Study on rodents infestation in Alexandria and prevalence of trichinella spiralis infection among them

Rodents were monthly collected from six districts of Alexandria during the whole year using live traps. The 1025 collected rodents were divided according to species, gender, age and weight. El-Amryia and El- Montaza were the most infested districts, while West, East, Middle and El-Gomrok districts were the lowest infested ones. Rattus norvegicus was the highest abundant species in the city [41.9%], followed by R. rattus [37.2%] then Mus musculus [20.9%]. There was no difference in abundance of rodents during summer compared with winter. Meanwhile, males represented 57.6% of the total collected rodents. Most of the collected rodents were <2 months old [63.8%] or light weighed [61.6%], however, number of caught rodents decreased as age or weight increased. Concerning El-Amryia and EL-Montaza districts where abattoirs are located, number of collected rodents from and around the abattoirs represented 70.4% of the total collected rodents were compared with 29.6% collected from and around the houses of the same districts. The total prevalence of T. Spiralis infection among collected rodents using digestion technique was 13.3%. El-Amryia, El- Montaza, West and El-Gomork Districts were the only infected districts

Evaluation of the health status of fishermen of lake Maryout: 1 parasitic infections

This work was carried out at lake Maryout to study the prevalence of parasitic infections among fishermen. 395 cases were selected randomly, stool and urine samples collected and examined for different parasites. 100 sera from fishermen in different age groups were collected and examined for Toxoplasma gondii infection by IHT. The obtained results indicated that A. lumbricoides and S. mansoni were the most prevalent intestinal parasites among fishermen. As regards Toxoplasma gondii infection a high level of seropositivity was found in examined samples. Cats could play an important role in transmission

role of head lice in transmission of tinea capitis

This study was conducted during Jan 1986 in primary school children in Amreya as a rural area of Alex. The total number of children examined were 350 who were classified into four groups, according to the presence of lice infestation and clinical manifestation of Tinea capitis. Lice were collected by combing the hair and then cultured on the surface of Sabouraud's dextrose for mycological identification. dermatophytic spores were isolated from 40 specimens out of 58 lice specimens [68.97%]. Trichophyton violaceum represented the highest percentage of infection, then Microsporum gypseum and Microsporum canis. This study showed that lice play an important role as a mechanical carrier of different types of dermatophytes and pave the way for fungal invasion through the scratches and abrasions caused by such infestation

Evaluation of merthiolateIodine-formaldehyde concentration [MIFC] technique and the test-tube culture for the detection of ancylostoma duodenale and strongyloides stercoralis

A random sample of 163 stool specimens were collected from Abbis II and Khorshid villages. One portion of the fresh stool was preserved in MIF solution and another one was taken for cultivation by test-tube culture technique. This preliminary study was designed to evaluate the MIF-concentration technique and the test-tube culture for the detection of Ancylostoma duodenale and Strongyloides stercoralis larvae. The obtained results showed that the percentage of Strongyloides stercoralis detection was [0.61%] by MIF-concentration technique while it was [14.72%] by test-tube culture. The difference was statistically significant

Domestic water supplies and community self-help in Sidi Ghazzi area Nile delta A strategy for schistosomiasis control: part III, the acceptability of community participation

With the aim of assessing the acceptance of the concept of community participation by the community, 128 village leaders in Sidi-Ghazy were subjected to a questionnaire survey and a schistosomiasis infection investigation. Results revealed that while sufficient knowledge of the relationship between schistosomiasis and water contact was generally poor, it appeared particularly so in the older age groups. At the same time the more the knowledge the lower was the infection rate. The acceptance of community participation in schistosomiasis infection rate was lower the more the acceptance of community participation in water supplies and maintenance. Conclusively it appears that acceptance of C.P. While currently inadequate could be raised with the up lifting of the standard of knowledge about disease transmission and water contact hazards. Meanwhile, it seems of prime importance that links between the community and governmental sectors involved be strong in order to raise community confidence and self-help

effect of praziquantel on vampirolepis nana: I, in vitro study

The work was designed in order to clarify the efficacy of praziquantel on the adult worms of Vampirolepis nana in vitro. The obtained results revealed that praziquantel at concentration 1.0 ug per ml causes rapid immobilization and strong contractions of the scolex, neck, immature, mature and gravid segments with the release of V. nana eggs in clusters to the surrounding medium

effect of praziquantel on vampirolepis nana: II in vivo study

The work was designed in order to study the effect of praziquantel in the treatment of mice infected with Vampirolepis nana. The results obtained showed that the drug used at a dose of 25 mg per Kg body weight has a lethal effect on both cysticercoids and storability stages of the parasite

Preliminary study on the role of musca domestica in spreading of toxoplasma infection

IFAT technique was performed on mice previously inoculated per OS by an emulsion of flies collected from different districts of Alexandria during summer months for detection of Toxoplasma antibodies

Karish cheese, mech and pickles as vehicles of accidental intestinal myiasis

62 karish cheese, mesh, and pickles samples were collected from Alexandria markets. The samples were examined bacteriologically and parasitologically. The results of the study indicate that the total plate of karish showed an average of 17x10[6]. Coliforms were found in all samples with an average of 79x10[7]/100 gm. 60% were identified as Escherichia Coli. The pH average was 3.6. In mesh sample bacteriological examination was negative. Pickles samples showed that, pH average of 8.6 and total plate count average of 4.2x10[6] and coliforms average of 28x10[3]/100 gm. Eschrichia coli was isolated from all the samples. Karish cheese, mesh cheese and pickles were infested by larvae of P. casei, M. domestica and Calliphora spp. E.coli cyst was found in .15.4% of karish cheese, while E.histolytica cysts were in 16.5% in pickles samples

role of flies in dissemination of dermatophytosis

The present work is an attempt to study the presence of various dermatophyte species on different species of flies which was collected from urban and suburban areas of Alexandria. Different species of flies such as M. domestica, Fannia canicularis Calliphora and Lucilia species were identified from the different samples examined. Mycological examination of flies revealed various species of dermatophytes such as T.mentagrophyts, T.verrucosum, M.canis and T. rubrum in addition to C. albicans detected from one sample of flies. The high number of dermatophyte species isolated is considered another reason for effectively combating flies, and introducing advanced garbage removal systems and correlation between different services to prevent transmission of serious diseases to man
