BACKGROUND: The H9N2 subtype of avian influenzaviruses (AIVs) has been isolated in multiple avian species inmany European, Asian, African and American countries. Sincethe first outbreak of H9N2 virus in Iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. Several amino acids in thevirus ribonucleoprotein (RNP) complex including the nucleoprotein(NP) and polymerase (PB2, PB1 and PA) proteins areassociated with host range and virulence. OBJECTIVES: Our aimwas to understand the molecular characterization of RNPcomplex proteins of Iranian H9N2 subtype isolates. METHODS:The full length nucleotide sequences of RNP complex genes oftwo strains designated as Ck/IR/ZMT-101/98 and Ck/IR/EBGV-88/10 were amplified and sequenced. RESULTS: The phylogeneticanalysis revealed that both strains were located indifferent sub-lineages. However, based on the genetic similarities,PB1, PAand NP genes of Ck/IR/EBGV-88/10 strain had aclose relationship with a H7N3 subtype strain, isolated fromPakistan. Most positions of RNP proteins contained amino acidstypical of avian determinants of host range. The results showedthat the Iranian RNP complex genes have undergone geneticreassortment. CONCLUSIONS: Continuous AIV monitoring inpoultry industry would help to obtain more information aboutgenetic variation of H9N2 viruses and possible emergence ofvirulent and/or pandemic viruses.

BACKGROUND:The bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. OBJECTIVES:The aim of this research was to investigate the bacterialcontamination status, with emphasis on Escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated Escherichia coli. METHODS:Atotal of 120 ostrich eggswith dead embryos, at weekly intervals, were collected fromthree ostrich hatcheries. The dead embryos were sent tolaboratory and samples were collected aseptically from differentorgans. Bacterial detection and identification were performed byusing standard bacteriological and biochemical techniques.Antimicrobial susceptibility test was carried out by agar diskdiffusionmethod against 27 antimicrobial agents. RESULTS:Different types of bacteria were isolated from 56 eggs (46.7%).Twenty-four ostrich eggs were shown to carry E. coli. In someeggs, in addition to yolk sac, E. coli was also isolated frommeconium, liver, or heart blood which increased the total numberof E. coli isolates to 32. All E. coli isolates were susceptible totrimethoprim + sulphamethoxazole, danofloxacin, and flumequine,whereas all were resistant to carbenicillin and erythromycin.Resistance to other agents was variable. Multi-drugresistance pattern was found among all E. coli isolates andincluded 2 to 12 drugs. Thirty-two E. coli isolates generated 30different resistance profiles against 27 antimicrobial drugs.CONCLUSIONS: This was the first comprehensive reportregarding the bacterial, particularly Escherichia coli, contaminationof dead-in-shell ostrich embryos and antimicrobial resistancestatus of the Escherichia coli isolates from ostrich eggs inIran.

BACKGROUND: Leptospirosis is a worldwide zoonosis causedby Leptospira interrogans. Leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. OBJECTIVES:The aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous records of leptospirosis in Tehransuburbs in 2011-2012. METHODS: For the purpose of this study,408 blood samples from dairy cattle and 154 blood samples fromfeedlots were collected using sterile 10ml venoject vacutainersfrom tail vein. Two months later, 118 urine samples werecollected from 20% of the two groups of serological negative andpositive animals. All serum samples were serologically tested bymicroscopic agglutination test (MAT), a standard method forserological diagnosis of leptospirosis. The serum samples weretested for antibodies against five live antigens of Leptospirainterrogans serovars: Pomona, Grippotyphosa, Hardjo, Icterohaemorrhagiaeand Canicola. Urine samples were used forbacteriological isolation of Leptospira spp. RESULTS: Serologicalresults showed that 228 (40.6%) of animals had a positivereaction against one or more serovars. The most prevalentLeptospira serovars was Pomona 118 (40.3%) and the leastprevalent was Canicola 4 (1.4%). The most prevalent titer was1:100, and the highest titer was 1:1600. Also the mostseropositive cases were observed in 3 to 4-year-old cows.Bacteriological results revealed that in 11 (9.3%) urine samplesLeptospira spp. were isolated, all taken from one feedlot farm.According to the history taken from each farm, the main riskfactors were the presence of rodents and low hygienic conditionsof the farms. CONCLUSIONS: The results of this study revealedthat cows could have a major role in maintaining Pomona,Grippotyphosa and Hardjo serovars; indeed, they are a potentialzoonotic risk to slaughter house workers, meat inspectors,milkers and farmers.

BACKGROUND: West Nile virus (WNV) is a vector-borneagent that is maintained within a bird-mosquito cycle. In humansand equids, infection by this agent is usually asymptomatic, orcharacterized by a mild febrile illness. However, fatal meningoencephalitisor encephalitis may occur. OBJECTIVES:The aim ofthis study was to evaluate the prevalence of WNVinfection andcorrelation of this organism with host and environmentaldeterminants in horses in Khuzestan province. METHODS: In2011-2012, serum samples of 155 horses were randomly collectedfrom 7 zones of Khuzestan province and were examined byELISAassay. RESULTS: Seroprevalence of WNVinfection was70.3% (95% CI: 63.1-77.5%). Statistical analysis showed thatage, zone, presence of lake, type of bed, time of sampling, stayingout of the stable after sunset and the method of insect control aresignificantly associated with infection (p<0.05) but sex, presenceof river, wall condition, presence of rubbish dump and history ofdisease are not significantly associated with infection (p>0.05).CONCLUSIONS: The results of the present study confirm that theWNV infection exists in Khuzestan province. Considering thelocal weather conditions and the facility of vector-bornetransmission, the health authorities should take measures toprevent and control the infection.

BACKGROUND: Stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal Mesenchymal Stem Cells (MSCs) have beencarried out. On the other hand, Cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. OBJECTIVES: The aim of this study was toisolate, characterize, and transduce cBM-MSCs. METHODS:Canine Bone Marrow-derived Mesenchymal Stem Cells (cBMMSCs)were isolated from bone marrow of dogs andcharacterized based on morphology, differentiation capacities,and surface marker expressions. For the first time, we labeledcBM-MSCs by GFP-encoding lentiviral vector to track them.RESULTS: cBM-MSCs were successfully isolated and proliferated.Morphologically, these cells were similar to otherMSCs from other sources and species and were able todifferentiate into osteocytes and adipocytes. cBM-MSCsexpressed surface marker CD44 but were not able to expressCD34. Approximately, 70% of cells efficaciously expressedGFPafter labeling; CONCLUSIONS:We found that GFP labelingis an easy and effective technique to track transplanted cBMMSCs.Our results also provide fundamental information aboutcanine BM-MSCs in order to use in veterinary medicine.

BACKGROUND: Information regarding serum biochemicalprofile can reflect cardiovascular performance in animals.Although studies have evaluated the inter-relationship amongcardiovascular biomarkers in animals and human beings, thereare no reports of such a probable relationship in camelids.OBJECTIVES: The aim of the present study was to provide dataon the correlations among cardiovascular biomarkers indifferent ages of clinically healthy male dromedary camels toprovide a basis for assessing cardiac muscle healthiness in thisspecies. METHODS: Thirty clinically healthy dromedary camels(Camelus dromedarius) were selected and divided into four agegroups including 1-3 (n=7), 4-6 (n=7), 7-9 (n=8), and above 10(n=8) years old. Blood samples were collected and sera wereseparated. Serum concentrations of homocysteine (Hcy),cardiac troponin I (cTnI), creatine kinase-myocardial specificisoenzymes (CK-MB), lactate dehydrogenase (LDH), alanineaminotransferase (ALT) and aspartate aminotransferase (AST)were evaluated. RESULTS: The results of the present studyshowed that there were significant correlations among cTnI andCK-MB (r=-0.853; p=0.015) and Hcy (r=0.916; p=0.004) in the4 to 6-years-old group of clinically healthy male dromedarycamels. LDH was significantly correlated with CK-MB in the 7to 9-year-old group (r=-0.710; p=0.045). There were nosignificant correlations among different factors of 1-3 and above10-year-old groups (p>0.05). CONCLUSIONS:The data providedhere is the first report on cardiac health assessment parameters indromedary camels. Moreover, the data is valuable in camelracing clubs, when an overall cardiac health and fitness is to beassessed. The correlation reported here might also be helpful foreasier analysis of cardiac health status in dromedary camels. Thedata may be useful for assessing suspected cases of myocardialdiseases and its changes maybe of prognostic value.

BACKGROUND:Uncontrolled application of diazinon (DZN)can cause environmental contamination and adverse healtheffects on humans or animals. OBJECTIVES:This study aimed toinvestigate the toxic effects and the level of DZN in serum andtissues of rabbits following a sub acute dermal exposure totoxicant. METHODS:Different doses of DZN were applied dailyto New Zealand rabbits through the ear skin in incremental dosesfor 4 weeks. Blood samples were collected at the beginning andthe end of each dose-week period. Tissue samples were collectedfrom brain, muscle, kidney and liver on day 28, after euthanizingthe rabbits. DZN contents of the blood and tissue samples weremeasured using a reversed phase HPLC system. RESULTS:Clinical observations indicated signs of toxicity in the animalsexposed to DZN as shown by diarrhea and body weight loss fromday twenty. The level of DZN in the blood elevated withenhancing exposure time and reached the highest level at the endof the fourth week (0.620±0.26ppm). The highest level of DZNwas found in the brain tissue (0341±0.015 ppm). CONCLUSIONS:The results of this study revealed the tissue accumulation andsubsequent toxic effects of DZN following the subacute dermalexposure to the toxicant. It suggests that the determination of thetoxicant level in the serum or tissue can be a monitoring methodfor the detection of the contamination rate.

First report on Anaplasma platys infection in a dog in the Philippines
Adrian
Ybanez
Anaplasma platys, previously known as Ehrlichia platys,which causes infectious canine cyclic thrombocytopenia, has notbeen extensively studied in Southeast Asia. Recent reports in theregion have been limited to ticks and dogs in Thailand, and toticks in the Philippines. In this report, DNAfragments of A. platyswere molecularly detected in a dog in the Philippines. Apitbullpuppy exhibited pancytopenia (WBC: 3.5 x103/μL, PCV:11.5%, RBC: 1.2 x106/μL, HGB: 3.7 g/dL, platelet count: 24x103/μL), hepatitis, elevated alanine amino transferase (127u/L), and splenomegaly. Inclusion bodies in the platelets werealso seen in the blood smears of this case. A. platys sequencesobtained in the present study revealed 100% homology with A.platys previously detected in a Rhipicephalus sanguineus tick inthe country. This study documents the first reported case of A.platys infection in dogs in the Philippines, and adds knowledgeto the current vector-borne disease epidemiology in SoutheastAsia.
