Zoonotic cutaneous leishmaniasis (ZCL), caused by Leishmania major, is a common zoonotic vector-borne disease in Iran. Close contact with infected reservoir hosts increases the probability of transmission of Leishmania parasite infections to susceptible humans. Four gerbil species (Rodentia: Gerbillidae) serve as the main reservoir hosts for ZCL in different endemic foci of Iran. These species include Rhombomys opimus, Meriones libycus, Meriones hurrianae and Tatera indica; while notable infection has been reported in Nesokia indica as well...

Fifty-one specimens of small mammals were collected from different locations of Kerman province, southeastern Iran during 2007 and 2009. They constitute six species of rodents (Meriones persicus, Meriones libycus, Tatera indica, Dryomys nitedula and Mus musculus), one species of Erinaceomorpha (Paraechinus hypomelas) and one species of hare (Lepus europeus). The rate of helminthic infection was 45.1 % among all trapped specimens. In 28 out of 51 hunted specimens no intestinal helminth parasite was found. Of all mammals examined, 15 (29...

BACKGROUND: Interest in Tatera indica rodent arises mostly because it is believed that this species is survived among four subspecies reported from Iran, two of which exist in Khuzestan Province. In addition, it might has a role as reservoir hosts of zoonotic cutaneous leishmaniasis in the transmission of Leishmania major in some of the widespread Asian foci including southwestern Iran. METHODS: Diagnostic morphological and molecular markers for T. indica were sought by characterizing from individual specimens, such as some taxonomic features and mitochondrial cytochrome b gene that had previously proven useful for the taxonomy of rodents...

L1 distribution in mammal's genomes is yet a huge riddle. However, these repetitive sequences were already found in all chromosomic regions, and in general, they seem to be nonrandomly distributed in the genome. It also seems that after insertion and when they are not deleterious, they are always involved in dynamic processes occurring on that particular chromosomic region. Furthermore, it seems that large-scale genome rearrangements and L1 activity and accumulation are somehow interconnected. In the present study, we analysed L1 genomic distribution in Tatera gambiana (Muridae, Gerbillinae), Acomys sp...

A continuous serological and bacteriological surveillance in rodents was carried out in peninsular India i.e. Andhra Pradesh, Karnataka and Tamil Nadu to detect the role of different species of rodents in the maintenance of active enzootic plague foci. Live rodents were collected from wild and ruderal/peri-domestic situations by digging and trapping for sera and organ samples. During 1989 to 2007 serological evidence of plague was detected in different species of rodents in peninsular India. Plague antibodies were detected in 243 sera samples in three different rodent species...

Desmodillus and Gerbilliscus (formerly Tatera) comprise a monophyletic group of gerbils (subfamily Gerbillinae) which last shared an ancestor approximately 8 million years ago; diploid chromosome number variation among the species ranges from 2n = 36 to 2n = 50. In an attempt to shed more light on chromosome evolution and speciation in these rodents, we compared the karyotypes of 7 species, representing 3 genera, based on homology data revealed by chromosome painting with probes derived from flow-sorted chromosomes of the hairy footed gerbil, Gerbillurus paeba (2n = 36)...

Daily life of wild mammals is characterized by a multitude of attractive and aversive stimuli. The hippocampus processes complex polymodal information associated with such stimuli and mediates adequate behavioral responses. How newly generated hippocampal neurons in wild animals contribute to hippocampal function is still a subject of debate. Here, we test the relationship between adult hippocampal neurogenesis (AHN) and habitat types. To this end, we compare wild Muridae species of southern Africa [Namaqua rock mouse (Micaelamys namaquensis), red veld rat (Aethomys chrysophilus), highveld gerbil (Tatera brantsii), and spiny mouse (Acomys spinosissimus)] with data from wild European Muridae [long-tailed wood mice (Apodemus sylvaticus), pygmy field mice (Apodemus microps), yellow-necked wood mice (Apodemus flavicollis), and house mice (Mus musculus domesticus)] from previous studies...

The seasonal abundance of Dinopsyllus lypusus Jordan and Rothschild and Ctenophthalmus calceatus Waterson (potential vectors of plague in southern Africa) were studied on rodent hosts captured in selected habitat types of two periurban suburbs of Harare, Zimbabwe. Removal trapping was used to capture the rodents, from which fleas were collected and identified. Prevalence (proportion of animals infested) and specific flea index (SFI = number of fleas per animal) were calculated for each species of rodent host...

Human cutaneous leishmaniasis is one of the most challenging public health issues in many tropical and subtropical countries of the world, including Iran. More than half (54%) of the new zoonotic cutaneous leishmaniasis (ZCL) cases among the Eastern Mediterranean countries were reported from Iran in 2008. The detection of Leishmania parasites in rodents is essential to incriminate them as probable reservoir hosts of ZCL infection. As a result of the annual detection of about 200-250 clinical ZCL cases in the Jask district of southern Iran, feral rodents were trapped, identified to species level, and examined for Leishmania presence by preparing routine blood smears on microscopic slides from 2007 to 2008...

Gerbillus nanus Blanford, 1875 known as Baluchistan gerbil, is a granivorous solitary naked-footed species. No evidence of its natural infection with the protozoan parasite, Leishmania, has so far been provided. Cutaneous leishmaniasis (CL) is a major public health problem in many parts of the world, including Iran. The annual nationwide incidence of human CL due to Leishmania major (CLM) in endemic rural areas was above 18,000 cases in 2008. The detection of L. major in rodents is of fundamental importance for incriminating them as potential reservoirs of CLM infection...

The Boston Model describes a successful rodent management plan that succeeded in a first-world city in the USA. In third-world cities, which often contain informal shack settlements, it is debatable whether the Boston Model would apply. In Durban, a major harbor city of three million people on the east coast of South Africa, we investigated the sanitary risks due to rodents in both formal (residential and commercial) and informal (shacks) sectors, and we evaluated the relative merits of different management interventions suggested by the Boston Model...
