2002: Hiatal hernia in a puppy     

Hunt GB  O'Brien C  Kolenc G  Malik R 《Australian veterinary journal》2002,80(11):685-686

A sliding hiatal hernia (where the terminal oesophagus, oesophagogastric junction and part of the stomach move cranially through a diaphragmatic defect) was diagnosed in a 4-month-old, Shar-Pei puppy presented for evaluation of regurgitation. The diagnosis was confirmed using radiography. Herniorraphy consisted of repositioning the stomach within the abdomen, plicating the diaphragmatic hiatus and performing a tube gastropexy to the left abdominal wall. Veterinary practitioners should have a high index of suspicion of hiatal hernia in young puppies, particularly Shar-Peis and British Bull Dogs, that present with persistent vomiting or regurgitation.  相似文献   

Polymerase chain reaction amplification of 16S-23S spacer region for rapid identification of Salmonella serovars     

Bakshi CS  Singh VP  Malik M  Sharma B  Singh RK 《Acta veterinaria Hungarica》2002,50(2):161-166

Polymerase chain reaction (PCR) was used to amplify the spacer regions between the 16S and 23S genes of rRNA genetic loci of Salmonella serovars for their rapid identification. These genetic loci revealed a significant level of polymorphism in length across the species/serovar lines. When the 16S-23S spacer region amplification products were subjected to agarose electrophoresis, the patterns observed could be used to distinguish all the serovars of Salmonella tested. Unique elements obtained in amplification products were mostly clustered at serovar level, although certain genus-specific patterns were also observed. On the basis of the results obtained, the amplification of 16S-23S ribosomal spacer region could suitably be used in a PCR-based identification method for Salmonella serovars.  相似文献   

Bacteriological warfare amongst cats: what have we learned about cat bite infections?     

Love DN  Malik R  Norris JM 《Veterinary microbiology》2000,74(3):179-193

Cat bite infections are one of the most common infectious diseases presenting to veterinary practices and to emergency rooms at human hospitals. This review describes the disease in humans and cats, the origin of organisms involved in cat bite abscesses and the importance of selected organisms such as members of the genus Porphyromonas in the disease. It also discusses future directions, the importance of identifying significant organisms and why an understanding of antimicrobial susceptibility patterns is of consequence to the outcome of the disease in humans and cats.  相似文献   

Cryptococcosis in Gilbert's and long-nosed potoroo     

R J Vaughan  S D Vitali  P A Eden  K L Payne  K S Warren  D Forshaw  J A Friend  A M Horwitz  C Main  M B Krockenberger  R Malik 《Journal of zoo and wildlife medicine》2007,38(4):567-573

Two cases of fatal cryptococcosis are described, one of Cryptococcus neoformans infection in a Gilbert's potoroo (Potorous gilbertii) and one of Cryptococcus gattii infection in a long-nosed potoroo (Potorous tridactylus). The diagnoses were confirmed by culture and specific immunohistochemistry, respectively. The long-nosed potoroo tested positive using the latex cryptococcal antigen test (LCAT), whereas the Gilbert's potoroo had a negative LCAT result despite having advanced disease of some duration. In both cases, the clinical presentation was a progressive neurologic disease associated with a central nervous system infection. Pulmonary infection was also observed in the long-nosed potoroo. Specific treatment with antifungal agents was unsuccessful in the long-nosed potoroo.  相似文献   

Kinetics of Interferon-Gamma Production and its Comparison with Anti-Listeriolysin O Detection in Experimental Bovine Listeriosis     

Barbuddhe SB  Malik SV  Choudhary SP  Gupta LK 《Veterinary research communications》1998,22(8):505-516

The kinetics of the production of interferon gamma (IFN-) in whole blood culture and its comparison with anti-listeriolysin O (ALLO) detection by ELISA were studied during oral infection of calves with Listeria monocytogenes. Culture filtrate antigen (CFA), listeriolysin O (LLO), and sonicated antigen (SA) were used to prime the peripheral blood mononuclear cells (PBMCs) and the plasma from orally infected calves. IFN- and ALLO appeared as early as day 7 of an oral infection. IFN- was detected earlier with LLO than with SA. The Max50 interleukin (IL-2) activity and IFN- estimated in the culture supernatant from PBMCs primed in vitro with different antigens of L. monocytogenes revealed high induction of IL-2 and IFN- by CFA, LLO and live antigen. IFN- assay and ALLO detection were used for testing cases of repeat breeding in dairy cattle. It appeared that detection of IFN- employing LLO can be used to diagnose listerial infections.  相似文献   

Bacterial discospondylitis in a cat     

R. Malik  M. Latter  D. N. Love 《The Journal of small animal practice》1990,31(8):404-406

A cat with hindlimb ataxia which progressed to paraplegia was found to have bacterial discospondylitis and a paravertebral abscess at necropsy. The infection had penetrated the vertebral canal. It is postulated that the vertebral infection occurred following haematogenous spread from a pneumonic focus.  相似文献

Tick paralysis in North America and Australia   总被引：1，自引：0，他引：1  

R Malik  B R Farrow 《Veterinary Clinics of North America: Small Animal Practice》1991,21(1):157-171

The pathophysiology and clinical manifestations of tick paralysis in North America and Australia are reviewed. Clinical and electrodiagnostic findings in tick paralysis are contrasted with those that occur in other diffuse lower motor neuron disorders, and the disease in North America is compared with the more severe form of the disease that occurs along the east coast of Australia. A detailed account of the treatment of animals afflicted with tick paralysis is presented.  相似文献   

Effects of Time and Rate of Nitrogen and Phosphorus Application on the Growth and the Seed and Oil Yields of Canola (Brassica napus L.)     

M. A. Cheema  M. A. Malik  A. Hussain  S. H. Shah  & S. M. A. Basra 《Journal of Agronomy and Crop Science》2001,186(2):103-110

A field study was conducted to investigate the influence of variable rates of application of N and P fertilizers in splits at various times on the growth and the seed and oil yields of canola (Brassica napus L.) during 1995–97. Rates of fertilizer application were 0 and 0 (F0), 60 and 0 (F1), 0 and 30 (F2), 60 and 30 (F3), 90 and 60 (F4) and 120 and 90 (F5) kg N ha^?1 and kg P₂O₅ ha^?1. All the P was applied at sowing while N was applied in splits, i.e. all at sowing, half at sowing and half with first irrigation, or half at sowing and half at flowering. The responses of growth, seed yield and components of yield were consistent in both years. Increasing the rate of fertilizer application from F4 (90/60 kg N/P₂O₅ ha^?1) to F5 (120/90 kg N/P₂O₅ ha^?1) increased the leaf area index (LAI) relative to the control and to lower rates of fertilizer application. For both crops, application of 90/60 kg N/P₂O₅ ha^?1 significantly enhanced total dry matter (TDM) and seed yield. Seed yield increased mainly due to a greater number of pods per plant and seeds per seed‐pod. The time of fertilizer application did not significantly affect seed yield or components of yield in either season. Oil yield generally followed seed yield, increasing with increasing rate of fertilizer application up to 90/60 kg N/P₂O₅ ha^?1. The maximum oil contents were obtained from the control. The results show that seed and oil yields of canola were maximized at the F4 (90/60 kg N/P₂O₅ ha^?1) rate of application under the agro‐ecological conditions of Faisalabad, Pakistan.  相似文献
