ABSTRACT
Objective: To determine the presence of antibodies against phase II among slaughterhouse workers in Kerman, southeast of Iran.Methods:sorbent assay using phase II Coxiella burnetii as the antigen [kit (Virion\Serion, Wurzburg, Germany) according to the manufacturer’s protocol].Results:The antibody titers of the serum samples were measured by enzyme-linked immuno Conclusions: Our findings suggest that slaughterhouse workers in Kerman area have a higher risk of infection and should consider potential infection with Coxiella burnetii. The positive rate of IgG antibody was 68% in the slaughterhouse workers.
ABSTRACT
Objective: To describe the seroprevalence rate of bluetongue virus (BTV) in goat flocks in southeast of Iran.Methods:93 sera samples were collected between 2011 and 2012. Antibodies to BTV in sera were detected by using a commercial competitive ELISA 3 according to manufacturer’s instructions. The blood samples were collected randomly from herds of southeast of Iran. A total of Results: The seroprevalence rates were 67.7% for goats. Within a herd, prevalence of BTV seropositive animals ranged from 33.3% to 100.0%. All goat flocks were positive to BTV antibodies.Conclusions:This study describes a high seroprevalence rate of BTV in goat flocks in southeast of Iran for the first time.
ABSTRACT
Objective:To evaluate serological findings of bovine leptospirosis which is a zoonotic disease with worldwide distribution caused by Leptospira interrogans. Methods: One hundred and sixty seven sera were collected from 9 commercial dairy herds in jiroft suburbs, from July to October 2011. Microscopic agglutination test (MAT) was used to evaluates serological findings of bovine leptospirosis in Jiroft suburb dairy farms, Kerman province, Iran. Results:Antibodies were found by MAT at least against one serovar of Leptospira interrogans in 29 samples (17.36%) among 167 sera at a dilution 1:100 or higher, and Leptospira pomona was the most prevalent serovar. Positive titers against more than one serovar were detected in 6 sera of the positive samples. Conclusion:This study is the first report of leptospirosis in Southeast Iran and showed that Leptospira pomona was the most and Leptospira icterohaemorrhagiae the least prevalent serovars in Southeast Iran.
ABSTRACT
Staphylococcus aureus [SA] may cause infection in all body organs. Many personnel and patients in hospitals may become carriers of this species. The aim of this study was to investigate relative frequency of SA and its resistance to Methicillin. A couple of swabs were taken from nose and nails of 151 personnels working in operation room of Shahid Sadoughi Hospital in Yazd. Samples were inoculated into Mannitol salt agar medium and S. aureus colonies were antibiogramed to determine the rate of resistance to methicillin. Statistical analyses were performed by chi-square and Fishers' exact test. Overall prevalence of SA was 35.09%[19.2% and 15.9% in noses and nails, respectively]. Prevalence of methicillin-resistant SA [MRSA] was 11.92%[5.3% and 6.6% in noses and nails, respectively]. Surgeons had the highest, and workers the lowest prevalence of nasal SA carrier rate. In contrast, the nails of servants had the highest, and surgeons the lowest SA carrier rate. No significant difference was found between carrier rate and age, sex and duration of employment. But a meaningful relation was found between type of job and MRSA in both noses and nails. All of the MRSA isolates were sensitive to vancomycin. Since employees of operation room are continuously working with patients undergone operation, screening both the personnel and patients to determine the rate of carriage, preventing transfusions of fore mentioned bacterium is necessary and highly recommended

Objective: Bluetongue virus is an arthropod-borne Orbivirus in the family Reoviridae which infects both domestic and wild ruminants. Bluetongue disease is a List A disease of the Office of International Epizootics. To the best of our knowledge, no report has been published on bluetongue disease of sheep flocks of Southeast of Iran. The objective of this study was to describe the seroprevalence rates of BTV in sheep flocks in southeast of Iran. Methods: The blood samples were collected randomly from herds of Southeast of Iran. A total of 188 sera samples (94 male, 94 female) collected between 2009 and 2010, were available. Antibodies to BTV in sera were detected by using a commercial competitive ELISA (Institute Pourquier, Montpellier, France) according to manufacturer’s instructions. Results: The seroprevalence rates were 6.57 %for sheep herds. Within a herd, prevalence of BTV seropositive animals ranged from 0% to 42.85%. 33.3% sheep flocks were positive to BTV antibodies. Sex didn't affect the rate of seropositivity, but the rate of seropositivity was significantly changed in different age groups. Conclusion: This study describes the seroprevalence rates of Bluetongue virus (BTV) in sheep flocks in southeast of Iran for the first time.
ABSTRACT
Group B streptococcus[GBS][Streptococcus agalactiae] is the leading cause of morbidity and mortality of the newborn infant and accounted as a factor leading septicemia after birth in mothers. Infections in infants are usually acquired by contact with the genital tract of the mother during labor and delivery. So a rapid screening test for group B streptococcus that could accurately identify pregnant women who are carrying the bacteria at the time of delivery would obviate the need for prenatal screening.The goal of this study was molecular epidemiology of group B beta Hemolytic Streptococcal[GBS] colonization in the vaginal flora of pregnant women. Samples were taken from mucus of anal and vaginal of 250 pregnant women during 35-37 week's ingestion by swap. Samples were tested by standard culture using Todd Hewitt Broth and Blood Agar and also by PCR using cfb gene. Culture identified 21[8.4%] women as carriage of GBS from 250 women but PCR assay could identify 24[9/6%] women. In comparison to culture results, sensitivity, NPV Specificity PPV of PCR Were[100%, 100% and 97%, 82%] respectively. The times that used for PCR assay and culture were 2h and 36h respectively. In conclusion, we found that group B streptococci can be detected rapidly and reliably by a PCR assay of combined vaginal and anal secretions from pregnant women at the time of delivery. Also this study shows that incidence of GBS is at high rate in Iranian pregnant woman, so we recommend screening of pregnant woman for detecting of GBS emphatically
