An illustrated identification key to the North American termite families and genera based mainly on soldier caste is proposed. A checklist of termites (Insecta: Blattodea: Isoptera) Canada, continental USA Mexico presented, listing 89 species (and two subspecies) grouped in 26 four families. Five are added Mexican fauna, these records for states Campeche: Cryptotermes cavifrons; Quintana Roo: c...

Microbiological quality control of 13 pollen samples purchased from local markets and 2 other samples provided by apiarists was investigated. TAMC ranged from 3.00 to 5.48 Log CFU/g. TMYC was between 2.3 and 6.99 Log CFU/g. Staphylococcus aureus was recovered with high density in 14 samples (up to 8.32 Log CFU/g) and Enterobactericeae count ranges from 4.18 to 8.018 Log CFU/g. Moreover, Salmone...

The in vitro activity of sparfloxacin, a new quinolone, was compared with those of ciprofloxacin and fleroxacin against gram-positive and gram-negative bacteria, greater than 90% of which were isolated from blood culture specimens of cancer patients. Sparfloxacin was extremely active against Acinetobacter species, Aeromonas hydrophila, Citrobacter diversus, Enterobacter species, Escherichia col...

Growth of Neisseria gonorrhoeae from clinical specimens has been enhanced by the use of selective media that inhibit the simultaneous growth of other microorganisms. One explanation for this enhancement could be that certain other bacteria inhibit gonococcal growth. This hypothesis was examined by testing 167 bacterial isolates for in vitro gonococcal inhibition; 34.1% of the isolates failed to...

Primary abdominal wall abscess is extremely rare and difficult to diagnose because abscesses usually occur secondary malignant tumors or inflammatory diseases. We experienced a case of an 80-year-old man with asynchronous primary recurrence. Both were successfully treated surgical drainage. A patient without any history cancer trauma presented our department right upper pain. His laboratory dat...
