The ocular surface is perpetually exposed to the external environment, rendering it susceptible to microbial contamination. The ocular surface microbiota consists of non-pathogenic microorganisms that inhabit the conjunctiva and cornea. This study's objective was to extensively review the prevalence of bacterial and fungal organisms in the conjunctiva of healthy and diseased cats. (Herpes- and Calici-infected groups).
The current study was performed on 240 cats that had visited veterinary health centers (Tehran, Iran) for examination. Sterile swabs from each cat's eyes were investigated for microbiological assessment. After sample collection, viral pathogens (Herpes and Calici viruses) were isolated and identified using the PCR method. The ages of the investigated group were 3.76, 3.93, and 4.15 months.
The highest frequency of bacteria in the normal, Herpes-infected/Calici-infected, and Herpes/Calici-infected groups were associated with and , and respectively. In addition, it was found that the high prevalence of fungal microorganisms in the isolated samples was related to yeasts, , and species.
Bacterial prevalence was significantly higher in all groups than the prevalence of fungi in the eyes of cats. The statistical comparison between the study groups regarding microbial and fungal frequency showed that significant differences were found between them, such that the frequency was higher in all disease groups, against the control group. In addition, a significant relation was observed between the Herpes-infected and Calici-infected groups regarding microbial and fungal prevalence.
眼表长期暴露于外部环境,易受微生物污染。眼表微生物群由栖息于结膜和角膜的非致病微生物组成。本研究的目的是广泛回顾健康和患病猫(感染疱疹病毒和杯状病毒的组)结膜中细菌和真菌的流行情况。
本研究对240只到兽医健康中心(伊朗德黑兰)检查的猫进行。对每只猫眼睛的无菌拭子进行微生物学评估。样本采集后,使用聚合酶链反应(PCR)方法分离和鉴定病毒病原体(疱疹病毒和杯状病毒)。研究组的年龄分别为3.76、3.93和4.15个月。
正常组、感染疱疹病毒/感染杯状病毒组以及感染疱疹病毒和杯状病毒组中,细菌的最高频率分别与 、 和 相关。此外,还发现分离样本中真菌微生物的高流行率与酵母、 和 菌种有关。
猫眼中所有组的细菌流行率均显著高于真菌流行率。研究组之间关于微生物和真菌频率的统计比较表明,它们之间存在显著差异,所有疾病组的频率均高于对照组。此外,在感染疱疹病毒组和感染杯状病毒组之间,观察到微生物和真菌流行率存在显著关系。
