Abstract
Aim: To determine the serum biochemical changes in Japanese quail (Coturnix coturnix japonica) experimentally infected with Salmonella enterica serovar Gallinarum Methods: A total of 160 (108 males and 52 females) Japanese quails (Coturnix coturnix japonica) were used for the experiment. Four weeks old quails were randomly selected and assigned into four groups (A, B,C and D) of forty quails each. Groups A, B and C were infected with Salmonella enterica serovar Gallinarum per os at the dose of 106,104and102, respectively, while group D served as the control. Sera were used for the determination of biochemical parameters. Results: There were significant changes (P<0.05) in serum glucose,total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and urea concentrations between infected groups and the control group.Significant changes (P<0.05) in these biochemical parameters were also observed post-infection compared to pre-infection within each infected group. Conclusion: FT in quails results in severe multi organ dysfunction and damage as demonstrated by the serum biochemical changes noticed suggestive of immediate cause of mortality in FT infection.

Highlights
The genus Salmonella is a member of the Family Enterobacteriaceae and consists of Gram-negative, non-spore forming bacilli (Popoff et al, 2003)
Quails are hardy birds which thrive very well in cages and are relatively inexpensive to maintain. They are birds that every household can keep without stress(Huss et al, 2008).The Japanese quail has the potential to complement the obvious gap in the protein needs of Nigerians, it is important to investigate diseases that can interfere with quail production such as fowl typhoid (FT) in order to control them(NVRI, 2008)
This study presents for the first time to the best of our knowledge that FT in quails results in severe multi organ dysfunction and damage which could be suggestive of immediate cause of mortality in FT infection
Summary
The genus Salmonella is a member of the Family Enterobacteriaceae and consists of Gram-negative, non-spore forming bacilli (Popoff et al, 2003). JAPANESE QUAIL research, because of their small size and require little cage space for rearing. They are easy to raise and are suitable for genetic studies since they attain sexual maturity rapidly (Haruna et al, 1997). Quails are hardy birds which thrive very well in cages and are relatively inexpensive to maintain They are birds that every household can keep without stress(Huss et al, 2008).The Japanese quail has the potential to complement the obvious gap in the protein needs of Nigerians, it is important to investigate diseases that can interfere with quail production such as FT in order to control them(NVRI, 2008). This study seeks to determine if any, the serum-biochemical changes in Japanese quail (Coturnix coturnix japonica) experimentally infected with Salmonella enterica serovar Gallinarum (Salmonella Gallinarum) reared in Zaria, Northern Nigeria
