A pаtient is suspected оf hаving а Shigella sоnnei infectiоn.  At the onset of infection, a blood sample is taken.  Six weeks later, a second, convalescent sample is taken and serum from each is titered using an agglutination technique in which antigens unique to Shigella sonnei are adsorbed onto treated red blood cells.  Results are depicted below.  Row 1 is the positive control and Row 6 is the negative control.  The patient’s convalescent serum is in Row 3 and the sample taken at the onset of infection is in Row 4.  What is the most likely diagnosis?
