Abstract

Recognized as a significant nosocomial pathogen in human medicine, Stenotrophomonas maltophilia poses a considerable threat due to its multidrugresistant profile. Despite its prominence in human infections, S. maltophilia remains an overlooked, misdiagnosed, or neglected pathogen in veterinary medicine, with limited studies and impact on various animal species. Few studies have focused on horses, dogs, goats, buffaloes, cats, sheep, cows, pigs, birds, fish, and reptiles. Besides, it has been reported in farm animals, food products, and farm environments (milking machines, bedding, feeders, etc.). The organism has an extensive range of habitats, causes infections in humans and animals, and naturally harbours multidrug resistance. It is noted that S. maltophilia can cause various clinical problems in immunocompromised animals, including soft tissue and skin infections, respiratory tract infections, severe septicemia, and cardiovascular infections. It has been isolated from cases of lymphadenitis in goats, arthritis and urinary tract infections in dogs, the respiratory system in horses, dogs and cats, pyogranulomatous hepatitis in buffalos, and mastitis in cattle. A thorough examination of the interconnectedness between human, animal, and environmental factors is paramount for the well-being of both human and animal populations. This review aims to provide an overview of the occurrence, clinical significance, and antimicrobial resistance patterns of S. maltophilia in animals, highlighting the need for increased awareness and research in this area.

Özet

Stenotrophomonas maltophilia, Xanthomonadaceae ailesinin bir üyesi olan ve genellikle toprak, su, bitki, insan ve hayvanlardan izole edilen, fermente olmayan Gram-negatif bir basildir. İnsan tıbbında önemli bir nozokomiyal patojen olduğu bilinmektedir. Stenotrophomonas maltophilia yeni ortaya çıkan bir patojendir. Dünya Sağlık Örgütü de bu organizmayı önemli bir Gram negatif, çoklu ilaca dirençli nozokomiyal patojen olarak kabul etmiştir. Düşük virulans ile kommensaldir ancak yüksek morbidite ve mortalite oranları ile ilişkili fırsatçı bir patojendir. Hayvanlarda ise göz ardı edilmiş, yanlış teşhis edilmiş veya ihmal edilmiş bir patojen olmaya devam etmektedir. Atlar, köpekler, keçiler, mandalar, kediler, koyunlar, inekler, domuzlar, kuşlar, balıklar ve sürüngenlerde az sayıda çalışmada rapor edilmiştir. Çiftlik hayvanlarında, gıda ürünlerinde, çiftlik ortamında (süt sağım makineleri, yataklık, yemlik vb. sürüntüler) izole edildiği bildirilmiştir. S. maltophilia bağışıklık sistemi baskılanmış hayvanlarda yumuşak doku ve deri enfeksiyonları, solunum yolu enfeksiyonları, şiddetli septisemi ve kardiyovasküler enfeksiyonlar dahil olmak üzere çeşitli klinik sorunlara neden olabileceğine dikkat çekilmektedir. Keçilerde lenfadenit, köpeklerde artrit ve idrar yolu enfeksiyonları, at, köpek ve kedilerde solunum sistemi, mandalarda piyogranülomatöz hepatit ve sığırlarda mastitis vakalarından izole edilmiştir.Bakterinin yaşam alanın çok geniş bir yelpazeye sahip olması, insan ve hayvanlarda infeksiyonlara neden olması, çoklu ilaç direncini doğal olarak barındırması; insan-hayvan-çevre ilişkisinin araştırılması insan ve hayvan sağlığı için hayati bir öneme sahiptir.Bu derlemede dünyada ve ülkemizde hayvanlarda yapılan çalışmalarda Stenotrophomonas maltophilia’nın varlığı hakkında bilgi verilecektir.
