This study compared the instrument performance and tissue healing of a steel scalpel with a CO₂ laser in an animal urinary bladder surgery model. Landrace and Yorkshire mixed breed pigs were used. Two symmetrical incisions were made in urinary bladder of each pig. One incision was made on the left side of ventral aspect on urinary bladder using a steel scalpel, while the other incision was performed on the right side using a CO₂ laser with an 8W output power. Each instrument was evaluated clinically for speed, ease of incision, and extent of bleeding. At 7 and 21 days after initial wounding, each wound was taken for histological observations. The scalpel was an easier instrument to use in the confines of the urinary bladder tissue, compared with the laser. However, there was no significant difference between the two groups. The amount of bleeding was less in the laser group but the time of the incisions was shorter with the scalpel. Scalpel incisions showed complete restoration of the epithelium and muscularis. On the other hand, the laser incisions showed incomplete restoration of the epithelium and muscularis. However, most of wound healing in the laser incisions was accomplished according to the time lapse. Although the scalpel produced less damage to the urinary bladder tissue and was easier to handle than the CO₂ laser, it did not provide hemostasis that was helpful for use on highly vascular tissue. The CO₂ laser provided good hemostasis, but delayed wound healing. In conclusion, the CO₂ laser provided better hemostasis and better surgical field than the scalpel. The CO₂ laser was used effectively in urinary bladder incision.

A 3-year-old female Thoroughbred racehorse was presented following the accidental oral and skin administration of amitraz. This case report describes the clinical signs and the treatment of this horse. Clinical signs of amitraz toxicosis are associated with the stimulation of alpha2-adrenergic receptors. Amitraz is seldom fatal because the effects can be reversed by alpha2-adrenergic antagonists. The horse displayed typical clinical signs of colic, including pawing, small hard drops, tranquillisation, depression, ataxia, muscular incoordination and impaction colic lasting up to 7 days. The syndrome was accompanied by mild dehydration. The horse survived after persistent symptomatic treatment, including the giving of intravenous fluids, antibiotics, multiple doses of mineral oil per os, nonsteroidal anti-inflammatory drugs and dexamethasone intramuscularly and intravenously.

Combination therapy of antibiotics is leading to improved efficacy or safety profiles with decrease emergence of bacterial resistance. Because of this benefit, many of antibacterial combinations have been used in veterinary practice for the past few decades. The purpose of this study was to examine the in vitro activity of an amoxicillin alone and in combination with other antibiotics against pathogenic bacteria of fish origin. Based on the fractional inhibitory concentration (FIC) index (FIC less-than or equal to 0.5), a synergistic interaction was shown in combination of florfenicol with amoxicillin or cefuroxime. The combination of florfenicol and amoxillin showed higher antibacterial activity than that of florfenicol and cefuroxime. Ratio of amoxicillin and florfenicol in combination was 1 : 1, which showed the antibacterial activity against bacterial isolates of fish as compared with other ratios. A synergetic effect of the combination (amoxicillin and florfenicol) was further confirmed in the time-kill curve study. The study showed a better in vitro antibacterial activity of a 1 : 1 combination of amoxicillin and florfenicol than the individual antibacterial against bacterial isolates of fish. In conclusion, the combination of florfenicol and amoxicillin may serve as a potential antibacterial therapy in fishes infected pathogenic bacteria.

Candidiasis is a mycosis caused by the mycelial yeast of the Candida genus which is opportunistic pathogen of humans, animals, and birds. Under some conditions such as prolonged antibiotic therapy, overcrowding, and immunosuppression, the opportunistic Candida can cause disease. Chicken candidiasis is sporadically occurred and characterized by unsatisfactory growth, listlessness, roughness of feathers, and death. A case of 23 weeks old layer with history of increased mortality and anemia was submitted to our Lab. At necropsy, the characteristic lesions were observed in the crop and proventriculus. The whitish pseudomembrane, that are peeled easily, was found in the crop. Proventriculus was swollen and the mucosa was covered with hemorrhagic exudate. The histological changes of the affected crop are epithelial hyperplasia, hydropic degeneration, and mycelia formation. Smears made from the necrotic mucosal surfaces of the crop revealed the presence of large number of yeast cells and mycelia. Pure cultures of yeast colonies were obtained from the potato dextrose agar. The yeast cells were identified as Candida albicans by gene sequencing. To our knowledge, this is the first report of candidiasis in chickens with anemia in Korea.

The present study concerned with Listeria monocytogenes which were isolated from apparently healthy buffaloes, buffaloes suffered from abortion, bedding and silage, which were collected from different localities. From the total examined samples (375), (300 samples from apparently healthy buffaloes, bedding and silage, also 75 samples from buffaloes suffered from abortion , bedding and silage) the prevalence of L. monocytogenes was 11(14.7%), isolates from buffaloes suffered from abortion, bedding and silage. All isolates were motile at room temperature, also exhibited positive CAMP test and exhibited narrow zone of β-hemolysis. Serological identification of isolates revealed 6(54.5%) were serotype 4 while 5(45.5%) were untyped. There were differences in isolates susceptibilities to different anti-microbial agents. L. monocytogenes had 100% sensitivity to Ampicillin, chloramphenicol, erythromycin, tetracycline and ceftiofur sodium. Virulence of isolates was assayed by I/P inoculation of 109 CFU in mice, all inoculated mice died within 1-5 days. PCR assay for L. monocytogenes isolates revealed positive amplification of 827 bp fragment of act A gene.

This study was carried out to evaluate the immunomodulating effects of, inactivated cells of Propionibacterium acnes and cell wall lipopolysaccharide (LPS) of the a pathogenic E. coli (INMUNAIR® 17.5) 0.5ml/ L and 1-3, 1-6 β-glucans (BETAPOLO®) 1 ml / L on the immune response of chickens to Newcastle disease (ND) vaccine. The results showed that administration of IMR before vaccination was resulted in food conversion rate (FCR) higher than after vaccination . Significantly higher NDV HI antibody titers in IMR and Betapolo medicated groups as compared with control groups which in turn induce high protection rate in challenge test .Thymus, spleen and bursal indices of control negative showed significantly lower values than vaccinated medicated and non- vaccinatedmedicated groups (P≤ 0.05).

The present study was designed to determine the effect of the antioxidants; taurine, ascorbic acid '' AA '' and beta-mercaptoethanol '' β-ME '' separately or in combination, on reproductive performance of adult male rats suffering from cadmium chloride "CdCl2" - induced oxidative stress. A total of 180 mature male Albino rats were equally divided into 9 groups; the rats of the 1st were administered distilled water while those of the 2nd group were administered 1/100 LD50 of CdCl2. Rats of the remaining groups were administered 1/100 LD50 of CdCl2 followed 3 days later by 1 / 50 LD50 of either taurine, AA and β-ME or a combination of AA and taurine, AA or β-ME, taurine and β-ME as well as AA, taurine and β-ME, respectively for 2 successive months. The results revealed that application of CdCl2 for 8 successive weeks decreased pituitary and serum levels of gonadotropins (gametogenic hormone”FSH” and interstitial cell stimulating hormone “ICSH”) as well as serum testosterone “T” level, altered semen quality, and decreased serum level of total antioxidant capacity with increased serum malondialdhyde "MDA" level. On the other side, application of different antioxidants to CdCl2 –induced oxidative stress increased pituitary and serum levels of gonadotropins and serum level of T as well as improved semen quality, increased serum level of total antioxidant capacity and decreased serum level of MDA. In addition, the best improvement in male reproductive performance was achieved after administration of AA and taurine separately or in combination while the least improvement was obtained when β-ME was applied alone.

A total of 90 one-day-old male broiler chicks were fed on balanced ration for 15 days and then divided into 3 equal groups. Control group fed ration probiotic free, group 2 and 3 fed ration supplemented with probiotic at concentration levels 0.5 and 1.0g/kg ration respectively for 4 weeks.It was found that probiotic improve body weight gain and feed conversion ratio. Relative organs weights were not altered in groups of birds fed ration mixed with probiotic. Serum values of biochemical parameter (AST, ALT, ALP, total protein, A/G ratio, Ph) were not significantly changed in comparison to control group. Probiotic enhance the immune response of broiler chickens in a dose dependent relation as documented by increasing the serumNDHI antibody geometric mean titres to ND vaccine, phagocyte percentage and phagocytic index of peripheral blood monocyte of broiler chickens. We concluded that probiotic composed of 3 strains of bacteria (Pediococcus acidilactici, Pediococaoccus pentosaceus and Bacillus Amylolique- faciens) in addition to 2 strains of yeast( Pichia farinose and Dekera anomala ) enhance body weight gain, feed conversion, growth performance and Newcastle disease antibody titres in broiler chickens. Moreover, probiotic was safe as proved by serum biochemical profile and relative organ weight of male broiler chickens.

Using plate methods, flavonoids extract of Cucurbita pepo had the highest effect and wide diameter of growth inhibition zones against serratia and Escherichia coli and it has no effect on growth of Bulkholderia pseudomallia

In this study a total of 928 Holstein cows daughters of 33 sires bred at Al-Naser Dairy Cow Station (60 km south of Baghdad) were used to appraisal the final score for the 14 linear type traits: rear udder height (RERUDHIH), teat length (TETLENGT), strength(STRENGTH), dairy form (DAIRYFOM), rump angle (RUMPANGL), body depth (BODYDEP), fore udder attachment (FORUDER), teat placement (TETPLACM), udder depth (UDERDEPT), udder suspension (UDERSUSP), rear udder width (RERUDWID), rear leg set (RLSET), foot angle (FOTANGLE) and rump width (RUMPWIDT). Heritability of type traits ranged from 0.080 to nearly one, and different methods did not exhibit high variability in heritability estimates for each trait. Age showed significant affect on BODYDEPT and TETPLACEM. Day in milk showed significant effect on TETLENGT, STRENGTH and UDDERDEPT. The genetic correlation among type traits ranged from -0.724 to 0.904. It was positive and high between milk yield and RERUDERWIDT, RUMPANGL and TETLENGT. However, milk yield negatively correlated with UDERDEPT and RLSET. The breeding values for sires in deferent traits ranged from -7.656 to 8.868, and showed a high variability among sires for each trait in this study
