Different risk factors associated with camel brucellosis were investigated in these camel's populations, these include the rearing of camels with different ruminant’s species, addition of new animals, as well as lack of sanitary measures. The modified Rose Bengal Test and Complement Fixation Test revealed a prevalence of 40 (14.8%) and 32 (11.9%) respectively. The three districts with the highest prevalence of camel brucellosis were Belbeis (14.12%), EL Husseiniya (12.19%), and Minya al-Qamh (10.7%). Three (9.4%) brucella species were isolated out of 32 milk samples from serologically positive she-camels. Two isolates were identified as B. melitensis biovar 3 and one isolate was identified as B. abortus biovar1. Bru-cella strain DNA extracts from milk samples showed a specific amplicon of 731 bp specific for B. melitensis (18) and an amplicon of 498 bp specific for B. abortus (4), but no amplicon of 285 bp specific for B. suis could be detected after being subjected to PCR using the IS711 primer in this investigation. We concluded that, in this study, Brucella meliteneis biovar 3 is a common field strain in camels. Oxidative stress biomarkers, malonaldehyde (MDA) were increased significantly ( P ≤ 0.05) in infected camel, whereas nitric oxide (NO) was moderate increase. Antioxidant enzymes like Gluta-thione Peroxidase enzyme (GPx) was significantly increase whereas catalase (CAT) was significantly reduced in infected camel. This study has confirmed our understanding of risk factors associated with camel brucellosis. The rearing of camels with different ruminant’s species, the addition of new animals, and the lack of sanitary measures were the primary risk factors associated with the spread of brucellosis among dairy camels .","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91369053","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}

West Nile Virus (WNV) is a zoonotic virus that threatens health of humans and animals and causes several epidemics for both hosts. Additionally, it has economic losses due to the expense of treatment of diseased cases, control programs, and animal losses. The epidemic spillover and spreading of the viruses is geographically distinguished in the last few decades. The epidemiological features of WNV are controlled by its insect vectors, their geo-graphical distribution, climatic changes, and changes in arthropods' habitat as a consequence of the change in urbanization behavior as well as the global travel movements. National and international surveillance for WNV transmission is an important strategy to track the virus's spread and effective management methods.","PeriodicalId":11415,"journal":{"name":"Egyptian Journal of Animal Health","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82880449","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 pandemic of highly pathogenic avian influenza virus (HPAIV) H5N1 (clade 2.2.1.2) has been spreading through the country since 2006. In 2016, the Spread of HPAIV H5N8 (clade 2.3.4.4b) to Egypt via wild birds into commercial poultry flocks made overburden on the economic situation of poultry business. The surveillance efforts conducted by the governmental veterinary authority GOVS showed dominating infection of H5N8 with rare spread of H5N1 in poultry market sector. Thus, the current study try to figure out whether a replication competence exhibited between the two highly pathogenic avian influenza viruses HPAIV H5N1 and H5N8 through designation an in-vitro induced infection of H5N8 and H5N1 in specific pathogen free embryonated chicken eggs (SPF-ECE). A concentration of 10 3 EID50 of HPAIV H5N1 and H5N8 were either sequentially or simultaneously inoculated into the allantoic cavity of SPF-ECE at 48 h of incubation, followed by the collection of allantoic fluid. A quantitative reverse transcription real-time polymerase chain reaction was used to determine the quantitative replication of viral RNA copies of neuraminidase gene of both AIV strains. A replication competence was observed according to which viral strain firstly inoculated. Whereas, H5N1 RNA titers was reduced by ≥4log 10 when H5N8 firstly inoculated. Vice versa H5N8 RNA titers were reduced by ≥4log 10 when H5N1 firstly inoculated.
