まとめ
パスツレラ・ムルトシダ菌感染症は乳幼児ではまれですが重篤であり、多くはペットからの間接的な感染が原因です。新生児では、迅速な抗菌薬治療が良好な転帰のために不可欠です。
科学分野:
- 小児感染症; 細菌学; 人獣共通感染症
背景:
- パスツレラ・ムルトシダ菌は小児感染症ではまれな病原体であり、重篤な全身性疾患、罹患、死亡のリスクをもたらします。 この細菌は、直接的または間接的な接触による感染を伴い、家庭動物の鼻咽腔常在菌叢の一部です。
研究 の 目的:
- 家庭動物からの間接的なパスツレラ・ムルトシダ菌感染症の新生児症例を報告すること。 乳幼児感染症における人獣共通感染症の媒介の重要性を強調し、予防的衛生対策について助言すること。
主な方法:
- 全身感染を示唆する症状を呈した30日齢の男児の症例報告。 臨床検査、血液培養を含む検査、およびその後の抗菌薬療法。 2歳まで患児の臨床経過観察。
主要な成果:
- 患児は、元気消失、活力低下、高血糖などの非特異的症状で来院し、その後発熱と皮膚の変化を呈しました。 血液培養によりパスツレラ・ムルトシダ菌感染症が確認され、アンピシリンによる経験的抗菌薬療法に良好に反応しました。 患児は良好な臨床経過をたどり、長期的な発達異常は認められませんでした。
結論:
- ペットから乳幼児へのパスツレラ・ムルトシダ菌の間接的な感染(呼吸器飛沫または舐めることによる)は、重大なリスクです。 医療提供者は、ペットと乳幼児の密接な接触のリスクについて保護者に教育し、衛生を促進する必要があります。 パスツレラ・ムルトシダ菌感染症の新生児管理においては、早期認識と適切な抗菌薬治療が不可欠です。

Infants are one of the purest sources of information about human thinking and learning, because they’ve had very few life experiences. Thus, researchers are interested in gathering data from infants, but as participants in experimental research, they are a challenging group to study. Unlike older children and adults, young infants are unable to reliably speak, understand speech, or...

We combined frequency-domain near-infrared spectroscopy measures of cerebral hemoglobin oxygenation with diffuse correlation spectroscopy measures of cerebral blood flow index to estimate an index of oxygen metabolism. We tested the utility of this measure as a bedside screening tool to evaluate the health and development of the newborn...

Here, we describe a hand-rearing method for raising infant marmosets in an animal incubator. This method greatly increases the survival rate of marmoset infants, which provides the opportunity to study the development of marmoset infants with similar genetic backgrounds raised in different postnatal...

High-density electroencephalography (dEEG) is being used increasingly to study brain development and plasticity in the early years of life. Here we present an application of sophisticated analysis techniques that builds on traditional EEG recording to understand the oscillatory dynamics of rapid auditory processing in the infant brain.
