Giardia spp. İle Doğal İnfekte Buzağılarda Hipomagnezemi

Magnezyum enerji metabolizmasında birçok enzimin aktivasyonuna katılan makromineraldir. Diyetle alımının ve absorbsiyonunun azalması veya konjenital metabolik hastalıklar sonucu Mg eksikliği şekillenebilmektedir. Bu olgu sunumunda 2 aylık yaştan küçük, doğal olarak giardiazisli 11 ishalli buzağıda Mg düzeyleri araştırıldı. Hasta başı hızlı test kitleriyle Giardia duodenalis pozitif saptananlarda, tanının kesinleştirilmesi amacıyla dışkı örnekleri çinko sülfat flotasyon/Giemsa boyama ile incelendi. Mg seviyeleri Vet Photometer 700 DP cihazı ile enzimatik-kolorimetrik yöntemle belirlendi. Hasta buzağılarda Mg seviyeleri (min-maks) 0.15-0.41 mmol/L arasında bulundu. Elde ettiğimiz bulgular literatürlerdeki sağlıklı referans grubu ve aynı yaştaki buzağılar (0,8-1,6 mmol/L) ile hipomagnezemili ancak giardiazisi bulunmayanlarda (0,4-0,5 mmol/L) saptanan referans aralıklarına göre daha düşük seviyelerde Mg tespit edildiğini göstermektedir. Sonuç olarak Giardia spp. ile doğal infekte buzağılarda, malabsorpsiyon ve diyarenin magnezyum emilimini bozarak hipomagnezemiye sebep olabileceği söylenebilir.

Hypomagnesemia In Naturally Infected Calves With Giardia spp.

Magnesium is macro mineral contributed to activation of many enzymes in energy metabolism. Magnesium deficiency is formed as a result of inadequate diet intake, reduction of absorption or congenital metabolic disease. In the present report, Mg levels were analyzed in 11 diarrheic calves, less than 2 months of ages and naturally infected with giardiasis. Diagnosis was made on rapid test kits against G. duedenalis, and confirmed by zinc sulphate flotation or Giemsa staining. Mg levels determined by Vet Photometer 700 DP device with enzymatic-colorimetric method. Mg levels were found between the ranges of (min-max) 0.15-0.41 mmol/L in naturally infected calves. Our findings indicated lower Mg levels when compared with literaturally indicated healthy and age-matched calves (0,8-1,6 mmol/L) and hypomagnesemic calves without giardiasis (0,4-0,5 mmol/L). Consequently, it may be concluded that malabsorption and diarrhea might cause hypomagnesemia by blocking intestinal Mg absorption in naturally infected calves with Giardia spp,
