community-acquired pneumonia and brucellosis are of the main agents causing mortality in the world. the most important limitations for the identification of these agents include their high resistance against environmental conditions, impossibility of rapid and on time diagnosis, low level of infective dose, and lack of existence of vaccine against many types of them. hence, on time action and d...

definitive diagnosis of brucellosis is made by isolation of the causative agents, which is a timeconsumingprocedure. to evaluate the efficacy of dot-elisa for detecting brucellae in clinical samples, 94different specimens taken from animal origin were cultured on brucella selective culture media and colonieswere identified biochemically. the specimens were also examined after centrifugation by ...

A PCR assay with primers derived from the 16S rRNA sequence of Brucella abortus was developed. Nine different combinations between six primers were tested. One pair of primers, which amplified a 905-bp fragment, was selected. As little as 80 fg of Brucella DNA was detected by this method. DNAs from all of the representative strains of the species and biovars of Brucella and from 23 different Br...

A whole-cell hybridization assay with fluorescent oligonucleotide probes derived from the 16S rRNA sequence of Brucella abortus in combination with flow cytometry has been developed. With the three fluorescent probes selected, a positive signal was observed with all the representative strains of the species and biovars of Brucella and with a total of nine different Brucella clinical isolates. U...

We examined the blood of 94 North American Chronic Fatigue Syndrome (CFS) patients using forensic polymerase chain reaction and found that a subset (10.6%) of CFS patients show evidence of Brucella spp. infections compared to one of 70 control subjects (Odds Ratio = 8.2, Confidence Limits 1-66, P<0.01). Rural patients showed a higher incidence of Brucella spp. infections over urban patients (OR...

Brucellosis is the lion's share of infectious disease of animals and it has a particular socio-economic importance for the Republic of Kazakhstan. Sixty percent of epizootic outbreaks of brucellosis identified in the Commonwealth of Independent States (CIS) originated from Kazakhstan in recent years. Definitive diagnosis of brucellosis remains a difficult task. Precisely for this reason, we eva...

Three culture media (Brucella agar, Farrell medium, and CITA) were compared for their effectiveness in inhibiting contamination and for isolating Brucella spp. One hundred lymph nodes from pigs (n = 50) and wild boars (n = 50) with lymphadenitis were collected in slaughterhouses in the State of São Paulo and were assessed on these three selective media for Brucella spp. All of the samples were ...

The patterns of susceptibility to hydrophobic and hydrophilic drugs and the uptake of the fluorescent probe N-phenyl-naphthylamine in Brucella spp., Haemophilus influenzae, Escherichia coli, and deep rough Salmonella minnesota mutants were compared. The results show that the outer membranes of smooth and naturally rough Brucella spp. do not represent barriers to hydrophobic permeants and that t...

A study was conducted in order to evaluate the contamination by Brucella spp. of meat from animals slaughtered because they had resulted positive for brucellosis at some time during their life. After slaughter and before delivery to market outlets, swab samples were taken from 307 carcasses of infected animals: 40 cattle, 60 sheep and 207 goats. The swabs were subsequently analysed by means of ...

Splenic abscess due to Brucella spp. is extremely rare. We report a case of a splenic abscess due to Brucella spp. in a 61-year-old male patient. Brucella slide and tube agglutination tests (Wright) were positive while blood culture and culture from splenic tissue yielded negative results. The abdominal ultrasonography revealed a hypoechoic intrasplenic mass 15x12 mm in diameter at the middle p...
