Anticoccidial effects ofGalla rhoisextract onEimeria tenella-infected chicken

Abstract

Anticoccidial effects of Galla rhois (GR) extract were evaluated in chickens after oral infection with Eimeria tenella. This study was performed using 3-day-old chickens (n=30). The animals were divided into 3 groups as follows: GR 0.5%/infected (n=10), untreated/infected (n=10), and non-infected control (n=10). The chickens were fed a standard diet supplemented with or without GR for 1 week before infection with E. tenella (10,000 sporulated oocysts per chicken). The effects of GR on E. tenella infection were assessed by 2 parameters, number of fecal oocysts and body weight gain, and the results of the polymerase chain reaction (PCR). The GR-fed chickens produced significantly lower number of fecal oocysts (P<0.05) than the E. tenella-infected chickens who were fed the standard diet. In addition, GR-based diet improved the loss of body weight caused by E. tenella infection. Positive findings of PCR were identified by distinct bands in the samples of E. tenella-inoculated chickens. However, PCR analysis revealed no E. tenella oocysts in the feces of GR-fed chickens. Our data showed that GR extracts had remarkable anticoccidial activities against E. tenella. This finding might have implications for the development of novel anticoccidial drugs.

Anti-ulcer effect of Gallarhois extract with anti-oxidant activity in an ICR model of ethanol/hydrochloride acid-induced gastric injury

“…Gallarhois (GR) is a traditional oriental drug used to treat diarrhea, persistent coughing and spontaneous perspiration, although there is little scientific evidence supporting these pharmacological effects in humans. Recently, several studies revealed that tannin-derived components of GR effectively inhibit bacteria, fungi and viruses 30, 31. In addition, methyl gallate and ethyl gallate isolated from GR also showed significant anti-inflammatory activity in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages via induction of hemoxic enzyme 1 and inhibition of iNOS/COX-2 22, 32.…”

Anticoccidial effectivity of a traditional medicinal plant, Cinnamomum verum, in broiler chickens infected with Eimeria tenella

“…After the confirmation of the parasite species, oocysts were collected, sporulated, and washed, and the dose was adjusted to 4 × 10 4 /100 μL/bird. At 21 d of age, all the birds, except for group 5, were orally gavaged with a 1 mL suspension of distilled water containing 40,000 E. tenella sporulated oocysts ( Lee et al., 2012 ).…”

“…Oocysts were then collected, sporulated, washed, and adjusted to 1 × 10 4 /100 µL/bird. A total of 10,000 sporulated oocysts were administered orally (gavage) to each experimental chicken in 1 mL of distilled water [ 40 ].…”
