In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...
BACKGROUND Klebsiella pneumoniae is a prominent nosocomial pathogen that accounts for up to 10 % of all hospital-acquired infections. It is a frequent cause of ventilator-associated pneumonia (VAP). The purpose of this study was to investigate the clinical characteristics of K. pneumoniae-associated VAP and the molecular characteristics of K. pneumoniae strains. METHODS We retrospectively rev...
Neisseria meningitidis is an obligate human commensal that commonly colonizes the oropharyngeal mucosa. Carriage is age dependent and very common in young adults. The relationships between carriage and invasive disease are not completely understood. In this work, we performed a longitudinal carrier study in adolescents and young adults (173 subjects). Overall, 32 subjects (18.5%) had results th...
purpose: to report a case of capsular bag distension syndrome (cbds) with solid material presenting eight years after cataract surgery. case report: a 58-years-old female who underwent an uneventful clear-cornea phacoemulsification with in-the-bag intraocular lens (iol) implantation in the right eye, presented with a chief complaint of blurred vision (va: 20/200) and cobweb like matter appearin...
the aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. a 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. the dog was bitten by a snake nearly 4 months ago. a 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. in the left eye, posterior synechia was detected in the ...
ABSTRACT Background and Objectives: Klebsiella pneumoniae is one of the most important nosocomial pathogens. Its capsular polysaccharide is considered as the first and most important virulence factor of this bacterium. This study aimed to investigate the presence of capsular serotypes K1 and K2 in K. pneumoniae isolates to examine the virulence ...
BACKGROUND 28-43% of the patients develop posterior capsular thickening after extra capsular cataract surgery. Nd-YAG laser capsulatomy is a method of choice to treat this complication. METHOD We conducted a prospective clinical, randomized comparative study to evaluate the post YAG laser IOP rise in 54 patients at Ayub Teaching Hospital Complex. RESULT There were 43% male and 57% female pa...
Background: Pasteurella multocida serotypes A and D are commonly associated with pneumonia and pleuritis in pigs. Different phenotypic techniques, such as hyaluronidase and acriflavine tests, and genotyping techniques, such as PCR, are used to distinguish between these serotypes. The objective of this study was to compare the capsular identification methods of type A and type D P. multocida iso...
The first demonstration of transformation (Griffith, 1928) was concerned with type-specific capsular polysaccharides of pneumococci. Such transformations of capsular types usually are accompanied by a change in colony type since most investigators have studied transformation of R cells which produce little or no capsular material. Coiacomitant transformation of capsular and colony type has been...
