Contamination of locally fermented cow milk (Nono) by pathogenic bacteria constitute a major public health problem. This was because contaminated milk was a good medium that can support the growth and propagation of microbial pathogens. This study was designed to assess the bacteriological quality of locally fermented cow milk consumed in Maiduguri, northeastern Nigeria. Totally, forty (n = 40) samples of fresh, locally fermented cow milk (Nono) were collected and used in this study. Ten (10) milk samples each were collected from four randomly selected selling points (Monday Market, Custom Market, Kasuwan Shanu and Tashan Bama). The bacteriological quality of each milk sample were analysed using standard procedures for isolation, identification and enumeration of pathogenic bacteria. The mean total plate count ranged from 1.44x10 8 CFU/mL to 10.31x10 8 CFU/mL, while the mean total coliform count range from 0.57x10 8 CFU/mL to 11.17x10 8 CFU/mL. Statistically, there was a significant difference (p<0.05) in the mean total plate count and coliform count of milk samples collected from the four sampling points.Bacteriological culture and biochemical identification of all the isolates revealed Escherichia coli29(72.5%), Klebsiella specie3(7.5%), Salmonella specie 2(5%), Staphylococcus aureus 14(35%) and Streptococcus specie15(37.5%) respectively. All the results were above the acceptable limits (1.0 to 3.0 x 10 5 CFU/mL for total plate count and no coliform count per 100ml of milk sample) set by NAFDAC. Therefore the Nono products consumed in Maiduguri was not safe and wholesome for public consumption. Hence, the need to ensure the maintenance of standard hygienic protocols during the collection, storage, processing and marketing of locally fermented cow milk (Nono) in order to minimize microbial contamination.

The study was designed to assess the hygienic condition of local and imported tableegg-shell at Mosul markets. Two hundred local and imported eggs were randomlycollected from the markets and transferred immediately to the scientific research unitin the college of Veterinary medicine / University of Mosul for bacteriologicalexamination. Total counts using four types of medias were used: Standard Plate Countager (SPC), Mac Conkey ager, Violet Red Bile Glucose ager (VRBG) and TryptoneBile X-glucoronide (TBX) for Escherichia coli and fecal coliform bacteria. Resultsshowed that the means of total viable coliform and E. coli bacterial count in the localegg-shell at different markets ranged from 0.3 to 3 x107 on SPC agar, 0.08-10x107 onMac Conkey ager, 0.014-3x105 on (VRBG) and 0.3-7x104 on (TBX) compared with0.032-5x107 on SPC agar, 0.03-3.3x105 on Mac Conkey ager, 0.014-5.9x104 on(VRBG) with no growth on (TBX) for coliform and E. coli in the imported table-eggshell at different markets. Biochemical tests for local and imported table egg-shellwere performed. It was concluded that the rate of contamination in the local tableeggs was more than the imported one and the isolates of E. coli bacteria were obtainedonly from local eggs on the TBX medium.

OBJECTIVE To evaluate effects of laser treatment on incisional wound healing in ball pythons (Python regius). ANIMALS 6 healthy adult ball pythons. PROCEDURES Snakes were sedated, a skin biopsy specimen was collected for histologic examination, and eight 2-cm skin incisions were made in each snake; each incision was closed with staples (day 0). Gross evaluation of all incision sites was performed daily for 30 days, and a wound score was assigned. Four incisions of each snake were treated (5 J/cm2 and a wavelength of 980 nm on a continuous wave sequence) by use of a class 4 laser once daily for 7 consecutive days; the other 4 incisions were not treated. Two excisional skin biopsy specimens (1 control and 1 treatment) were collected from each snake on days 2, 7, 14, and 30 and evaluated microscopically. Scores were assigned for total inflammation, degree of fibrosis, and collagen maturity. Generalized linear models were used to investigate the effect of treatment on each variable. RESULTS Wound scores for laser-treated incisions were significantly better than scores for control incisions on day 2 but not at other time points. There were no significant differences in necrosis, fibroplasia, inflammation, granuloma formation, or bacterial contamination between control and treatment groups. Collagen maturity was significantly better for the laser-treated incisions on day 14. CONCLUSIONS AND CLINICAL RELEVANCE Laser treatment resulted in a significant increase in collagen maturity at day 14 but did not otherwise significantly improve healing of skin incisions.

Objective-To compare the recovery rates of Campylobacter fetus subsp venerealis (Cfv) from preputial scrapings of infected bulls with passive filtration on selective medium versus nonselective medium, with and without transport medium. Samples-217 preputial scrapings from 12 bulls (4 naturally and 8 artificially infected with Cfv). Procedures-Preputial scrapings were collected in 2 mL of PBS solution and bacteriologically cultured directly on Skirrow medium or passively filtered through 0.65-μm filters onto blood agar, with or without 24 hour preincubation in modified Weybridge transport enrichment medium (TEM). After 72 hours, plates were examined for Cfv and bacterial and fungal contamination or overgrowth. Results-Passive filtration of fresh preputial scrapings onto blood agar yielded significantly higher recovery rates of Cfv (86%) than direct plating on Skirrow medium (32%), whereas recovery from TEM was poor for both media (35% and 40%, respectively). Skirrow cultures without TEM were significantly more likely to have fungal contamination than were cultures performed with any other technique, and fungal contamination was virtually eliminated by passive filtration onto blood agar. Bacterial contamination by Pseudomonas spp was significantly more common with Skirrow medium versus passive filtration on blood agar, regardless of TEM use. Conclusions and Clinical Relevance-The use of transport medium and the choice of culture medium had significant effects on Cfv recovery and culture contamination rates from clinical samples. Both factors should be considered when animals are tested for this pathogen.

Objective-To compare Salmonella isolates cultured from feedyard and nonfeedyard (control) playas (ie, temporary shallow lakes) of the Southern High Plains. Sample Population-Water and muck (sediment) samples were obtained from 7 feedyard playas and 3 nonfeedyard playas in the winter and summer. Procedure-Each water and muck sample was enriched with sulfur-brilliant-green broth and incubated in a shaker at 37°C for 24 hours. A sample (100 mL) of the incubated bacterial-enriched broth was then mixed with 100 mL of fresh sulfur-brilliant-green enrichment broth and incubated in a shaker at 37°C for 24 hours. After the second incubation, a swab sample was streaked on differential media. Suspect Salmonella isolates were further identified by use of biochemical tests, and Salmonella isolates were confirmed and serovar determinations made. Results-Salmonella isolates were not recovered from the 3 control playas. Seven Salmonella enterica serovars were isolated from 5 of 7 feedyard playas in the summer, and 13 S enterica serovars were isolated from 7 of 7 feedyard playas in the winter. In the summer, 296 isolates were cultured, and 47 were Salmonella organisms. In the winter, 288 isolates were cultured, and 171 were Salmonella organisms. Conclusions and Clinical Relevance-Results indicated that feedyard playas are frequently contaminated with many Salmonella serovars. These pathogens should be considered whenever feedyard managers contemplate the use of water from these playas. Water from feedyard playas should not be used to cool cattle in the summer or for dust abatement.

The study was conducted for the purpose of investigating the intestinal bacterialcontamination in imported red meat and imported sausage. The study was carried out on 40samples of imported meat and 30 samples of sausage. The samples were collected fromdifferent areas in Basrah city (Al-Khaleej district, Al-Hayania, Al-Geneina, Five miles, Al-Ashar and Basra Market). Bacterial contamination in imported products (red meat andsausage)was investigated. In addition, total bacterial count for samples was done andcompared with specific control rates. Meat samples extracts were cultivated in differentdevelopmental and diagnostic media for the purpose of screening for bacterialcontamination mainly represented by coliform bacteria, Klebsiella pnumonia and Proteusspp. The results of the current study showed a high level of bacterial content in importedred meat and imported sausage, where the numbers of coliform bacteria, Klebsiellapneumonia and proteus spp above the permitted limit set by the Iraqi centralstandardization and quality.

OBJECTIVE To assess effects of photobiomodulation, silver sulfadiazine, and a topical antimicrobial product for the treatment of experimentally induced full-thickness skin wounds in green iguanas (Iguana iguana). ANIMALS 16 healthy subadult green iguanas. PROCEDURES Iguanas were anesthetized, and three 5-mm cutaneous biopsy specimens were obtained from each iguana (day 0). Iguanas were randomly assigned to 2 treatment groups, each of which had a control treatment. Wounds in the topical treatment group received silver sulfadiazine, a topical antimicrobial product, or no treatment. Wounds in the laser treatment group received treatment with a class 4 laser at 5 or 10 J/cm2 or no treatment. Wound measurements were obtained daily for 14 days. Iguanas were euthanized, and treatment sites were evaluated microscopically to detect ulceration, bacterial contamination, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity. RESULTS On day 14, wounds treated with a laser at 10 J/cm2 were significantly smaller than those treated with silver sulfadiazine, but there were no other significant differences among treatments. Histologically, there were no significant differences in ulceration, bacterial infection, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity among treatments. CONCLUSIONS AND CLINICAL RELEVANCE Photobiomodulation at 10 J/cm2 appeared to be a safe treatment that was tolerated well by green iguanas, but it did not result in substantial improvement in histologic evidence of wound healing, compared with results for other treatments or no treatment.

OBJECTIVE To evaluate pharmaceutical characteristics (strength or concentration, accuracy, and precision), physical properties, and bacterial contamination of fluconazole compounded products. SAMPLE Fluconazole compounded products (30- and 240-mg capsules; 30- and 100-mg/mL oral suspensions) from 4 US veterinary compounding pharmacies. PROCEDURES Fluconazole compounded products were ordered 3 times from each of 4 pharmacies at 7- or 10-day intervals. Generic fluconazole products (50- and 200-mg tablets; 10- and 40-mg/mL oral suspensions) served as references. Compounded products were evaluated at the time of receipt; suspensions also were evaluated 3 months later and at beyond-use dates. Evaluations included assessments of strength (concentration), accuracy, precision, physical properties, and bacterial contamination. Acceptable accuracy was defined as within ± 10% of the labeled strength (concentration) and acceptable precision as within ± 10%. Fluconazole was quantified by use of high-performance liquid chromatography. RESULTS Physical characteristics of compounded products differed among pharmacies. Aerobic bacterial cultures yielded negative results. Capsules (30 and 240 mg) had acceptable accuracy (median, 96.3%; range, 87.3% to 135.2%) and precision (mean ± SD, 7.4 ± 6.0%). Suspensions (30 and 100 mg/mL) had poor accuracy (median, 73.8%; range, 53.9% to 95.2%) and precision (mean ± SD, 15.0 ± 6.9%). Accuracy and precision were significantly better for capsules than for suspensions. CONCLUSIONS AND CLINICAL RELEVANCE Fluconazole compounded products, particularly suspensions, differed in pharmaceutical and physical qualities. Studies to evaluate the impact of inconsistent quality on bioavailability or clinical efficacy of compounded fluconazole products are indicated, and each study should include data on the quality of the compounded product evaluated.

Objective-To measure the relationship between gross lesions in swine carcasses observed at a processing plant and Salmonella contamination and to determine whether nonexpert assessments of lesion status would correspond with swine pathologists' judgments. Animals-Carcasses of 202 conventionally raised and 156 antimicrobial-free pigs in a Midwestern US processing plant examined from December 2005 to January 2006. Procedures-4 replicates were conducted. For each, freshly eviscerated carcasses were identified as having or lacking visceral adhesions by a nonexpert evaluator and digital carcass photographs were obtained. Swab specimens were obtained from carcasses before the final rinse stage of processing, and bacterial culture for Salmonella spp and Enterococcus spp was performed. Subsequently, carcass photographs were numerically scored for lesion severity by 3 veterinary pathologists. Results were used to test the ability of lesion detection to predict bacterial contamination of carcasses and the agreement between judgments of the inexperienced and experienced assessors. Results-The probability of Salmonella contamination in carcasses with lesions identified at the abattoir was 90% higher than that in carcasses lacking lesions, after controlling for replicate identity and antimicrobial use. The receiver operating characteristic curve and Cohen κ indicated close agreement between lesion detection at the abattoir and by the 3 pathologists. Conclusions and Clinical Relevance-Findings indicated the presence of lesions could be used to predict Salmonella contamination of swine carcasses and that a nonexpert processing-line assessment of lesions could be used to discriminate between healthy and chronically ill swine before their entry into the human food supply.
