Hematološke i biokemijske promjene u serumu nazimica pokusno invadiranih protozoonom Trypanosoma brucei

The aim of this experiment was to study the hematological and serum biochemical changes in domestic cross breed female gilts infected with Trypanosoma brucei parasites. Twelve gilts were purchased from piggeries in Zaria Nigeria and housed in clean, fl y proof pens in two groups of six infected and six controls. The gilts in the infected group were inoculated with approximately 1.8 × 106 Trypanosoma brucei parasites. All the inoculated gilts developed clinical trypanosomosis after a prepatent period of three (3) days. Significant differences (P<0.05) were observed in the mean values of Packed Cell Volume (PCV), total white blood cells and differential leukocytes count, serum proteins, aspartate amino transferase, creatine kinase, potassium, inorganic phosphates and calcium between the infected gilts and the controls. The implication of these findings in the pathology of trypanosomosis in this species is discussed.Cilj je bio istražiti hematološke i biokemijske promjene u serumu križanih nazimica invadiranih nametnikom Trypanosoma brucei. U istraživanje je bilo uključeno 12 nazimica nabavljenih na svinjogojstvima u Zariji u Nigeriji. Nazimice su bile podijeljene u pokusnu i kontrolnu skupinu te smještene u nastambe potpuno zaštićene od krilatih kukaca. U pokusnoj skupini bile su invadirane s približno 1,8 ×106 parazita Trypanosoma brucei. U svih invadiranih nazimica očitovali su se klinički znakovi tripanosomoze nakon prepatentnog perioda od tri dana. Značajne razlike (P<0,05) bile su primijećene u srednjim vrijednostima hematokrita, leukocita, diferencijalne krvne slike, serumskih proteina, aspartat aminotransferaze, kreatin kinaze, kalija, anorganskih fosfata i kalcija. U radu je raspravljeno značenje tih nalaza u patologiji tripanosomoze u svinja

Anthelmintic efficacy of extracts of Spigelia anthelmia Linn on experimental Nippostrongylus braziliensis in rats

Spigelia anthelmia Linn is used as a herb and is a common annual weed of cultivation in open re-growths, on unused land in towns as well as on road sides. The plant can grow to approximately 30 cm in height. The aim of this study was to screen extracts of Spigelia anthelmia for their anthelmintic activity against an experimental Nippostrongylus braziliensis infection in rats. Acute oral toxicity occurred at a dose of 1,140mg/kg, while anthelmintic trials against Nippostrongylus braziliensis in rats using the aqueous fraction showed a progressive decrease in worm count with increasing dose (10, 13, 16, 20 and 25 mg per kg body weight) (p < 0.05). At 25 mg per kg body weight, the worm count was significantly lower than that at 10mg per kg body weight (p < 0.05)
