Initial microbial colonization in the alimentary tract of a new – born baby in different modes of parturition

  The intestinal microflora is a positive health asset that crucially influences the normal structural and functional development of the mucosal immune system. In the new born, the colonization of microbes in the alimentary system starts as soon as the womb comes out. A study on the early colonized bacterial species in a new - born will help to understand the immuno protective functions in the new-born. The...

Evaluation of in vitro solubilization potential of phosphate solubilising Streptomyces isolated from phyllosphere of Heritiera fomes (mangrove)

  Phosphate solubilising ability of five Streptomyces isolated from the phyllosphere ofHeritiera fomes grown in Bhitarkanika mangrove ecosystem  was evaluated  using tricalcium phosphate (TCP) in both plates and broth culture conditions as well as with and without NaCl. Streptomyces ST24 showed highest solubilization of TCP, with 50.8 and 48.0 mm of halo zone in the plate...

Fungi associated with deterioration of sour-sop (Anona muricata Linn.) fruits in Abia State, Nigeria

  Anona muricata commonly known as sour-sop, belong to the family Annonaceae. It is a small slender tropical tree usually grown for its large fleshy and juicy fruits. The fruit of A. muricata plays an important role in the diet of many in many parts of the tropics including Nigerian. Unfortunately, the usefulness of the fruits of Anona is decimated by many fungi species. Investigation...

Bacterial contamination of crockery and cutlery within the kiosks’ restaurants of the Federal University of Technology, Yola

  An investigation was undertaken to determine bacteriological quality of crockery and cutlery of seven restaurants in Federal University of Technology, Yola (FUTY) kiosk. Samples (147) were collected and cultured in appropriate media and the bacterial isolates were identified according to their morphological and biochemical characteristics. The result revealed a profile of seven (7) different bacterial species...

Extracellular leucine aminopeptidase produced by Aspergillus oryzae LL1 and LL2

  In a screen of 175 fungal strains, Aspergillus oryzae LL1 and LL2 were identified as having the highest extracellular leucine aminopeptidase (LAP) activity. LAP activity was optimal when A. oryzae LL1 was subjected to submerged fermentation with an inoculum size of 105 spores per ml and an agitation of 100 rpm at 30°C in media containing defatted soybean and rice husk with a...

Predominant lactic acid bacteria associated with the traditional malting of sorghum grains

  The traditional processes of sorghum grains malting were investigated in Tamale (Northern Ghana) from the raw materials through to the sun-dried malted sorghum including steeping and germination stages. Samples were taken at each processing stage and cultured for the isolation of LAB. The isolates were characterized by basic phenotyping, ITS-PCR / RFLP analysis and identified by partial sequencing of 16S r...

A comparative study on biofilm formation of non-typeable Haemophilus influenzae and Pseudomonas aeruginosa under single culture or co-culture

  Individual bacteria can accumulate to form biofilm which can help bacteria escape from host immune defense and many antimicrobial agents. Therefore biofilm involves a large number of bacteria which can induce chronic diseases. Here, we compared the differences of biofilm formation among Nontypeable Haemophilus influenzae(NTHi) single culture condition, Pseudomonas aeruginosa (P. aeruginosa) single...

Degradation of dichlorodiphenyltrichloroethane (DDT) by bacterial isolates from cultivated and uncultivated soil

  The re-introduction of dichlorodiphenyltrichloroethane (DDT) to control mosquitos was recommended by the World Health Organization in 2007. In this study, the potential for biodegradation of DDT by soil microorganisms through enrichment and isolation of DDT biodegraders from soils without a history of prior exposure to DDTwas done. Microorganisms from cultivated and uncultivated soils grew in...

Seroprevalence of Crimean-Congo haemorrhagic fever (CCHF) in risk groups in Tokat Province of Turkey

  Crimean Congo Haemorrhagic Fever (CCHF) is a fatal viral haemorrhagic fever affecting humans. Serious CCHF outbreaks with high mortality have been reported from Asia, Africa and Europe. Endemic CCHF outbreaks have been seen in Turkey between 2002 and 2009, with about 5% mortality rate. People working with animals, people having tick bites, health workers and relatives of CCHF patients may be infected by CCHF...

Cloning and phylogenetic analysis of bovine leukemia virus gag gene in Iranian isolate

  Bovine leukemia virus (BLV) is a member of the family Retroviridae, genusDeltaretrovirus that has three important gene including gag, pol and env. This virus causes B-cell lymphocytosis and lymphosarcoma in cows. In the first step PCR product of gag gene of BLV isolated in different regions of Iran and BLV-FLK strain was cloned into a pTZ57R/T vector, then insert were digested by BglII...
