The ear discharge of fifteen dogs was examined for cytological and microbiological evaluation along with antibiotic sensitivity testing. The ear discharge of ten healthy dogs was also analyzed for comparative data. Cytological analysis showed that inflammatory cells and rod shaped organisms in highly infected cases. Otic microbiota in healthy cases revealed Bacillus spp. and Staphylococcus spp., while in clinical cases Pseudomonas spp., E coli, Klebsiella spp. and Alcaligenes spp., were also identified by using universal primer 16S rRNA PCR. The yeast Malassezia pachydermatis was isolated from ear discharge of all dogs. Among the anti – microbial drugs tested, Gentamicin had the most effective response against the otic microbes, followed by ciprofloxacin while neomycin had the least

The research work was conducted to isolate & characterized the bacteria isolated from mid-stream urine of human. A total of 30 samples were collected from patients with urinary tract infection (n=10samples); diabetic patients (n=10samples) & apparently healthy individuals (n=10samples). Escherichia coli, Staphylococcus spp. and Bacillus spp. was the predominant bacterial flora of human urine. Among the isolates, the prevalence of Escherichia coli was highest (80%) compared to Staphylococcus spp.(14%) and Bacillus spp.(6%). E. coli isolated from 6 different sources were found to be highly virulent, moderately virulent, less virulent and avirulent categories as observed in day-old suckling mice. Antibiotic sensitivity profiles suggest that nalidixic acid will be the first drugs of choice to treat the UTI caused by E. coli and arythromycin, ampicillin and azithromycin will be the second drugs of choice to treat the UTI caused by Staphylococcus spp and Bacillus spp. respectively.

Isolation and characterization with antibiotic sensitivity of the bacteria in the eye swab of 34 keratoconjunctivitis affected cattle were carried out on the basis of their morphology, staining, cultural and biochemical properties during the period from October 1999 to March 2000. Staphylococcus spp. (76.5%), Streptococcus spp. (38.2%), E. coli (52.9%), Bacillus spp. (70.6%), unidentified Gram positive cocci (5.9%) and unidentified Gram negative rods (20.6%) were identified as a single or mixed infection. Pathogenicity study of these isolated organisms showed conjunctivitis associated with Staphylococcus spp., Streptococcus spp., Bacillus spp. and E. coli in experimentally inoculated mice whereas unidentified Gram positive cocci did not show any conjunctivitis in mice. The mixed intraocular inoculation of these isolated bacteria produced severe keratoconjunctivitis within 24 hours both in mice and calves. Results of antibiotic sensitivity test showed that all types of bacterial isolates were found highly sensitive to oxytetracyclin (80-100%) and chloramphenicol (70-100%). Staphylococcus spp., Streptococcus spp. and Bacillus spp. were moderately susceptible to streptomycin (69.56%), trisulfa (60%) and trisulfa (80%) respectively. It may be concluded that among the tested antibiotics, oxytetracyclin may have the preference in clinical therapy of keratoconjunctivitis in cattle caused by bacteria in Bangladesh.

Overuse of antimicrobials in livestock health and production beyond therapeutic needs has been highlighted in recent years as one of the major risk factors for the acceleration of antimicrobial resistance (AMR) of bacteria in both humans and animals. While there is an abundance of reports on AMR in clinical isolates from humans, information regarding the patterns of resistance in clinical isolates from animals is scarce. Hence, a situational analysis of AMR based on clinical isolates from a veterinary diagnostic laboratory was performed to examine the extent and patterns of resistance demonstrated by isolates from diseased food animals. Between 2015 and 2017, 241 cases of diseased livestock were received. Clinical specimens from ruminants (cattle, goats and sheep), and non-ruminants (pigs and chicken) were received for culture and sensitivity testing. A total of 701 isolates were recovered from these specimens. From ruminants, Escherichia coli (n = 77, 19.3%) predominated, followed by Staphylococcus aureus (n = 73, 18.3%). Antibiotic sensitivity testing (AST) revealed that E. coli resistance was highest for penicillin, streptomycin, and neomycin (77–93%). In addition, S. aureus was highly resistant to neomycin, followed by streptomycin and ampicillin (68–82%). More than 67% of E. coli isolates were multi-drug resistant (MDR) and only 2.6% were susceptible to all the tested antibiotics. Similarly, 65.6% of S. aureus isolates were MDR and only 5.5% were susceptible to all tested antibiotics. From non-ruminants, a total of 301 isolates were recovered. Escherichia coli (n = 108, 35.9%) and Staphylococcus spp. (n = 27, 9%) were the most frequent isolates obtained. For E. coli, the highest resistance was against amoxicillin, erythromycin, tetracycline, and neomycin (95–100%). Staphylococcus spp. had a high level of resistance to streptomycin, trimethoprim/sulfamethoxazole, tetracycline and gentamicin (80–100%). The MDR levels of E. coli and Staphylococcus spp. isolates from non-ruminants were 72.2 and 74.1%, respectively. Significantly higher resistance level were observed among isolates from non-ruminants compared to ruminants for tetracycline, amoxicillin, enrofloxacin, and trimethoprim/sulfamethoxazole.

Fifty-one ready-to-eat street foods, 18 dishwater, and 18 surface swab samples were collected from six vendors in Johannesburg, South Africa. Food temperatures were recorded at the time of sampling. Standard methods were used to determine aerobic plate counts (APCs), spore counts (SCs), and Enterobacteriaceae counts (ECs) for food samples as well as coliform counts (CCs) for water and swab samples. In addition, Petrifilm Escherichia coli count (PC) plates were used for the enumeration of coliforms in food, water, and swab samples. The presence of selected foodborne pathogens in the food samples as well as the presence of nonpathogenic E. coli 1 (in food and water samples) was also tested for. Predominant colonies isolated from APC plates were characterized to the genus level. Holding temperatures for cooked meats and gravies ranged from 42.0 to 94.0°C, and those for uncooked salads ranged from 29.0 to 39.0°C. Mean APC values of 3.4 (±0.4) log CFU/g, 4.0 (±1.2) log CFU/ml, and 2.1 (±0.4) log CFU/25 cm2 were obtained for food, water, and swab samples, respectively. Mean SC values of 1.6 (±0.2) log CFU/g and 1.5 (±0.3) log CFU/25 cm2 were obtained for food and swab samples, respectively. A mean EC value of 2.0 (±0.4) log CFU/g for food samples and mean CC values of 2.5 (±0.3) log CFU/ml and 1.3 (±0.3) log CFU/25 cm2 for water and swab samples, respectively, were determined. Mean PC values of 1.6 (±0.1) log CFU/g, 1.9 (±0.6) log CFU/ml, and 1.4 (±0.4) log CFU/25 cm2 were determined for food, water, and swab samples, respectively. Bacillus cereus was detected in 22%, Clostridium perfringens in 16%, Salmonella spp. in 2%, and E. coli (non-O157:H+) in 2% of the 51 food samples. E. coli was found in 14 water samples (78%) and in 3 food samples (6%). Campylobacter spp., Listeria monocytogenes, Staphylococcus aureus, Vibrio cholerae, and Yersinia enterocolitica were also tested for in the food samples, but they were not detected. The 340 isolates obtained from APC plates for food, water, and swab samples were predominantly Bacillus spp., Micrococcus spp., and Staphylococcus spp. for all three sample types. It was concluded that the foods analyzed in this study were of acceptable quality and safety.

This study assessed the bacterial quality of fresh fruit juices sold in some restaurants in Port Harcourt, Nigeria. A total of twenty (20) fruit juice samples were collected from four (4) different types of fruit juices sold at four (4) different restaurants. The fruits that were used for this study are: Orange, Watermelon, Pineapple and Tiger nuts. Samples of the fruit juices were collected for bacteriological assessment using heterotrophic plate count and most probable number techniques, while CHRO Magar for E. coli and other coliforms was used for the detection of E. coli. The results showed that E. coli, Bacillus spp, Klebsiella spp, Streptococcus spp and Staphylococcus spp were present in the fruit juices. The results of the heterotrophic plate count showed that the bacterial count ranged from 2.7 x 102 (Orange) to 7.1 x 103 (Tiger nuts), while the results of the total coliform count ranged from 11 MPN/100 ml to 28 MPN/100 ml. However, the study revealed that the total E. coli count ranged from 0 to 7. The number of E. coli in each of the fruit juices and restaurants ranged from 6 to 13, Bacillus spp 12 to 19, Klebsiella spp 4 to 10, Streptococcus spp 6 to 11 and Staphylococcus spp 4 to 13. Bacillus spp had the highest percentage (31.4%), followed by Staphylococcus spp (20.1%). The highest percentage of bacteria was recovered from Tiger nuts (29.4%), followed by Watermelon (28.4%). Regular monitoring of the quality of fresh fruit juices sold in restaurants in Port Harcourt and other parts of Nigeria should therefore be enforced.

Two cases of granulomatous colitis in two French bulldogs were found to be unresponsive to fluoroquinolones. The granulomatous colitis diagnosis was made on the basis of PAS-positive histiocytes in the lamina propria of the colonic mucosa in biopsy samples taken at colonoscopy. Remission of granulomatous colitis has been reported using fluoroquinolones leading to the idea that invasive Escherichia coli strains in the colonic mucosa are involved. Oral enrofloxacin (Baytril 150 mg, Bayer, Spain) at 10 mg/kg per day for eight weeks was prescribed to both dogs in this study. A first course of therapy resolved the problem in dog No. 1, which, however, was followed by relapse three months later without enrofloxacin response. No clinical remission was seen in dog No. 2 and 4.4 mg/kg marbofloxacin (Marbocyl P 20 mg, Vetoquinol, Spain) per day for 10 weeks was administered but without any response. From both dogs, biopsy samples from the colonic mucosa were taken during colonoscopy. Samples were homogenised for microbial culture in different agar media to identify invasive microbes. Escherichia coli were largely isolated and antibiotic sensitivity testing (MIC of E. coli to selected antimicrobials, CLSI 2013) was carried out. In both cases, E. coli was resistant to fluoroquinolones. In dog No. 1 E. coli was susceptible to amoxicillin-clavulanate, cefazolin, amikacin and gentamicin whereas in dog No. 2 it was susceptible to doxycycline and amoxicillin-clavulanate. Clinical remission was achieved in dog No. 1 with amoxicillin-clavulanate (Synulox 250 mg, Pfizer, Spain) therapy for eight weeks. No response was found in dog No. 2 with any of the antimicrobials alone or combined with metronidazole.

Urinary tract infection (UTI), is defined as a disease caused by invasion of urinary tract by microorganisms. Majority of UTI cases are due to bacterial infection constitute about 95% of total UTI cases. About 80% of UTI cases are caused by E.coli producing extended spectrum ?-lactamase (ESBL) producing isolates. In recent years limitations in treating infections caused by multidrug resistant organisms has increased. This study aims to determine ESBL production of E. coli cases from a tertiary care hospital. Methodology: A total 358 midstream urine samples were collected by random sampling method during March 2015 to June 2018. Identification, antibiotic sensitivity testing, performed according to standard protocol following Clinical and Laboratory Standard Institute (CLSI) guidelines, 2013. Screening for ESBL producing E.coli isolates performed using ceftazidime further confirmation done by phenotypic disc diffusion test using combined disc method using ceftazidime (30µg) & ceftazidime/ clavulanic acid (30/10 µg) as per CLSI guidelines. Results: Total 358 specimens processed for urine culture. Gram negative bacilli isolated from 123(34.35 %), out of which 68 (55.28%) were E.coli, 19 (15.44%) K. pneumoniae, 15 (12.19%), Pseudomonas spp. 08 (6.50%), Citrobacter spp and Acinetobacter spp, 03 (2.43%), Proteus mirabilis, 01 (0.81%) Proteus vulgaris and Enterobacter respectively. Out of 68 isolates of E.coli, 65 (95.58%) were MDR, ESBL was detected in 31 (47.69%) out of these 65 isolates. Out of these 31 cases 19 (61.29%) were female and 12 (38.70%) were male cases. Conclusion: This study concludes 47.69% ESBL producing MDR E. coli were isolated from UTI cases with female predominance.

The present study was conducted on the rural dairy cows to detect the bacterial species from clinical mastitis in dairy cows with their antibiogram studies during the period from January 2015 to June 2015. For this purpose two upazilla were selected under the Nilphamari district. On the basis of morphology, staining, cultural and biochemical characteristics, the isolated organisms were classified as, Staphylococcus spp., Streptococcus spp., E. coli, and Bacillus spp. .For this study, a total of 48 samples were collected from affected mastitis cows. Out of 48 milk samples, 17 were positive for Staphylococcus spp. (35.42%), 9 were positive for Streptococcus spp. (18.75%), 7 were positive for E. coli (14.58%), 5 were positive for Bacillus spp.(10.41%),5 were positive for mixed organisms (10.41%) and 5 were unidentified organisms (10.41%). Antibiogram studies revealed that all of the isolates of Staphylococcus spp. were sensitive to gentamicin and were resistant to streptomycin. Gentamicin was sensitive to all of the isolates of Streptococcus spp. and was resistant to streptomycin. The isolates of Bacillus spp. were sensitive to ciprofloxacin and Bacillus spp. was resistant to streptomycin. All of the isolates of E. coli were sensitive to ciprofloxacin the isolates were resistant to ampicillin and amoxicillin. Over all sensitivity revealed that ciprofloxacin, gentamicin and enrofloxacin were most efficacious. Thus, it may be recommended that ciprofloxacin, gentamicin and enrofloxacin in optimum doses would resolve most cases of clinical mastitis in dairy cows.Asian J. Med. Biol. Res. December 2016, 2(4): 656-663
