“…Small ruminants, especially sheep are valuable possessions for the Southeast Asian, Mediterranean, and African countries that benefited from their milk, meat, and wool (1)(2)(3). In sheep-rearing countries, infections of the respiratory tract are of major concern due to their impacts on the income and nutrition of people (4,5).…”

Sheep are considered as an important part of livestock in the worldwide, particularly in Iraq, as they provide meat, milk, leather, wool, and manure. The present study aim is isolation and identification of staphylococci, enteric bacteria and Pseudomonas spp. Totally, 115 samples were collected from sheep (100 samples were collected from the nasal cavity of local sheep suffering from respiratory infections, and 15 samples were collected from apparently healthy local sheep). All the samples were collected from seven flocks located in Abu Ghraib and Al-Radwaniyah, Baghdad governorate, Iraq. The samples were taken during the period from October 2020 to February 2021. Staphylococcus spp., Pseudomonas spp., and enteric bacteria were detected firstly by using classical diagnostic methods, and secondly they were identified to the species level by using the corresponding analytical profile index (API 20 staph, API 20NE and API 20E) and via the Vitek2 system. Importantly, from nasal swabs, 79% bacterial isolates were obtained, including Enterobacter cloacae, Escherichia coli, Raoutltella planticola, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus among others. The antimicrobial susceptibility test showed multi-drug resistant S. aureus, P. aeruginosa and K. pneumoniae. To conclude, several aerobic bacteria were isolated from the nasal cavity of diseased sheep. An extensive study is needed to determine the economic and public health impacts of these bacteria.

“…Based on these data, OLR1 gene variation causes several damaging aspects on oocytes, which could adversely affect fecundity traits. Consequently, the Awassi breed is characterized by a high level of adaptability to harsh environments [42] with a lower reproductive capacity [43,44].…”

“…Blood samples were obtained from jugular vein of all lambs at1 st , 3 rd and 4 th weeks post 2 nd immunization, sera were isolated by centrifugation at 2000 rpm for 15 min (17). The cytokine concentrations of IL17, IFN-γ and MIF were estimated according to the manufactures guidelines of the sheep ELISA Kit (MyBioSource USA).…”

This study was designed to prepare and evaluate the specific Mycobacterium bovis (M. bovis) Bacillus Calmette-Guerin (BCG) transfer factor (TF) from spleen cells of two lambs vaccinated subcutaneously S/C with BCG vaccine twice 2 weeks' intervals, similarly one lamb injected with normal saline used as a donor of non-specific TF. The lambs were clinically examined at zero time and along 3 days post each immunization, then, delayed type hypersensitivity (DTH) was checked post 4 weeks. TF was obtained from spleen cells of the lambs, inspected for sterility; safety.TF was evaluated in 4 groups (five in each) of lambs 3-4 months old. The first group (recipient) was injected S/C with 2 ml of specific BCG-TF, similarly the 2nd, 3rd and 4th groups were injected with nonspecific TF, BCG and normal saline respectively. The clinical signs and DTH test were checked as described above, only the specific TF recipient and BCG vaccinated lambs gave a positive DTH test. The serum concentration of inerlukin-17 (IL-17), interferongamma (IFN-γ) and migration inhibitory factor (MIF) cytokines were measured by Enzyme-linked immunosorbent assay (ELISA), which revealed a highly significant increase in the TF recipient lambs in comparison with the control and vaccinated groups. It concluded that the prepared specific M. bovis-BCG transfer factor was effective to induce cell mediated immunity via DTH and increasing the serum concentration of cytokines in recipient lambs.
