Protothecal Mastitis

Öz

Backround/Aim:Mastitis is the inflammatory diseases of the udder tissue in dairy cattle. This mammary gland infection is the most common disease in dairy cattle in our country. It is also the most costly to the dairy industry. P. zopfii Prototheca zopfii have been described as a global problem with reported in several countries. P. zopfii strains are often associated with wet conditions and organic matters, and widely dispersed in dairy environments. Since P. zopfii was first identified as a pathogen of bovine mastitis in 1952, the incidence of mastitis due to this microalga is steadily increasing and gaining more and more economic loses. However, bovine mastitis due to this microalga has not been reported in our country. The aim of this study is to give information about aetiology, epidemiology, diagnosis and treatment of Protothecal mastitis. Conclusion:There are five species of prototheca including P. moriformis, P. stagnora, P.ulmea, P. wickerhamii, and P. zopfii in the nature in saprophyte form and can be isolated from different environmental sources such as stool, soil, lakes, and mires. Protothecosis is a zoonotic infection. P. zopfii, and P. wicherhamii are etiological agents of human Protothecosis. Several reports showed that strains of P. zopfii genotype 2 were responsible mainly for bovine mastitis. Studies on the in vitro susceptibility profile of the Prototheca genus have revealed great resistance to conventional antimicrobial and antifungal agents. These microalgae do not respond to routine mastitis therapy, and the only control measure to date has been the elimination of the infected cows.

Özbilgi/Amaç: Mastitis, süt ineklerinin meme dokusunun yangısal bir hastalığıdır. Bu meme bezi hastalığı ülkemiz sütçü ineklerinde en sık görülen hastalıktır ve süt endüstrisinde büyük maddi gidere yol açmaktadır. Prototheca zopfii P. zopfii birçok ülkede mastitis salgınlarından sorumlu küresel bir problem olarak tanımlanmaktadır. P. zopfii süt ineği çiftliklerinin çevre koşullarında, nemli ortamlarda ve organik materyallerde sıklıkla bulunmaktadır. P. zopfii’nin ilk olarak 1952 yılında patojen mastitis etkeni olarak identifiye edilmesinden bu yana etkenin mastitis vakalarında görülme sıklığı gittikçe artmakta ve yüksek ekonomik kayıplara yol açmaktadır. Ülkemizde Prototheca türlerinin oluşturduğu sığır mastitislerine yönelik bir bildirim henüz rapor edilmemiştir. Çalışmanın amacı, Prototekal mastitislerin etiyolojisi, epidemiyolojisi, tanı ve tedavisi hakkında bilgi vermektir. Sonuç: Prototheca cinsi, doğada saprofit durumda olan ve dışkı, toprak, durgun sular ve bataklıklardan izole edilebilen P. moriformis, P. stagnora, P.ulmea, P. wicherhamii, ve P. zopfii olmak üzere beş türü barındırmaktadır. Prototekozis zoonoz bir infeksiyondur. Aynı zamanda P. zopfii, ve P. wickerhamii insan Prototekozis’inde yer alan etiyolojik ajanlardır. Birçok çalışmada ise sığır mastitislerinden P. zopfii genotype II sorumlu tutulmaktadır. Prototheca’ların invitro duyarlılık profilleri incelendiğinde konvansiyonel antimikrobiyal ve antifungallere karşı oldukça dirençli oldukları görülmektedir. Bu mikroalg, rutin mastitis tedavilerine cevap vermemektedir. İnfekte sığırların sürüden elimine edilmesi, Prototekal mastitislerin kontrolü için tek yol gibi gözükmektedir.
