Historically, neurocysticercosis (NCC) caused by the larval stage, cysticercus or cysticerci, of the pork tapeworm Taenia solium was recognized in Paniai District, western Irian Jaya Province, Indonesia, in the early 1970s. In the 1990s, we observed a rapid increase in the number of cases of epileptic seizures and burns in Assologaima Sub-District, Jayawijaya District, eastern Irian Jaya. There were totals of 1120 new cases of burns and 293 new cases of epileptic seizures during 1991-95 in Assologaima where the number of inhabitants was 15,939. Histopathological examination of resected cysts from patients and a pig revealed that they were cysticerci of T. solium. DNA analysis of these cysts revealed that the nucleotide sequences of 391 base-pair fragments of the mitochondrial cytochrome c oxidase subunit 1 gene were exactly the same in those from patients and the pig. Although 3 of 391 base-pair fragments might differ from that of T. solium reported previously, there were no differences in the amino-acid sequences. Approximately 67% and 65% of persons with epileptic seizures and with subcutaneous nodules, respectively, showed antibody responses highly specific to cysticercosis. Therefore, most cases of epileptic seizures and burns were considered to be associated with cysticercosis in Irian Jaya.

We studied evidence of Bartonella henselae andBartonella clarridgeiae infection in 54 cats living in Jakarta, Indonesia. By using an indirect immunofluorescence assay, we found immunoglobulin G antibody to B. henselae in 40 of 74 cats (54%). The blood of 14 feral cats was cultured on rabbit blood agar plates for 28 days. Bartonella-like colonies were identified as B. henselae or B. clarridgeiae by using restriction fragment length polymorphism analysis and direct sequencing of the PCR amplicons. Of the cats sampled in the study, 6 of 14 (43%; all feral) were culture positive for B. henselae; 3 of 14 (21%; 2 feral and 1 pet) culture positive for B. clarridgeiae. This is the first report that documents B. henselae andB. clarridgeiae infections in Indonesian cats.
