Abstract The aim of this study was to evaluate three combinations of antibiotics applied perorally prior to laparotomy and gastrointestinal surgery and to select the most favorable combination. Research was performed on 24 female and male dogs divided into four groups. Following abdominal wall incision the caecum was compressed manually and 5 mL of saline solution was injected into it. Five mL of caecum contents was aspirated in a sterile syringe and only 0.1 mL was incubated into blood agar and homogenous agar. Bacterial colonies were counted and determined. Prior to surgery the control group (n=6) received no antibiotics. The group which received the combination of gentamicin and clindamycin (n=6) achieved the best reduction of E. coli whereas Enterococcus faecals was 100% destroyed. The group which received amoxicillin with clavulanic acid and metronidazole (n=6) acquired a reduction of bacteria Enterococcus faecalis, which could be sufficient for prophylaxis. The combination of gentamicin and erythromycin (n=6) failed to accomplish a reduction of the number of bacteria.

AbstractThe aim of this study was to determine the percentage of participation of particular species of microorganisms, isolated from the uterus of cows with endometritis and from cows without inflammatory lesions of the uterus, in the same postpartum period. The aim of the study was also to examine how long after parturition non-treated endometritis persists. Moreover, antibiotic susceptibility tests were carried out of the bacterial isolates dominating in the uterus. Forty cows were included in the study: 20 cows with endometritis (experimental group) and 20 cows without any inflammatory condition of the uterus (control group). The material for cytological and bacteriological tests was collected on the 5th, 26th, 40thand 60thday after parturition, using an intrauterine brush adapted for cows. The total number of collected isolates was 149, including 120 isolates from the uterus of cows with endometritis and 29 isolates from the uterus of cows without endometritis. The following species of microorganisms were isolated from the material collected from cows with endometritis: T. pyogenes (49.2%), E.coli (22.5%), F. necrophorum (11.7%), Staphylococcus sp. (6.7%), B. melaninogenicus (5.8%), and Streptococcus sp. (4.1%). The participation percentage of particular species of bacteria in the material collected from the uterus of cows without endometritis was as follows: T. pyogenes (27.6%), E.coli (24.2%), Staphylococcus sp. (20.7%), Streptococcus sp. (20.7%), B. melaninogenicus (3.4%) and F. necrophorum (3.4%). The highest percentage of T. pyogenes isolates was susceptible to ceftiofur (89.6%); cefoperazone (85.1%) and amoxicillin combined with clavulanic acid (79.1%). E. coli isolates were most susceptible to amoxicillin combined with clavulanic acid (100%), cefoperazone (94.1%) and oxytetracycline (82.3%).

Salpingitis is manifested as hemorrhagic follicular inflammation exudations and peritonitis, leading to reduced egg production and high culling of breeder flocks. From 2018 to 2021, increasing salpingitis during egg peak is threatening the poultry industry post-artificial insemination, both in breeder layers and breeder ducks across China. In our study, Escherichia coli (E. coli), Enterococcus faecalis (E. faecalis) and Chlamydia psittaci (C. psittaci) were isolated and identified from the diseased oviducts using biochemical tests and PCR. To identify and isolate pathogenicity, we inoculated the isolates into laying hens via an intravaginal route. Later, laying hens developed typical salpingitis after receiving the combination of the aforementioned three isolates (1 × 105 IFU/mL of C. psittaci and 1 × 106 CFU/mL of E. faecalis and E. coli, respectively), while less oviduct inflammation was observed in the layers inoculated with the above isolate alone. Furthermore, 56 breeder ducks were divided into seven groups, eight ducks per group. The birds received the combination of three isolates, synergic infection of E. coli and E. faecalis, and C. psittaci alone via vaginal tract, while the remaining ducks were inoculated with physiological saline as the control group. Egg production was monitored daily and lesions of oviducts and follicles were determined post-infection on day 6. Interestingly, typical salpingitis, degenerated follicles and yolk peritonitis were obviously found in the synergic infection of three isolates and the birds inoculated with C. psittaci alone developed hemorrhagic follicles and white exudates in oviducts, while birds with E. faecalis or E. coli alone did not develop typical salpingitis. Finally, higher E. coli loads were determined in the oviducts as compared to E. faecalis and C. psittaci infection. Taken together, the combination of E. coli and E. faecalis, and C. psittaci could induce typical salpingitis and yolk peritonitis both in laying hens and breeder ducks. Secondary infection of E. coli and E. faecalis via artificial insemination is urgently needed for investigation against salpingitis.

PURPOSE: Evaluate the effects of bromopride on abdominal wall healing of rats with induced peritoneal sepsis after segmental colectomy and colonic anastomosis. METHODS: Forty rats underwent sectioning of the left colon and end-to-end anastomosis and were divided into two groups of 20 animals for the administration of bromopride (bromopride group - B) or saline solution (control group - C). Each group was divided into subgroups of 10 animals each to be killed on the third (GB3 and GC3) or seventh postoperative day (GB7 and GC7). It was analyzed the following characteristics: breaking strength of the abdominal wall's wound; surgical and histopathological features of the abdominal wall; and clinical features of the rats. RESULTS: There was no difference between the groups in relation to the weight of the rats and the breaking strength of the abdominal wall's wound. The GB7 group presented less edema and less quantity of fibrin during histopathological evaluation compared to the GC7 group. CONCLUSION: Bromopride did not have harmful effects on the healing of abdominal wall in rats.

The purpose of this non-random retrospective cohort study was to evaluate the impact of prophylactic antibiotic on early outcomes including postoperative pain, swelling, bleeding and cyanosis in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 males, 30 females) whose dental implant placement were completed, included to the study. Patients used prophylactic antibiotics were defined as the experimental group and those who did not, were defined as the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 h preoperatively and 1 g amoxicillin + clavulanic acid twice a day for 5 days postoperatively while the control group had received no prophylactic antibiotic therapy perioperatively. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration and implant failure were analyzed on postoperative days 2, 7, and 14 and week 12. No statistically significant difference was detected between the two groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 ( p >0.05), while the severity of pain and swelling were greater on day 2 compared to day 7 and 14 and week 12 in both groups ( p =0.001 and p <0.05, respectively). Similarly, no significant difference was found between the two groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the two groups with regard to the percentage of flap dehiscence assessed at other time points. Within limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized control clinical studies with higher numbers of patients and implants are needed to substantiate our findings.

Aim. To study the influence of deproteinized dialysate from blood of milk-fed calves on the type of exudative discharge and dynamics of inflammatory reaction after hernia repair with plastics of the anterior abdominal wall with hernioendoprosthesis of polypropylene. Materials and Methods. The study involved 59 patients being on stationary treatment in the surgical department of Kursk Regional Clinical Hospital. Patients were hospitalized for the herniation of small or medium dimension. The patients were divided to two groups: the main (n=30) and control (n=29) groups. After endoprosthetics, the patients of the control group were given complex conservative treatment. The patients of the main group, besides standard treatment, were administered deproteinized dialysate from blood of milk-fed calves intravenously in drips 10 ml + 200 ml of 0.9% sodium chloride solution within 7 days. For cytological examination and determination of the type of cytograms, the traumatic discharge was collected and analyzed using the method of M.F. Kamaev and M.A. Palthsev. Results. Cytomorphometric examination was conducted on the third, fifth and seventh day after endoprosthetics with the aim of studying dynamic changes. Determination of cell composition and also of its changes characteristic of each studied period, was necessary for obtaining further information characterizing inflammatory process in the region of placement of the endoprosthesis. After endoprosthetics in patients who were administered hemodialysate, the inflammatory reaction was less pronounced than in patients who did not receive the preparation. This was associated with a more dynamic change of stages of the inflammatory process. In patients of the main group who received deproteinized dialysate, regenerative type of inflammation first appeared on the fifth day and made 6.9%; by the seventh day the share of patients with the regenerative type rose to 17.5%, while in the patients of the control group no regeneration stage was observed in both periods. Conclusion. Analysis of the efficiency of influence of hemodialysate on the inflammatory reaction in plastics of the anterior abdominal wall with polypropylene endoprosthesis evidences faster course of all stages of inflammation and reduction of its intensity by 10%.

ABSTRACT: The present study evaluated the efficacy of a single oral dose of doramectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. Sixteen adult rabbits were selected and distributed in two experimental groups. The treated group received 200 μg/Kg of oral doramectin and the control group received the same volume of saline solution. The diagnosis of the mites was made with a stereoscopic microscope. Hairs from the dorsal part of the neck, lumbar right, lumbar left, ventral side of the tail and ventral abdomen were evaluated for L. gibbus, and ear wax evaluated for P. ovis. The evaluation of the efficiency and the clinical assessment of the lesions was made in days 0, +3, +7, +14, +21, +28, and +35 after treatment. An efficacy of 75% and 87,5% was observed for L. gibbus in days +3 and +7 after treatment, an efficacy of 100% was observed in days +14, + 21, +28 e +35. An efficacy of 100% for the control of P. ovis was observed following day +7. The clinical lesion score of the control group remained unaltered, except for one animal which conditions worsened during experimentation. In the treated group animals, regression of the lesions was observed following day +3, and on day +21 no signal of infestation by P. ovis was present. None of the animals from the treated group presented secondary collateral effects caused by the doramectin, which proved itself as an optimal alternative for mite control in naturally infested rabbits.

The infection of Enterococcus faecalis and its interacting microorganisms in the root canal could cause persistent apical periodontitis (AP). Antibacterial root canal sealer has favorable prospects to inhibit biofilms. The purpose of this study was to investigated the antibacterial effect of root canal sealer containing dimethylaminododecyl methacrylate (DMADDM) on persistent AP in beagle dogs for the first time. Persistent AP was established by a two-step infection with Enterococcus faecalis and multi-bacteria (Enterococcus faecalis, Lactobacillus acidophilus, Actinomycesnaeslundii, Streptococcus gordonii). Root canal sealer containing DMADDM (0%, 1.25%, 2.5%) was used to complete root canal filling. The volume of lesions and inflammatory grade in the apical area were evaluated by cone beam computer tomography (CBCT) and hematoxylin-eosin staining. Both Enterococcus-faecalis- and multi-bacteria-induced persistent AP caused severe apical destruction, and there were no significant differences in pathogenicity between them. DMADDM-modified sealer significantly reduced the volume of periapical lesion and inflammatory grade compared with the control group, among them, the therapeutic effect of the 2.5% group was better than the 1.25% group. In addition, E.faecalis-induced reinfection was more sensitive to the 2.5% group than multi-bacteria reinfection. This study shows that root canal sealer containing DMADDM had a remarkable therapeutic effect on persistent AP, especially on E. faecalis-induced reinfection.

The role of the air as a vehicle of bacteria dissemination in the farming environment has been previously reported, but still scarcely studied. This study investigated the bacteria density/diversity of the inside and outside air and of litter samples at a broiler farm. Samples were collected considering two seasons, three outside air distances (50/100/150 m) and the four cardinal directions. Selective media was used for staphylococci, enterococci, and Enterobacteriaceae recovery. A high number of bacteria was detected in the litter (2.9 × 105–5.8 × 107 cfu/g) and in the inside air (>105 cfu/m3), but a low emission of bacteria was evidenced in the outside air (<6 cfu/m3). Moreover, the bacteria detected in the farm’s outside air decreased the further from the farm the sample was taken. A total of 544 isolates were identified by MALDI-TOF (146 from the litter, 142 from inside air and 256 from outside air). From these, 162 staphylococci (14 species; S. saprophyticus 40.7%), 176 Enterobacteriaceae (4 species; E. coli 66%) and 190 enterococci (4 species; E. hirae 83%) were detected. E. hirae was the predominant species, and identical PFGE clones were detected in inside and outside samples. The detection of identical DNA profiles in E. hirae isolates from inside and outside samples suggests the role of the air in bacterial dissemination from the inside of the broiler farm to the immediate environment.
