The purpose of this study was to examine the mechanical adaptations linked to economical locomotion in cursorial bipeds. We addressed this question by comparing mass-matched humans and avian bipeds (ostriches), which exhibit marked differences in limb structure and running economy. We hypothesized that the nearly 50 per cent lower energy cost of running in ostriches is a result of: (i) lower li...

The aim of this study was to determine for reference purposes the values of serum albumin, alpha 1-globulin, alpha 2-globulin, beta-globulin, gamma-globulin, and alpha-lipoprotein (high density lipoprotein), pre-beta-lipoprotein (very low density lipoprotein) and beta-lipoprotein (low density lipoprotein) fractions of normal ostriches (Struthio camelus) in Turkey. Five male and five female ostr...

Biochemical and qualitative evaluation of the supernatant of urine from hydrated farmed ostriches (Struthio camelus) indicated that the urine was comparable to that described by other workers. The disparities obtained between the biochemical constituents in the present and previous studies were partly attributed to the state of hydration influenced by climatic factors. Results of the cytologica...

Crocodiles and ostriches are very sensitive to stress, and the ideal conditions for intensive rearing have not yet been established. Consequently, mortality is often directly linked to conditions on the farm. Crocodile and caiman pox, adenoviral hepatitis, mycoplasmosis, chlamydiosis and coccidiosis are crocodile-specific infections with reservoirs in wild populations and adult wild-caught bree...

BACKGROUND The parasites Toxoplasma gondii (T. gondii) and Neospora caninum (N. caninum) are globally distributed; they infect warm-blooded animals, including many avian species. The aim of this study was to evaluate the presence of these parasites in ostriches from central China. In total, 402 ostrich (Struthio camelus) samples (293 hearts, 77 brains, and 32 serum) from slaughterhouses of the ...

We studied the strategies used by cursorial bipeds (ostriches) to maneuver during running. Eight ostriches were induced to run along a trackway and execute turns. Ground reaction forces and three-dimensional kinematics of the body and leg joints were simultaneously recorded, allowing calculation of joint angles and quasi-static net joint torques. Sidesteps, where the leg on the outside of the t...

Ostriches are frequently infected with viral, fungal, and bacterial diseases. This disease does not require airborne transmission involve the respiratory system. Objective: To determine antimicrobial activity of Moringa oleifera tea leaves seed against bacteria in Ostrich feces. Methods: Fecal samples were collected from captive ostriches at W.A Apparel factory. E. coli was isolated after inocu...

We developed a three-dimensional, biomechanical computer model of the 36 major pelvic limb muscle groups in an ostrich (Struthio camelus) to investigate muscle function in this, the largest of extant birds and model organism for many studies of locomotor mechanics, body size, anatomy and evolution. Combined with experimental data, we use this model to test two main hypotheses. We first query wh...

background mycoplasma synoviae is an important avian pathogen which can cause both respiratory disease and synovial joint inflammation (synovitis) in poultry. mycoplasmas spp. may cause the respiratory system infection in ostriches with symptoms such as inflammation of the nose, trachea and also damages of lungs. objectives the current study aimed to use the m. synoviae specific polymerase chai...
