“…This is done to prevent a rise in RT in homoeothermic animals, such as sheep (Singh et al 2016). The increase in HR in Awassi in our study was also documented by (Al-Azzawi et al 2017), which revealed that the HR of local Awassi was lower than that of Turkish Awassi. A possible explanation may be that more heat was dissipated through the skin as a result of increased circulation from the heart and lungs.…”

This research was carried out to analyze the hematological, biochemical and physiological characteristics correlated with climate temperature in Awassi and crossbred sheep. Two hundred fifty adult Awassi and crossbred sheep (Arabi x Hamadani) were used. Three times weekly, ten times for each breed, vital signs, including heart rate (HR), respiratory rate (RR), rectal temperature (RT), and skin temperature (ST), were recorded. The heat tolerance indices (HT) and the heat tolerance coefficient (HTC) were evaluated. SAS was used to conduct the analyses, which included variance and correlation analyses. Awassi had a significantly higher (P < 0.01) RR than crossbred in the summer under low stress conditions. Awassi HR was significantly lower than that of crossbred sheep, which recorded the highest value in summer. There were no significant differences in RT, HT and HTC between Awassi and crossbred sheep. MCH, MCV, and RDW increased substantially in Awassi sheep exposed to colder winter temperatures. In summer, Awassi's liver enzyme and triglyceride levels significantly decreased, while albumin levels increased. Both HT and HTC had negative correlations with RR. Therefore, it can be concluded that the Awassi breed is equally adapted to the region's hot and arid climate.

“…The prevalence rate in sheep aged 1-6 months was significantly higher than that of the other age groups. Lambs have a higher probability of infection than adults because lambs' immune system is still underdeveloped and depends mostly on innate immunity and maternal antibodies to protect against the Orf virus [14]. The result of this study was detected the high sero-prevalence of Orf virus IgM (73.63%) and IgG (89%) among the lamb with or without clinical signs of Orf virus infection.…”

Contagious ecyhyma Known (Orf, contagious pustular dermatitis, sore mouth, scabby mouth) a disease spreads easily and brought by the epitheliotropic. It’s endemic around the world and has a serious economic impact. This study aimed to understand the immune response mechanisms of the lambs to defense against Contagious ecthyma virus and molecular detection of the virus with the determining the sequence and mutant of the viral genome to 91 lambs (41 has clinical signs of Orfv and 50 control do not have clinical sign of Orfv) for the period extended from September 2022 to April 2023. Blood samples were collected from all above groups to apply for detection the level of IgM, IgG, IL-10, and IFN-γ of Orfv by ELISA test. Positive Orfv IgM was 75.6% infected lamb and 72% none infected, and positive Orfv IgG was 90.2% infected lamb and 88% none infected. The result was showed the level of IL-10 a significant increasing, in all Lambs positive IgM and IgG compared with control group. IFN-γ level showed non significant differences between all Lambs positive IgM and IgG compared with control group. Molecular detection of Orfv result was confirmed the positivity of all samples positive Orfv IgM. And the sequencing of the Orfv DNA showed a mutant in the some Allel compared with References strain registered at NCBI. Concluded: high prevalence of Orfv among lambs and happened mutants to the viral genome increased the virus’s virulence by affecting the immune response.

“…Then the inoculated eggs are incubated for 4-7 days or until the embryos die. After that, the allantois fluids harvested are tested with a hemagglutination activity (HA) test using chicken RBCs (15,16). Carrying out HA assay only is insufficient to correctly identify the PPMV-1, as all avian paramyxoviruses serotypes and avian influenza viruses (AI) show hemagglutination activity.…”

Newcastle disease (ND) is a viral disease of poultry and other bird species like pigeon (Columbi livia), it characterizes as devastating and contagious and it has been distributed worldwide. ND in pigeons is caused by pigeon paramyxovirus type 1(PPMV-1) which is an antigenic and host variant of the avian paramyxovirus serotype 1 (APMV-1), the disease in pigeons is termed paramyxovirosis and cause nervous signs with high mortality usually in the bird with kidneys infected with viscerotropic strains, and neural signs appeared individually. PPMV-1 was initially detected by hemagglutination activity (HA) and confirmed with hemagglutination inhibition assay (HI), and molecular-based techniques. Serological diagnosis of paramyxovirosis is necessary because of the similarity of the PPMV-1 infection with sodium chloride poisoning, pigeon herpes virus infection (PHV), and ornidazole overdose that cause same neurological signs. PPMV-1 infection can be controlled effectively by vaccination by specific vaccines associated with good biosecurity aspect
