Two chromosome-encoded beta-lactamases have been purified from Citrobacter diversus ULA-27. They exhibited slightly different isoelectric points (6.8 and 6.2) and very similar Mr values (congruent to 29,000). Their specificity spectrum was rather wide, since they hydrolysed some cephalosporins with kcat: values similar to those observed with the best penicillin substrates. Cloxacillin, methicil...
The Dufour gland of both queens and workers of Meranoplus diversus is very large. The reservoir is lined with flat epithelial cells, which usually contain smooth endoplasmic reticulum but also show the unusual accumulation of electrondense inclusions. Chemically, the gland contains an unusual mixture of long-chain fatty acids and their derivatives, including hydrocarbons, ketones and amines wit...
موریانه¬ی microcerotermes diversus silvestri (isoptera: termitidae) از آفات مهم محصولات سلولزی در اماکن مسکونی و نیز محصولات کشاورزی در استان خوزستان محسوب می¬شود. ایمیداکلوپرید یک سم از گروه نئونیکوتینوئید هاست که برای کنترل موریانه ها به کار می رود. اما کاربرد مداوم حشره¬کش¬ها می¬تواند منجر به تخریب تدریجی محیط¬زیست گردد. لذا توجه زیادی به شیوه¬های کنترل بیولوژیک جلب شده است. قارچ metarhizium...
In the study antimicrobial activity of adonitol, arabinose, cellobiose, dulcitol, galactose, glycerol, glucose, inositol, lactose, maltose, mannitol, mannose, mellibiose, raffinose, salicin, sorbitol, sucrose, trehalose and xylose was determined on 96 strains of Bacillus anthracoides, 3; Bacillus badius, 5; Bacillus brevis (3), Bacillus circulans (4), Bacillus coagulans (3), Bacillus lentus (6)...
As a result of studies of material of Ecdyonurus from Spain, nymphs and adults of two new species, E. baeticus sp. n. and E. olgae sp. n., are described. Three species described by Navás must be considered as nomina dubia (E. diversus Navás, 1923, E. excelsus Navás, 1927 and E. fluminum var. speciosus Navás, 1915). Variability in adults of E. venosus is figured and discussed.
Citrobacter, a Gram-negative enteric bacillus, is a rare cause of septicemia and meningitis, seldom reported beyond the neonatal period. It is characterized by a fulminant clinical course and a high incidence of complications, including brain abscesses. We studied a three-month-old infant with Citrobacter meningitis, who developed acute communicating hydrocephalus and multiple periventricular b...
Inhibitory activity of cephalexin, cephradine, and cefaclor was compared by the WHO-ICS agar dilution technique. Cefaclor was substantially more active against staphylococci, streptococci, gonococci, meningococci, Haemophilus, Escherichia coli, Klebsiella pneumoniae, Citrobacter diversus, Proteus mirabilis, salmonellae, and shigellae than was cephalexin, which in turn was more active than cephr...
Forty-seven strains of Citrobacter diversus were isolated during a 12-month period from clinical material obtained from patients in a general hospital in Israel. The majority of cultures (38) were recovered from urine and wound discharges. There was one case of septicemia. The biochemical reactions of all cultures were typical for this species, except one that was anaerogenic, and they could be...
