Abstract Extract Neospora caninum is an apicomplexan protozoan parasite first reported in dogs (Bjerkås et al., 1984 Bjerkås, I, Mohn, SF and Presthus, J. 1984.

[Google Scholar]) and subsequently recognised as a cause of bovine abortion (Dubey and Lindsay, 1993 Dubey, JP and Lindsay, DS. 1993. Neosporosis. Parasitology Today, 9: 452–458. [Google Scholar]). Natural N. caninum infections have been reported in other animal species including the goat, sheep, horse and deer (Dubey and Lindsay, 1996 Dubey, JP and Lindsay, DS. 1996. A review of Neospora caninum and neosporosis. Veterinary Parasitology, 67: 1–59. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The dog was recently identified as definitive host of the parasite (McAllister et al., 1998 McAllister, MM, Dubey, JP, Lindsay, DS, Jolley, WR, Wills, RA and McGuire, AM. 1998. Dogs are definitive hosts of Neosporu caninum. International Journal for Parasitology, 28: 1473–1478. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Neospora caninum has a worldwide distribution (Barber et al., 1995 Barber, JS, Holmdahl, OJM, Owen, MR, Uggla, A and Trees, AJ. 1995.

Abstract In the June 1998 issue of the New Zealand Veterinay Journal, a clinical review was published focusing on aspects of the protein nutrition of dairy cattle (Westwood et al., 1998 Westwood, CT,, Lean, IJ, and Kellaway, RC. 1998. Indications and implications for testing milk urea in dairy cattle: A quantitative review. Part 1. Dietary protein sources and metabolism. New Zealand Veterinary Journal, 46: 87–96. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The authors wrote: “Most species of rumen bacteria can use ammonia for growth, but some, particularly bacteria which ferment cell wall carbohydrates, use or have obligate requirements for amino acids and peptides (Russel et al., 1992 Russel, JB,, O’Connor, JD,, Fox, DG,, Soest, PJ, van and Sniffen, CJ. 1992.

Abstract Extract Neospora caninum is a major cause of disease in cattle and dogs, manifesting with abortions in cattle, and hind limb paresis in mostly young dogs (1) Dubey, JP and Lindsay, DS. 1996. A review of Neospora caninum and neosporosis. Veterinary Parasitology, 67: 1–59. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Previous reports from New Zealand suggest that around 30% of bovine abortions may be due to Neospora (2) Thornton, RN, Thompson, EJ and Dubey, JP. 1991. Neospora abortion in New Zealand cattle. New Zealand Veterinary Journal, 39: 129–133. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] (3) Thornton, R. 1992. Bovine abortions — Laboratory diagnosis 1991.

Abstract Extract Sir, — It appears that Drs Marshall et al.(1) Marshall, R.B., Manktelow, B.W. and Scholium, L.M. 1982. Standardisation of serology for leptospirosis. N.Z. vet. J., 30: 126–126. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] have missed the cardinal point of our paper on an unusual serological response in calves after use of a leptospiral vaccine.

[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] That point, of course, was that after use of one leptospiral vaccine, but not another, post-vaccination microscopic agglutination titres of calves were indistinguishable from post-infection titres, whatever the actual titres may have been. 相似文献

[PubMed], [Web of Science ®] , [Google Scholar] Both infections are included among the so-called slow virus diseases which are characterised by a long incubation period, protracted clinical course and persistent infection. Maedi-visna is not present in New Zealand but CAE has been detected in a number of goat flocks. 相似文献

Abstract Extract The paper by Goodwin et al ( 2004 Goodwin, KA, Jackson, R, Brown, C, Davies, PR, Morris, RS and Perkins, NR. 2004. Pneumonic lesions in lambs in New Zealand: patterns of prevalence and effects on production. New Zealand Veterinary Journal, 52: 175–9. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) which appeared in the August 2004 issue of the New Zealand Veterinary Journal highlighted the prevalence and costs to the sheep industry of pneumonia in lambs. The costs are considerable, and the article begs the question, “what can sheep farmers do to reduce the effects of pneumonia in lambs?” 相似文献

Abstract Extract Tuberculous lesions in the skin of carnivorous species such as the mustelids have often been associated with the contamination of bite wounds inflicted during intra-species conflict (Muirhead et al., 1974 Muirhead, RH, Gallagher, J and Burn, KJ. 1974. Tuberculosis in wild badgers in Gloucestershire: Epidemiology. Veterinary Record, 95: 552–555.

Epidemiology of Mycobacterium bovis infection in feral ferrets (Mustela furo) in New Zealand: II. Routes of infection and excretion. New Zealand Veterinary Journal, 45: 151–157. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). A strong association between tuberculous tonsillitis and recovery of Mycobacterium bovis from the oral cavity of ferrets ( Mustela furo) was reported by Lugton et al. ( 1997 Lugton, IW, Wobeser, G, Morris, RS and Caley, P. 1997. Epidemiology of Mycobacterium bovis infection in feral ferrets (Mustela furo) in New Zealand: II. Routes of infection and excretion. New Zealand Veterinary Journal, 45: 151–157. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). They believed that the recovery of M. bovis from the pharynx was enhanced by the act of swabbing which could damage the oral mucosal epithelium and dislodge infected mucosal macrophages. The authors speculated that tubercle bacilli could enter the oral cavity through disrupted tonsillar epithelium, although they found no evidence of epithelial damage. It is also well established that in many species, infected pulmonary secretions reach the oral cavity and contaminate saliva (Jennings, 1949 Jennings, AR. 1949.

Abstract Extract Madam;–The results of field trials of a live parainfluenza virus type3(PI 3)vaccine suggested that(PI 3)might not be the only virus involved in the initiation of outbreaks of pneumonia in lambs in New Zealand,( 5 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982. A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar])The outbreaks that were not associated with infection with(PI 3)could not be linked to infection with the other ovine respiratory viruses then known to be present in New Zealand (ovine adenovirus type 6 and the ovine variant of bovine adenovirus type 7)(( 1 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982. A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar]),( 4 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982.

A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar])suggesting that other unrecognised viruses might be involved. Respiratory syncytial virus (RSV) is a major cause of pneumonia in human infants and in cattle.( 8 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982. A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar])This virus has recently been isolated from a yearling ewe with mild rhinitis( 6 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982. A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar])and there is serological evidence of infection in adult sheep.( 3 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982. A sixth species of ovine adenovirus isolated from lambs in New Zealand. Arch. Virol., 74: 269–269. [Crossref] , [Google Scholar]),( 6 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982.

[Crossref] , [Google Scholar])However, there are no reports implicating this virus in outbreaks of pneumonia in lambs, although experimental infection of lambs with a bovine isolate of RSV resulted in reduced pulmonary bacterial clearance leading to secondary pneumonic pasteurellosis.( 2 Adair, B.M., McFerran, J.B. and McKillop, E.R. 1982.

Abstract Extract Recently, we reported on outbreaks of Leptospira interrogans serovar pomona infection in newly weaned lambs (1) Vermunt, JJ, West, DM, Cooke, MM, Alley, MR and Collins-Emerson, J. 1994. Observations on three outbreaks of Leptospira interrogans serovar pomona infection in lambs. New Zealand Veterinary Journal, 42: 133–6. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]. It was suggested that wet environmental conditions played an important role in the pathogenesis of the disease in that class of sheep. This communication presents observations on another case of ovine leptospirosis, one that occurred under different circumstances, i.e. different season, age and environmental conditions. 相似文献

Abstract Species of metastrongylid nematodes of the genus Filaroides have been recorded in various hosts throughout the world (1) Anderson, RC. 1978. “No.5. Keys to the genera of the superfamily Metastrongyloidea”. In CIH Keys to the Nematode Parasites of Vertebrates, Edited by: Anderson, RC, Chabaud, AG and Willmott, S. 3–4.

In New Zealand, the only known species is Filaroides (= Oslerus) osleri, which occurs in wart-like nodules near the bifurcation of the trachea of the dog (2) Jones, BR, Clark, WT, Collins, GH and Johnstone, AC. 1977.

Abstract Extract Most perennial ryegrass ( Lolium perenne) plants in pastures in New Zealand contain a naturally occurring fungal endophyte, Neotyphodium lolii. Endophyte-infected perennial ryegrass produces alkaloids that vary in concentration during the year. Some alkaloids enhance the persistence and productivity of ryegrass pastures by protecting them against insect attack. However, when other alkaloids are consumed they can reduce animal performance and lead to health problems. The alkaloid lolitrem B, for example, causes the neuromuscular disorder ryegrass staggers (Fletcher et al 1999 Fletcher, LR, Sutherland, BL and Fletcher, CG. 1999. “The impact of endophyte on the health and productivity of sheep grazing ryegrass-based pastures”. In Ryegrass endophyte: an essential New Zealand symbiosis Grassland Research and Practice Series Edited by: Woodfield, DR and Matthew, C. Vol. 7, 11–17. [Google Scholar]). Clinical symptoms of ryegrass staggers in animals range from slight muscular tremors through to staggering and complete collapse. Severely affected animals create management problems and are prone to accidental death. Outbreaks occur sporadically, particularly in summer and autumn and affect sheep, cattle, deer, horses, llamas ( Lama glama) and alpaca ( Lama pacos). Lolitrem B appears to be a stable compound, which tends to be concentrated in the leaf sheath at the base of the ryegrass plant and in the seed-heads (di Menna et al 1992 di Menna, ME, Mortimer, PH, Prestidge, RA, Hawkes, AD and Sprosen, JM. 1992. Lolitrem B concentrations, counts of Acremo ni um lolii hyphae, and the incidence of ryegrass staggers in lambs on plots of A. lolii-infected perennial ryegrass. New Zealand Journal of Agricultural Research, 35: 211–217. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]; Keogh et al 1996 Keogh, RG, Tapper, BA and Fletcher, RH. 1996. Distributions of the fungal endophyte Acremonium lolii, and of the alkaloids lolitrem B and peramine, within perennial ryegrass. New Zealand Journal of Agricultural Research, 39: 121–127. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Hay made from endophyte-infected perennial ryegrass contains large numbers of seed-heads and lolitrem B concentrations can be high, especially if it is made in late summer or autumn and, consequently, animals fed such hay are at risk of developing ryegrass staggers. 相似文献

Abstract Extract A single case of the inherited lysosomal storage disease known as mucopolysaccharidosis-IIIA (MPS-IIIA), due to a deficiency of the enzyme heparan sulphatase, was reported in an 18-month-old male Huntaway dog (Jolly et al 2000 Jolly, RD, Allan, FJ, Collett, MG, Rozaklis, T, Muller, VJ and Hopwood, JJ. 2000. Mucopolysaccharidosis IIIA (Sanfilippo syndrome) in a New Zealand Huntaway dog with ataxia. New Zealand Veterinary Journal, 48: 144–148. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). He had developed normally but when presented with a history of progressive ataxia over the preceding month, had a high stepping, prancing gait and difficulty in jumping into a utility vehicle. In addition, he had started to defaecate in his kennel. Following diagnosis of the enzyme deficiency, the mutant heparan sulphatase gene was sequenced and a PCR/restriction enzyme diagnostic test developed, based on the mutation. This is capable of detecting both homozygous and heterozygous individuals (Yogalingam et al 2000 Yogalingam, G, Pollard, T, Gliddon, B, Jolly, RD and Hopwood, JJ. 2001. Identification of a mutation causing mucopolysaccharidosis type IIIA in New Zealand Huntaway dogs. Genomics, 79: 150–153. [Google Scholar]). 相似文献

Abstract Extract Oestrus ovis or nasal bot-fly, has larvae that are deposited as the first instar and develop in the nasal fossae and cranial sinuses of sheep, goats and some wild ruminants (Zumpt, 1965 Zumpt, E. 1965. Myiasisin Man and Animalsin the Old World London: Butterworths,. [Google Scholar]). Once the larvae have matured they are sneezed out and pupariate in the soil. Occasionally, humans are affected by ocular myiasis (ophthalmomyiasis) and more rarely, nasal myiasis (Macdonald et al, 1999 Macdonald, PJ, Chan, C, Dickson, J, Jean-Louis, F and Heath, A. 1999. Ophthalmomyiasis and nasal myiasis in New Zealand: a case series. New Zealand Medical Journal, 112: 445–457. [PubMed], [Web of Science ®] , [Google Scholar]). The presence of O. ovis in dogs is also a rare occurrence (Zumpt, 1965 Zumpt, E. 1965. Myiasisin Man and Animalsin the Old World London: Butterworths,. [Google Scholar]) and in such non-typical hosts it is usual for development of the larvae to proceed no further than the first instar. Exceptions have been noted in dogs, where third instar larvae were expelled (Lucientes et al, 1997 Lucientes, J, Ferrer-Dufol, M, Andres, MJ, Peribañez, MA, Gracia-Salinas, MJ and Castillo, JA. 1997. Canine myiasis by sheep bot fly (Diptera: Oestridae). Journal of Medical Entomology, 34: 242–243. [Google Scholar]) or recovered from the nasal cavity at necropsy (Luján et al, 1998 Luján, L, Vázquez, J, Lucientes, J, Pañero, JA and Varea, R. 1998. Nasal myiasis due to Oestrus ovis infestation in a dog. Veterinary Record, 142: 282–283. [Google Scholar]). 相似文献

Abstract A Short Communication was published in the October 2002 issue of the New Zealand Veterinary Journal entitled “An investigation of the safety of oral calcium formate in dairy cows using clinical, biochemical and histopathological parameters” (McIntyre and Weston 2002 McIntyre, LH and Weston, SJ. 2002. An investigation of the safety of oral calcium formate in dairy cows using clinical, biochemical and histopathological parameters. New Zealand Veterinary Journal, 50: 195–198.
