Although ethnicity by itself was not significantly associated with outcome, factors related to ethnicity might have contributed to these differences between tribals and non-tribals.”
“The present study was conducted to determine the prevalence and incidence of trypanosomosis and to investigate some factors influencing them in an agro-pastoral area of southwestern Burkina Faso. A total CA3 nmr of 363 crossbred cattle (Baoule-zebu peul), which were bred under natural trypanosomosis challenge, were monitored monthly for parasitaemia, packed cell volume (PCV) and serological analyses over 2 years. The parasitological
prevalence estimated at the beginning of the survey using the buffy coat technique (BCT) was 7.54%. As much as 66.7% of all trypanosome infections were due to Trypanosoma vivax, 23.8% due to Trypanosoma congolense and 9.5% due to T. vivax/T. congolense mixed infections. The monthly serological Gamma-secretase inhibitor incidence varied from 0.29% to 19.29%.
The season was the most important factor influencing
the serological prevalence and incidence and the animal PCV. The dry hot season is associated with increasing seroprevalences and incidences and consequently a decreasing average of PCV. In addition, an important spatial heterogeneity was observed. (C) 2009 Elsevier Ltd. All rights reserved.”
“SETTING: Published literature on the clinical characteristics of tuberculosis (TB) among elderly patients in India is scarce, as the problem of geriatric TB has not received the attention it deserves.
OBJECTIVES: To compare the manifestations of TB among elderly and young patients.
DESIGN: Medical records of elderly and young TB patients were extracted and compared.
Elderly patients had less frequent respiratory and constitutional symptoms, but a higher prevalence of comorbidities. The median duration of symptoms was also longer in the elderly. Both groups were similar Selleck GDC 973 on physical examination, except that the elderly had a higher frequency of development of jaundice following anti-tuberculosis chemotherapy. Human immunodeficiency virus positivity was only present among the younger group. Both groups had significant proportions of alcoholics and drug abusers, but lesser percentage of smokers. Total admission analysis showed a male preponderance.
CONCLUSION: The presentation of TB in elderly patients differs from that of younger patients in symptomatology. A high index of suspicion is therefore required to make a timely diagnosis of TB in the elderly.”
“Nor98 is an atypical scrapie strain characterized by a molecular pattern and brain distribution of the pathological prion protein (PrP(sc)) different from classical scrapie. In Italy, 69 atypical cases have been identified so far and all were characterized as Nor98 strain. In this paper we report an unusual case in a sheep which showed immunohistochemical and molecular features of PrPsc different from the other atypical cases.
