• Prevalence of scrapie infection in Great Britain: interpreting the results of the 1997-1998 abattoir survey [2].
• These feeder cells are usually collected from slaughterhouses from unknown serological status animals for caprine arthritis-encephalitis virus (CAEV) infection which is frequent in many regions of the world [3].
• Routine meat inspection of 1316 pigs at a slaughter slab in Lusaka showed that 20.6% of the pigs had cysticercosis whereas serological testing of 874 pigs at the same abattoir indicated that 56.6% were found to have circulating antigens of Taenia solium [4].
• In 1997/1998, an abattoir survey was conducted to determine the likely exposure of the human population to transmissible spongiform encephalopathy (TSE) infection in sheep submitted for slaughter in Great Britain. The survey examined brain material from 2809 sheep processed through British abattoirs [5].

High impact information on Abattoirs

• Ovaries were obtained from an abattoir and cumulus-oocyte complexes (COC) were aspirated from antral follicles into culture medium supplemented with 4 mg/ml BSA and 2mM 3-isobutyl-1-methylxanthine (IBMX) [6].

• Nineteen E. faecium strains isolated from chicken caecum samples, collected in slaughterhouses and highly resistant to vancomycin or gentamicin, were coresistant to erythromycin, and/or tetracyclines, and/or streptogramins, and/or avilamycin [8].
• In this study we have used the technique of fla typing (PCR-restriction fragment length polymorphism analysis of the flaA and flaB genes) to identify the sources of strains contaminating the carcasses of five campylobacter-positive and two campylobacter-negative broiler flocks during abattoir processing [9].
• Significant differences between the abattoirs were found for all compounds tested except amoxycillin [10].

Biological context of Abattoirs

• To establish a method for specifically detecting E. rhusiopathiae for practical applications, such as for the inspection of slaughterhouses, the feasibility of using primers derived from the DNA sequence coding for 16S rRNA in a PCR-specific detection system was investigated [11].
• Evaluation of an immunobiosensor for the on-site testing of veterinary drug residues at an abattoir. Screening for sulfamethazine in pigs [12].
• Bovine CL were collected from a local abattoir and classified according to stage of diestrus based on anatomical characteristics [13].
• Characterization of multidrug-resistance phenotypes and genotypes of Escherichia coli strains isolated from swine from an abattoir in Osaka, Japan [14].
• Cholecystokinin gene expression was analyzed in intestinal mucosa obtained from Holstein cows after slaughter either at a local abattoir or at our research facilities and compared with CCK gene expression in the biopsy samples collected from the cannulated animals [15].

Anatomical context of Abattoirs

• Spermatozoa collected from rams killed at the abattoir metabolized both [3H] androstenedione and [3H] DHEA but this capacity was dramatically reduced in spermatozoa collected from rams subjected to short-term anaesthesea [16].
• Oocytes collected from abattoir material were matured and fertilized in vitro on defined days with sperm stored for up to 11 days in a citrate-based commercial diluent [17].
• Over a period of 12 months, 1006 ovine and 1129 caprine genitalia were collected from an abattoir [18].
• By means of appropriate immunohistochemical and immunobiochemical techniques, the expression of HSP27, HSP72 and HSP73 within the epithelium of normal and pre-ulcerative (hyperkeratinized) mucosa of the pars oesophagea of abattoir pigs was assessed [19].

Associations of Abattoirs with chemical compounds

• The lipopolysaccharide (endotoxin) content in airborne dust samples from three different poultry slaughterhouses was determined with both the chromogenic Limulus amebocyte lysate assay and gas chromatography-mass spectrometry analysis of lipopolysaccharide-derived 3-hydroxy fatty acids [20].
• A study was conducted to determine the feasibility of performing "on-site" screening for sulfamethazine (SMT), at an abattoir, using a rapid immunobiosensor method [12].
• During the period 1984-1992, a total of 1051 samples of porcine kidney from 31 abattoirs were analysed for cadmium at the National Food Administration within the control programme for livestock production [21].
• A survey was conducted to determine the incidence of tetracycline antibiotic (TCAs) residues in the kidneys of slaughtered animals that did not pass inspection for human consumption by the Japanese Food Sanitation Law and the Meat Inspection Law at the slaughterhouses in Aichi Prefecture, Japan, from April 1985 to March 1998 [22].
• Pigs at abattoir Y had higher mean serum levels of CPK than pigs at abattoir X (3.63 log10 U/litre vs 3.41 log10 U/litre, 0.03 sed, P < 0.001), higher total LDH activities (1269.5 U/litre vs 922.8 U/litre, P < 0.001) and higher cortisol concentrations (1.70 log10 ng/ml vs 1.51 log10 ng/ml, P < 0.001) [23].

Gene context of Abattoirs

• The aim of the present study was to investigate COX-1 and COX-2 expression by immunohistochemical methods in 20 bovine urothelial carcinomas collected at public slaughterhouses from cows that had been suffering from chronic enzootic hematuria [24].
• The yopT gene was found in 99.1% of the farm isolates but in only 76.6% of the isolates found at the abattoir from the corresponding carcasses [25].
• Syntaxin 1B and GFAP were detected in many of the sponge samples taken along the slaughter line and in the chill rooms of all three abattoirs; GFAP was also detected in one sample of longissimus muscle (striploin) taken in the boning hall of one of the abattoirs but not in the other two abattoirs or in retail meats [26].
• The prevalence of yadA-positive Y. enterocolitica in fattening pigs increased from 1995 versus 1999; the mean prevalence in five slaughterhouses for the 2 years was 33% and 64%, respectively [27].
• In Expt 2, ovaries containing a young corpus luteum and with or without a large oestrogen-active follicle were collected from the abattoir [28].

Analytical, diagnostic and therapeutic context of Abattoirs

• Seroprevalence of Toxoplasma gondii in swine from slaughterhouses in Lima, Peru, and Georgia, U.S.A [29].
• Fresh bovine parietal tunica vaginalis sacs collected from an abattoir were processed and preserved by freeze-drying and by using 99.5% glycerol [30].
• Additional purification by density gradient centrifugation improved the viability of the abattoir liver group to a mean of 95% (trypan blue) [31].
• The mean viability in the intraoperative perfusion group was 65 +/- 14% (trypan blue) compared with a maximum viability of 39% in the abattoir liver group [31].
• The aim of the method described here is to remove hemoglobin, the major contaminant in the bovine plasma obtained from slaughterhouses, by adding a mixture of 19% cold ethanol and 0.6% chloroform, followed by fibrinogen and globulin precipitation by the Cohn method and nonspecific hemagglutinin by thermocoagulation [32].
