“…Similarly, it was reported that the arteria axillaris was a branch of the arteria subclavia on the left side of the body in the long-legged buzzard (Erdogan ve Kilinc, 2014). Likewise, it was stated that the arteria axillaris was a branch ramifying independently from the arteria subclavia in Eurasian bittern (Erdogan, 2012) and it was always a separate vessel in the Whooping Crane (Fisher, 1955). In accordance with these reports, examined in this study, the arteria axillaris was also ramifying from the arteria subclavia as sepa- rate vessel in the sparrowhawk ( Fig.…”

ABSTRACT. This study was aimed to determine the vascular arrangement of the wing arteries in the sparrowhawk. For this purpose, wing arteries of eight sparrowhawks were assessed by latex injection method and angiography. Latex injection method was applying to the five materials and barium sulphate solution was injected for angiography in other three materials. It was observed that the arterial blood was mainly provided to the wing by arteria axillaris. The arteria axillaris gave off arteria subscapularis. After branching the arteria subscapularis, it emitted the arteria profunda brachii and arteria supracoracoidea. After ramifying these vessel, the arteria axillaris continued down arteria brachialis. This vessel was giving off the arteria circumflexa humeri from its cranial aspect. In the nearby the cubital fossa the arteria brachialis bifurcated arteria ulnaris and arteria radialis. The arteria ulnaris gave off common stem of arteria recurrens ulnaris et arteria ulnaris profunda. After branching the common stem, the arteria ulnaris proceeded as arteria ulnaris superficialis. The arteria radialis was the deep terminate branch of the arteria brachialis. This vessel bifurcated the arteria radialis profunda and arteria radialis superficialis.

“…The term ‘aortic vessels' in our paper corresponds to the aortic arch and the brachiocephalic trunk. By contrast to mammals, two brachiocephalic trunks arise from the arch of the aorta and give rise to the common carotid and subclavian arteries in birds [ 62 ]. For this organ, only 55% of the cells were identified through flow cytometric analysis.…”

Poultry are the main source of human infection by Salmonella . As infected poultry are asymptomatic, identifying infected poultry farms is difficult, thus controlling animal infections is of primary importance. As cell tropism is known to govern disease, our aim was therefore to identify infected host–cell types in the organs of chicks known to be involved in Salmonella infection and investigate the role of the three known invasion factors in this process (T3SS-1, Rck and PagN). Chicks were inoculated with wild-type or isogenic fluorescent Salmonella Typhimurium mutants via the intracoelomic route. Our results show that liver, spleen, gall bladder and aortic vessels could be foci of infection, and that phagocytic and non-phagocytic cells, including immune, epithelial and endothelial cells, are invaded in vivo in each organ. Moreover, a mutant defective for the T3SS-1, Rck and PagN remained able to colonize organs like the wild-type strain and invaded non-phagocytic cells in each organ studied. As the infection of the gall bladder had not previously been described in chicks, invasion of gall bladder cells was confirmed by immunohistochemistry and infection was shown to last several weeks after inoculation. Altogether, for the first time these findings provide insights into cell tropism of Salmonella in relevant organs involved in Salmonella infection in chicks and also demonstrate that the known invasion factors are not required for entry into these cell types.

“…The term “aortic vessels” in our paper corresponds in fact to the aortic arch and the brachiocephalic trunk. In contrast to mammals, two brachiocephalic trunks arise from the arch of the aorta and give rise to the common carotid and subclavian arteries in birds (54). This “organ” was chosen as a source of endothelial cells.…”

Salmonella are among the most important foodborne pathogens and contaminated poultry meat and eggs are the main source of human infection. Infected poultry are a major problem as they are asymptomatic, thus rendering the identification of infected poultry farms difficult. In this context, controlling animal infections is of primary importance. It is known that cell and tissue tropism govern disease in many infectious models, our aim was therefore to identify the infected host-cell types in chicks and the role of the three known bacterial invasion factors in this process (T3SS-1, Rck and PagN). Chicks were inoculated with wild-type or isogenic fluorescent Salmonella Typhimurium mutant strains via the intraperitoneal route. Then infected cells in the liver, spleen, gall bladder and aortic vessels were identified using flow-cytometric analyses and invasion confirmed by confocal microscopy. Our results show that all these organs could be foci of infection and that a wide array of phagocytic and non-phagocytic cells is invaded in vivo in each organ. These cells include immune cells and also epithelial and endothelial cells. Moreover, we demonstrated that, despite the invalidation of the three known invasion factors (T3SS-1, Rck and PagN), S. Typhimurium remained able to colonize internal organs and invade non-phagocytic cells in each organ studied. In line with this result, the mutant strains colonized these organs more efficiently than the wild-type strain. S. Typhimurium invasion of gall bladder cells was confirmed by immunohistochemistry and infection was shown to last several weeks after inoculation of chicks and at a level similar to that observed in the spleen. All together, these findings provide new insights into the dynamics of Salmonella spread in vivo in chicks at the organ and cellular levels.Author summaryIn many infectious models, cell and tissue tropism govern disease. Moreover, depending on the entry process, both bacterial behavior and host response are different. It is therefore important to identify the host cells targeted in vivo by a pathogen and the entry routes used by this pathogen to invade the different host cells. This is all the more important with a pathogen that enters cells in several ways like Salmonella, which is responsible for human and animal salmonellosis. As poultry meat and eggs are the main sources of human contamination, controlling animal infections is of primary importance. In this paper, we identified a large array of phagocytic and non-phagocytic cells targeted in vivo using fluorescent Salmonella Typhimurium strains inoculated by the intraperitoneal route. Surprisingly, the same host cells were infected by the wild-type strain or its isogenic mutants deleted of either the T3SS-1 or of the three known invasion factors (T3SS-1, Rck and PagN). These cells were immune cells but also epithelial and endothelial cells. Moreover, we demonstrated for the first time that the gall bladder and the aortic vessels could be foci of infection in chicks in addition to the liver and spleen.
