ABSTRACT T he goal of this work was design to study the influence of lycopene and pine bark extracts as natural food additives as alternatives to nitrite, which poses serious health risks to consumers of processed foods containing this substance. These extracts were also found to be effective antimicrobial and antioxidant agents, particularly when used as an example in the current study for manufactured basterma. For this, Egyptian basterma were inoculated with 10 4 CFU g-1 of Staph. aureus and E. coli into raw meat separately, and then treated with a 1% concentration of lycopene and a 1% of pine bark extract. For the duration of the storage period, basterma was kept at room temperature for microbiological assessment and sensory analysis. Staph. aureus and E. coli levels decreased by 4 log and 2 log, respectively, on the fourteenth day. Additionally, Egyptian basterma sensory evaluation yielded a good, acceptable result. Therefore, as compared to the effects of nitrite, lycopene, and pine bark extract, they show strong antibacterial activity during product preservation. The findings provided here may indicate that lycopene and pine bark extracts offer protection against Staph. aureus and E. coli , which means they have the potential to replace nitrite as a natural preservative in the food production.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"36 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139540332","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}

No statistical significant difference of C. parvum were detected in Kareish cheese between microscopic examination, experimental infection and PCR. Microscopic examination of prepared yoghurt and Kareish cheese smears and experimentally infected rats fecal smears showed the spherical shape of C. parvum oocysts (4-6μm). A banana shape of C. parvum sporozoite (3.2x1.4μm) was found in fecal smear of experimentally infected rat by contaminated yoghurt. Meanwhile, the PCR identified the specific Actin gene of C. parvum in 3 yoghurt and 5 Kareish cheese samples. From the obtained results, it could be concluded that C. parvum oocysts remain viable in locally made milk products.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"77 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139458312","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}

ABSTRACT T he H9 low-pathogenic avian influenza (LPAI) viruses cause enormous economic harm despite their low pathogenicity. It became common in Egypt in 2011 and has undergone ongoing genetic evolution since then. To limit the virus's transmission, regular monitoring of its evolution is essential. The current study concentrated on the frequency and molecular characteristics of LPAI H9N2 viruses spreading throughout different Egyptian areas between 2020 and 2022. Using real-time PCR, 503 positive LPAI H9 cases were detected out of 29,319 cases, for a total prevalence rate of 1.7%. However, live bird market (LBM) had the highest LPAI H9N2 prevalence rate (10.6%), followed by household sector and farm (2 % and 1.3% respectively). The 33 samples were isolated in 11-day-old embryonated chicken eggs (ECEs) before being sequenced for partial hemagglutinin (HA). The H9 isolates were phylogenetically related to the Egy-2 G1-B branch (pigeon-like), which has been the prevalent circulating H9N2 genotype in Egypt since 2016. The findings of the sequence analysis revealed a clear genetic evolution compared to the original","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"57 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139128165","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}

Several effects have been observed that could be related to a changing climate such as increased shellfish contamination, harmful plankton events and the establishment of non-native species, but it is not clear that a changing ocean climate is responsible for these effects. Given the current predictions, climate change is unlikely to have a significant effect on Scottish mariculture over the next decade. However, within the next 50 years or more, the forecast changes are likely to result in noticeable effects. Sea-level rise may reduce coastal habitat suitable for bivalve cultivation in the south of the region (where Scottish mariculture is undertaken). Rising average water temperatures will result in faster growth rates for some species (e.g. Atlantic salmon, mussels and oysters) but prolonged periods of warmer summer temperatures may cause thermal stress, particularly for cold water species (e.g. cod and Atlantic halibut) and intertidal shellfish (oysters). However, warmer waters may provide opportunities to culture new species, or species that are currently economically marginal in UK waters.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79439255","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}
