Abstract

Objective: In this study, the results of equine blood cultures sampled during the period from 2022 to 2024 were evaluated. Samples were submitted as routine samples by veterinary practices to a veterinary diagnostic laboratory in Germany. The study focused mainly on the differentiation of the bacterial isolates. In order to place the results in a clinical context, the study was complemented by a questionnaire sent to the practices enquiring for sepsis-associated clinical signs.

Material and methods: The study was carried out retrospectively. A total of 199 blood culture samples submitted by practices located in Germany and other European countries were included into the evaluation. A questionnaire asking for the reason of the individual blood collection and possible presence of sepsis-associated clinical signs was sent to the relevant practices and the returning responses were analyzed.

Results: 50.3% (n=100) of the blood culture samples showed a positive result, divided into 71% monomicrobial and 29% polymicrobial samples. Staphylococci were most frequently detected (30.2%), followed by bacteria of the genus Enterobacterales (18.9%). Nearly half of the horses (41.3%) was pretreated with antibiotics at the time of sample collection. Respiratory infection was the most frequently listed reason (17.4%) for initiation of a blood culture analysis.

Conclusion: The results of the present study are comparable to previous studies. The isolates were not classified into clinically relevant pathogens and contaminants, as for the majority of patients only one sampling timepoint was available, making any isolate a potential causative agent for bacteremia.

Clinical relevance: Sepsis is not a specific condition, but is based on the clinical findings and the result of the performed blood culture analysis. Considering the duration of a bacteriological culture procedure as well as the commonly critical condition of the patient, availability of data concerning the most frequently occurring pathogens is essential in rapidly initiating adequate treatment.

[对2022年至2024年间马血培养样本的回顾性评估]。

目的：对2022 ~ 2024年采集的马血培养结果进行评价。样本作为常规样本由兽医惯例提交给德国兽医诊断实验室。研究主要集中在细菌分离的分化上。为了将结果置于临床环境中，该研究还通过向实践发送调查败血症相关临床体征的问卷来补充。材料和方法：回顾性研究。在德国和其他欧洲国家的实践中提交的总共199份血液培养样本被纳入评估。向相关诊所发送问卷，询问个别采血原因及是否存在败血症相关临床症状，并对反馈的问卷进行分析。结果：50.3% （n=100）的血培养标本呈阳性，其中单微生物标本71%，多微生物标本29%。检出最多的是葡萄球菌（30.2%），其次是肠杆菌属（18.9%）。近一半的马（41.3%）在采集样本时进行了抗生素预处理。呼吸道感染是开始血培养分析的最常见原因（17.4%）。结论：本研究结果与以往的研究结果具有可比性。这些分离物没有被分类为临床相关的病原体和污染物，因为大多数患者只有一个采样时间点，这使得任何分离物都是菌血症的潜在病原体。临床相关性：脓毒症不是一种特定的疾病，而是基于临床表现和进行的血培养分析的结果。考虑到细菌培养过程的持续时间以及患者通常的危急情况，获得有关最常见病原体的数据对于迅速开始适当的治疗至关重要。

期刊介绍： Die Tierärztliche Praxis wendet sich mit ihren beiden Reihen als einzige veterinärmedizinische Fachzeitschrift explizit an den Großtier- bzw. Kleintierpraktiker und garantiert damit eine zielgruppengenaue Ansprache. Für den Spezialisten bietet sie Original- oder Übersichtsartikel zu neuen Therapie- und Operationsverfahren oder den Einsatz moderner bildgebender Verfahren. Der weniger spezialisierte Tierarzt oder Berufseinsteiger findet auf seinen Berufsalltag zugeschnittene praxisbezogene Beiträge in der Fortbildungsrubrik „Aus Studium und Praxis“. Mit dem hervorgehobenen „Fazit für die Praxis“ am Ende jedes Artikels verschafft sich auch der eilige Leser einen raschen Überblick über die wichtigsten Inhalte dieser modern konzipierten Fachzeitschrift mit den vielen hochwertigen, überwiegend farbigen Abbildungen. In jedem Heft ermöglicht ein ATF-anerkannter Fortbildungsartikel den Erwerb einer ATF-Stunde (Akademie für tierärztliche Fortbildung).
