Species distribution, genetic diversity and antimicrobial susceptibility of Campylobacter isolates recovered from the preputial cavity of healthy rams in Turkey

AIMS

Campylobacter sp. are important causes of reproductive disease in ruminants worldwide. Although healthy bulls are well-known carriers for infection of cows, the role of rams as a potential source for infecting ewes is unclear. This study aimed to determine prevalence, species distribution, genetic diversity and antimicrobial susceptibility profiles of Campylobacter sp. isolated from the preputial cavity of healthy rams.

METHODS AND RESULTS

The material of this prospective study comprised 191 swab samples taken from the preputial cavity of healthy rams. Enrichment and membrane filtration were employed for the isolation of Campylobacter. Presumptive isolates were confirmed as Campylobacter by phenotypic and molecular tests. 16S rRNA gene sequence analysis was used for the definitive identification of the isolates at species level, and genotyping was performed using pulsed-field gel electrophoresis (PFGE). The susceptibility of the Campylobacter sp. isolates to various antibiotics was determined by the disk diffusion test. In all, 27 of the 191 (14·13%) swab samples were found to be positive for Campylobacter sp. (28 isolates were recovered in total). Per phenotypic and genotypic analyses, one isolate was identified as Campylobacter mucosalis and the remaining 27 isolates were identified as Campylobacter sputorum bv. faecalis. The PFGE analysis of the C. sputorum biovar faecalis isolates produced 17 clusters and 24 different pulsotypes, indicating high genetic heterogeneity. All 28 isolates were found to be susceptible to all of the antibiotics tested.

CONCLUSIONS

Healthy rams may be an important reservoir of different Campylobacter species in the preputium.

SIGNIFICANCE AND IMPACT OF THE STUDY

This study demonstrated for the first time that healthy rams can carry different Campylobacter sp. including genetically diverse C. sputorum bv. faecalis and C. mucosalis in the preputial cavity. Further investigation on the potential implication of this finding on sheep reproductive health (e.g. infectious infertility, and abortion) and overall epidemiology of Campylobacter may be warranted.

Fertility characteristics and related factors impacting on Syrian refugee women living in Istanbul

BACKGROUND

Women's fertility characteristics are affected by many different factors.

AIM

To gain an awareness of fertility characteristics of Syrian refugee women and the influential factors.

METHODS

This study was planned as a cross-sectional study to determine the efficiency and related factors of Syrian refugees living in Istanbul. The survey of 300 refugee women applying Arabs who migrated to Turkey, Kurds, Turkmen and Yezidi origin they receive.

RESULT

Average age of the women studied was 34.26 ± 10.15, 34.6% of the participants had not received any education, 37% had less than two-year inter-pregnancy interval, 58.6% have not received "Safe Motherhood" service, 43.6% have conceived their last child unwillingly. Women in the study group had in average 3±2,4 children and the number of children they wanted was 3±1,59. These values were substantially affected negatively by the women's education level and positively by the income level. Yezidis had significantly more children than other ethnic groups and did not have a "religious ban" on voluntary abortion.

CONCLUSION

It has been noted that fertility characteristics of refugee women who migrated to Turkey changed according to their ethnic backgrounds and were sustained in the country they migrated to. Along with harsh living conditions and insufficient access to health services the situation has been observed to pose serious risks on reproductive health.

Perosomus elumbis in a Holstein calf infected with bovine viral diarrhea virus

The detection of bovine viral diarrhea virus (BVDV) in a female Holstein calf presented with perosomus elumbis, a congenital anomaly, is reported here. A cow with dystocia was evaluated and an abnormal dead calf was detected during vaginal examination. The calf was retrieved via caesarean section and exhibited abnormalities characteristic of PE, such as vertebral and pelvic malformations. These abnormalities were further confirmed using radiographic and necropsy examinations. At necropsy cerebellar hypoplasia was an additional finding, which is a typical lesion associated with bovine virus diarrhea (BVD). Several tissue samples from the calf were tested for the presence of antigens of BVDV and bovine herpesvirus-1 (BHV-1) by ELISA. In addition, sera samples from the dam and calf were tested for the presence of antibodies against BVDV, BHV-1, and bluetongue disease virus (BTV) using a virus neutralization assay. Results indicated that the calf was congenitally infected with BVDV, whereas there was no evidence for the presence of BHV-1 and BTV. In the dam’s serum no antibodies against BVDV, BHV-1, and BTV were detected. Even though the etiology of perosomus elumbis is unknown, BVDV, which causes fetal anomalies at early gestation in cows, may have been a contributing factor in this case.

Sliding hernias in female children

INTRODUCTION

Articles published in the English language report that 15-20% of the inguinal hernias in female children are sliding hernias. These studies do not specify the age at moment of surgery, neither the age distribution of sliding hernia. We retrospectively evaluated inguinal canal pathologies to answer these questions.

MATERIAL AND METHOD

We retrospectively evaluated the records of the patients operated on at the Pediatric Surgery Clinics of the Ordu, Usak and Denizli State Hospitals and the Afyon Obstetrics and Gynecology Hospital.

RESULTS

A total of 3105 cases had been operated on for an inguinal hernia between January 2008 and December 2010 and 673 (21.6%) were female. The most common age at surgery was between 0 and 1 years (26.5%). A sliding hernia was found in 22.4% (n = 151) of all cases. The sliding hernia rate was 45.8 (n = 82) and 14.9% (n = 69) in children younger and older than 1 year of age respectively (p < 0.05). The most frequently sliding organ in both groups was the ovary, followed by the fallopian tubes.

CONCLUSION

A sliding hernia is more common in female children under the age of 1 year and surgical treatment should be planned within a short period once the diagnosis is made. In addition, this recent statistical value for subjects aged 0 to 1 year and over 1 year can be used in new clinical studies.

Supporting safe motherhood services in Diyarbakir: a community-based distribution project

To provide pregnant and puerperal women experiencing problems with receiving health care in Diyarbakir, Turkey, with an education program and counseling to help them attain appropriate health behaviors and to support receiving health care through a community based distribution model. This article is a descriptive report of a qualitative community based distribution project conducted in cooperation with the Women's Research and Implementation Centre (WRIC) of Diyarbakir Metropolitan Municipality (DMM) and Turkish Family Health and Planning Foundation. The study was carried out between March 2007 and April 2008 in six districts of Diyarbakir, a region with a population of 37,000 people of low socio-economic status and who immigrated from the surrounding villages. A total of 6,029 families were visited and 1,119 pregnant and puerperal women were contacted, provided with education and counseling and referred to primary health care clinics at home visits. Seven women living in the region were selected and educated so that they could offer peer education and educational material was prepared for the target group. The pregnant and puerperal women living in the study area were recorded and referred to primary health care clinics. They were visited four times during pregnancy and three times during puerperium and were provided an education program and counseling. Data were collected from the records made during monitoring the women and focus group discussions with women, peer trainers and health care staff. They were found to acquire appropriate health behaviors, 36.2 % women started to receive health care from primary health care clinics for the first time and 86.9 % of the deliveries were performed at health centers. The pregnant and puerperal women were satisfied with home visits, felt special and put the information about self-care into practice. The number of the women receiving iron supplements and vaccine against tetanus and receiving regular care increased.

Comparison of responses to Ovsynch between Holstein-Friesian and Swedish Red cows

The Ovsynch protocol was designed to synchronize ovulation, thereby allowing timed artificial insemination (TAI) of all cows without detection of estrus. However, the effectiveness of Ovsynch in different breeds of dairy cows has not been previously compared. The aim of this study was to compare the response to Ovsynch in cycling lactating Holstein-Friesian (HF) and Swedish Red (SR) dairy cows. A total of 495 cyclic cows (n=347 HF, n=148 SR) were housed together and treated with Ovsynch (GnRH-7 d-PGF2α-56 h-GnRH-16 to 18 h-TAI). Ovulatory responses, synchronization rate, maximal follicle size at the time of AI, and percentage of pregnant cows per AI (P/AI at 31 and 62 d after AI) were compared between breeds. Ultrasonography was performed during Ovsynch at first GnRH, PGF2α, at time of AI, and 7 d after AI. Ovulatory response and synchronization rate were similar in HF versus SR cows (60.2 vs. 62.2%; 88.4 vs. 88.5%, respectively). Cows that ovulated to the first GnRH of Ovsynch had smaller follicle size at AI (15.9±0.1 vs. 16.4±0.2 mm). Maximal follicle size at AI was greater for HF (16.4±2.2 mm) than SR (15.5±2.3 mm) cows. The P/AI was greater for SR than HF cows at the 62-d pregnancy diagnosis (56.1 vs. 46.1%). In addition, pregnancy loss between 31 and 62 d of pregnancy was greater in HF (10.1%) than SR (3.5%) cows. Fertility was less in HF cows during the hot season (57.7 in cold vs. 38.1% in the hot season), whereas such a decrease was not observed in SR (60.0 in cold vs. 53.5% in the hot season) cows. Thus, although the GnRH treatments of Ovsynch were equally effective in SR and HF cows, pregnancy outcomes (P/AI at d 62 and pregnancy survival) were greater in SR than HF cows, and P/AI in SR cows was not compromised during the hot season as was found for HF cows.

A safe motherhood education and counselling programme in Istanbul

OBJECTIVE

Evaluation of an education/counselling programme intended for pregnant/puerperal women in a secondary health care facility.

METHODS

The education/counselling programme was launched in September 2004, following the preparation of environmental and material components. Evaluation of the two-year project was achieved by means of satisfaction surveys of service receivers and service providers, an information survey of service receivers and focus group discussions (FGDs) for both groups.

RESULTS

Forty percent of the pregnant women who attended antenatal visits and 90% of those who had recently delivered were given education/counselling in accordance with the project. The information survey showed that 92.5% of the pregnant women knew that they should take an iron supplement during pregnancy and the puerperium; 72% of the puerperal women knew of the danger signs postpartum and concerning the newborn, and 70% were aware of the methods of effective breastfeeding. The FGDs showed improved competence of the applicants in pre-delivery, pregnancy and puerperal care as well as in newborn nutrition. Feedback from service providers confirmed the patients' improved active participation in their self-care.

CONCLUSION

The safe motherhood education/counselling programme was successfully completed. The applicants and health care professionals benefited from the service.

Adsorption of natural organic matter from waters by iron coated pumice

Natural pumice particles were used as granular support media and coated with iron oxides to investigate their adsorptive natural organic matter (NOM) removal from waters. The impacts of natural pumice source, particle size fraction, pumice dose, pumice surface chemistry and specific surface area, and NOM source on the ultimate extent and rate of NOM removal were studied. All adsorption isotherm experiments were conducted employing the variable-dose completely mixed batch reactor bottle-point method. Iron oxide coating overwhelmed the surface electrical properties of the underlying pumice particles. Surface areas as high as 20.6m(2)g(-1) were achieved after iron coating of pumice samples, which are above than those of iron coated sand samples reported in the literature. For all particle size fractions, iron coating of natural pumices significantly increased their NOM uptakes both on an adsorbent mass- and surface area-basis. The smallest size fractions (<63 microm) of coated pumices generally exhibited the highest NOM uptakes. A strong linear correlation between the iron contents of coated pumices and their Freundlich affinity parameters (K(F)) indicated that the enhanced NOM uptake is due to iron oxides bound on pumice surfaces. Iron oxide coated pumice surfaces preferentially removed high UV-absorbing fractions of NOM, with UV absorbance reductions up to 90%. Control experiments indicated that iron oxide species bound on pumice surfaces are stable, and potential iron release to the solution is not a concern at pH values of typical natural waters. Based on high NOM adsorption capacities, iron oxide coated pumice may be a promising novel adsorbent in removing NOM from waters. Furthermore, due to preferential removal of high UV-absorbing NOM fractions, iron oxide coated pumice may also be effective in controlling the formation of disinfection by-products in drinking water treatment.
