The present study determined the genetic relationships between 41 Staphyloccocus (S.) aureus isolates from bovines, humans, and food using a single enzyme amplified fragment length polymorphism (AFLP) technique. We evaluated the prevalence of staphylococcal enterotoxin (SE) genes and other virulence gene determinants by PCR. The identification of S. aureus was based on culturing and biochemical tests, and by amplifying a specific section of the 23S rRNA gene. PCR amplification of the SE genes (sea, seb, sec, see, seg, seh, and sei) singly or in combination was observed. Most isolates of bovine origin harbored hla (84%) and cap5 (74%), while most isolates from humans harbored hla (73%), cap8 (91%), and fnbA (100%). Strains from food sources were positive for hla (100%), cap5 (100%), and cap8 (64%) unlike isolates from humans or bovines. A single enzyme AFLP analysis revealed a correlation between AFLP clusters of some strains and the source of the isolates The genotypic results of the present study might help to better understand the distribution of prevalent S. aureus clones among humans, bovines, and food and will help control S. aureus infections in Indonesia.

In the present study, 35 Staphylococcal strain isolated from milk samples of 16 cows from eight farms of three different geographic locations in Central Java, Indonesia, and from milk samples of 19 cows from 19 farms of different geographic locations in Hesse, Germany, were compared pheno- and genotypically. On the basis of cultural and biochemical properties as well as by amplification of the 23S rRNA specific to Staphylococcus aureus, all isolates could be identified as S. aureus. In addition, all S. aureus isolates harboured the genes clfA and coa encoding staphylococcal clumping factor and coagulase, and the gene segments encoding the immunoglobulin G binding region and the X-region of protein A gene spa. By PCR amplification, the genes seb, seg, seh, and sei was observed for the S. aureus cultures isolated in Central Java, Indonesia and the genes sec, sed, seg, seh, sei, sej and tst for the S. aureus cultures isolated in Hesse, Germany. None of the S. aureus of both origins harboured the genes sea, see, eta and etb. All isolates were additionally positive for the genes nuc, fnbA, hla, and set1. The gene hlb was found for 6 cultures from Central Java, Indonesia and 16 cultures from Hesse, Germany. However, the gene fnbB and the gene segments cnaA and cnaB were not present among the strains isolated in Central Java, Indonesia and rare among the strains isolated in Hesse, Germany. It was of interest that most of the S. aureus isolated in Central Java, Indonesia harboured the gene cap5 and most of the strains isolated in Hesse, Germany the gene cap8. The phenotypic and genotypic results of the present study might help to understand the distribution of prevalent S. aureus clones among bovine mastitis isolates of both countries and might help to control S. aureus infections in dairy herds.

In the present study 41 mucoid growing Streptococcus equi subsp. zooepidemicus strains (37 strains isolated from healthy two from diseased pigs, two strains isolated from healthy monkeys) appeared to be phenotypically and genotypically identical to mucoid growing S. equi subsp. zooepidemicus strains isolated from a previously described outbreak among the pig and monkey population on the island of Bali, Indonesia. These findings indicate that the mucoid growing S. equi subsp. zooepidemicus clone was still present in the pig and monkey population in Indonesia.

Background: Chlamydophila felis, formerly known as Chlamydia psittaci var. felis, is frequently associated with ocular, respiratory, and occasionally reproduction tract infections. Even though the infection is sometimes asymptomatic, it potentially results in a latent immunosuppressive infection. Objective: This study aimed to identify occurrences of feline chlamydophilosis, rarely reported in cats in Indonesia. Methods: The observation was conducted in three cats with clinical signs of Cp. felis infection, particularly relapsing conjunctivitis. The cats' histories were recorded based on owners' information. Conjunctival swabs were sampled for cytology examination and molecular assay detection. A phylogenetic tree was generated using MEGA-X software to reveal group clustering. A post-mortem examination was performed on the cat that died during an examination. Results: Cp. felis was detected in both cytological examination and polymerase chain reaction assay. The phylogenetic tree demonstrated that the Cp. felis isolated in this study clustered with several other isolates from the other countries. Cp. felis can be isolated from cats with different clinical manifestations and levels of severity. The chronic fatal infection demonstrated interstitial broncho-pneumonia under histopathological examination. Conclusions: Molecular assay of Cp. felis is always recommended to obtain a definitive diagnosis of feline chlamydophilosis since the disease can have various clinical manifestations. Even though it may be subclinical and is often not fatal, an infected cat may be a carrier that could spread the pathogen in the surrounding environment. Serious disease management is suggested to avoid high costs associated with regularly relapsing disease.
