Salmonella sp. and Shigella sp.in House Flies in Jatinangor

Background: Diarrhea is a common problem in Indonesia and mostly caused by pathogenic bacteria such as Salmonella sp. and Shigella sp., transmitted by house flies. The incidence of acute diarrhea has been rising over the years. The aim of this study is to determine if Salmonella sp. and Shigella sp. can be found in house flies in Jatinangor.Methods: A descriptive study was done, involving 20 samples of house flies caught from houses and street vendors in Jatinangor during the period of March 2012 to January 2013. Bacteria were isolated from house flies and identified using various biochemical tests.Results: Shigella sp. was isolated from 5% of the house flies caught in Jatinangor. The house flies caught from the street vendors revealed a higher percentage of bacteria than those caught from houses.Conclusion: Only Shigella sp. can be isolated from house flies in Jatinangor. However, a small percentage of Shigella sp. was also found from the house flies captured around Jatinangor.

Nasopharyngeal bacterial carriage and antimicrobial resistance in underfive children with community acquired pneumonia

Lung puncture is the best way to determine the etiology of pneumonia since it yields the highest rate of positive cultures. However, this procedure is difficult, especially for a study in the community. According to WHO, isolates to be tested for antimicrobial resistance in the community should be obtained from nasopharyngeal (NP) swabs. Previous studies support the use of NP isolates to determine antimicrobial resistance patterns of isolates from children with pneumonia. The aim of our study was to know the bacterial patterns of the nasopharynx in underfive children with community acquired pneumonia and their antimicrobial resistance. The study was carried out in 4 Primary Health Clinics in Majalaya sub-district, Bandung, Indonesia. All underfives with cough or difficult breathing and classified as having non-severe pneumonia (WHO guidelines), were included in the study. Nasopharyngeal swabs (CDC/WHO Manual) were obtained by the doctor, the swabs were placed in Amies transport medium and stored in a sterile jar before taken to the laboratory in the same day. All children were treated with co-trimoxazole. During the nine month study, 698 children with clinical signs of non-severe pneumonia were enrolled. About 25% of the nasopharyngeal specimens yielded bacterial isolates; the two most frequently found were S. pneumoniae and S. epidermidis. The antimicrobial resistance test to co-trimoxazole showed 48.2% S. pneumoniae strain had full resistance and 32.7% showed intermediate resistance to co-trimoxazole. This result is almost similar to other studies from Asian countries. It seems that H. influenzae is not a problem in the study area; however, further studies are needed

Risk factors associated with nasopharyngeal carriage and density of Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus in young children living in Indonesia

Abstract Background Potentially pathogenic bacteria Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus are commonly carried in the nasopharynx of young children. Host and environmental factors have been linked with pathogen carriage, and in many studies rural children have higher carriage rates than their urban counterparts. There are few published data on what factors contribute to increased pathogen density. The objectives of this study were to identify risk factors for nasopharyngeal carriage and density of S. pneumoniae, H. influenzae, M. catarrhalis, and S. aureus in young children in Indonesia. Methods Risk factor analysis was done using data on bacterial carriage and participant characteristics from a cross-sectional study that enrolled 302 children aged 12–24 months living in urban or semi-rural areas of Indonesia. Associations between host factors and odds of pathogen carriage were explored using logistic regression. Characteristics identified to be independent predictors of carriage by univariable analysis, as well as those that differed between urban and semi-rural participants, were included in multivariable models. Risk factors for increased pathogen density were identified using linear regression analysis. Results No differences in carriage prevalence between urban and semi-rural children were observed. Multiple children under the age of 5 years in the household (< 5y) and upper respiratory tract infection (URTI) symptoms were associated with S. pneumoniae carriage, with adjusted odds ratios (aOR) of 2.17 (95% CI 1.13, 4.12) and 2.28 (95% CI 1.15, 4.50), respectively. There was some evidence that URTI symptoms (aOR 1.94 [95% CI 1.00, 3.75]) were associated with carriage of M. catarrhalis. Children with URTI symptoms (p = 0.002), and low parental income (p = 0.011) had higher S. pneumoniae density, whereas older age was associated with lower S. pneumoniae density (p = 0.009). URTI symptoms were also associated with higher M. catarrahlis density (p = 0.035). Low maternal education (p = 0.039) and multiple children < 5y (p = 0.021) were positively associated with H. influenzae density, and semi-rural residence was associated with higher S. aureus density (p < 0.001). Conclusions This study provides a detailed assessment of risk factors associated with carriage of clinically-relevant bacteria in Indonesian children, and new data on host factors associated with pathogen density
