Salmonellosis is a zoonotic infection of humans and animals. In recent years, an increase in the number of resistant strains of Salmonella from animals and animal products have been recorded. We conducted microbiological testing and antibiotic resistance profile of 34 Salmonella strains isolated from foods of animal origin between 2018 to 2021 in Ukraine. Twenty isolates were successfully assigned to six different serovars [S. Enteritidis (n=13, S. Infantis (n=2), S. Schwarzengrund (n=1), S. Livingstone (n=2), S. Vuadens (n=1) and S. Hadar (n=1)], and 14 isolates remained untyped. Most of the isolated strains were recovered from poultry products. The strains were tested for six antibacterial groups: quinolones, aminoglycosides, β-lactams, cephalosporins, phenols, and dihydrofolate reductase inhibitors by disc diffusion method. The highest level of resistance was recorded to 4th generation cephalosporins, e.g., cefepime (88.2%). The lowest level of resistance was to cefotaxime and ceftriaxone (5.9%). No resistance was found to imipenem and aminoglycoside antibiotics, particularly gentamicin and amikacin. The study results are of concern because antibiotic-resistant bacteria and their genes can cause human infections by penetration and transmission at any stage of the food production cycle. Further research is required to monitor the contamination of food products of animal origin with salmonellosis pathogens, including antibiotic-resistant strains

The present study's objective was to evaluate the inhibitory activity of the Probiotics Lactobacillus acidophilus and Bifidobacterium (obtained from the Agriculture Research Directorate, Ministry of Science and Technology, Iraq) and a suspension of a mixture between the two mentioned probiotics with two types of Gram-negative bacteria (Pseudomonas spp and Proteus spp) and one type of Gram-positive bacteria (Streptococcus spp) in vitro. The required tests were completed to verify the probiotics' purity, and the bacterial isolates used in the current investigation were assessed using biochemical assays and selected culture medium (culture and microscopic features). In addition, the inhibitory efficacy of the investigated Probiotics in different Gram positive and negative bacteria was evaluated by drug susceptibility testing (disc diffusion test as well as agar well diffusion test). Our data of the current study confirmed an excellent inhibitory activity of each Bifidobacterium (B) and the mixture of the two probiotics (MLB) via measuring the inhibition area, they had 25, 22mm, 28,-30 mm inhibition zone for Pseudomonas spp, 23, 25 mm, 26-27mm inhibition zone for Proteus species spp, and 22,20 mm, 33,29 mm inhibition quarter for Streptococcus species, by way of the usage of disc and agar well diffusion methods respectively. Where it was once weak inhibition activity of Lactobacillus acidophilus (L)on Pseudomonas spp, 0-3 mm and Streptococcus species 1-7 mm by the usage ofthe disc and agar well diffusion respectively. On the other, hand, Probiotic(Lactobacillus acidophilus) had available zone of inhibition on the Proteus sppbacteria, which were 24, 24 mm through the disc and agar well diffusion respectively. In conclusion: the Probiotics were found to have good and active inhibitory action on Gram-positive microorganism (Streptococcus) and gram-negative microorganism (Pseudomonas and Proteus) in vitro by way of using disc and agar well diffusion test, and the combination of the two probiotics MBL of present study, had more potent inhibitory action than each one of the studied separate probiotics.

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

Penicillium is a genus of the one the most common fungi have located in distinctive and suitable surroundings (temperature, humidity, Ph), Penicillium species produced extracellular enzymes that play a necessary position in the microbial decomposition of natural substances. The study is aimed to detect chemicals made by two species of Penicillium using a synthetic media that contained a powder made from the leaves of the Conocarups tree.

Contamination of edible animal products with veterinary drug residues is a potential health hazard for consumers. A method for extracting rafoxanide anthelmintic drug from sheep muscle was adopted based on a QuEChERS approach followed by high-performance liquid chromatography (HPLC-UV). The developed method has been fully validated according to the requirements of Eurachem-2014 by separating the standard anthelmintic drugs on a fast liquid chromatographic (FLC) reversed-phase column under the optimum separation condition. The mobile phase consists of solvents A and B, degassed with an ultrasonic bath to remove bubbles. The standard calibration curves (R²≥0.9961) were constructed with spiked certified reference materials (CRM) and blank tissues. The optimized approach was validated, yielding satisfactory results for all performance criteria in the tested matrix and obtaining relevant results for all performance parameters in the evaluated matrix. A multi-level calibration curve (1 to 1000 µg/kg) was used to establish instrument linearity for rafoxanide. The recoveries were 83%, the limit of quantification was 10 μg/kg, and the detection limit was 0.22 μg/kg. The results of the validation allowed for high sample throughput. The method is suitable for analysing selected anthelmintic drug residue, and repeatability and reproducibility expressed in relative standard deviation (RSD%) were obtained at values lower than 20%. None of the testers were greater than Maximum Residual Limits (MRLs) legally established by the European Union (EU). 13 (26%) (n=50) samples were below MRLs, and 37 (74%) (n=50) samples were below the LOD.

         Avian metapneumovirus (AMPV) is a worldwide an acute, extremely contagious upper respiratory illness in Turkey. Chickens may also be affected with virus and cause Swollen Head Syndrome. Sometime it is associated with reproductive affection. The disease's first disorder appeared in late 1970 in South Africa, where 6 subtypes (A, B, C, and D) and 2 additional subtypes were found. The virus belongs to the family Paramyxoviridae, genus Metapneumovirus. . Both of systemic and local immunity may be developed but there is no relation of maternal immunity for produce production. The disease causes an important economic loss due to decrease in egg production and bad egg shell quality. The disease spread between birds rapidly and a wild birds may be infected and paly role in transmission of the disease Also in turkey there is no specific clinical signs and lesion and while the most effective methods to detection are Elisa and (RT-PCR) carry out the disease diagnosis. Biosecurity programs of vaccination are effective for controlling of disease. Both of alive attenuated and inactivated vaccines are useful for provide a good protection against the disease While, new vaccines were developed to avoid infection.
