isolation of bohv-1 was attempted from nasal swabs as well as aborted foetuses and vaginal swabs in madin darby bovine kidney (mdbk) cell line to find out the prevalent strain in the state of west bengal, india. the virus was isolated from only one case out of 65 nasal swabs whereas no virus was isolated from aborted foetuses and vaginal swabs. the isolate was typed as bohv-1.2 (strain india 3).

Experimental aspergillosis was induced in 1-day-old turkeys by intra-air-sac inoculation of a spore suspension of a 3-day-old Aspergillus fumigatus culture (CBS 144.89) containing 10(7) spores. Ten additional poults were used as controls. Infected and non-infected animals were closely observed at least twice a day for the appearance of clinical signs and were sequentially sacrificed at days 1, ...

Leprosy in Colombia is in the post-elimination phase; nevertheless, there are regions of this country where the incidence is still around 3-4/100,000. Early detection of leprosy patients is a priority for achieving control and elimination of leprosy; however, the clinical exam is not very sensitive and thus, the majority of patients are diagnosed only when they demonstrate lesions, and damage t...

Detection of tuberculosis in cattle relies on the intradermal tuberculin test (ITT), but a definitive diagnosis requires identification of the pathogen after the animal is slaughtered. DNA in nasal swabs from 50 cows was analyzed by m-PCR, targeting for the RvD1-Rv2031c and IS6110 sequences. M. bovis was identified in two of 34 tuberculous cows (5.9%). The use of mPCR of nasal swabs as an in vi...

BACKGROUND Self-collection of nasal swabs could improve the timeliness of influenza virus detection in older adults. OBJECTIVES Measure the acceptability, adequacy, timeliness, and validity of self-collected nasal swabs among adults >65 years in Thailand. METHODS Our evaluation consisted of two parts: a one-month study among randomly selected, community-dwelling older adults to simulate com...

The free-living protozoan Acanthamoeba is an opportunistic pathogen that is ubiquitous in our environment. However, its role in affecting indoor air quality and ill-health of indoor occupants is relatively unknown. The present study investigated the presence of Acanthamoeba from the ventilation system and its correlation with other indoor air quality parameters, used in the industry code of pra...

BACKGROUND A better understanding of the epidemiology of nasopharyngeal carriage of Streptococcus pneumoniae is important to assess the impact of vaccination and the pathogenesis of pneumococcal disease. We compared the recovery of S. pneumoniae from nylon flocked, Dacron and rayon swabs. METHODS The recovery of S. pneumoniae from mocked specimens using flocked, Dacron and rayon swabs were co...

Moore swabs (sewer swabs) have been used successfully to culture pathogenic organisms from wastewater. Sensitivity seems to depend on the size of the waterway sampled as well as the number of organisms present. In Santiago, Chile, we placed 24 swabs into the sewers draining the homes of 10 known chronic carriers of typhoid. Swabs were positive for Salmonella typhi in 5 of the 10 households (50%...
