Steinernema feltiae isolate IRAZ13 was recovered from one soil sample collected from the Arasbaran forests, Iran. The new isolate can be distinguished from other isolates by morphologic and ...morphometric data, and DNA sequences. The first generation male is characterized by spicule length 79 ± 5 (73–87) μm, SW ratio (spicule length/anal body diameter)*100 160 ± 13 (137–177), GS ratio GS (gubernaculum/spicule length)*100 79 ± 8 (62–87), genital papillae arrangement and the second generation male by a mucron 10 ± 1 (9–11) μm long. For the infective juvenile, the body is 883 ± 82 (754–975) μm long, lateral fields with eight equally developed ridges, head smooth, slightly offset, large gonad primordium cells, a long hyaline tail portion (equal to half of tail length), and pore-like phasmid at 41% of the tail length to the semicircle anus are the differentiation factors. Additionally, molecular studies obtained from the 28S-D2/D3 region and ITS1 rDNA sequence analyses and phylogenetic reconstruction further support this nematode as a different isolate.
Abstract
A survey for entomopathogenic nematodes (EPN) was carried out in the
Arasbaran forests and rangelands, East Azarbaijan province, north-west Iran,
during 2006 to 2008. A total of 691 soil ...samples were collected from 62
localities across the region of which 21 samples (3%) were positive for EPN,
including nine samples (1.3%) with heterorhabditids and 12 (1.7%) with
steinernematids. Seven isolates (four Steinernema and three Heterorhabditis)
were recovered from rangelands and 14 (eight Steinernema and six
Heterorhabditis) from forest soil samples. Based on morphology and molecular
studies, the Heterorhabditis isolates were identified as H. bacteriophora
and the Steinernema isolates as S. carpocapsae, S. bicornutum, S. feltiae,
S. glaseri, S. kraussei and three undescribed species referred to here as
Steinernema sp. IRAZ7, Steinernema sp. IRAZ13 and Steinernema sp. IRAZ21.
Heterorhabditis bacteriophora, the most common species, was present in nine
soil samples collected across the forests and rangelands, and of the
Steinernema species, S. bicornutum was obtained from three samples, the
other species being found from only one or two samples.
In this research, in order to study the effect of different concentrations of IBA and time of taking cutting on rooting, growth and survival of F. binnendijkii ‘Amstel Queen’ cuttings, a test was ...conducted in a randomized complete block design with four replications. Treatments were consisted of four levels of hormones: 0 (control), 2000, 4000 and 6000 mg/l, with two intervals of time for taking cuttings (late June and early September). Results showed that highest root percentage, root number and fresh weight of root were for IBA concentrations of 4000 and 6000 mg/l and cuttings taken early in September. The maximum of mean length of root and longest root were achieved in concentration of 6000 mg/l IBA, taking cutting in early September. The highest survival percentage of plants was recorded in concentrations of 4000 and 6000 mg/l IBA, early September being the appropriate time of taking the cutting. The greatest length of new shoots was obtained in concentration of 4000 mg/l IBA, cutting in late June, while the maximum number of new leaf was in IBA concentration of 2000 and 4000 mg/l, with cuttings taken also in late June.
The aim of this study was to assess the etiological characteristics and visual outcomes of ocular trauma with more attention to eyelid laceration.
In a cross-sectional study, 98 cases of isolated ...traumatic eyelid laceration were consecutively studied and its epidemiology, etiology and association with visual outcome were evaluated. The findings of this study could be used to develop healthcare related precautions and work place safety recommendations.
Of the 98 patients included in the study, men exhibited a greater vulnerability and they were mostly aged around 29 years old. In terms of the place of trauma, 40 (43.5%) cases occurred in the street, 27 cases (29.3%) occurred at home, and 17 cases (18.5%) occurred at the workplace, while 4 cases (4.3%) happened in entertaining environments like parks. For 3 patients (3.3%), the incident took place at a public pathway, and in 1 patient (1.1%), the case occurred at school. As the most common cause of trauma, 41 patients (42.3%) had an object hit their eyes. In addition, assaults were a major cause of injury. The right eye and the upper lid were also the most common sites of injuries. Although no blindness occurred due to trauma causing eyelid laceration, the visual outcomes were correlated with severity of the incident defined based on the presence of open globe injuries.
This study could possibly highlight the risk factors of eyelid laceration and provide the healthcare community with the essential recommendations regarding the safety precautions in dangerous settings, including daily / routine work places.
