Surveys for ectoparasites of dogs on the American Samoa islands of Aunu'u and Tutuila were conducted in June 2012, and was followed by molecular screening of samples. One species of flea, Ctenocephalides felis,and one tick species, Rhipicephalus sanguineus, were collected and tested for Bartonella and Rickettsia species via PCR. Bartonella clarridgeiae and an unnamed spotted fever group Rickettsia were detected in the fleas; the Rickettsia species was previously reported from Ctenocephalides spp. from Egypt, Thailand, USA, and the Republic of the Marshall Islands. None of the ticks were positive for Bartonella or Rickettsia species. This is the first report of flea-borne Rickettsia and B. clarridgeiae, considered an emerging human pathogen in New Zealand, from American Samoa. Ectoparasite-borne infections are easily misdiagnosed or ignored as their symptoms are often vague and similar to other illnesses (e.g., measles, dengue). Our results indicate a potential threat to human and animal health as infected fleas were collected from household pets.

We intended to calculate approximate fetal doses in pregnant women who underwent diagnostic radiology procedures and to evaluate the safety of their pregnancies. We contacted hospitals in different cities in Turkey where requests for fetal dose calculation are usually sent. Fetal radiation exposure was calculated for 304 cases in 218 pregnant women with gestational ages ranging from 5 days to 19 weeks, 2 days. FetDose software (ver. 4.0) was used in fetal dose calculations for radiographic and computed tomography (CT) procedures. The body was divided into three zones according to distance from the fetus. The first zone consisted of the head area, the lower extremities below the knee, and the upper extremities; the second consisted of the cervicothoracic region and upper thighs; and the third consisted of the abdominopelvic area. Fetal doses from radiologic procedures between zones were compared using the Kruskal-Wallis test and a Bonferroni-corrected Mann-Whitney U-test. The average fetal doses from radiography and CT in the first zone were 0.05 ± 0.01 mGy and 0.81 ± 0.04 mGy, respectively; 0.21 ± 0.05 mGy and 1.77 ± 0.22 mGy, respectively, in the second zone; and 6.42 ± 0.82 mGy and 22.94 ± 1.28 mGy, respectively, in the third zone (p < 0.001). Our results showed that fetal radiation exposures in our group of pregnant women did not reach the level (50 mGy) that is known to increase risk for congenital anomalies. Fetal radiation exposure in the diagnostic radiology procedures in our study did not reach risk levels that might have indicated abortion.
