The using of antibiotics and antimicrobials drugs without control may leads to the development of numerous complications and resistance of microorganisms to antibiotics. The using of antibiotics and antimicrobials drugs should are controlled on poultry farms. That is why the monitoring and determination of sensitivity of bacterial diseases agents to antimicrobial drugs are very important. Results of salmonellas’ and kolibakterias’ monitoring in poultry’s farms of Ukraine are introduced in the article. Researches were conducted at the Department of veterinary sanitary examination, microbiology, zoohygiene and safety and quality of livestock products of Sumy NAU. Sampling for microbiological studies was conducted from the hatchery and from pathological material and premises where poultry of different age groups was held. The spread of the disease, morbidity, mortality, mortality rate, age characteristics, economic loss what diseases cause to the poultry farms were counted. Identification of Salmonella and Escherichia was conducted by ELISA with using of RIDASCREEN® and LOCATE® test systems, according to methodical recommendations of RIDASCREEN® and LOCATE® test systems using. The results were read visually or after addition of storageco with ELISA–photometer (reader) at 450 nm. Sensitivity to antibiotics was determined by disco – diffusion method in agar. Microbiological monitoring of a number of poultry farms in Ukraine has shown that agents of bacterial diseases’ are widely spread. Between the isolated microflora largest number were accounted for Salmonella (54.1%) and the Escherichia (30.8 per cent). The rest (15,1%) were isolated cultures of Proteus, Pseudomonas, Klebsiella, Salmonella, Campylobacteria, Enterobacteria, and Clostridia Citrobacter. This indicates that systematic control over the availability of the causative agents of bacterial infections in all critical points of production of poultry products is very necessary. Among isolates that were isolated from ill poultry and poultry objects, differences in their sensitivity to antimicrobial agents from active substances that officially have registered in our country were discovered. Bactericidal activity of relatively isolated cultures was showed by colistin, ftorfenicol, zeftiocur, TimTil 250, doxicyclin, enroxil and sarafloxacin.

Tract Infections

Background:Urinary tract infection is the most common bacterial infections in humans and serious health problem in many parts of the world. It has become more complicated in treatment due to different pathogens and increasing resistant to antimicrobial agents. This study aims to investigate the prevalence of urinary tract infection and antibiotic susceptibility patterns of pathogens among the patients attending in B & B hospital Nepal.Materials and Methods:A hospital based cross sectional study was conducted in between April 2010 to March 2011. Urine samples were collected from clinically suspected patients and tested bacteriologically using standard procedures. Antimicrobial susceptibility test was performed for isolated pathogen using the Kirby-Bauer disk diffusion method according to Clinical and Laboratory Standards Institute guidelines.Results:Out of 1260 examined specimens 25.24 % were positive and majority 61.64% were females.  The most common pathogens isolated were Escherichia coli (66.67%), Enterococcus (7.55%) and Staphylococcus (6.60 %). The drug resistant among the positive cases were reported. The highest resistant of positive cases was found with Cefexime (87.88%) and Enterococcus with Ampicillin (66.67%) and Staphyllococcus with Cloxacillin (66.67%). The highest susceptibility was for Vancomycin and Ampicillin i.e. 33.33% in each.Conclusion:The findings showed that E. coli isolates were the predominant pathogen and the presence of bacterial isolates with very high resistance to the commonly prescribed drugs. As drug resistance among bacterial pathogens is an evolving process and serious issue. Therefore, routine surveillance and monitoring studies should be conducted to provide physicians knowledge on the updated and most effective empirical treatment of UTIs. Asian Journal of Medical Sciences Vol.7(5) 2016 47-51

AbstractThere are several enteric bacterial diseases and conditions of pigs that require control to prevent overt disease, to reduce morbidity and mortality, and to improve the efficiency of production. Traditionally, veterinarians, feed manufacturers and producers have relied upon antibiotics and minerals (for example, ZnO, CuSO4) in diets for a large part of this control. However, recent trends, particularly in Europe, are to reduce antimicrobial use and seek alternative or replacement strategies for controlling enteric bacterial diseases. The majority of these strategies rely on ‘nutrition’, taken in its broadest sense, to reduce the susceptibility of pigs to these diseases. Evidence to date suggests that specific dietary interventions, for example feeding very highly-digestible diets based on cooked white rice, can reduce the proliferation of a number of specific enteric bacterial infections, such as post-weaning colibacillosis. No simple and universal way to reduce susceptibility to pathogens in the gastrointestinal tract has been identified, and the underlying basis for many of the reported positive effects of ‘nutrition’ on controlling enteric infections lacks robust, scientific understanding. This makes it difficult to recommend dietary guidelines to prevent or reduce enteric bacterial diseases. Furthermore, some diseases, such as porcine intestinal spirochaetosis caused byBrachyspira pilosicoli, are sometimes associated with other pathogens (co-infections). In such cases, each pathogen might have different nutrient requirements, ecological niches and patterns of metabolism for which a variety of dietary interventions are needed to ameliorate the disease. Greater understanding of how ‘nutrition’ influences gut epithelial biology and immunobiology, and their interactions with both commensal and pathogenic bacteria, holds promise as a means of tackling enteric disease without antimicrobial agents. In addition, it is important to consider the overall system (i.e. management, housing, welfare) of pig production in the context of controlling enteric bacterial diseases.

A cross-sectional study was carried out to determine antimicrobial drug resistance patterns of E. coli O157:H7 isolates and estimate the level of the pathogen. A total of 194 cloacae swab samples were collected randomly in two poultry farms. Standard cultural, biochemical, and serological (latex agglutination) methods were used to isolate E. coli O157:H7. The isolates were subjected to antimicrobial susceptibility testing using disc diffusion method. Out of 194 cloacae samples examined, 13.4% (n=26) were found to be positive for E. coli O157:H7. The finding indicated differences in E. coli O157:H7 infection among the different risk factors. Chicken from Adele Poultry Farm showed higher E. coli O157:H7 infection (OR = 3.89) than Haramaya University poultry farm and young birds had more infection (OR = 4.62) than adult birds. Of the total 14 antimicrobials included in the panel of study, the susceptibility results were varied with 96.15% and 0% E. coli O157:H7 isolates expressing resistance to erythromycin, clindamycin, spectinomycin, and ciprofloxacin, respectively. Multidrug resistance to more than two antimicrobial agents was detected in 24 (92.30%) of the isolates. The study showed high presence of antimicrobial resistant isolates of E. coli O157:H7. Further study is required to better understand the ecology and evolution of bacterial resistance to antimicrobial agents.

Background. Staphylocci are the leading pus-forming Gram-positive bacteria in the childrens hospitals. The prevalence of the antibiotic resistant strains among them limits therapeutic effects of infections in children. Aim. The research is aimed at characterizing the species of staphylococcus, which are isolated from the different clinical specimens of the patients at the clinics of Saint Petersburg State Pediatric Medical University in 2019, and analysis of their susceptibility to antimicrobial agents. Materials and metods. According to the clinical recommendations of 2018, susceptibility to antimicrobial drugs (AMD) was revealed in 860 strains of staphylococci determined by the disc diffusion method, which were identified by the automated analyser Vitek-2 compact. Results. Six species of staphylococci were represented at the hospital departments, among which Staphylococcus epidermidis prevailed in the departments of the neonate pathology department and intensive care units (63.0% and 46.2% respectively), Staphylococcus aureus is commonly found at the departments of surgery and the departments of the therapeutic profiles (61.7% and 46.2% respectively). More than a half of the staphylococci strains (63.0%) were resistant to at least one of the antimicrobial drugs. Vancomycin and line solid showed the highest activity to these staphylococci. High specific weight of multidrug resistant (MDR) bacteria (37.8%) and extensively drug resistant (XDR) strains of the phenotype (33.0%) was revealed. The level of antibiotic resistant strains was the highest in Staphylococcus haemolyticus (98.1%) and S. epidermidis (82.0%), while the specific weight of the resistant ones, MDR and XDR strains was extremely low among S. aureus (16.2%, 1.5% and 0.4 respectively), as well as in methicillin-resistant isolates (0.8%). Conclusions. A great variety of antibiotic resistance was revealed among the staphylococci. The prevalence of these strains in the pediatric hospitals requires constant local monitoring of the antibiotic resistant staphylococci.

Background: Abscess in camel is one of the most important bacterial infections. It causes anemia and emaciation, resulting in an economic loss due to carcass condemnation and a decrease in reproductive and production efficiency. Aim: This investigation aimed to isolate the bacteria from abscesses in camels and evaluate the antibacterial activity of Moringa oleifera extracts. Materials and Methods: Disk diffusion method and minimum inhibitory concentration were used for the evaluation of the antibacterial activity of M. oleifera extracts against isolated bacteria from camel abscesses. Results: The isolated bacteria were displayed relatively as follows: Corynebacterium pseudotuberculosis (30.4%), Staphylococcus aureus (25.8%), Escherichia coli (17.8%), Corynebacterium ulcerans (10.5%), Klebsiella pneumoniae (8.5%), Pseudomonas aeruginosa (8.5%), Micrococcus spp. (6.7%), Proteus vulgaris (5.2%), Citrobacter spp. (4.2%), and Staphylococcus epidermidis (1.7%). The drugs of choice for Corynebacterium isolates were ciprofloxacin and trimethoprim/ sulfamethoxazole, whereas amikacin, ciprofloxacin, gentamicin, neomycin, novobiocin, streptomycin, and vancomycin were for Staphylococcus isolates. Moreover, the ethanol extracts of M. oleifera showed higher antibacterial efficacy than the cold aqueous extracts. Conclusion: M. oleifera is considered one of the new infection-fighting strategies in controlling pyogenic bacteria responsible for camel abscesses.

In the present study, a total of 225 retail meat products (poultry meat, ground beef, and beef samples) were tested for the prevalence of Salmonella. Of these, 50 (22.2%) were positive for Salmonella. Overall, the pathogen was detected in 22 (29.3%) samples of poultry meat (n = 75), 16 (21.3%) samples of ground beef (n = 75), and 12 (16%) samples of beef (n = 75). The most common isolate was Salmonella enterica serovar Typhimurium (9.8%), followed by S. bongori species (8.9%) and S. enterica subsp. diarizonae (3.5%). The Salmonella strains isolated were also examined for antimicrobial resistance patterns and production of β-lactamase enzyme. The resistance levels of the isolates against 14 different antimicrobial agents were tested by the disk diffusion method. None of the strains exhibited resistance to cefotaxime, ciprofloxacin, norfloxacin, or levofloxacin. However, the highest resistance rates in the meat isolates were 64% each for ampicillin and cephazolin and 56% for amoxicillin–clavulanic acid. A total of 62% of the 50 Salmonella strains were multiresistant to three or more antimicrobial agents. The exhibited multiple resistance to four or more antimicrobial drugs was 32%. Furthermore, none of the isolates had β-lactamase enzyme activity.

Porcine pleuropneumonia, caused by Actinobacillus pleuropneumoniae is one of the most important bacterial diseases of the pig respiratory tract. One hundred and forty eight Actinobacillus pleuropneumoniae strains isolated from pig's clinical samples were tested for their susceptibility to 11 antimicrobials by disk diffusion method. Isolates were obtained from the pathoanatomically altered pig's lung that died with signs of respiratory disease. Antimicrobial discs with following concentration were used: ampicillin 10 µg, amoxicillin 10 µg, amoxicillin/clavulanic acid 20/10 µg, cefotaxime 30 µg, gentamicin 10 µg, penicillin 10 IU, streptomycin 10 µg, tetracycline 30 µg, enrofloxacin 5µg, lincospectin 15/200 µg, florfenicol 30 µg and trimethoprim/sulfamethoxazole 1.25/23.75 µg. Isolated strains showed various susceptibility to tested antimicrobials. Seventy-five percent of isolates were resistant to one or more drugs frequently used in the treatment of pig's diseases at farms in Serbia. All 148 isolates were susceptible to cefotaxime, enrofloxacin and florfenicol, while 96% of them were susceptible to amoxicillin/clavulanic acid and lincospectin. Susceptibility of isolates to amoxicillin, gentamicin and trimethoprim/sulfamethoxazole were 91%, 77% and 64%, respectively. The highest resistance rates were determined for tetracycline and streptomycin, 34% and 31%, respectively. When compared to our previous results, we noticed a decrease in resistance to tetracyclines and trimethoprim/sulfamethoxazole. Our results indicate that A. pleuropneumoniae strains isolated from pig's clinical samples in Serbia show high susceptibility to antimicrobial agents which are most often used in the pig industry.
