Saleh K. Majeed | Abbas A. Khadhair
The current study was conducted at the college of veterinary medicine, university of basrah in the periods extended from 22/10/2016 to 22/1/2017. The present study is designed to report the toxic effects of digoxin on kidney histologically and biochemically by measuring kidney parameters urea and creatinine level in the serum. Maximum toxic dose determined by using 2 rats dosed orally until clinical signs of toxicity became prominent at 30mg for each rat and considered as MTD. The chronic toxicity study was carried out on 48 adult rats divided into 4 groups. Control (G1) receive distilled water, Low dose (G2) dosed with 1/20 MTD(1.5mg/kg) digoxin, Intermediate dose (G3) dosed with 1/10 MTD(3mg/kg) digoxin and High dose (G4) dosed with 1/5 MTD(6mg/kg) digoxin by oral gavage for 90 days. At the end of experiments all animals were sacrificed and blood sample were collected for estimation of biochemical parameters of rat. Result reveals histopathological changes presented as dilation/vaccuolation of renal tubules and atrophy of glomeruli. There is a significant (P≤0.05) increase in serum urea and creatinine level in high dose (G4) group when compared with other study group. We conclude that high dose digoxin has toxic effect on renal tissue and lead to their damage.

This study was conducted to identify the erythromycin resistance genes in the coagulase-negative staphylococci (CoNS) and its molecular characterization after isolating the bacteria from the samples of domestic animals and their products during the period from September 2016 to March 2017 from different areas in Basra city. 200 samples were collected from animals including: 40 samples from meat, 50 samples from raw milk, 30 samples from treated milk, 40 samples from cow's nasal swabs and 40 samples from cow's teat swabs. Results showed that from 200 collected samples only 108 were CoNS distributed in 22(15.1%), 18(12.4%),10(6.8%), 26(17.9%),32(22%), from meat, raw milk, treated milk, nasal swabs and teat swabs respectively. Samples were planted on the selecting mannitol salt medium to isolate Staphylococcus spp. which had the ability to grow on the mentioned medium. When the coagulation test was performed, some isolates were not able to produce the coagulation enzyme, and the results showed that 108 isolates were coagulase negative (54%). Twenty-two isolates of minced meat 55%, 18 isolates of cow's milk (36%), 10 isolates of milk sold (33%), 26 isolates of the nose of the animal (65%) and 32 isolates of animal teat swabs (80%). Twenty-five isolates of these negative staphylococci were identified using VITEK 2 kit. The result showed that 10(40%) isolates identified as coagulase negative Staphylococcus and fall in87 four species including 4 (40%) Staphylococcus lentus, 4 (40%) Staphylococcus gallinarum, 1 (10%) Staphylococcus haemolyticus, and 1 (10%) Staphylococcus chromogen. When the ermA, ermB, ermC and msrA genes were investigated by PCR the result showed that they contain the genes in a percentage 5%, 20%, 20% and 5% respectively. By using the multiplex PCR molecular weight technique (ermA, ermC) and (msrA, ermC), the ratio of both genes was 15% and 5% respectively.

Brucellosis an intracellular pathogen capable of infecting animals and humans. The aim of this study was to identify Brucella spp in apparently healthy cow and goat raw milk samples by a polymerase chain reaction (PCR)-based method. A total of 75 cow milk samples(55 direct and 20 indirect) and 50 goat milk samples were examined by PCR. To establish a PCR protocol for diagnosis of brucellosis, DNA was extracted from the milk samples by using a commercial kit. PCR amplification was done for detection of Brucella DNA using BCSP31 target gene and IS711 locus. The PCR assay showed that an amplicon of 223 bp was obtained in 28% (21/75) and 8% (4/50) samples of cow and goat tested milk using primers (B4/B5) derived from aBCSP31gene encoding the 31-kDa Brucella abortus antigen. In another PCR, an amplicon of 498 bp was obtained in 100% (21/21) of the brucella genus BCSP31-PCR positive cow milk samples using Brucella abortus-specific primers derived from a locus adjacent to the 3’-end of IS711, and also an amplicon of 731 bp was produced in 100% (8/8) of the BCSP31-PCR positive goat milk samples using Brucella melitensis-specific primers.PCR positive results for brucella genus and brucella abortus species were observed in all (100%) cow,s milk samples(n=11) with clinical history of abortion.As a single PCR product, no B. abortus was detected in goat milk samples alsoB. Melitensis was not detected in cow milk samples

Polysaccharide was extracted from the leaves of (Molokhia) Jew’s-mallow by hotwater extraction using trichloro acetic acid(TCA) to removal of protein from the polysaccharide ,precipitation with ethanol, and obtained a polysaccharide yield from 4.2% based on wet weight source. The biochemical composition of the polysaccharide contains total carbohydrate,sulfateandprotein77.6%, 8.6%, 0.63%, respectively. Phytochemical tests were carried out for polysaccharide. The previous studies indicated the presence of glycoside, phenol and tannin in polysaccharide from Jew’smallow. However, the presence of both alkaloids and saponins was not observed .The Fourier transform infrared (FTIR) spectral analysis of the polysaccharides consist of carboxyls and sulfate groups.The anticoagulant activity of polysaccharide was evaluated by activated partial thromboplastin time (APTT) and prothrombin time (PT) assays with respect to heparin The results obtained by APTT assay, through the increase in coagulation time, the increase in blood coagulation time with increased polysaccharide concentration, the 100 μg/ml polysaccharide concentration had the longest time of 210Sce and was compatible with the concentration of1000 (IU/ ml) of heparin.However the time of PT did not have any apparent effectiveness in increasing the time of coagulation at all concentration compared with heparin.
