The forelimb fetlock joint and its bony components are a common site of injury in racing horses. We hypothesized that the variations in relative density of these bones might correspond to their mechanical properties. This study aimed first to identify the relative density of third metacarpal bone (Mc3), proximal phalanx (P1) and proximal sesamoid bones (PSBs) of Thoroughbred race horses. Second, to determine whether there was any difference and/or similarity in the relative density between and within the bones. Bones from right and left forelimbs of 10 horses were collected and prepared by boiling and drying. Dry weight and volume for each bone were measured and the relative density was then calculated. Relative density of Mc3 was substantially greater than the other two bones with a mean of 1.7 ± 0.06. Relative density of P1 and PSBs showed a high similarity especially between P1 and the medial PSBs. Neither the comparisons between right and left sides nor between lateral and medial PSBs showed any significant differences. P1 had the most consistent relative density within right and left sides. Larger relative density in Mc3 and the similarity between P1 and PSBs presume a more important role of the bone mass on their properties than the volume.

Background and Aim: Foodborne illnesses are a serious challenge to human health and the economic sector. For example, salmonellosis remains a burden in developed and developing nations. Rapid and reliable molecular methods to identify Salmonella strains are essential for minimizing human infection. This study aimed to identify Salmonella spp. in raw milk and dairy products using conventional and molecular techniques and to test the antibiotic susceptibility of the isolated strains. Materials and Methods: One hundred and thirty-one milk and dairy product samples were randomly collected from different localities in Libya. Samples were examined for the presence of Salmonella by conventional culture techniques, including cultivation in Rappaport-Vassiliadis broth and streaking on xylose lysine deoxycholate agar. Identification also used polymerase chain reaction and partial sequencing of 16S rDNA. Twenty-four antibiotics were used for the examination of antimicrobial resistance of Salmonella spp. isolates with the agar disk diffusion method (Kirby–Bauer technique). Multi-antibiotic resistance index and antibiotic resistance index (ARI)for Salmonella enterica isolates were calculated. Results: Twenty-one of 131 samples (16%) were positive for Salmonella spp. recovered from 9 (16%), 2 (11%), 4 (22.2%), and 6 (46%) samples of raw cow milk, fermented raw milk, and fresh locally made soft cheeses, Maasora and Ricotta), respectively. Samples of ice cream, milk powder, and infant formula showed no Salmonella spp. contamination. Only 9 of 21 (42.8%) isolates were confirmed as S. enterica by partial sequence 16S rDNA analysis. All isolates were resistant to amoxycillin, bacitracin, penicillin G, lincomycin, vancomycin, clindamycin,
