Influencer marketing: When and why gen Z consumers avoid influencers and endorsed brands
Consumer avoidance of brands and influencers is a widespread phenomenon, especially among Generation Z (Gen Z); however, influencer marketing literature lacks clarity about when and why Gen Z engages in such avoidance. Our experimental investigation, across four studies, reveals that Gen Z considers brands' control over influencers to be morally irresponsible and, thus, avoids both. We introduce a novel construct, influencer avoidance, and examine its drivers. Study 1 indicates that perceived brand control engenders avoidance; moderation evidence shows that macro (vs. micro) influencers accentuate (attenuate) the influence of brand control on avoidance. Study 2 shows that Gen Z enjoying a strong versus weak relationship with influencers results in lower (higher) avoidance towards influencers and endorsed brands. Study 3 demonstrates that negative moral emotions mediate the relationship between perceived brand control and avoidance behavior. Study 4 generalizes the findings by analyzing a different influencer and endorsed brand and including a prominent advertisement disclosure. By investigating the drivers and mechanisms of Gen Z's avoidance behavior, our research contributes to research on the theory of moral responsibility, Gen Z's influencer avoidance behavior, and anti-consumption literature. This offers key insights into how to prevent acts of consumer retribution towards influencers and brands
Nasal Carriage and Antimicrobial Susceptibility of Staphylococcus aureus in healthy preschool children in Ujjain, India
<p>Abstract</p> <p>Background</p> <p>There is increasing evidence that community acquired <it>S. aureus </it>infections are spreading among healthy children. Nasal colonization with <it>S. aureus </it>plays pivotal role in the increasing prevalence of resistant community acquired <it>S. aureus </it>infections worldwide. A regular surveillance system is important in ensuring quality of patient care. The aim of the study was to assess the prevalence of and the factors associated with nasal carriage of <it>S. aureus </it>and its antibiotic sensitivity pattern among healthy children in Ujjain, India.</p> <p>Methods</p> <p>A prospective study was done in paediatric outpatient clinics of R.D. Gardi medical college Ujjain, India. Healthy children from 1 month to 59 months of age were included. Information on previously known risk factors for nasal colonization was collected using a pre-tested questionnaire. Swabs from anterior nares were collected and transported in Amies transport media with charcoal and cultured on 5% sheep blood agar. Antibiotic sensitivity tests were performed using Kirby Bauer's disc diffusion method according to performance standards of Clinical and Laboratory Standard Institute guidelines.</p> <p>Results</p> <p>Of the 1,562 children from 1-month up-to five years of age included in the study 98 children tested positive for nasal carriage of <it>S. aureus</it>. The prevalence of nasal carriage of <it>S. aureus </it>was 6.3% (95% CI 5.1-7.5) out of which 16.3% (95% CI 8.9-23.8) were methicillin-resistant <it>S. aureus </it>(MRSA). The factors associated with nasal carriage were "child attending preschool" (OR 4.26, 95% CI 2.25-8.03; <it>P </it>= 0.007) or "school" (OR 3.02, 95% CI 1.27-7.18; <it>P </it>< 0.001) and "family size more than 10 members" (OR 2.76 95% CI 1.06-7.15; <it>P </it>= 0.03). The sensitivity pattern of isolated <it>S. aureus </it>showed resistance to commonly used oral antibiotics while resistance to glycopeptides was not noted.</p> <p>Conclusions</p> <p>We found a relatively low rate of nasal carriage of <it>S. aureus </it>in children below five years when compared to children of older age groups in India. Yet, prevalence of MRSA was relatively high.</p
Observations on Carbapenem Resistance by Minimum Inhibitory Concentration in Nosocomial Isolates of Acinetobacter species: An Experience at a Tertiary Care Hospital in North India
Acinetobacter species are emerging as an important nosocomial
pathogen. Multidrug-resistant Acinetobacter spp. has limited the option
for effective treatment. Although carbapenems are effective for the
treatment of such infections, resistance to this drug has recently been
reported. This study was undertaken to assess resistance to carbapenem
in clinical isolates of Acinetobacter spp. from hospitalized patients
by both discdiffusion and minimum inhibitory concentration (MIC)
methods. All clinical samples from suspected cases of nosocomial
infections were processed, and 265 isolates were identified as
Acinetobacter species. These isolates were tested for antibiotic
resistance by the disc-diffusion method with 14 antimicrobials,
including meropenem and imipenem. Thereafter, all Acinetobacter species
were subjected to MIC for meropenem. More than 80% resistance to
second- and third-generation cephalosporins, aminoglycosides, and
quinolones was recorded. Thirty percent of the strains were resistant
to cefoperazone/sulbactam. Resistance to meropenem was observed in 6.4%
of Acinetobacter spp. while 8.3% of the isolates showed intermediate
resistance detected by MIC. All carbapenem-resistant/intermediate
strains were also resistant to other (>10) antibiotics tested by the
disc-diffusion method. The rising trend of resistance to carbapenem
poses an alarming threat to the treatment for such infections. Regular
monitoring, judicious prescription, and early detection of resistance
to carbapenem are necessary to check further dissemination of drug
resistance in Acinetobacter spp
Increased prevalence of extended spectrum β lactamase producers in neonatal septicaemic cases at a tertiary referral hospital
Emergence of extended spectrum β lactamases (ESBLs) producing
strains of gram negative bacteria, as one of the leading cause of
septicaemia often complicates the clinical and therapeutic outcome. The
present study was undertaken to investigate the prevalence of ESBLs in
bacteria isolated from neonatal septicaemic cases along with their
antimicrobial sensitivity pattern. Blood samples were collected from
243 suspected cases of neonatal septicaemia. Apart from susceptibility
testing, all the gram negative isolates were subjected to phenotypic
tests for ESBL production. Amongst the positive test samples (n = 115),
84 were gram negative rods. ESBL was detected in 26 (32%) isolates.
Results indicate that routine ESBL detection should be made imperative
and empirical use of third generation cephalosporins must be
discouraged
Observation on integron carriage among clinical isolates of Klebsiella pneumoniae producing extended-spectrum β-lactamases
Purpose: Klebsiella pneumoniae is considered an important pathogen
causing nosocomial and community-acquired infections and is often
associated with the production of extended-spectrum β-lactamases
(ESBL) belonging to SHV and CTX-M families, which are frequently
described as a part of complex integrons, facilitate their horizontal
transfer to other related as well as unrelated microbes. The present
study was undertaken to investigate the occurrence and characterization
of integrons among K pneumoniae isolates producing ESBL in a tertiary
referral hospital. Materials and Methods: A total of 136 clinical
isolates of K pneumoniae were investigated for the presence of ESBL.
Their ESBL genes were characterized by multiplex polymerase chain
reaction (PCR). Integrase gene PCR was performed to detect the presence
of integron. The isolates were further typed by random amplification of
polymorphic DNA (RAPD). Result: Out of 136 K pneumoniae isolates, 63
(46%) were confirmed to be ESBL producers. SHV (68%) and CTX-M (67%)
ESBL genes were the most common in our study. Of the 63 ESBL-positive
isolates, 58 (92%) strains carried integrons; 52 strains (82%) carried
only class 1 integron, whereas 6 (9%) isolates harboured both class 2
integrons and the class 1 gene. However, in ESBL negatives, only 29
(40%) strains were positive for class 1 integron and none for class 2
integron. Conclusion: The presence of class 2 integron amongst
ESBL-producing K pneumoniae is being described for the first time in
this part of the world. The findings of this study strongly suggest
that integrons have a role in the dissemination of ESBL-mediated
resistance among the nosocomial isolates of K pneumonia
