This work characterizes a recently discovered natural tetracycline-resistance plasmid called pMA67 from Paenibacillus larvae--a Gram-positive bacterial pathogen of honey bees. We provide evidence that pMA67 replicates by the rolling-circle mechanism, and sequence comparisons place it in the pMV158 family of rolling-circle replicons. The plasmid contains predicted rep, cop, and rnaII genes for c...

American Foulbrood, caused by Paenibacillus larvae, is the most severe bacterial disease of honey bees (Apis mellifera). To perform genotyping of P. larvae in an epidemiological context, there is a need of a fast and cheap method with a high resolution. Here, we propose Multiple Locus Variable number of tandem repeat Analysis (MLVA). MLVA has been used for typing a collection of 209 P. larvae s...

A new medium, designated TMYGP broth, was developed that allowed the honeybee pathogen Bacillus larvae NRRL B-3650 to produce up to 5 x 10 spores per ml of culture (microscopic count). This species normally sporulates poorly, if at all, in artificial broth media. An aeration rate lower than that normally used to cultivate other Bacillus species was required for sporulation. During the exponenti...

Ichthyoplankton data provide a base for research into population dynamics of major fishery species. Information on ichthyoplankton ecology forms an important component of stock assessment and fishery management plans. Also, nursery areas are important regions for the recruitment success of fishery stocks and as such, conservation of these areas is a key part of fishery management. Temporal dist...

five organo-phosphorous compounds were tested against lab-bred and wild caught larvae of ano pliclcs stcphclisi nrysorcnsis at the kazeroun medical research station, southern iran, during may-june, 1974. this study showed that as the larvae grew their tolerance to the insecticides tested increased up to 5 times more than that of day-old larvae. when iate 3rd and early 4th instal' larvae of wild...

The present work deals with the study of fish larvae of coral reef fishes in the Red Sea (Hurghada). It was aimed to study the spatial and temporal variations of fish larvae for management purposes. Sampling stations were chosen at Marina, Sheraton, Magawish and Arabia. The samples were taken monthly throughout the period of the study from August 2014 to July 2015 using plankton nets of differe...

myiasis is the condition of infestation of the body by fl y larvae (maggots). the deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. it is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. the diagnosis of myi...
