“…Coagulase-positive staphylococci other than S. aureus, such as Staphylococcus intermedius and Staphylococcus hyicus have been isolated from the commensal flora of skin and nasopharynx, as well as from infection sites of animals (Quinn et al, 2011) and can be responsible for sepsis (Casanova et al, 2011), nail bed infection (Pottumarthy et al, 2004), and wound infection (Osterlund et al, 1997;Kelesidis and Tsiodras, 2010) in humans following exposure to animals or the pathogens. More importantly, it was observed that coagulase positive Staphylococcus are found in larger proportion (58.1%) of sampled sources, particularly in 61.4% of samples from abattoir environment and 57.5% carcass.…”

Background: Foodborne bacterial pathogens and spoilage microbes leads to economic loss as a result of foods deterioration and public health risk. In areas where there is habit of raw meat consumption, various bacteria may result in acquire food-borne diseases and intoxication.Methods: A cross-sectional study was conducted to assess microbial contamination along Asella Municipal Beef Abattoir line. A total of 470 samples consisting of 400 beef carcasses swab and 70 environmental samples (apron, carcass splitting axil, personnel hand, hooks, knife, meat wrapping plastics, cleaning water) were collected and examined for presences of microbial. One colony type was characterized per positive samples, with no mixed microbial contamination report in this work. The isolation and identification of bacterial contaminates was performed according to the standard microbiological procedures. For E. coli, the hemolytic nature and appearance of metallic sheen on eosin methylene blue agar were used to define the pathogenicity. Additionally, rabbit plasma-based coagulase test was used to differentiate coagulase positive Staphylococcus (CPS) and coagulase negative Staphylococcus (CNS) as indication of pathogenicity.Results: Out of the total samples examined, 99.1% (95% CI= 97.8-99.8) were contaminated with bacteria. The observed proportion of beef abattoir line contamination was; Staphylococcus aureus (36.4%), CNS (16.2%), other grams positive isolates (14.0%), Staphylococcus hyicus (13.8%), and E. coli (10.9%), and Staphylococcus intermedius (7.9%). The total proportion of samples positive for coagulase positive (pathogenic) Staphylococcus species were 58.1% (95% CI= 53.5-62.6), with a 61.4% and 57.5% occurrence in abattoir environment and carcass samples, respectively. All sampling locations were found contaminated with S. aureus (34.3-60.0%) and E. coli (10.0-30.0%). All locations were contaminated with CNS (10.0-20.0%), except for carcass splitting axil. S. hyicus contaminated all location at rate of 10.0-30.0%, except the hooks and cleaning water. S. intermedius was observed only at carcass splitting axil (10.0%), cleaning water (10.0%) and carcass (8.0%). Other grams positive isolates were observed at 10.0-30.0%, but not on carcass splitting axil and hooks. The observed isolation rate of CPS (40-90%), S. aureus (30-60%), S. hyicus (0-30%), S. intermedius (0-10%), E. coli (10-30), and CNS (0-20) in different abattoir environment was higher than the isolation rate from carcass samples at proportion of 57.5%, 34.3%, 14.5%, 8.8%, 10.5, and 16.8%, respectively. Based on chi-square analysis S. aureus was significantly (p<0.05) higher in environmental (48.6%) than in meat (43.3%) samples. But the proportion of distribution with other isolates was insignificant (p>0.05) between environmental (2.9-12.9%) and meat (8.0-16.8%) samples.Conclusion: The finding indicates the presence of one or more zoonotic and spoilage bacterial pathogens in the beef abattoir which might lead to mixed foodborne infection and intoxication. Therefore, hygienic operations in the beef line; proper handling of working equipment’s and carcass; as well as the application of modern working facilities could reduce the risk of such microbial hazards associated with beef production in the abattoirs.

“…The difference in the prevalence percentages can also be attributed to the fact that the prevalence of S. saprophyticus changes seasonally and increases significantly at the end of summer [53]. We isolated three coagulase positive Staphylococci, S.aureus, S. intermedius, and S. hyicus (which was found to be MDR), but it is surprising that the second and third are related to dogs and pigs respectively [54,55], and there is no evidence, to the best of our knowledge, that it is part of the natural components of the human's urinary system. S. aureus exhibited significantly lower susceptibility (P≤0.05) to tetracycline, erythromycin, azithromycin, clindamycin, mupirocin, and fusidic acid than CONS.…”

Background: It has been established that the urinary tract is not sterile, however, research related to the study of urine bacteria are limited. Our work aims to study the frequency and patterns of resistance of normal urinary aerobic bacterial flora.Methods: Clean catch midstream urine specimens were collected from 120 young healthy females, and then cultured. Identification of bacteria and antimicrobial susceptibility were done by means of Biomérieux VITEK® 2 automated systems.Subjects who have undergone antimicrobial treatment in one month weren't included.Results: The incidence of positive bacterial cultures was 54.2%, of which 21.5% were ploymicrobial. 107 bacterial isolates that encompass 12 genera and 27 species that were predominated by Gram-positive bacteria (72%) were cultivated. Staphylococcaceae (46.1%) and Enterobacteriaceae (17.8%) were the most frequently isolates among Gram positive and Gram negative bacteria respectively, from them 36 species have been identified as b lactamase producers. The top four frequently isolated bacteria are Micrococcus species (16%), Staphylococcus haemolyticus (13.2%), Staphylococcus aureus (10%), and Klebsiella pneumoniae (10%). Twenty two bacterial species weresubjected to antimicrobial susceptibility testing by using broad and narrow spectrum antibiotics and antimicrobials. Ampicillin showed the lowest susceptibility rate against Gram positives, followed by erythromycin and azithromycin. The lesser antimicrobial susceptibility potential among Gram negative bacteria was exhibited against ampicillin, followed by piperacillin and cefotaxime. Conclusion:Our findings emphasize the importance of highlighting urine bacterial flora in research especially those related to susceptibility patterns, employing more advanced culture methods as multiple drug resistant bacteria were isolated.

The objective of this study was to investigate the causes of death and potential diseases carried by the wild-ranging carnivores in Taiwan through a government-supported disease survey program. During the period of August 2011 to January 2015, a total of 51 carcasses from rescued but dead or road-killed carnivores were necropsied for histopathology, molecular and immunological assays, microbiology, and parasitology. The cases included 31 Taiwan ferret badgers (TWFBs) (Melogale moschata subaurantiaca), 12 masked palm civets (MPCs) (Paguma larvate taivana), 5 small Chinese civets (SCCs) (Viverricula indica pallida), and 3 crab-eating mongooses (CEMs) (Herpestes urva). Zoonotic rabies and fatal canine distemper were diagnosed in four TWFBs and three MPCs, respectively. A high prevalence rate of lungworm infestation (23/31; 74.2%) was observed in TWFBs. In addition, a unique fatal Staphylococcus hyicus pneumonia and a fatal heavy systemic sarcopic mange infestation were diagnosed in a TWFB and a suckling MPC kid, respectively. Road tra±c accidents and stray dog-associated killing were the most common etiologies for the death of wild-ranging carnivores.
