, alkalinity, hardness and turbidity according to respective manual guidelines. Descriptive statistics such as frequency count, percentages, standard deviation were used to determine the level of prevalence, occurrence and distribution of the parasites. Argulus species (Branchiuran) was the only parasitic crustacean observed in this study with low prevalence and intensity of infection of 1.05% and 2 respectively found on the gills of fingerlings during the rainy season. The histological examination on infected gill revealed no alteration. The water parameters were within the acceptable limit for fish survival. The low prevalence and loads of Argulus sp indicated good management practices which possibly suppress the propagation of the parasites despite the expected influence of optimum temperature and low dissolved oxygen in favour of the parasites. Therefore, good management practices should be encouraged to reduce rate of parasitic infection that often being a primary pathway to secondary infections.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75472574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study sought to establish the prevalence of Cysticercus bovis, histopathology, and its economic effect on slaughtered cattle from Egypt's El-Menofia Province. The inspection of 4670 cattle carcasses, 2500 male and 2170 female, was done over two years, from March 2019 to February 2021, at three abattoirs (El-Shohada, El-Bagour, and Menof). The findings showed that 0.69% of slaughtered cattle had C. bovis. The prevalence was highest in summer and autumn at 0.195% followed by winter at 0.17% and spring at 0.13%. Females were more susceptible than males to infection at 0.58% and 0.11%, respectively. The presence of C. bovis was associated with the age of the inspected carcass. The increased prevalence was observed in female cattle older than 5 years. The predilection sites were masseter muscle (0.23%), heart (0.44%), and entire carcass (0.04%). Heavy infection with C. bovis was observed in two cases in El-Bagour abattoir. The recovered C. bovis morphology and histopathology were documented. Grossly, C. bovis was found either an oval live fluid-filled cyst or a degenerating dead cyst with dystrophic calcification. Histopathology of C. bovis in cow muscle showed its sucker, central spiral convoluted canal, and oval-shaped basophilic calcareous bodies. The parasite was surrounded by the host inflammatory cells. C. bovis was found live, dead, or calcified and ranged from 5-8mm in diameter, with local or heavy infestation. Cysticercosis caused significant economic losses, with an estimated total annual loss of 57970 Egyptian Pounds from the condemnation of organs in this study's inspected carcasses and a total of 1935150 EP from the total condemnation in the three abattoirs included in this study, including ours. This low prevalence of infection suggests using a good drainage system to protect cattle intermediate hosts of T. saginata to prevent human infection.","PeriodicalId":7928,"journal":{"name":"alexandria journal of veterinary sciences","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77866137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
