Background & Aim: Q fever is an important zoonotic disease caused by infection with Coxiella burnetii, a Gram negative, obligate intracellular bacterium classified within the order Legionellales. Farmers, veterinarians, abattoir workers and laboratory personnel are among persons at risk of Q fever. The aim of this study was to determine frequency of IgM anti-Coxiella burnetii antibodies in slau...
Introduction A Q fever vaccine for humans is not currently licensed in the UK. Globally there are two broad types of vaccine currently in use or undergoing research: formalin-inactivated whole-cell vaccines such as the commercially available Q-vax in Australia, and acellular vaccines, such as trichloroacetic acid extracted (TCA) and chloroform-methanol residue (CMR) vaccines, developed in forme...
The present study investigated the effects of dietary arginine (Arg) supplementation on intestinal structure and functionality in broiler chickens subjected to coccidial challenge. The present study was a randomised complete block design employing a 3 × 2 factorial arrangement (n 8) with three dietary concentrations of Arg (11·1, 13·3 and 20·2 g/kg) with or without coccidial vaccine challenge (...
Quillaja brasiliensis (Quillajaceae) is a saponin producing species native from southern Brazil and Uruguay. Its saponins are remarkably similar to those of Q. saponaria, which provides most of the saponins used as immunoadjuvants in vaccines. The immunostimulating capacities of aqueous extract (AE) and purified saponin fraction (QB-90) obtained from leaves of Q. brasiliensis were favorably com...
کوکسیدیوز مهمترین بیماری انگلی در طیور می باشد. از آنجایی که استفاده از داروهای ضد کوکسیدیایی یا واکسیناسیون به عنوان متداول ترین روش های پیشگیری از این بیماری مورد توجه می باشند، به منظور مقایسه تأثیر این روش ها در پیشگیری از بیماری، آزمایشی تجربی انجام شد. در این بررسی تعداد 960 قطعه جوجه گوشتی نر یک روزه از سویه تجاری ross بطور تصادفی به هشت گروه آزمایشی مساوی تقسیم شده و در طول دوره آزمایش ...
Data collected monthly over a period of two years were live weight, packed cell volume (PCV), nematode faecal egg counts (FECs) and coccidial oocyst counts from faecal analyses for 100 mixed age (3-7 years) indigenous Tswana does. The aims of this experiment were to determine seasonal FECs and coccidial oocysts in these goats and quantify the relationships of these burdens to liveweight and PCV...
BACKGROUND Pandemic influenza vaccine manufacturing capacity and distribution agility is enhanced through the availability of equivalent antigen-sparing vaccines. We evaluated equivalence in terms of immunogenicity between GlaxoSmithKline Vaccines' A/California/7/2009 (H1N1)v-like-AS03 vaccines manufactured in Dresden (D-Pan), and Quebec (Q-Pan). METHODS In two studies, 334 adults 18-60 years...
Avian coccidiosis, an intestinal disease caused by protozoan parasites of the genus Eimeria, occurs worldwide. It is considered to be one of the most economically important diseases of domestic poultry. For many years, prophylactic use of anticoccidial feed additives has been the primary means of controlling coccidiosis in the broiler industry and has played a major role in the growth of this i...
Necrotic enteritis (NE) is one of the most important enteric diseases in poultry and is a high cost to the industry worldwide. It is caused by avian-specific, Necrotic Enteritis Beta toxin (NetB)-producing, strains of Clostridium perfringens that also possess in common other virulence-associated genes. In Europe the disease incidence has increased since the ban on in-feed "growth promoting" ant...
