In 2005, we dissected 102 wildfowl from the Czech Republic and 73 wildfowl from Poland including representatives of Anseriformes, Gruiformes and Gaviiformes. Schistosome infection was found in a total of 21 (29%) and 23 (23%) birds from Poland and the Czech Republic, respectively. All infected birds belonged to the order Anseriformes. The prevalences of nasal and visceral species were, respecti...

Because skin is an important physical barrier against pathogens, the ability to quickly and effectively heal wounds directly impacts an animal's health. The hormone corticosterone (CORT) has many complex effects on immune function and can slow wound healing. It has been suggested that CORT's role during wound healing may be to act as a "brake" on inflammation and cell proliferation. This projec...

In adult chickens, the housing system influences hippocampal morphology and neurochemistry. However, no work has been done investigating the effects of the early life environment on chicken brain development. In the present study, we reared 67 commercial laying hens (Gallus gallus domesticus) in two environments that differed in the degree of complexity (aviary or cage system). These two groups...

spondylitis is a reemerging epidemic spinal infection in male broiler chickens (5 to 7 weeks of age) as well as broiler breeder roosters (15 to 18 weeks of age). among various causative agents, enterococcus species and in particular e. cecorum, a gram-positive bacterium as a gastrointestinal flora of birds, have mostly been isolated. on late september 2015, a number of 10 weeks old roosters wit...

purpose : to compare the outcome of surgery and postoperative complications between using manually dissected cornea in descemet’s stripping with endothelial keratoplasty (dsek) and using eye bank automated precut cornea in descemet’s stripping with automated endothelial keratoplasty (dsaek) methods : forty eyes with indication of endothelial keratoplasty (ek) were included in this randomized pr...

Effects of different levels of choline and garlic powder on performance, liver health and immune response in broiler chickens were evaluated in this study. A factorial experiment with 2 dietary choline levels (the recommended level in Ross 308 broiler guidelines and 25 % less than the recommendation) and 3 dietary garlic powder levels (0, 5 or 10 g/kg diet) was conducted using Ross 308 broiler ...

Bisphenol-A (BPA) is a xenoestrogen that mimics the action of natural estrogen, estradiol-17β, and can disrupt the endocrine system. Present study was designed to investigate histopathological effects of BPA on some vital organs of major carp, Catla catla. Fish were exposed to various sub-lethal concentrations (1 to 4 ppm) of BPA in a semi-static system for 15 days. After the stipulated time, l...

BACKGROUND Prenatal exposure to bisphenol A (BPA) has been shown to induce obesity in rodents. To evaluate if exposure also later in life could induce obesity or liver damage we investigated these hypothesises in an experimental rat model. METHODS From five to fifteen weeks of age, female Fischer 344 rats were exposed to BPA via drinking water (0.025, 0.25 or 2.5 mg BPA/L) containing 5% fruct...
