Presence of Rickettsia conorii subsp. israelensis, the Causative Agent of Israeli Spotted Fever, in Sicily, Italy, Ascertained Giovanni M. Giammanco,1 Giustina Vitale,2 Serafino Mansueto,2 Giuseppina Capra,1 Dipartimento di Igiene e Microbiologia1 and Dipartimento di Medicina Clinica e delle Patologie Emergenti,2 Received 31 May 2005/Returned for modification 17 July 2005/Accepted 17 September 2005 A retrospective analysis by molecular-sequence-based techniques was performed to correctly identify the
etiological agent of 24 Mediterranean spotted fever cases occurring in Western Sicily, Italy, from 1987 to 2001.
Restriction analysis of a 632-bp PCR-amplified portion of the ompA
gene allowed presumptive identification of
five clinical isolates as belonging to Rickettsia conorii
subsp. israelensis, the etiological agent of Israeli spotted
fever (ISF). The remaining 19 rickettsial isolates were Rickettsia conorii
subsp. conorii, the only pathogenic
rickettsia of the spotted fever group reported in Italy until the present. Sequence analysis of the ompA
confirmed the identification of all the R. conorii
subsp. israelensis isolates and demonstrated that rickettsiosis
caused by R. conorii
subsp. israelensis can be traced back to 1991 in Sicily. The recorded clinical data of the five
ISF patients support the idea that these strains could correlate to more-severe forms of human disease. Three
of five patients experienced severe disease, and one of them died.

Rickettsia conorii is thought to be the only pathogenic but more recently it has also been isolated in Portugal (3).

E-mail: for MSF in Palermo, Sicily, Italy, in the years 1987 to 2001. Heavily infected Vero cell monolayers were harvested and stored at Ϫ80°C until use. R. conorii subsp.
conorii type strain Malish (ATCC VR-613) was kindly provided by D. H. Walker TABLE 1. Rickettsial isolates collected in Sicily from blood samples of patients hospitalized for MSF during PCR amplification. Bacterial DNA was obtained from 200 ␮l of infected Vero
cell suspensions by using the Wizard Plus SV Minipreps DNA PurificationSystem (Promega, Madison, WI) according to the manufacturer’s instructions.
PCR was performed with the primer pair Rr 190.70p–190.701, which amplifies 632-bp portions of the ompA gene, under conditions described previously (18).
Two microliters of the DNA preparation was amplified in a 100-␮l reaction mixture containing 10 pmol each primer; 200 ␮M (each) dATP, dCTP, dGTP and dTTP (Amersham Pharmacia Biotech, Uppsala, Sweden), 1.25 U AmpliTaq Gold DNA polymerase (Applied Biosystems, Foster City, CA), and 6 ␮l of a 25 mM solution of MgCl2. Amplifications were carried out in a DNA thermal cycler (GeneAmp PCR System 2400; Perkin-Elmer, Applied Biosystems Division, Nor- R. conorii subsp. israelensis
walk, CT) under the following conditions. An initial 3 min of denaturation at 95°C was followed by 35 cycles of denaturation for 20 s at 95°C, annealing for 30 s at 46°C, and extension for 1 min at 65°C. The amplification was completed by holding for 7 min at 72°C. PCR products were purified as previously described by Restriction analysis. Amplified products were submitted to restriction analysis
with endonucleases PstI and RsaI (Amersham Pharmacia Biotech) as previously described (18). Restriction fragments were resolved on 10% polyacrylamide gels, and electrophoresis was performed in 1ϫ TBE buffer, pH 8 (44.5 mM Tris, 44.5 mM boric acid, 1 mM EDTA), at 120 V for 3 h. Gels were stained with ethidium bromide and examined with a UV transilluminator. HaeIII-digested pUC18 R. conorii subsp. israelensis
double-stranded DNA (Sigma-Aldrich, St. Louis, MO) was used as a molecular weight marker to calculate the sizes of the restriction fragments.
Sequence analysis. To confirm the presumptive identification obtained by
R. conorii subsp. israelensis
restriction analysis, PCR products of the Israeli spotted fever rickettsia isolates R. conorii subsp. israelensis
were sequenced in both the sense and antisense orientations (MWG-Biotech, R. conorii subsp. israelensis
Germany), and forward and reverse sequence data of each sample were aligned using the Bioedit program to obtain the final sequence. The DNA sequencesobtained in this study were analyzed using the BLAST program, availablethrough the National Center for Biotechnology Information (NCBI, Bethesda,MD; (1). The phylogenetic relationshipbetween our sequences and those of other rickettsiae of the SFG, retrieved from in 1995, 2000 (two), and 2001.
