Background: Several animal species may act as a possible reservoir for transmission of MRSA to human. The aim of this study was to determine the antibiotic resistance profiles of Staphylococci from animals.Methods: A total of 754 nasal and rectal swab samples collected from apparently healthy animals at Batna and Setif governorate, eastern Algeria. For this purpose, we studied the antimicrobial susceptibility of the isolates by conventional methods (Disk diffusion test and methicillin resistance by Cefoxitin disk diffusion test).Result: The overall prevalence of S. aureus isolates from 754 samples was 43.61%, with a high rate of S. aureus isolation in rabbits (92%). Goats, bovine, dogs, cats, horses, poultry presented a medium prevalence with 31.91%, 25%, 23.75% 21.25%,15% and 15% respectively, while the lowest rate was observed in sheep with 10%. MRSA were isolated in all animal species (29.46%). All detected isolates were multiple drug resistant (MDR). A complete resistance (100%) was noted for ciprofloxacin and gentamicin in sheep and horses and to penicillin in dogs. MRSA is a serious problem for human and animal health; therefore, several experiments must be carried out to demonstrate possible transmission of MRSA between companion or food-chain animals and humans, as well as some MRSA clones of human origin that have adapted to new animal hosts eventually by losing useless virulence factors or acquiring new mobile genetic elements.

Background: In recent years, several works have examined the reproductive traits of Algerian local population rabbit does but no standardization study has been done on the plasmatic parameters of this population of rabbits reared in the Aures region during their different physiological stages. Therefore, the present study evaluated the effect of these on certain blood parameters in local rabbit does.Methods: The rabbit does (n=120) were randomly divided into 4 treatment groups; Empty (E), Pregnant (P), Pregnant lactating (P-L) and Lactating (L). Does were first mated at the age of 16.5 weeks with an average body weight of 3107.1 ± 53.5g and with body condition scoring (BCS) of loin and rump ranging from 2 to 3 on a scale of 1- 5 following a 42-day rhythm. Four blood samples were collected from females of five rabbits in each group viz. E, P, P-L and L respectively.Result: Milk yield differs significantly (p less than 0.05) between the two experimental groups (P-L and L). Litter size and litter weight of does at birthing was higher (p less than 0.01) in L group than in P and P-L groups. That the mean levels glucose in non-pregnant group recorded as 0.22±0.04g/l which was increased 3rd week of pregnancy (0.65± 0.1 g/l followed by low mean value 0.35+0.2g/l and 0.4+0.1g/l at pregnant lactating and lactating stages of experimental rabbits. The lowest level of protein was recorded in the second week of pregnancy (p less than 0.05). The increase in total protein, albumin and globulin concentrations in lactating group might be physiological. Concerning total lipids, there was a strong mobilization of body fat in pregnant females (97 mg/dl ± 0.10; p less than 0.05). However, a marked decrease (p less than 0.05) was recorded in cholesterolemia in lactating females. Regarding triglyceridemia, we have recorded a significant raise (37.7 ± 35.6; p less than 0.001) in pregnant females. The creatinine value recorded was close to the physiological norms 1.3-2.7 mg/dl vs 1.08 -0. 92 mg/dl. T3 plasma levels were lower (p less than 0.05) in lactating females’ group. Pregnant and lactating does showed an increase (p less than 0.05) of leptin level. The higher (p less than 0.05) progesterone levels in pregnant and pregnant-lactating does than its concentrations in empty and lactating does might be attributed to maintaining pregnancy. Therefore, the current study confirms that the analysis of metabolites represents a good tool to understand the physiological mechanisms.
