The predominant form is classic type galactosemia caused by severe reduction or absence of the galactose- 1-phosphate uridyl transferase (GALT) enzyme. Coexistence of extrahepatic biliary atresia (EHBA) with Duarte 1 and 2 variants of galactosemia has not been described earlier. Here we report a case of EHBA with concordant Duarte 1 and 2 variants of galactosemia in an infant with cholestasis. Genetic analysis of the index patient for galactosemia revealed presence of Duarte 1/Duarte 2 variants of galactosemia with genotype N314D-L218L/N314D-G1105C-GI391A- G1323A-5’UTR-119delGTCA. Clinical evaluation of the patient showed the presence of EHBA. Henceforth, it may be hypothesized that EHBA may have a genetic basis with simultaneous involvement of the GALT gene.展开更多

The prevalence of Campylobacters in and around Chandigarh, India was studied by phenotypic and genotypic methods. Fecal samples from 1145 diarrheal patients and 102 healthy subjects from hospital and community were cultured on Campylobacter media and identified by Gram stain, biochemical investigations and serotyping. Molecular identification of Campylobacter isolates was done using specific primers to unique regions of 16S rRNA, Campylobacter jejuni (hipO), Campylobacter coli (aspK), Campylobacter lari (glyA) and Campylobacter upsaliensis (lpxA) genes. Identification of specific genes to look for resistance to nalidixic acid, ciprofloxacin, tetracyclin and streptomycin was also done. Campylobacters were isolated from 2.6% of patients with diarrhea. Campylobacteriosis was more prevalent in children ≤5 years old and during summer season. The most frequent serotypes were S:27, B:2, Z5:52 and V:32. All the Campylobacters isolated by culture were confirmed genotypically by identification of 16S rRNA, hipO and aspK genes. Of the 30 isolates, 27 were C. jejuni and 3 were C. coli. No C. lari or C. upsaliensis were detected. Antibiotic resistance was 40% for nalidixic acid, 23.3% for ciprofloxacin, 50% for tetracyclin and 20% for streptomycin. Campylobacter prevalence is low in the region with C. jejuni being the most common species. A high degree of resistance was found for nalidixic acid and tetracyclin but moderate for ciprofloxacin and streptomycin.展开更多
