Background and Aim: Campylobacter species have been recognized as the most frequently identified bacterial cause of human gastroenteritis. The aims of this study were to identify Campylobacter jejuni and Campylobacter coli species isolated from chicken meat and to analyze the differences in the melting curve patterns of both species.
Materials and Methods: A total of 105 chicken meat samples collected from slaughterhouses and retailers in six provinces in Indonesia were examined for the isolation and identification of Campylobacter spp. A total of 56 positive isolates of Campylobacter spp. were analyzed using the quantitative real-time polymerase chain reaction and high resolution melting method.
Results: The prevalence of Campylobacter spp. in chicken meat was found to be 61.9%. Regarding the identification, 23 isolates (41.07%) were C. jejuni, 22 (39.29%) were C. coli, six (10.71%) were a mix between C. jejuni and C. coli, and five isolates (8.93%) were Campylobacter spp. All the C. jejuni and C. coli isolates produced varied melting curve patterns.
Conclusion: The high prevalence of C. jejuni and C. coli in chicken meat in Indonesia indicates a high risk of the incidence of campylobacteriosis in humans.
The objective of this study is to observe the relationship of development of adrenocorticotropic hormone (ACTH) cells of adenohypophysis–adrenal cortex axis during pre and postnatal period of longtailed monkey (Macaca fascicularis). Five fetuses aged 70, 85, 100, 120, and 150 days of gestation and 2new born aged 10 and 105 days old were used as research materials. The sections of the pituitary gland stained immunohistochemically using human ACTH antiserum and the adrenal glands stained by Hematoxylin-Eosin procedures. At the fetus 120 days old, the ACTH cells and blood vessel of fetaladenohypophysis developed well and its similar that found in older age. This condition suggested distributing the ACTH to whole body optimally. At the same time, the adrenal cortex cells of fetus 120 days old were active in proliferation and differentiation processes to form transition zone that lies between definitive and fetal zones, and central vein also developed in adrenal gland. In fetus aged 150 days, the cortex adrenal structure was similar with found in older fetus. The adenohypophysis ACTH cells developed earlier than adrenal cortex and their secretion suggested influencing the development of adrenal cortex cells of long-tailed monkey.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
