Fifty four skinks were collected in April and May 2019 from Baltim, Kafr El Sheikh Governorate, Egypt and examined for the presence of Coccidia. The prevalence recorded as 24.1% and it was higher in males than females. Oocysts were shed unsporulated, in early stages of sporulation and rarely sporulated. Events of sporulation and sporulation time were described. The sporulated oocysts, limited by bilayered wall, were spherical to subspherical measuring 21-25.6 x 19.2-23.4 μm. No micropyle, polar granule or oocyst residuum was noticed. The sporocysts were ovoid to ellipsoidal measuring 13.2-15 x 8.5-9.5 μm. Stieda, substieda bodies and sporocyst residuum were present. Experimental infection by sporulated oocysts was carried out and the developmental endogenous stages (merogony and gamogony) were followed up and described. The prepatent and patent periods were 6 and 4 days, respectively. Endogenous stages took place in the lamina propria and enterocytes of small intestine of the experimentally infected skinks. One generation merogony was occurred at 24-72 h p.i. The mature meronts measured 5.5- 18.8 x 5.4-17.3 μm and yielded up to 28 merozoites. Gamogony occurred at 84-96 h p.i. The mature microgamonts measured 11.1-12.6 x 8.4-11.2 μm and contained 16-40 small nuclei while the mature macrogamonts measured 15.2-18.2 x 14.8-16.4 μm and contained a large central nucleus and the two types of wall-forming bodies. Newly-formed zygotes or young oocysts were seen at 120 h p.i. measuring 16.8-20.2 x 14.2-17.8 μm. In addition, the checklist of Isospora spp. infecting the Egyptian reptiles, including the present species, was provided.","PeriodicalId":342785,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Zoology)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122737077","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}

This denotes a high possibility that contaminated the diet of man and his farm animals this fact alarmed some scientists to study their biological influence. Ginger (Zingiber officinale) has been used as an antioxidant and preventing agent against numbers of diseases. The study deals with effects of brodifacoum on the chromosome and on the liver and testis of male mice as well as and the protective effects of ginger extract. 130 Adult albino male mice were used in this study. Group (G1) served as control. Groups (G2&3) was received ginger extract doses 1.5% and 3%. Groups (G4&5) received single dose (1/10 LD50) of brodifacoum for group (G4) and (1/20 LD50) for group (G5). Groups (G6, 7, 8 & 9) received brodifacoum then ginger extract. Groups (G10, 11, 12&13) received ginger extract then brodifacoum. Animals from all the groups were sacrificed and their bone marrow cells were analyzed for chromosomal damage. Liver and testis samples are collected for histopathological examination. The animals of the groups that treated with brodifacoum showed significant increase of chromosomal aberrations and the value of mitotic index were reduced. Treated male mice with brodifacoum induced various histological changes in liver and testis. Treated animals with brodifacoum and ginger lead to reduction in chromosomal aberrations, significant increase in mitotic index and slight improvement in the histological change in liver and testis. Results obtained from this study demonstrated that brodifacoum has a mutagenic effect on chromosome and histopathological change in different organ (liver and testis) and the use of ginger may be a potent protective against the toxicity of brodifacoum anticoagulant rodenticide.","PeriodicalId":342785,"journal":{"name":"THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY (Zoology)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125793864","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}
