ABSTRACT
Background: Taenia solium infections in humans include the infection by the adult tapeworm, these infections are of public health concern and are among the most important afflictions of humans who live in areas of poverty in the developing world and least developed countries. T. solium, a zoonotic disease, transmitted between pigs and humans and among humans, is common in developing countries. Aims and Objectives: The aim of the study was to estimate the detection rate of T. solium taeniasis among patients and random community screening with an indication of intestinal parasitic infection by routine stool examination. Materials and Methods: Stool samples were collected from the community and patients. Those who were willing, samples were screened for the cysts/ova/egg by direct microscopic examination by saline, iodine, concentration technique, and modified acid fast staining, were performed to differentiate species of T. solium and Taenia saginata. Results: Overall samples were 2030, out of which 870 stool samples were from community field screening 585 (28.81%) were positive. 1160 from tertiary care center, 668 (32.90%) were positive gave a total prevalence of intestinal parasitic infection of 61.72%. The prevalence of T. solium taeniasis was 194 (9.55%) out of which 92 (4.53%) were from community and 102 (5.02%) were from tertiary care center. Conclusion: The high prevalence of intestinal parasitic infestation might be due to the poor sanitary, contaminated water, and lack of education that is prevalent in the studied region as in other pockets in rural India. Our study showed the usefulness of the Ziehl-Neelsen modified acid-fast stain for identification of Taenia species.
ABSTRACT
Introduction: Campylobacter-mediated diarrhoea is one of the major causes of gastroenteritis globally. A majority of the Campylobacter spp. that cause disease in humans have been isolated from animals. Faecal contamination of food and water is the identified frequent cause of human campylobacteriosis. Methodology: In the present study, faecal samples from patients with symptoms of acute diarrhoea (n = 310) and domestic animals including cows (n = 60), sheep (n = 45) and goats (n = 45) were collected from the same localities in the peri-urban Bhubaneswar city. Genomic DNA isolation followed by polymerase chain reaction and sequencing was employed to analyse Campylobacter spp.-positive samples. Results: Of the 460 faecal samples, 16.77% of human samples and 25.33% of animal samples were found to be positive for Campylobacter spp. Among animals, the isolation rate was highest in sheep followed by cows and goats with 9.33%, 8.66% and 7.33%, respectively. The highest number of Campylobacter-positive cases was diagnosed in infants of 2–5 years age. Concurrent infection of other pathogens in addition to Campylobacter spp. was frequently detected in the samples. Conclusion: The present study showed the incidence of Campylobacter infections in human and different animal species in and around Bhubaneswar, Odisha. The analysis suggested that domestic animals can be the potential sources for human campylobacteriosis in the region.
