Skin and soft tissue infections (SSTIs) result from microbial invasion and may be mono or polymicrobial in etiology. The present retrospective record-based study described five uncommon SSTIs from a medical college hospital of West Bengal. Clinical samples were collected and processed following standard microbiological procedures and guidelines. Identification and antimicrobial susceptibility testing of etiological agents, wherever applicable, were done by conventional and automated (Vitek-2 Compact) system. We found a case of spontaneous gas gangrene caused by Clostridium septicum, Group-A â-hemolytic Streptococcus mediated necrotizing fasciitis; lesions of Burkholderia pseudomallei and Burkholderia cepacia complex and that of disseminated rhinosporidiosis caused by Rhinosporidium seeberi. We infer that strong clinical suspicion may surface uncommon etiology from unusual presentations of SSTIs making their diagnosis, treatment and relief rapid and uneventful.

Study of biological parameters of a species is important for its sustainable management. The length-weight relationships and growth patterns of Macrobrachium malcolmsonii (H. Milne-Edwards, 1844), collected from the river Old Brahmaputra in Bangladesh, were determined in this study based on 359 specimens (carapace length, CL: 11–90 mm; body weight, BW: 0.2–54.4 g) including 308 male and 351 female individuals. For both sexes, intercepts, slopes, and coefficients of determinations of regression analyses between CL and BW varied monthly. The lowest values of intercept (–11.51 and –11.65 for male and female respectively) was recorded in October whereas the highest values were recorded in January for male (–7.01) and March for female (–8.26 for female). The minimum coefficient of determination was 0.784 (for male) and 0.801 (for female) whereas the maximum coefficient of determination was recorded 0.971 (for male) and 0.970 (for female). For male, the b value at 95% Cl revealed that the growth in March, June, July, September and February were isometric and in April, May, October, November and January were allometric. Whereas for female, the growth in March, April, June, July, November, January and February were isometric and was allometric in May, September and October.
