In Iraq, due to the government’s lack of control over antibiotic use by the aquaculture farmers, random use of antibiotic is prominent, especially Oxytetracycline (OTC). Oxytetracycline is a potent antibiotic used in aquaculture industries because it is easily obtained, inexpensive, and effective against bacterial diseases. The present study aimed at quantifying and comparing the amount of OTC residue in the two most consumed muscles, dorsal and caudal skeletal muscles, of farmed common carp fish ‘Cyprinus carpio’ by the Sulaymaniyah population. Samples of caudal and dorsal skeletal muscles of 54 (for each muscle type 27) carp fish were taken randomly from 9 large aquaculture ponds, which were composed of one or more earthen ponds, in Qaladze and Taqtaq areas near Sulaymaniyah Province/Iraq. The OTC residue was quantified using high-performance liquid chromatography (HPLC). Two-tailed, unpaired t test analysis of the results was performed by GraphPad Prism software to compare between the residue levels in the two regions of the skeletal muscles. Twenty-eight samples had OTC residue detected in them, while residues in twenty-six samples were not detectable, only two of the caudal skeletal muscle samples had residues that exceeded the Maximum Residual Limit (MRL), while all the dorsal muscles with OTC residues revealed lower levels than the set MRL. The present study revealed that there was OTC residues in common carp, and different muscles have OTC residues regardless of their location in the common carp’s body. In addition, a specific MRL level and a legal regulation by the Iraqi government must be set to keep OTC use for the farms and residue levels in the fish meat under control.

The objective of the current study was evaluating the status of blood serum biochemical parameters in poorly controlled diabetes mellitus induced after experimental total pancreatectomy in local crossbreeding dogs. The biochemical assay was taken before the surgical operation and on the last two days of the insulin treatment period and after termination of insulin therapy till death of animals due to ketoacidosis after detecting severe ketonuria on urinalysis by urine stripe test when insulin withdrawn. Results of estimating the various biochemical parameters revealed a significant increase in the blood serum level of liver enzymes [Alanine amino transaminase, alkaline phosphatase, and Aspartate amino transaminase], total cholesterol and potassium ions, while a significant decrease in chloride ions took place in both insulin treatment and withdrawal periods. On the other hand, significant increases in blood serum levels of triglyceride, total bilirubin, sodium ions, and blood urea nitrogen with significant decrease in total calcium was occurred in the insulin withdrawal period only. In conclusion, the first mentioned biochemical parameters might be involved in the pathogenesis of poorly controlled diabetes mellitus while the later mentioned parameters which exhibited significant changes only after cessation of insulin therapy might be involved in the pathogenesis of surgically induced diabetic ketoacidosis in dogs.

The current study aimed to ascertain the impact of acute codeine dose (0.50 and 1 ml/ 250g), on the histolopathological profile of the liver and kidney in male rats. A synthetic antispasmodic substance with comparatively low toxicity is opioid derivatives (Codeine), In present study results found that normal histological structure, except Some minor changes were shown in the control group (antihistamine syrup, which does not contain codeine), while the groups II and III contain overdose treatment of codeine were reveal that the over dose of codeine involved inflammation cells infiltrations in the liver parenchyma, congestion of blood vessel, fatty degeneration, cytoplasmic vacuolation, and pyknotic of hepatocytes nuclei. However, renal damage profiles were seen in the kidneys of treated rats, kidney reveal necrosis, cytoplasmic degeneration of lining of the renal tubules, and enlarged lumen intracellular space. Red blood cells flooded the intertubular gaps and congested the renal blood vessels. conclusion that opioid derivatives (Codeine) poisoning caused renal and hepatocellular damage

NF-B (Nuclear Factor Kappa B) is a crucial transcription factor that is essential for host survival during pathogen infection in animal and human. Therefore, it has been a main goal for numerous pathogens to modify cellular NF-κB activity to create an environment conducive to their survival within the host.  In the present study, the cell line type (SW480) was used as a model of colon cancer cells.  Subsequently and through using western blotting, the effect of ORF3 protein on TNF- induced NF-B activation was observed by detecting the NF-B p65 subunit in the nuclear and cytoplasmic extracts. The results appeared that p65 translocated into the nucleus when stimulated by TNF-α in the control groups (GFP and mock cells). However, weak nuclear translocation was seen in ORF3-expressing cells. Moreover, the experiment revealed the ORF3 protein in SW480 inhibited the nuclear translocation of the p65 protein. After TNF-α stimulation, the difference in the band intensity of NF-κB protein in the nuclear fraction of control groups cells from each GFP group (A3) and mock cells (B3) was significantly higher compared with nuclear extract from Orf3expressed cells (C3 , P = 0.0001). In conclusion, the current study was confirmed that HEV ORF3 protein inhibits the activity of cellular NF-κB in human colon cancer cells.

      Goats play a significant role in the economy of Iraq through livestock production, income generation, employment opportunities, and the conservation of valuable genetic resources. Genetic diversity of three Iraqi local goat breeds were studied by using two molecular markers, fifteen microsatellite (SSR) and fifteen RAP DNA markers. Individual blood samples were collected and individual genomic DNA were extracted from 30 Black, 10 Hybrid, and 20 Meriz goat breeds. PCR amplification was conducted. The results revealed that out of 15 SSR primers, 11 were amplified and showed 847 total bands, 53 were polymorphic with 6.58 percentage of polymorphic bands. All the fifteen RAPD primers amplified 6085 total bands, in which 273 were polymorphic bands with 4.33 percentage of polymorphic bands. Different unique bands were detected for each breed. Both SSR and RAPD gave moderate polymorphism 66.67% and 61.52%, respectively. Besides, this value was consistent with the moderate value of the mean of polymorphism information content 0.19 and 0.28, respectively. Meriz and Hybrid breeds revealed the longest genetic distance (0.114 and 0.316). While, Black and Meriz breeds revealed the highest closeness (0.956 and 0.831) for SSR and RAPD markers, respectively. Furthermore, the UPGMA dendrogram for both of SSR and RAPD markers classified the three goat breeds into two main clusters. The first one contained Black and Hybrid breeds. While, the second one contained only Meriz breed. The results of the current study will be helpful for future researchers as a key guide to better understanding the genetic relationships and breed differences in Iraqi goat breeds for planning strategies for the future genetic improvement program.

Influenza A viruses spread naturally among aquatic birds, especially the wild ones. The aim of the current study is to investigate the avian influenza virus subtype H9N2 in the wild and domestic ducks in different geographical areas of Basrah Governorate, namely Shatt Al Arab, Abu Al-Khaseeb, Az Zubayr, and Al Qurnah. The presence of the virus was initially investigated generally using a pair of universal primers by performing the reverse transcriptase polymerase chain reaction. Subsequently, the virus subtype H9N2 was detected in both bird species. The results showed that the overall prevalence of the virus, regardless of subtype, was 66%. The total percentage in wild ducks was 78.6%, which showed significantly higher values than what was in domestic ducks, where it was 52.8%. Regarding the spread of the virus according to geographical location, the percentage of viruses in wild ducks was comparable in all areas involved in the study, while in domestic ducks it was higher in the Al Qurnah region, northern Basrah Governorate, compared to the rest of the regions.

A hydrophilic polyethylene glycol-based adhesion barrier (SprayGel™) was tested on intra-abdominal adhesion in conventional celiotomy in rabbits. Twenty healthy male rabbits of the local breed were randomly divided into two equal groups: control and treatment. All the experimental rabbits were first subjected to mid-line conventional celiotomy under general anesthesia. The ascending colon was tracked out of the laparotomy opening, and a sterile soft toothbrush was used mechanically to abrase its serosal and subserosal layers. Before closing the celiotomy opening, 2 ml of sterile saline solution was applied intraperitoneally into the abdominal cavities of the control group. SprayGel™ was applied to the test rabbits' abraded colons before their closures. Postmortem examinations were performed on the 14th and 21st postoperative days to assess intraperitoneal gross pathological changes, and biopsies were collected for histopathological examinations. The macromorphological and micromorphological examinations showed mild postoperative intra-abdominal adhesion changes in the treatment compared to the control. This was confirmed by significantly lowered gross intra-abdominal adhesion scores with the slightest micromorphological changes in the SprayGel™-treated rabbits. Higher scores of gross transperitoneal adhesions were observed in the control rabbits. In addition, histopathological changes were seen as serosal scars, consisting of raised areas of fibrous tissue replacing the muscularis layer of the mechanically abraded ascending colon, often to the submucosa level. SprayGel™ was an effective barrier substance to reduce intra-abdominal adhesions following celiotomy and experimentally induced mechanical serosal and subserosal abrasions to the ascending colon in rabbits.

This study investigated the impact of sodium hyaluronate and platelet-rich fibrin on the healing process of symphyseal fractures in cats. To conduct this study, 30 adult male cats were utilized and divided into three groups (10 cats each). The groups consisted of a control group (no treatment), a sodium hyaluronate group (treated with sodium hyaluronate gel at the fracture site), and a sodium hyaluronate combined with platelet-rich fibrin group (treated with a mixture of sodium hyaluronate gel and platelet-rich fibrin at the fracture site). The symphysis fractures were induced via a surgical scalpel, and the fractures were then fixed using a cerclage wire. The cats were observed clinically on the first, second, third, and seventh days following the surgery, and Histopathological assessments were conducted 42 days after the surgery. The study showed improvement in the disappearance of swelling in the fracture area among the treated groups. Interestingly, cats were observed to regain the use of their jaws just three days post-surgery, which was not seen in the control group. Histological findings indicate complete fracture healing in the Sodium Hyaluronate-Platelet Rich Fibrin (SH&PRF) group, with active bone remodeling, cartilaginous callus formation, and peripheral fibrous reaction without inflammation. The SH&PRF group showed more active chondrocytes and endochondral ossification than the SH and control groups, suggesting better bone repair results. The study suggests that Sodium Hyaluronate and platelet-rich fibrin composite effectively promote and accelerate wound healing.

In the context of health monitoring of a group of cattle and buffalo farms in marsh and swamp areas, these animals displayed evident clinical signs of nutritional deficiency in addition to symptoms that included high temperature (41 °C or higher), swollen lymph nodes, diarrhea, anemia, weakness, and decreased appetite. And, in some cases, cough. The presence of ticks in various areas of the body, especially the edges of the ear, the neck area and the area beneath the tail, indicated the possible presence of Theileriosis, a parasitic infection. Random blood samples were collected from sixteen individuals. Subsequently, DNA was extracted from these samples and Polymerase Chain Reaction (PCR) was utilized to amplify the small subunit of the 18S rRNA gene, which is highly specific for the detection of Babesia/Theileria species. The PCR procedure employed the GF (5'-G(C/T) (C/T) TTGT AAT TGG AAT GAT GG-3') and GR (5'-CCA AAG ACT TTG ATT TCT CTC-3') primers. The results were then compared to international isolates via an analysis of genetic nucleotide sequences using the Basic Local Alignment Search Tool (BLASTn) algorithm, available at the National Center for Biotechnology Information (NCBI). This analysis unveiled a significant genetic resemblance between the 18S rRNA gene sequences and T. annulata species, suggesting the presence of this parasite. As a consequential outcome of this study, it has been established that Bos taurus and Bubalus bubalis, can be a new host for T. annulata, particularly in the southern regions of Iraq. 

 Newcastle disease (ND) is an endemic viral illness in Iraq and has four types: viscerotropic velogenic, neurotropic velogenic, mesogenic, and lentogenic. The virulence of the virus continuously increases, and it is widely spread in wild and domestic birds. Backyard and poultry farm chickens are mainly affected, causing significant economic losses, as the disease is famous for high morbidity and mortality, which may reach 100%. An outbreak of velogenic ND spread in poultry farms in Sulaymaniyah/Iraq in early 2023, causing high mortality rates. Hence, this study was conducted to isolate and identify the virus and determine its median embryo lethal dose (ELD50) in embryonated chicken eggs (ECEs). Samples were taken from chickens suspected of ND, and NDV identification was made by molecular techniques by amplifying part of the 535-base pair-F gene. The virus was passaged three times in ECEs, and the collected allantoic fluid was used to determine the ELD50. After that, fifty ECEs were used to calculate the ELD50. Allantoic fluid dilutions of 10–107 resulted in the death of all embryos after 2-3 days, with distinctive signs of bleeding and hemorrhage. Dilutions of 108, 109, and 1010 resulted in the death of four, two, and one embryo, respectively, and the PCR test revealed NDV infection. The ELD50 was 6.3 ×108 times the allantoic fluid dilution, showing that the virus was very velogenic and necessitated a strict control plan to prevent the disease's further spread.
