Apodemus （mice） and rattus （rats） are the top rodent reservoirs for zoonoses in China,yet little is known about their diversity.We reexamined the alpha diversity of these two genera based on a new collection of specimens from China and their cyt b sequences in GenBank.We also tested whether species could be identified using external and craniodental measurements exclusively.Measurements from 147 specimens of Apodemus and 233 specimens of rattus were used for morphological comparisons.We analysed 74 cyt b sequences of Apodemus and 100 cyt b sequences of rattus to facilitate phylogenetic estimations.Results demonstrated that nine species of Apodemus and seven species of rattus,plus a new subspecies of rattus nitidus,are distributed in China.Principal component analysis using external and craniodental measurements revealed that measurements alone could not separate the recognized species.The occurrence of rattus pyctoris in China remains uncertain.

The appearance and hair color between these two subspecies rattus rattus Sladeni and R.r. Hainanicus are similar to each other. Their most major distinctive characteristic is the length ratio of tail to body. However, this characteristic was unstable in some measuring records. In Guangdong, R.r. Hainanicus is restrictedly distributed in the west region, and R.r. Sladeni is widely distributed in the other regions of this province. In this study, we detected the sequences of mitochondrial 12S rRNA gene fragments of 9 samples from R.r. Hainanicus and R.r. Sladeni (Longmen and Hong Kong populations). These 385 nucleotide positions of 12S rRNA gene fragment include 26 variable sites and 14 parsimony-informative sites. 3 insertion/deletion sites are observed. The phylogenetic relationships among these samples were constructed by Neighbor-joining and Maximum parsimony methods. The analysis shows that R.r. Hainanicus is more closely relative to the Longmen population of R.r. Sladeni than to the Hong Kong population of R.r. Sladeni. The sequencing analysis of 12S rRNA gene fragments is not agreement on the classification of subspecies R. r. Hainanicus inferred from the morphology and geographical distribution. The morphological variation of R.r. Hainanicus should result from the natural selection, which causes local adaptation and geographic isolation.

Rodents such as rattus rattus and rattus norvegicus have adapted to living close to human settlements[1].This presents a public health challenge as these rodents are considered as pests that can transmit a number of zoonotic diseases to humans[1,2].A rodent surveillance programme was initiated between the years 2014 and 2015,focusing on rodents captured at wet markets where there is abundant food and considerable human traffic.The present study was conducted in several wet markets in Kuala Terengganu,Malaysia(5.3333°N,103.1500°E).

农田鼠害生物防治的可行性是人们非常关心的问题,也是鼠害综合防治的一个重要环节。本文着重从食性入手,观察研究了珠江三角洲黄毛鼠天敌滑鼠蛇的食性,以及其摄食量与温度、湿度的关系;并且还对黄毛鼠的另一类天敌(号鸟)类的食量情况作了初步观察。提出了对天敌在黄毛鼠生物防治的作用应采取一分为二的态度,一方面不宜过高估计其灭鼠作用,另一方面也应禁止捕捉鼠类天敌,保护其生活环境,维持生态平衡。

小家鼠和褐家鼠在小型啮齿动物中是现今世界上与人类关系最为密切、分布最为广泛的种类。动物学界认为,这2种鼠科动物均起源于中国,然后随着人类活动进行迁徙,逐步扩散到现今世界上所有人类活动区域。由于这2种鼠科动物化石研究材料稀少,以前在古生物或兽类研究中,还缺少对这2种动物从进化方面进行专门研究。本文综合此前中国已报道的小家鼠和褐家鼠化石材料,对它们的早期出现、体质形态变化与迁徙现象等进行探讨。

Objective:To survey the Angiostrongylus cantonensis(A.cantonensis) or the rat lungworm in a rat,definitive host,and in a giant African land snail(Achatina fulica),the intermediate host,in Phitsanulok,Thailand.Methods:Rats and giant African land snails were captured from Tha Pho sub-district,Phitsanulok,Thailand.Rats were killed and examined for adult A.cantonensis. The artificial digestion method following Baermann technique were used for isolation third stage larvae of A.cantonensis.Results:Sixty-two rats were captured and they were identified as rattus argentiventer,rattus rattus(R.rattus),Bandicota savilei,and Bandicota indica but only one animal(R.rattus) of 62 rats(1.61%) was positive with adult worm of A.cantonensis.The third stage larvae of A.cantonensis were examined on 307 Angiostrongylus fulica snails.It was found that the overall infection rate was 12.38%(38 infected out of 307 Achatina snails).Conclusions: This study demonstrates that A.cantonensis is available in the natural hosts of Phitsanulok.This suggests that the transmissions of this parasite to human may occur in this region.

Objective: To report the renal histological lesions in synanthropic rodents, Mus musculus and rattus rattus, naturally infected with Leptospira spp., captured in a rural community in Yucatan, Mexico. Methods: Kidney samples of synanthropic rodents were collected from a rural community in Yucatan, Mexico. Polymerase chain reaction was used to detect Leptospira spp. infection. Tissue kidney was fixed in 10% buffered formalin, processed according to the usual techniques for paraffin inclusion, cut and stained with hematoxylin and eosin, and examined using a conventional electronic microscope. Results: A total of 187 rodents were captured. Nine individuals(4.8%) were positive for Leptospira spp. in the molecular analysis. All renal lesions observed in the histopathological study had been reported previously for Leptospira spp. infection. Conclusions: The histopathological lesions are present in the kidneys, plus the results of the polymerase chain reaction confirm that these rodents are true carriers of Leptospira spp.

Objective:To explore the antispermatogenic and testicular antisleroidogenic activities of Feronia limonia fruit pulp southern India.Methods:Fourty Wistar male albino rats(Ratios norvegicus)were equally divided into four groups.Experimental groups were administered with the ethanolic extract of Feronia lirnonia(F.limoni)fruit pulp at doses of 250 and 500 nig/kg body weight once daily for 55 days.All treated rats had corresponding recovery groups.At the end of each treatment periods,various spermatological indices,tissue biochemicals and testicular enzymes levels were analysed.Blood profiles were also estimated.Results:Compared with the control,the F.lirnonia.fruit pulp at both dose leveb did not decrease body weight,which were associated with decline in epididymal sperm count,motility,viability and increased percent of abnormal sperm.Further,F.limonia.fruit pulp at 500 mg/kg body weight markedly reduced the epididymal and testicular protein content by 24.58%and 29.86%,respectively,as well as the glucose-6-phosphate dehydrogenase and△~5-3β-hydroxy steroid dehydrogenase)levels by 42.82%and 38.08%,respectively,while a significant elevation was observed in testicular cholesterol and ascorbic acid content.A gradual recovery of all parameters was observed after 55 days of treatment withdrawal.No significant alterations in haematological indices were observed.Conclusions:The present findings indicate that F.lirnonia fruit pulp may have reversible antispermatogenic and antisteroidogenic properties,and could partially support the traditional use as mate contraceptive.

2015新发传染病防治热点研讨会

作者： Ping Huang Guangdong Provincial Center for Disease Control and Prevention

The hemorrhagic fever with renal syndrome(HFRS) as a zoonotic disease threatens public health and its incidence increased sharply for present years in southern China. A survey of HFRS including in both natural hosts and human was conducted in Qingyuan, southern China, during 2011- 2013. It was found that one, two and seven confirmed cases of HFRS occurred in 2011, 2012 and 2013, respectively. Rodent densities ranged between 1.73%-12.2% and the Seoul hantaviruses only in both rattus norvegicus and losea were detected by RT-PCR. The positive ratios in human were serologically 0.95% and 0.94% with IIFA in 2011 and 2013, respectively. Both fragments detected from rattus were highly homologically with those of Seoul hantavirus HB55(96.2%) and L99(95.1%), respectively. It was concluded that HFRS is becoming an emerging and dangerous disease in southern China and it is necessary to further perform molecular characterization of strains isolated from rodents and humans.
