To trim or not to trim beaks? It is always a good time to raise this difficult question. Indeed, since the release of the Brambell Committee report1 on welfare in the UK in 1965, discussion on the welfare of beak-trimmed birds has continued unabated. The aim of this new book (with its 15 contributors) is not, of course, to close the debate but merely to consolidate the huge amount of scientific information available on methods welfare and alternatives to beak-trimming. In the Preface, it is stated that the book will be of interest to welfare groups, policy makers, scientists, industry leaders and students of poultry science who wish to acquaint themselves with the welfare issues associated with beak-trimming and the potential solutions for reducing the need to beak-trim poultry. This goal is achieved to the extent that most of the information (although sometimes rather concisely) is presented in the eight chapters of this 174 page book. The first chapter describes the methods and reasons for beak-trimming. Chapter 2 raises the ethical question of beak-trimming and gives some of the pros and cons of the arguments. Pain and nerve injuries induced by beak-trimming are presented in Chapters 3–5 and the production responses (improved liveability, plumage quality and feed efficiency during egg laying) of beak-trimmed birds are assessed in Chapter 6 with bird health and handling issues associated with beak-trimming in Chapter 7. The last chapter is devoted to alternatives to beak-trimming. It includes environmental enrichment methods; a consideration of the genetics of feather pecking and cannibalism; dietary recommendations to reduce cannibalism in chickens and laying hens; manipulation of light intensities and colour to modify behaviour; management of body weight; application of abrasive strips in the feed trough to blunt the tips of the beaks of laying hens and the use of fitted devices and stock wound spray in injured birds to prevent further pecking. Among all these alternatives, the genetic solution might well prove to be the most sustainable, efficacious and cost effective. Overall, however, throughout the book this reviewer had the feeling, rightly or wrongly, that it was mostly written by opponents of beak-trimming and that arguments of the defence were sometimes omitted.

Since mid-december 2003, an epizootic of highly pathogenic avian influenza (type A, sub-type H5N1) occurs in eastern and south-eastern Asia. This epizootic is historically unprecedented in its virulence, geographical spread, and economic consequences for the agricultural sector. Implications for human health were registered in Vietnam and in Thailand. This paper summarizes the current knowledge about the risk evaluation of the transmission of avian influenza virus to humans. The current asian epizootic has highlighted the key role of global health information systems and also the need for exhaustive notification of human and animal cases. It reinforces the concept of veterinary public health. [less ▲]

A collection of 1601 extraintestinal and intestinal Escherichia coli isolated from chickens, turkeys and ducks. in Belgium, France and Spain, was hybridised with gene probes specific for fimbrial and afimbrial adhesins (F17, F18, S (Sfa/F1C), Bfp, Afa, Cs31A, Intimin (Eae), Aida-1) of intestinal, urinary and invasive E. coli of mammals and with a probe specific for the P (Pap/Prs) fimbrial adhesin of urinary and invasive E. coli of mammals and birds. Three hundred and eighty-three strains (23.9%) were P-positive, 76 strains (4.8%) were Afa-positive, 75 strains (4.7%) were F17-positive, 67 strains (4.2%) were S-positive, 23 (1.4%) were Intimin-positive. and all were F18-, Cs31A-, Aidal- and Bfp-negative. The 75 F17-positive strains harboured different major subunit A-encoding gene variants, but the f17Ac variant was the most frequent (52 strains, 69,3%) and seven strains (9.3%) were not typeable. The f17G gene variant coding for the GII adhesin was the most frequent (56 strains, 75.0%), whereas the f17GI gene variant was present in four strains (5%) and 15 strains (20.0%) were not typeable. All Afa-positive strains harboured the afa-8 variant. The 23 Intimin-positive E. coli tested positive for the beta -variant (16 strains; 69.6%) or for the gamma -variant (seven strains;, 30.4%) of the eae gene. Chicken and turkey E. coli were more frequently probe-positive (43.6 and 43.1 %, respectively) than duck E. coli 31.5%) and extraintestinal E. coli were also more frequently probe-positive (48.4%) than intestinal strains (18.5%). Different combinations of probe positive hybridisation results were observed in 72 of the 540 probe-positive E. coli (13.3%). The most frequent combinations were between AfaE-8 and F17 probes (47 strains; 8.7%) and between P and S probes (13 strains. 2.4%). Although f17- and afa-8-related DNA sequences can be plasmid-located in mammalian E. coli. they were not in avian E. coli. Besides the P fimbrial adhesin, F17 and S fimbrial and Afa-VIII and Intimin afimbrial adhesins may thus represent colonisation factors of avian pathogenic E. coli. (C) 2002 Elsevier Science B.V.

Myxomatosis is a major viral disease of the European rabbit (Oryctolagus cuniculus). Two forms of the disease (nodular and amyxomatous) exist. The clinical diagnosis of the nodular form is easily performed on the basis of typical skin lesions whereas that of amyxomatous forms must be based on virus isolation or detection of specific antibodies to myxoma virus (MV). The seroprevalence of MV was studied between March 1998 and February 1999 in 16 farms from three European countries considered free of myxomatosis on the basis of the absence of typical clinical signs. MV antibodies were detected by enzyme-linked immunosorbent assay (ELISA) (sensitivity 100%, specificity 90%) in all 16 farms; the seroprevalences corrected for test inaccuracy (95% confidence interval) were 55+/-7.7% and 37+/-6.1% for does and broilers, respectively. The association between herd sizes, types of rabbitries, and presence of recurrent respiratory or digestive troubles and seroprevalence of MV antibodies was tested in logistic multiple regressions. In all models, the seroprevalence of MV antibodies was significantly higher in herds (does and broilers) with recurrent respiratory or digestive troubles than in herds without these problems. The seroprevalence was also higher in herds (does and broilers) where animals were housed totally or partially in outdoors rabbitries than in totally enclosed rabbitries. The effect of herd sizes on the presence of MV antibodies was the same in does and broilers; intermediate sizes were at lower risk than the smaller and larger ones. [less ▲]

The virulence of five amyxomatous myxoma virus (MV) strains, the clinical and pathogenetic effects of which had been studied previously in specific pathogen-free (SPF) rabbits, was determined by inoculation of five groups of 10 crossbred New Zealand White/Californian conventional rabbits. A much more acute myxomatosis syndrome was produced in conventional rabbits than that reproduced previously in SPF animals. However, the main clinical signs were of the respiratory type. The MV strains MYX 254/95 and 801 appeared very virulent, killing all the inoculated animals. The strains MYX 217/95, MYX 555/94 and Saint Benoist were somewhat attenuated, killing only seven, six and six rabbits, respectively. Extensive lung lesions due to supervening bacterial infections were observed in 36 of the 39 rabbits that died. Lethality was found to be a better estimate of virulence than mean survival time. By 98 days after viral inoculation, all the surviving animals had completely recovered. At that time, they were immunosuppressed by treatment with adrenocorticotrophic hormone (ACTH) for 10 days to determine whether they still harboured the virus. After the ACTH treatment, eight of the 11 surviving rabbits showed clinical signs that resembled amyxomatous myxomatosis. All the virological examinations performed on naso-conjunctival exudate, on mononuclear cells, on eyelids and on ovaries remained negative but infectious virus was isolated from the testes of three of six surviving male rabbits.

Sixty-six rabbits, with no history of vaccination against myxomatosis and which had died of pulmonary lesions, were submitted for virological and serological tests for Myxoma virus (MV) infection and for bacteriological examinations. At post mortem, the diagnoses based on observed lesions were as follows: acute haemorrhagic pneumonia (38%); acute suppurative bronchopneumonia (35%); and fibrinohaemorrhagic bronchopneumonia with fibrinous pleuritis (27%). MV was isolated from 10% of the rabbits, mainly from those with acute haemorrhagic pneumonia. Serological evidence of MV infection was demonstrated in 44% of rabbits. Pathogenic bacteria species isolated from lungs were Pasteurella (spp. and multocida), Escherichia coli, Bordetella bronchiseptica and Pseudomonas aeruginosa, respectively, from 41, 11, 7 and 6% of samples. No relationship could be established between the presence of specific antibodies to MV and the observed pulmonary lesions or the results of the bacteriological examinations. A significant trend was established between the severity of the lesions and the results of the bacteriological examinations. [less ▲]

The present paper describes chondrodystrophy (perosis) in three poultry units producing labelled chickens. An unilateral deviation of a hind leg along with a tumefaction of the tarsal joint appeared in 4-day- to 4-week-old birds; 5 to 50% of the animals were affected. The growth rate was reduced and cachexia was also observed. There were also breast blisters. Chemical analyses were carried out on the poultry feed in two of the units. The manganese content was below the requirements at about 35 mg/kg; in one unit, the ionic balance (Na+K-Cl) was insufficient along with a too narrow Ca/P. The insufficient supply in manganese was corrected by the addition of manganese sulfate in water at a rate of 120 g/litre of water. Manganese sulfate was also added in the feedstuff at a rate of 120 g/ton. [less ▲]

Two types of myxomatosis vaccine are available commercially, namely, vaccine prepared from the Shope fibroma virus (SFV) and that prepared from an attenuated myxoma virus (MV) strain, e.gSG33. An experiment was designed to compare two vaccination schemes for their ability to protect rabbits against challenge with either a virulent amyxomatous MV strain or a virulent nodular MV strain. Apart from a difference in the cutaneous expression of the disease, the two challenge strains resembled each other in respect of mortality rate, naso-conjunctival shedding of virus, and tissue infection. Vaccination with SFV alone failed to prevent clinical signs, naso-conjunctival shedding or tissue infection. Vaccination with SFV followed by a booster inoculation with SG33 protected rabbits against the development of clinical signs and significantly reduced both viral shedding in naso-conjunctival exudates and viral infection of eyelids, lungs and testes; virus was, however, isolated from testes of some surviving animals.
