Diagnosis of asymptomatic bacteriuria and associated risk factors among pregnant women in mangalore, karnataka, India.

BACKGROUND: Asymptomatic bacteriuria (AB) is common inwomen and increases in prevalence with age or sexual activity. Prompt detection and treatment of this condition and associated factors decreases complications like acute pyleonephritis, intrauterine growth retardation and preterm labour. Chromogenic media is a versatile tool in rapid primary screening of the causative organisms considerably reducing daily routine workload. AIM: To determine the prevalence of AB among pregnant women in a tertiary care set-up and analyse the contributory risk factors, its effects on pregnancy and the role of chromogenic media in the laboratory diagnosis of these cases. MATERIALS AND METHODS: Urine samples of all pregnant women attending pre-natal check-ups with no genitourinary complaints, history of fever or antibiotic intake were collected for Gram stain, culture and antibiotic sensitivity tests. A second urine specimen for culture and sensitivity testing was obtained from those with significant bacteriuria. The results were compared with patients showing negative urine cultures. RESULTS: The overall prevalence of this clinical condition in our study was 13.2%. The significant isolates were Klebsiella pneumonia and E.coli and the most common risk factor was a previous history of urinary tract infection. The isolates were easily identified by using chromogenic agar ( HiCrome ) but colonies of uncommon pathogens like Acinetobacter and Streptococcus species appeared white and needed further identification. CONCLUSION: Screening of pregnant women for AB at first prenatal checkup helps analyse the associated factors and prevents its effects on pregnancy. The use of a chromogenic media can enhance reporting accuracy and will be an effective tool to monitor these cases routinely.

Fusarium Solani: a causative agent of skin and nail infections.

Fusarium spp are non-dermatophytic hyaline moulds found as saprophytes and plant pathogens. Human infections are probably a result of various precipitating predisposing factors of impaired immune status. Immunocompetent individuals of late are also vulnerable to various unassuming saprophytic and plant pathogens. To stress the need to identify correctly and institute appropriate antifungal therapy in newly emerging human fungal infectious agents. Repeated mycological sampling of the skin and nails of the suspected fungal infection were processed as per the standard format including direct microscopy and fungal culture on Sabouraud's dextrose agar. The fungus was isolated as Fusarium solani. Fusarium is an important plant pathogen and soil saprophyte. Infection is acquired by direct inoculation or inhalation of spores. It is associated with a variety of diseases like keratitis, onychomycosis, eumycetoma, skin lesions and disseminated diseases.

Melioidotic pericardial effusion.

Aim is to present a rare case of purulent pericardial effusion caused by Burkholderia pseudomallei. Pericardial sample was inoculated into Bactec Peds Plus/F broth of the Bactec automated system. After the system flagged positive, the broth was subjected to Gram stain, biochemical tests and drug susceptibility. The organism was identified as Burkholderia pseudomallei. Tuberculosis (TB) is the most common cause of pericarditis in countries where it remains a major public health problem, but in the western coastal districts of India, clinicians and microbiologists alike must be aware of Burkholderia pseudomallei a rare cause of pericarditis that can be misdiagnosed as TB pericarditis.
