Abstract

Salmonella is considered the most important cause of foodborne diseases. Identification of Salmonella typhimurium evaluated using bacteriological assay followed by PCR technique. In this study, 40 intestinal content specimens of poultry were collected randomly from different farms of Al-Qadisiyah province. Outs of 40 samples obtained, 14 isolates (35 %) were detected as Salmonella typhimurium according to conventional bacteriological characteristics, the Vitek 2 system for identification and molecular assays. Two sets of primers were designed for detecting invA and ssaP genes. These genes potent the virulence of Salmonella typhimurium. The primers were made in this study by using NCBIGenBank and design online. The primers were made by (Bioneer) company, Korea. Molecular assay of the isolates gives away specific PCR products of 677bp for the invA gene and 314bp for ssaP gene. The invA genes were amplified in 11 (78.5%) out of 14 isolates of Salmonella typhimurium, while ssaP genes were amplified in 10 (71.4%) out of 14 isolates of Salmonella typhimurium. The result of the study confirms the ability of these specific primers for detection of salmonella typhimurium in samples of chicken as well as the rapidly and sensitivity of the PCR method as a good tool for bacteriological identification.

Abstract

Mosquitoes are tiny creatures but could do a lot of damages to the people life and especially by transmitting dangerous diseases such as dengue fever transported by Aedes aegypti. The control of these bugs is hostorically challenging and difficult. This difficulty increases after the emerging problems of insecticide resistance. The gut flora(GF) in different animals has been detected to place an important role on the physiology of the intestine. This study was conducted to discover if the Bdellovibrio bacteriovorus is a member of the GF of the mosquitoes. B. bacteriovorus is a bacterium that has been found in the intestine of animals and healthy and patient humans but not in mosquitoes. Seventy adult mosquitos of Culex pipiens were used for extraction of the bacterial DNA from their intestine. The 70 mosquitoes were assigned randomly to 7 groups, 10 mosquitoes for each group to pool the amount of DNA extracted. Each mosquito was dissected under the microscope to isolate the intestine and use it later for DNA extraction. After the DNA had been extracted using a phenol/chloroform method, I subjected the extracted DNA to polymerase chain reaction (PCR) to detect the presence of this bacterium among the bacteria of the intestine using the following specific primers: Bd529F (5’-GGTAAGACGAGGGATCCT-3’) and Bd1007R (5’-TCTTCCAGTACATGTCAAG-3’) that amplify a 481-bp of the 16S rRNA gene. By the amplification that happened in all 7 groups, the result indicates the presence of Bdellovibrio bacteriovorus in the intestine of the Culex pipiens. Because this bacterium preys on Gram-negative bacteria, our results help to use this bacterium to fight insecticide resistance that caused by the degradation of these chemicals by gram-negative bacteria in the ingestion of these mosquitoes.

Abstract

Aminoglycosides (AGs) such as gentamicin (gen) are considered as the optimum therapy for many infections and diseases. Unfortunately, AGs treatment has been linked to acute kidney injury that is also referred to as nephrotoxicity. In the current study, we sought to explore the protective roles of peppermint (pep) and licorice (Lic) extracts as well as their mixture on gen-induced nephrotoxicity. Forty male and female Wistar albino rats were divided into 5 experimental groups: C- was administered with 2 ml of normal saline as a single daily dose intraperitoneally (i.p.) for 14 d. C+ was administered with once-daily i.p. injections of 100 mg/kg BW gen for 8 d. T1 group was administered once-daily i.p. of gen (100mg/kg BW) for 8 d. and Lic ethanolic extract (EE) (100mg/kg BW) every 12 hr for 14 d. T2 was administered once-daily i.p. of gen for 8 d. and pep EE (100mg/kg BW) every 12 hr for 14 d. T3 was administered once-daily i.p. of gen for 8 d. in addition to lic and pep EE mixture (100mg/kg BW) every 12 hr for 14 d. At the end of the study, all rats were anesthetized and trunk blood collected to study renal injury parameters. Those include serum enzymes such as AST, ALT, and ALP; kidney damage markers including urea, creatinine, and total protein; serum electrolytes including Cl, K, and Na levels as well as other renal function markers such as Glutathione peroxidase (GSH) and superoxide dismutase (SOD). All the parameters that indicated the nephrotoxicity occurrence in the C+ group in response to gen were found to be highly improved in most of the studied aspects in T1, T2, and T3. We found that Lic and pep extracts improve renal injury, kidney damage, and renal function markers opposed to gentamicin treatment. In conclusion, our study suggests prescribing those remedies to AGs receiving patients.

Abstract

This study aims to clarify the accumulative effects of Sodium Nitrate at the level of 200 mg/lit that added to drinking water on broiler chicks. 120 of one-day-old broiler chicks (Hubbard Classic) were used. They were divided into two equal groups using 3 replicates 20 chicks for each replicate in 49 days. Group one (control) received just plain tap water. Group two received 200 mg/lit Sodium Nitrate. Weights were taken weekly. Feed conversion ratio, dressing percentage, Liver weight, humoral immunity against Newcastle disease and liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured a couple of times during the experiment. These two tests were done at 35 and 49 days old. At the end of the experimental period (7 weeks old), liver and bursa of Fabricius were removed after slaughter for histological examination. Results show no significant differences in feed conversion ratio and dressing percentage in both times. Weekly body weight of sodium nitrate group was significantly decreased at (p≤0.05) in the sixth and seventh weeks. A rate of liver weights and antibody titers of the second sets significantly decreased (p≤0.05) comparing with the control group at the 35 days test. The levels antibody titers, AST and ALT of sodium nitrate group are significantly higher in 49 days old broiler chickens comparing with the 35 days old. On the other hand, ALT of the second sets is significantly higher (p>0.05) comparing with the control group at the 49 days test. Sodium Nitrate led to numerous histological lesions in liver and bursa of Fabricius in 49 days old broiler chickens. In brief, Sodium nitrate consumption has a negative correlation with body weights, liver enzymes, and histological change.

Abstract

In the current study, fifteen rabbits from both sexes have been used to identify the anatomical and histological structure of abdominal aorta. Ten rabbits used for anatomical study. The celiac artery was a first branch of the abdominal aorta (A.A.) and then followed by the cranial mesenteric artery, right and left renal arteries, lumbar artery, caudal mesenteric artery and finally, it gives off two common iliac trunks. The splenic artery was the larger branch of the celiac artery and the cranial mesenteric artery was the greater branches of A.A. of rabbits. The lumber branches were very clear and a raised from the ventral aspect of A.A. There were numerous of jujenal arteries arises from a cranial mesenteric artery and the testicular or ovarian arteries sometimes originated above or below caudal mesenteric artery. Five rabbits used for a histological study of the abdominal aorta of three regions at the (celiac artery. renal artery. and common iliac artery). The abdominal aorta has consisted of three layers from internal to external tunica intima, T. media, and T. adventitia. The intima consists of a single layer of endothelial cells and it's the thinnest layer while T. media composed of numerous elastic laminae in a circular arrangement and it's the thickest layer finally T. adventitia was the outermost layer consist of smooth muscle fibers, collagen fibers, few elastic fibers, and vasa vasorum. The aim of this study to exposure the normal appearance of abdominal aorta by used the using corrosion cast & latex techniques and histological studies.

Abstract

An experiment was carried out in the College of Veterinary Medicine; the University of Baghdad to investigate the effect of feeding formaldehyde treated meal on body weight gain, rumen fermentation, and some blood traits in local lambs. Twenty four lambs with body weight ranged from 20 to 23 kg and aged about 3 to 4 months were selected and divided randomly into two groups of twelve each (body weight was considered). These animals fed daily concentrate diet (3% of their body weight) and 0.5 kg of alfalfa hay, in addition to freely, graze for 2-3 hours/ day. Results showed highly (p ≤ 0.05) a significant difference in the body weight gain (24.12 ± 1.01 kg) and weight of wool fleece, testis (298.00± 23.09 g) and kidneys (195.00± 8.66 g) between groups of lambs fed bypass protein compared with control group. Also, animals fed treated meal had higher (p ≤ 0.05) significantly in the meat content of crude protein (17.42 ±0.31), digestibility(57.19 ± 2.58 ) and alkaline phosphatase enzyme(ALP) compared with control group, while there are no differences in amino acids in the meat between groups of lambs. The results showed significant differences appeared in serum total protein and blood urea. In addition, no significant differences appeared in rumen fermentation parameters except rumen Ammonia-N. In conclusions: the bypass proteins technology may improve the production performance in local lambs. Therefore the bypass meal can be added to the diet of lambs for fattening. It had a positive effect on growth and fat composition of meat.

Abstract

Burn wound infections are one of the most important impairments that occur in the acute period following injury and colonization by the pathogenic agents, including gram-positive, gram-negative bacteria and yeasts. The study included 210 clinical swab samples have been collected from burn- wound patients and cultured on blood agar, MacConkey agar and Eosin methylene blue agar, the period from 1/3/2016 to 30/8/2016 at different hospitals in Baghdad city. By microscopic characterizations, morphological and biochemical reactions, the results showed that 42 (37.5 %) isolates belong to Klebsiella pneumoniae. The analysis of (10) clinical origin of Klebsiella pneumoniae isolates by multilocus sequence typing show the relationship between the local and global isolates which belonged to 7 housekeeping genes (rpoB;beta-subunit of RNA polymerase, gapA; glyceraldehyde 3-phosphate dehydrogenase, mdh; malate dehydrogenase, pgi; phosphoglucose isomerase, phoE; phosphorine E, infB; translation initiation factor 2, tonB; periplasmic energy transducer). The present study the results showed the 10 isolates of K. pneumoniae were identified into different sequence type (ST): ST 14 and 15 for (IQK1, IQK2, IQK3, IQK4, IQK5, IQK6 and IQK7), ST 266, 54, 709, 728 and 1177 for (IQK8 and IQK9) and ST 665, 975 and 2149 for (IQK10). In addition, the result showed 100% identities with previously reported genes. There was no information on the sequence type (ST) (an allelic profile) of K. pneumoniae in Iraq. According to the results of the present study, the most occurrence clones found in Baghdad hospitals were endemic ST14 and 15, which accounted for 70% of the isolates (n=10). The presence of the ST14 and 15 clones in Iraq which came closer to global (14 and 15 STs) clones might be indicating intercontinental transmission because these clones were added to the list of the strains that isolated from different countries.

Abstract

The present study was undertaken to charge the microbial consignment of uncooked meat samples collected from the slaughtered animals of Basrah abattoir. In this study fifty raw meat samples (25 meat Cow and 25 meat Sheep). In the present study, the pathogenic bacteria were identified as Enterococcus faecalis and Clostridium perfringens by 16S rDNA. This has a specific suggestion beginning the Public Health point of sight. The result designates considerable attendance of microbial contaminants in the meat where a shortage of correct hygiene in the slaughtered. The specimen (2) were diagnosed by amplifying universal primer of 16SrDNA. Sequence information is analyzed by (NCBI) program. Sequence results showed the dominance of Enterococcus faecalis and Clostridium perfringens.

Abstract

Anaplasma ovis is a one of an important group of the tick-borne pathogen and an obligate intraerythrocytic bacterium, which infects sheep and goats as well as wild ruminants. The phylogenetic study of A. ovis in small ruminants has not studied yet in Iraq. In this study, the presence of A. ovis was investigated in a total of 80 (40 sheep and 40 goats) obtained from 16 randomly selected small ruminants flocks in AL-Qadisiyah in Iraq. All blood samples tested microscopically, firstly by Diff-quick stained blood smear for the detection of intraerythrocytic pathogens. Total DNA was extracted from a sample and submitted to PCR based on fragment amplified of 16S rRNA gene followed nucleotide sequencing and phylogenetic analysis. Six out of 80 samples, (10%) from sheep and (5%) from goats gave positive results. The results of nucleotides sequencing and multiple alignments revealed related Iraqi isolates had a high identity (99.70% - 97.21%) with isolates of other countries, the phylogenetic analysis demonstrated that Iraqi isolates of A. ovis fell one clade near to Russian and Sweden strains and shared 99.7 %-98.36 % with them. In conclusions: this work indicates to detect A. ovis at a low rate in sheep and goat in Iraq and it had a high genetic similarity to world strains.

Abstract

This study was conducted to determine the adverse effects of high temperature on some blood parameter of broiler chickens reared under high environmental temperature and evaluating the adding of (propolis and/or digestarom) on diet, three hundred, one-day-old broiler chicks (Rose 308) were distributed equally in to two separated room, thermoneutral (TN) groups and heat stressed (HS) group ( 33 ± 2°C)all over the experiment (42)day. These groups subdivided into five treated groups (30) chick each. They offered a basal diet supplemented with either propolis (2g/kg of diet), or digestarom (150mg/kg), or a mixture of(propolis 2g/kg +digestarom 150mg/kg) or without any diet supplementation with a vaccine or without any diet supplementation without the vaccine. Alanine Transaminase (ALT), Aspartate Aminotransferase (AST), Total Protein and albumin levels were estimated using commercial kits. The result revealed that dietary supplementation with propolis and /or digestarom caused significantly (P≤0.05) increases in blood plasma levels of total protein, globulin, levels of albumin, and significantly reduce (P≤0.05)ALT and AST with or without heat stress as compared to their control groups, while there was a significant reduction in levels of total protein, albumin, globulin (P≤0.05), and significant increase(P≤0.05 in level of AST and ALT. It's concluded that providing broiler’s diets with propolis alone or in combination with digestarom are effective in reducing the adverse effects of heat stress in broilers especially the mixture of propolis with digestarom, which gave the best result.

Abstract

One hundred samples of raw cow milk was collected from different market centers in Basrah city during a period from 16 June to 21 August 2017 and analyzed for the presence of Staphylococcus aureus. The biochemical test revealed that 26 isolates on mannitol salt agar were (S. epidermidis), and 32 isolates were (S. aureus) and give a positive result to coagulase, catalase urease, and citrate utilization tests, whereas negative results to indole test. The high rate of S. aureus was observed in Abu Skair 55% followed by Al-Dair 40%, Al-Zubair 35%, Al Karma 25%, and Al-Hartha 5%. The presence of the mecA gene by using pairs of primers revealed that 6.25% of S. aureus strain contain that gene. By using the disc diffusion method, all tested isolates revealed high sensitivity toward chloramphenicol and erythromycin, intermediate sensitivity to tetracycline and novobiocin, and 100% resistance toward methicillin and amoxicillin.

Abstract

Subacute ruminal acidosis'(SARA) is a common health and productions problem in dairy cattle and described as repeated incidences of drop pH. of the rumen. The aim of the study was to estimate the lipopolysaccharide concentration in the content of ruminal fluid and feces of dairy cows as a diagnostic tool for subacute ruminal acidosis. Four hundred and twenty- seven cows examined in this study in Al-Qadisiyah Province, from these cows, Ninety lactating cows, were have affected with subacute ruminal acidosis. Moreover, fifty healthy lactating cows were considered as a control. Both diseased and control cows were exposed to additional tests of ruminal fluid and fecal samples. The difference observed in the lipopolysaccharide (LPS) concentration in the ruminal fluid and fecal samples 97.772 and 108.823 Eu/ml respectively, of SARA group which were significantly (P≤0.05) higher than the control group. The ruminal and fecal LPS can be used as diagnostic tools to identify the SARA.

Abstract

Asparaginase (ASNase) treatment results in the synthesis of some factors such as activating-transcription-factor-4 (ATF4). The eIF2-ATF4 pathway is essential for cell survival during amino acid starvation conditions. This requires the eukaryotic-initiation-factor-2 (eIF2) kinase called general control nonderepressible 2 kinase (GCN2). Our objective and hypothesis are addressed in our aim to describe the liver response to ASNase in mice deleted for Gcn2 and Atf4 and either treated with phosphate buffered saline (PBS) or asparaginase (ASNase) for 8 days. We found that deletion of Gcn2 and/ or Atf4 affect body weight and fat and lean content. The results showed that Atf4-/- mice had significantly less fat mass than WT and Gcn2-/- mice even before the startup of the study. Also, WT mice experienced minimal change in body weight and body composition, but Atf4-/- and Gcn2-/- mice both lost substantial amounts of body weight and body fat without altering lean mass. Moreover, Gcn2-/- mice showed high significant increment in liver and pancreas weight when treated with ASNase compared to the other groups. Lastly, spleen weight was significantly lower in all treated groups, except Atf4 null mice, compared to their own control groups. In conclusion, this research provides insight into the importance of the genetic background of patients in choosing ASNase as a treatment.
