In Yersinia-PCR-positive patients, the serology was positive in 70% <strong>of</strong> the cases; the<br />

LTT in 50% [248].<br />

In the initial detection <strong>of</strong> Yersinia enterocolitica using culture methods, IgA <strong>and</strong> IgG<br />

b<strong>and</strong>s were found in immunoblot assay in patents experiencing a <strong>chronic</strong> course.<br />

The continuous detection <strong>of</strong> IgA antibodies was obviously an expression <strong>of</strong> a<br />

persistent infection; in this context the pathogens were detected in the intestinal<br />

mucosa <strong>and</strong> in lymphatic tissue. Hence, this was a definitely <strong>chronic</strong>, persistent<br />

Yersinia enterocolitica infection [258]. The antibiotic treatment <strong>of</strong> the Yersinia<br />

enterocolitica infection is presented in Table 18.<br />

Table 18<br />

Antibiotic treatment <strong>of</strong> the Yersinia enterocolitica infection<br />

Antibiotic Dose / Day<br />

Ceftriaxone 2 g<br />

+ Gentamycin 240 mg<br />

Cipr<strong>of</strong>loxacin 1000 mg<br />

Trimethoprim <strong>and</strong> sulfamethoxazole 875 / 125<br />

2 x daily<br />

In accordance with test:<br />

Gentamycin 240 mg<br />

Doxycycline 400 mg<br />

Piperacillin 8 g<br />

Invanz 1 g<br />

Yersiniosis frequently abates within a few weeks <strong>so</strong> that an antibiotic treatment is not<br />

generally recommended. This al<strong>so</strong> applies with regard to the excretors. Only in<br />

cases <strong>of</strong> severe <strong>disease</strong> courses, in particular with sepsis, are antibiotics used.<br />

Y. enterocolitica produces beta-lactamases with the consequence that penicillin,<br />

ampicillin <strong>and</strong> the cephalosporins <strong>of</strong> the first generation are ineffective [201, 205].<br />

There is al<strong>so</strong> frequently a resistance to macrolides.<br />
