2018
This study was conducted to investigate the beneficial effects of chitosan in the immunopathology of osteomyelitis in diabetic rabbits; therefore, the experimental design was carried out on 40 rabbits. They were divided into 5 groups each of 8 animals, diabetes mellitus was induced in rabbits , then infected by Staphylococcus aureus and treated as following: First group (G1) was induced diabetes mellitus then immunized by whole sonicated S. aureus antigens (WSSAG) and induced experimentally osteomyelitis. The second group (G2) was induced diabetes mellitus, then immunized by (WSSAG) and induced experimentally osteomyelitis and fed on diet containing chitosan. Third group (G3) was induced diabetes mellitus, and induced experimentally osteomyelitis only. Fourth group (G4) was induction of diabetes mellitus, and induced experimentally osteomyelitis and fed on diet containing chitosan. Fifth group (G5) was induced experimentally osteomyelitis only without diabetes mellitus induction. Then at day 28th - 30th post immunization, skin test was performed to each of the immunized groups, and at day 30th the antibodies titer was measured by passive hemagglutination assay and phagocytic activity, then the animals were sacrificed and the treated bone taken for histopathological examination. In the present study , a significant increase was noted in the value of skin thickness of G2 at 48 and 72 hrs PI. A significant increase was also noted in the value of antibodies titers of G2. We also showed a marked decrease in the t1/2 of carbon clearance of G2. The histopathological results of G2 showed normal periosteal surface and compact bone with active osteoblasts lining the trabecular bones 30 days PI. However, other groups showed many histopathological lesions like infiltration of inflammatory cells and proliferation of fibrous connective tissue in G1, G3, and G4.The results also showed necrotic bone, hemorrhage, inflammatory cells infiltration and fibrosis in G5. Taken together, these findings indicate that the chitosan had a beneficial effect in bone healing of diabetic animals after infection in S. aureus.

An identified local virulent Egyptian strain of turkey pox virus (TPV) was attenuated on specific pathogen free (SPF) embryonated chicken eggs (ECE) for production of specific turkey pox vaccine. Forty serial passages of the virus were applied on the chorioallantoic membrane (CAM) of SPF ECE, so titration of the serial passages were undergone in which the highest titres (107.0, 107.1 and 107.1 EID50/ml) were recorded for the passages 30, 35 and 40, respectively. The pathogenicity of the 10th, 20th, 30th and 40th passages were tested by inoculation in susceptible turkeys. The passage of 30th and 40th passages produced the most acceptable post vaccinal reaction (pvr) beside giving the highest virus titre of the attenuated passages. The selected field dose which gave only takes (swelling of the skin) at the site of injection in susceptible turkeys and withstood challenge with the virulent turkey pox virus one month later was 104.0 EID50/ml. The prepared vaccine tested for sterility, safety and potency tests and proved to be potent for the vaccinated turkeys which resisted the challenge for 9 months post vaccination. Antibody levels in the serum of vaccinated turkeys were estimated by serum neutralization test, where neutralizing antibodies expressed as neutralizing index were appeared from the 1st week (1.0 NI) and reached its peak on the 3rd week (2.2 NI) post vaccination

Nanoparticles have many characteristics that make them suitable for biological and medical applications. Uptake of thesenano particulates into animals and humans bodiesthrough different routes may exhibit potential side effects. Titanium dioxide (TiO2) is a common additivethat is increasingly used in consumer products, food,pharmaceutical dosage forms and cosmetic articles. In this study, the effects of oral administration of TiO2 nanoparticles (500 mg| kg .bw) for 60 days were investigated on kidney function and histopathological changes. The body weight gain and kidney/body weight ratio showed no significant changes in comparison with control group. There was a significant decrease in total thiol levels in kidney homogenate, the biochemical changes was supported by histopathologicalultration. In conclusion the data shows that the oral administration of TiO2 NPs may lead to renal toxicity in experimental rats.

This work was planned to investigate the prevalence of antimicrobial resistance of Enterococcus faecalis isolated from animal and human sources. Ten isolates of E. faecalis recovered from urinary tract infections in humans, as well as, ten isolates of E. faecalis were recovered from diarrheic dairy cattle studied for their antimicrobial sensitivity to 7 different antibacterial agents. Antimicrobial sensitivity pattern proved that most isolates were resistant to most of the tested antimicrobial agents. All isolates of human E. faecalis were 100 % resistant to rifamycin, gentamicin and penicillin G. Resistance to amikacin, ciprofloxacin, levofloxacin and vancomycin was 80.0%, 90.0%, 90.0% and 70.0% respectively. However animal E. faecalis were completely (100%) resistant to penicillin G and ciprofloxacin. Resistance to gentamicin, amikacin, levofloxacin, rifamycin and vancomycin was 70.0%, 40.0%, 20.0%, 20.0% and 0.0% respectively. PCR was applied on MDR for detection of aminoglycosides resistance genes. All human E. faecalis isolates were negative for aph(2‖)-Ia, aph(2‖)-Ib, aph(2‖)-Ic and aph(2‖)-Id. 40.0% of isolates were proved to harbour aph(3‖)-IIIa and 10.0% (one isolate) harboured ant(4‖)-Ia. However all animal E. faecalis isolates were negative for aph (2‖)-Ib, aph(2‖)-Ic, aph(2‖)-Id. Two isolates (20.0%) harboured aph(2‖)-Ia and ant(4‖)-Ia and four isolates (40.0%) harboured aph(3‖)-IIIa. In conclusion, the increased antibiotic resistance of E. faecalis isolated from animal and human sources complicate treatment decisions and increase public health hazard.
