Campylobacteriosis, is a zoonotic bacterial disease observed with a rising worldwide. It is becoming the most commonly recognized cause of bacterial gastroenteritis in under-five mortality in recent years. This study was done to determine the prevalence and determinants of Campylobacter infection among under-fives with acute watery diarrhea.
This institutional-based cross-sectional study was conducted at governmental and private health institutions in Hawassa city. All outpatient under-five children who met the inclusion criteria from April 2021 to August 2021 were enrolled in this study. Demographic and clinical data were obtained using a standardized data collection tool. Stool samples were collected from each participant with a sterile container and inoculated on a campylobacter agar media. The isolates were identified by using biochemical tests and a disc diffusion technique was performed to determine the antimicrobial sensitivity patterns of the isolates. Data were entered and analyzed using SPSS version 21. Descriptive and Logistic regression analysis was applied to determine the determinants of Campylobacter infection. P-value < 0.05 was considered statistically significant.
A total of 235 under-five children were enrolled in this study with a 100% response rate. Of these 130 (55.3%) and 105(44.7%) were males and females respectively with the age range of 2 months to 60 months with the mean age of 25 months. The majority of the 150 (63.2%) were rural residents. Of 235 under-fives with acute watery diarrhea, 16 (6.8%) patients were found to have Campylobacter infection with (95% CI, 3.8-10.2%). Consumption of pasteurized milk (AOR: 0.12; 95% CI 0.02-0.75, P<0.05), presence of domestic animals like cats, hens, and cows (AOR: 0.09: 95% CI 0.01-0.67, P<0.05), absence of handwashing practice before food preparation (AOR: 3.63, 95% CI 1.15-11.46, P<0.05) showed significant association with campylobacter infection. The antimicrobial susceptibility patterns of the isolated bacteria were 100% sensitivity to Azithromycin, Chloramphenicol, and Gentamicin, however; it was 100% resistant to Cephalothin. The associations of socio-demographic, environmental, and behavioral factors were compared and consumption of unpasteurized milk, the presence of domestic animal like the cat was significantly associated.
Campylobacter infection showed a comparatively low prevalence in under-fives with acute watery diarrhea. In this study contact with cats, consumption of unpasteurized milk were associated with Campylobacter infection. The treatment approach of Campylobacter infection must consider the sensitivity profile of antibiotics as indicated in the study. We, therefore, recommend further studies to determine the species responsible for Campylobacter infection with other co-morbidities and the susceptibility pattern for each species to indicate appropriate antibiotic therapy.
弯曲菌病是一种在全球范围内呈上升趋势的人畜共患细菌性疾病。近年来,它已成为导致五岁以下儿童死亡的细菌性肠胃炎的最常见原因。本研究旨在确定急性水样腹泻的五岁以下儿童中弯曲菌感染的流行率及其决定因素。
本研究为在 Hawassa 市的政府和私人医疗机构进行的基于机构的横断面研究。所有符合纳入标准的 2021 年 4 月至 2021 年 8 月的门诊五岁以下儿童均纳入本研究。使用标准化数据收集工具获取人口统计学和临床数据。从每个参与者处采集粪便样本,并使用无菌容器接种于弯曲菌琼脂培养基上。通过生化试验鉴定分离株,并采用纸片扩散技术测定分离株的抗菌药物敏感性模式。使用 SPSS 版本 21 输入和分析数据。应用描述性和逻辑回归分析来确定弯曲菌感染的决定因素。P 值<0.05 被认为具有统计学意义。
本研究共纳入了 235 名五岁以下儿童,应答率为 100%。其中 130 名(55.3%)和 105 名(44.7%)分别为男性和女性,年龄在 2 个月至 60 个月之间,平均年龄为 25 个月。其中 150 名(63.2%)是农村居民。在 235 名患有急性水样腹泻的五岁以下儿童中,发现 16 名(6.8%)患者存在弯曲菌感染(95%CI,3.8-10.2%)。食用巴氏消毒奶(AOR:0.12;95%CI 0.02-0.75,P<0.05)、有猫、母鸡和奶牛等家养动物(AOR:0.09:95%CI 0.01-0.67,P<0.05)、无食物制备前洗手(AOR:3.63,95%CI 1.15-11.46,P<0.05)与弯曲菌感染有显著相关性。分离细菌的抗菌药物敏感性模式为对阿奇霉素、氯霉素和庆大霉素 100%敏感,而对头孢噻吩 100%耐药。对社会人口统计学、环境和行为因素进行了比较,发现食用未经巴氏消毒的牛奶和有猫等家养动物与弯曲菌感染显著相关。
弯曲菌感染在患有急性水样腹泻的五岁以下儿童中发病率相对较低。在本研究中,接触猫和食用未经巴氏消毒的牛奶与弯曲菌感染有关。弯曲菌感染的治疗方法必须考虑到抗生素的敏感性谱,正如研究所示。因此,我们建议进行进一步的研究,以确定引起弯曲菌感染的物种及其对每种物种的敏感性模式,以指示适当的抗生素治疗。
