Eperythrozoonosis

Dünyanın her yerinde hayvanlarda yaygın olan Eperythrozoon türleri, Türkiye’de sadece sığır ve farelerde tespit edilmiştir. Eperythrozoon türleri kanda ikiye bölünerek çoğalırlar. Çok sayıda yuvarlak, yüzük, çomak, dikdörtgen veya çok şekilli formlarda yığınlar halinde eritrositlerin yüzeyinde ve plasmada serbest olarak bulunurlar. Hastalık zayıf bir parasitemi, hafif anemi, hafif ateş ve icterus ile seyreder. Splenektomi çok yüksek bir parasitemi üretir. Anemi gelişmiş, dalağı büyümüş ve splenektomi yapılmış hayvanlarda hastalık göz önüne alınmalıdır. Etkenlerin tabii naklinden Arthropoda sorumludur. En önemli vektörlerin kan emen bitler olduğu bilinmektedir. Etkenler oral ve parenteral yollarla nakledilebilir. Tetracycline, oxytetracycline, chlortetracycline, neosalvarsan, aureomycine ve arsenik tedavide oldukça etkilidir.

Eperythrozoonosis

While Eperythrozoon species are common all over the world, In Turkey, they are detected only in cattle and mice. Eperythrozoon species propogate in blood by dividing into two. They are found on erythrocyte surfaces or in plasma in high numbers in different shapes including, circular, rod, ring, rectangular or multiform shapes. Commonly seen latent infections are characterized with a weak parasitemia, light anemia, weak fever, and icterus. Splenectomy results in high level of parasitemia. Disease should be considered in animals with anemia, enlarged spleen and animals with splenectomy. Arthropoda are responsible for natural transmission of parasites. It is well known that bloodsucking fleas are the most important vectors. Parasites can be transported by oral or parenteral routes. Tetracycline, oxytetracycline, chlortetracycline, neosalvarsan, aureomycine and arsenic are very effective in the treatment.
