Abstract Fish is the main source of animal protein for human diet. The aim of this study was to find out prevalence of pathogenic bacteria of two selected economically important fish of Pakistan namely Mahseer (Tor putitora) and Silver carp (Hypophthalmichthys molitrix). Live fish samples from hatcheries and dead fish samples from different markets of study area were randomly collected. The fish samples were analyzed for isolation, identification and prevalence of bacteria. The isolated bacteria from study fish were identified through biochemical test and about 10 species of pathogenic bacteria were identified including the pathogenic bacteria to human and fish namely, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. and Salmonella spp. The bacterial percentage frequency of occurrence in Silver carp and Mahseer fish showed Pseudomonas aeruginosa 21.42%, Staphylococcus epidermidis 17.85%, Escherichia coli 11.90%, Staphylococcus aureus 9.52%, Citrobacter spp. 9.52%, Serratia spp. 8.33%, Streptococcus iniae 7.14%, Stenotrophomonas spp. 5.95%, Bacillus spp. 4.76% and Salmonella spp. 3.57%. The study revealed that Fish samples of Mahseer and Silver carp that were collected from markets have found more isolates (10 bacterial species) than did the fresh fish pond samples (03 bacterial species) of hatcheries. The occurrence of pathogenic bacteria in study fish showed risk factor for public health consumers.

The present investigation attempted to evaluate the existence and survival of spoilage microorganisms in four common sea fishes (Poma, Rupchanda, Koral and Tuna) available in Bangladesh and to determine the effects of cooking temperature to optimize the growth of fish microflora. Moreover, the status of fish in frozen condition after cooking was also studied. A total 4 categories of sea fishes were collected from the local shops in Dhaka city. Raw, cooked and frozen fish samples were analyzed for the existence of pathogenic bacteria through the conventional cultural techniques and the confirmative biochemical identification procedures. Total viable bacteria were present in all four fish samples in raw, cooked and frozen condition up to 6 log CFU/mL. Most of the raw fish samples were found to harbor a huge population of microorganisms up to 5 log CFU/mL including the fecal coliforms. Several specific bacterial species like E. coli, Klebsiella spp., Salmonella spp., Shigella spp., Staphylococcus spp., Pseudomonas spp. and Vibrio spp. were present in raw samples. However, the microbial load reduced from the fish after cooking and the status was static in frozen condition. Thus, the incidence of fecal coliforms in raw fish may be considered as a serious threat to the public health upon consumption of such fishes.

The research was conducted on 19 stud farms in Serbia, on 80 mares used for breeding, with and without reproductive disorders. During the two years period (from 2009 to 2010) double guarded uterine swabs from 80 mares, aged between 3 and 22 years were collected. Mares belonged to the different breeds: Thoroughbred, Standardbred, Lipizzaner and mixed breeds. It was determined, that bacterial infection of genital organs was found in 24 mares in the examined population, and the bacterial species Streptococcus zooepidemicus was diagnosed in the 11 samples from cervical swabs. In the 5 samples, Escherichia coli was isolated, while Staphylococcus epidermidis and Pasteurella multocida were present in the 2 samples each, while the other causes and simultaneous isolation of two bacterial species are much less present. These species are: Bacillus spp. plus Escherichia coli; Streptococcus zooepidemicus plus Klebsiella pneumoniae and Escherichia coli plus Streptococcus zooepidemicus. In one swab we determinated Arcanobacter pyogenes. In this examination, according to available data after natural mating, we found conception level of 43,10%, which is similar with previous reports in our country.

The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba.  Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control.

This study aimed to evaluate the bactericidal activity of common disinfectants used for surfaces and medical devices. Sodium hypochlorite (D1), disinfectant (D2) composed of N-(3-aminopropyl)-N-dodecylpropane-1,3-diamine, chloride de didecyldimethylammonium, and disinfectant (D3) composed of Didecyldimethylammonium chloride and Polyhexamethylene biguanide hydrochloride, were tested against 15 strains isolated from the hospital environment and four reference bacteria. The microdilution method was performed to assess antimicrobial activity. The susceptibility was evaluated by comparing the minimum inhibitory dilution with the dilution of disinfectant recommended by the manufacture. D1 and D2 were active against Staphylococcus epidermidis, Staphylococcus saprophyticus, Enterobacter cloacae, Escherichia coli, Pseudomonas fluorescens, Methicillin-resistant Staphylococcus aureus, Bacillus spp, Corynebacterium spp, Gram-positive bacillus, Escherichia coli ATCC 25922, Bacillus subtilis ATCC 3366, and Pseudomonas aeruginosa ATCC 27853 strains but not active against Micrococcus spp, and Staphylococcus aureus ATCC 29213. D3 was ineffective against Micrococcus spp, Bacillus Gram Positive, Staphylococcus epidermidis, and Escherichia coli ATCC 25922. Therefore, D1 and D2 can eliminate most pathogenic bacteria in hospitals, in comparison to D3. It is necessary to monitor the antibacterial activity of disinfectants against reference strains but also against those usually present on surfaces. The obtained results could have promising applications in controlling the emergence of nosocomial infections.

The present study was carried out to assess the degree of microbiological proliferation in tannery wastes and the surrounding environment of the tannery industries. In this regard, a total of 8 tannery waste (n=4) and environmental (n=4) samples were tested. All the samples contained a huge load of bacteria and fungi in an average of 108 cfu/g or ml. An extended numbers of pathogenic bacteria were recovered. Among the pathogenic bacteria, Staphylococcus spp. was predominant. Most of the samples exhibited the presence of Pseudomonas spp. Salmonella spp. and fecal coliform were found each in one sample. Bacillus spp., Escherichia coli, Klebsiella spp. and Vibrio spp. were found in few samples. The average load of the pathogens was 104 cfu/g or ml. All the pathogenic isolates were found to be multidrug resistant. Higher resistance was found against penicillin and streptomycin. Tannery waste after lather treatment sample showed antibacterial activity against all the pathogens tested. Overall, presence of pathogenic microorganisms with multidrug resistance traits may pose serious public health threats. Stamford Journal of Microbiology, Vol.7(1) 2017: 14-18

Soil serves as an ecosystem for diverse microbes that perform various roles and that range from useful organisms in biological and geological processes to dangerous transmitters of diseases. Most type of soilborne bacteria are harmful to humans and causing severe problems. Klebsiella pneumoniae consider a serious nosocomial pathogen that cause pneumonia, UTIs, wound and liver abscesses. One hundred fifty (150) soil samples isolated randomly during the period November 2014- February 2015. Bacterium Klebsiella pneumoniae was the commonest pathogen (36.70%) followed by Staphylococcus aureus (22.78%), Staphylococcus epidermidis (12.65%), Bacillus spp. (10.12%), Pseudomonas aeruginosa (5.06%), Enterobacter cloacae (5.06%), Streptococcus spp.(2.53%), Citrobacter spp.(1.26%) and Pantoea spp.(1.26%) respectively. All K. pneumoniae isolates detected and confirmed by conventional PCR using rmpA gene size 530bp. The positive isolates were sequenced and search for homology. The multiple sequence alignment showed that our bacterial gene have differences in NAD-dependent epimerase and NAD (p)- binding domain sequence at different sites. The differences in the nucleotides at gene sequence for the isolated strain which may give new approach for developing higher sensitive K. pneumoniae strains and for better understanding of the rmpA gene structure that should provide new tools for disease management.

The pathogenic bacteria, Aeromonas hydrophila from naturally infected silver carp, Hypophthalmichthys molitrix were isolated and identified from a fish farm in Mymensingh. Fish showed motile Aeromonas septicemia (MAS) like reddish head and anal region, pale body colour and external haemorrhages. Intestine, liver, kidney and environmental samples such as sediment, feed and water were inoculated onto the Aeromonas isolation medium (AIM) and TSA plates. The AIM colonies were undergone specific characterization for Aeromonas hydrophila. Quantitative studies of bacterial flora of fish on TSA plates showed that the total bacterial load in intestine, liver and kidney of the sampled fish, sediment, feed and water of the environment were 1.00 × 105 to 1.50 × 105 CFU/g, 2.7 × 102 to 4.46 × 104 CFU/g, 1.00 × 103 to 2.17 × 103 CFU/g, 1.90 × 104 CFU/g, 4.10 × 103 CFU/g and 2.50 × 103 CFU/ml, respectively. After isolation, A. hydrophila was finally identified by their specific morphological, physiological and biochemical characteristics. They were gram negative, rod shaped, motile bacteria that showed positive reaction for oxidase and catalase, fermented glucose and were resistant to vibriostatic agent 0/129. They showed positive result in esculin hydrolysis test. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19943 J. Bangladesh Agril. Univ. 11(2): 373-376, 2013

AbstractThe aim of this study was the investigation of water, sediments and fish tissues contamination with heavy metals. All samples were taken from the Danube River in Belgrade region, a location upstream from Batajnica. Concentrations of Cd, Hg and Pb in water samples were not detected, while concentrations of Zn, Fe, Cu and As were in the range of 0.004 - 0.330 mg L-1. Iron was the most deposited metal in sediment samples in contrast to water samples where all investigated metals were detected. For the purpose of heavy metals determination in fresh fish tissue, fifteen samples of three different fish species, silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus carpio) and wels catfish (Silurus glanis) were collected. Concentrations of Pb, Cd, As and Hg were determined in the digestive tract, liver and muscle by absorption spectroscopy. The highest concentration of Pb was in the digestive tract in all three fish species, ranging from 0.036 to 1.518 μg g-1, while Cd was mostly deposited in the liver. Concentrations of As were in the range of 0.36 - 0.73 μg g-1in Hypophthalmichthys molitrix, 0.013 - 0.18 μg g-1in Cyprinus carpio and 0.003 - 0.005 μg g-1in Silurus glanis tissues, while the content of Hg was equal in all tested tissues of carp. Concentrations of all metals were found to be present in the fish samples at different levels, but these values are under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia, so the fish meat is acceptable for the human consumption.
