Abstract

The Asian subterranean termite, Coptotermes gestroi (Wasmann 1896) (Isoptera Rhinotermitidae), is a structural pest endemic to Southeast Asia that has been spread anthropogenically to much of the tropics worldwide. We report a land-based establishment of C. gestroi in Alexandria, Egypt, the northernmost locality of this species and over 4000 km from its nearest previous locality in northern India. An earlier study suggested that C. gestroi, misidentified as Reticulitermes lucifugus (Rossi 1792), was in Alexandria in 2010. We confirm C. gestroi in Alexandria based on soldier morphology and COII sequence data. We also report that Coptotermes alexandrinus Mohammad et Ramadan 2023, is a junior synonym of C. gestroi. The world distribution of C. gestroi is presented. [ABSTRACT FROM AUTHOR]

Abstract

Alpha interferon (IFN-α) suppresses human immunodeficiency virus type 1 (HIV-1) replication in vitro by inducing cell-intrinsic retroviral restriction mechanisms. We investigated the effects of IFN-α/ribavirin (IFN-α/riba) treatment on 34 anti-HIV-1 restriction factors in vivo. Expression of several anti-HIV-1 restriction factors was significantly induced by IFN-α/riba in HIV/hepatitis C virus (HCV)-coinfected individuals. Fold induction of cumulative restriction factor expression in CD4(+) T cells was significantly correlated with viral load reduction during IFN-α/riba treatment (r(2) = 0.649; P < 0.016). Exogenous IFN-α induces supraphysiologic restriction factor expression associated with a pronounced decrease in HIV-1 viremia.

Abstract

Abstract Background Several host-encoded antiviral factors suppress HIV-1 replication in a cell-autonomous fashion in vitro. The relevance of these defenses to the control of HIV-1 in vivo remains to be elucidated. We hypothesized that cellular restriction of HIV-1 replication plays a significant role in the observed suppression of HIV-1 in "elite controllers", individuals who maintain undetectable levels of viremia in the absence of antiretroviral therapy (ART). We comprehensively compared the expression levels of 34 host restriction factors and cellular activation levels in CD4+ T cells and sorted T cell subsets between elite controllers, HIV-1-infected (untreated) non-controllers, ART-suppressed, and uninfected individuals. Results Expression of schlafen 11, a codon usage-based inhibitor of HIV-1 protein synthesis, was significantly elevated in CD4+ T cells from elite controllers as compared to both non-controllers (p = 0.048) and ART-suppressed individuals (p = 0.024), with this effect most apparent in central memory CD4+ T cells. Schlafen 11 expression levels were comparable between controllers and uninfected individuals. Cumulative restriction factor expression was positively correlated with CD4+ T cell activation (r2 = 0.597, p

Abstract

The present study aimed to determine the prevalence and distribution of fleainfested ruminants in Egypt's Northern West Coast (NWC) and South Sinai Governorate (SSG), besides the molecular characterization and genotypes of Nematode and Trematode in the identified flea species. In total, 765 animals of both sexes and ages (471 from NWC and 294 from SSG) were examined for flea infestation, including 460 sheep and 305 goats. Microscopically, flea species were identified, while nematodes and trematodes were identified using sequence analysis of purified PCR fragments of the small subunits 18S of nuclear ribosomal DNA (18S rDNA) and the internal transcribed spacer region of the ribosomal RNA (ITS2) gene primers. The results revealed that the cat flea, Ctenocephalides felis, and the dog flea, Ctenocephalides canis, were widely distributed in sheep and goat flocks throughout the corresponding areas. While age, sex, and host had no significant differences (P > 0.5), the location, flea species, and season of flea collection all had an impact on the predominance of the two flea species. Additionally, there were significant differences between C. felis and C. canis infestations in the two areas, and only among the sexes of both flea species in the NWC. Molecular data confirmed one trematode (Fasciola hepatica) in both C. felis and C. canis, whereas two nematode species were identified: Haemonchus contortus only in sheep in both areas and Trichostrongylus colubriformis only in C. canis infesting goats in SSG. Sequenced isolates were assigned in the GenBank database under accession numbers ON123999, ON123994, ON123995, and ON123993 (F. hepatica), ON113484, ON113485, and ON113486 (H. contortus), and ON113498 (T. colubriformis). We conclude that the presence of those pathogens in fleas in the two areas required special attention to periodic flea control programs and anthelmintic treatments, as well as further evaluation of the epidemiology and role of fleas.

Abstract

Background: High frequency of Helicobacter pylori infection and the unknown mode of transmission prompted us to investigate H. pylori–wild housefly relationship. H. pylori causes chronic gastritis, peptic ulcers, and stomach cancer. H. pylori persists in the gut of the experimentally infected houseflies. The existence of H. pylori strains isolated from wild houseflies, on the other hand, has never been documented. Materials and Methods: In this study, 902 wild houseflies from different sites were identified as Musca domestica, then 60 flies were screened by traditional microbiological techniques and H. pylori-specific 16S rRNA gene. The antibiotic resistance (ART) was investigated phenotypically. Wild housefly gut bacterial isolates were further evaluated genotypically to have 23S rRNA gene mutation related to clarithromycin resistance. To find efficient therapeutic alternatives, the potency of three plant extracts (garlic, ginger, and lemon) and the wasp, Vespa orientalis venom was evaluated against H. pylori. The cytotoxic effect of the crude wasp venom, the most potent extract, against Vero and Colon cancer (Caco2) cell lines was investigated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Results: All isolates from houseflies were positive. The isolated bacteria have variable resistance to frequently used antibiotics in all isolates. Minimum inhibitory concentration values of 15.625 mg/mL for both ginger and lemon extracts, 7.8125 mg/mL for garlic extract, and 0.0313 mg/mL for wasp venom were recorded. Wasp venom has the most potent antibacterial activity compared with the four antibiotics that are currently used in therapies against H. pylori. Conclusion: We conclude that wild houseflies can play a role in disseminating H. pylori. The housefly gut may be a suitable environment for the horizontal transfer of ART genes among its associated microbiome and H. pylori. Wasp venom proved its potential activity as a new and effective anti-H. pylori drug for both therapeutic and preventative usage. [ABSTRACT FROM AUTHOR]

Abstract

This study investigated the antimicrobial activity of body and ovary homogenates of emerging queens of the honeybee Apis mellifera L. Queens'. Fourth-instar larvae were challenged with a sublethal dose of Paenibacillus larvae to investigate the effect against multidrug-resistant bacteria (Escherichia coli 1 and 2 and Klebsiella pneumoniae) and the causative agent of American Foulbrood (Paenibacillus l. l). The agar disk diffusion test was used. Against the selected pathogenic bacteria, both the body and the ovary homogenates showed antibacterial activity. A highly significant change in the antibacterial activities of total body homogenate was detected for treated queens against E. coli 2 as well as K. pneumoniae (0.65 ± 0.02 and 0.65 ± 0.01, respectively) compared with healthy queens (0.45 ± 0.02 and 0.45 ± 0.02, respectively). On the other hand, the ovary extracts of challenged queens showed highly significant increases in antibacterial activity against P. l. larvae, E. coli 1, and K. pneumonia (0.92 ± 0.05, 0.85 ± 0.4, and 0.67 ± 0.0004, respectively) compared with the healthy queens (0.55 ± 0.02, 0.65 ± 0.23, and 0.49 ± 0.001, respectively). These findings could provide us with essential points on the development and production of new antibiotic agents against bacterial diseases. [ABSTRACT FROM AUTHOR]

Abstract

Stichopogon scaliger Loew (Figs 13, 14 D) Stichopogon scaliger Loew, 1847: 501; Stichopogon congener Loew, 1856: 37. Type locality. Italy, ��� S��dlichen Russland ��� [southern Russia]. Diagnosis. Length: Body 5.5 mm, wing 3.2 mm. Resembles S. chrysostoma except for: setae on abdominal tergite l stronger, tufts of hairs on 8th sternite of female short and not touching in the middle; male genitalia with dististylus wider and less curved. Local distribution. Western Desert. Geographical distribution. Bulgaria, Czech Republic, Egypt, France, Greece, Iran, Italy, Kazakhstan, Romania, Russia, Slovakia, Turkey. Specimens examined. Wadi El-Natroun, 11�� 13.IV.2013 (2 &female;) (ASUC). Remarks. This species is recorded from Egypt for the first time. The character of the dististylus of the male in couplet 4 in the key was taken from Theodor (1980) as we do not have a male specimen of Stichopogon scaliger. Engel (1924) identified this species among the Egyptian specimens sent to him by Efflatoun. In contrast, Efflatoun (1937) re-identified the species as S. chrysostoma (not scaliger), based on an examination of 150 Egyptian specimens, including Engel's specimens, and after comparison with Hungarian specimens of S. scaliger. Also, following our own examination of the specimen which was collected from Ramleh, 17.IX.1921 (PPDD) and incorrectly identified by Engel as S. scaliger, it is clear that this specimen belongs to S. chrysostoma. Both Steyskal & El-Bialy (1967) and El-Hawagry (2011) erroneously included this species from the literature based on Engel (1924), we were recently successful in collecting two specimens of this species from Wadi El-Natroun (April 2013) and so this species is here considered as a new record for our fauna., Published as part of Abu El-Hassan, Gawhara M.

Abstract

Synthetic insecticides cause pollution to the environment. In addition, insects develop resistance toward them. So, there is an urgent need for effective safe alternatives. In the current study, nanoemulsion was prepared from essential oil of Cirtus sinensis by the ultrasonic method. The efficacy of the nanoemulsion was evaluated against larvae of Culex pipiens and compared with that of the bulk emulsion. The mean droplet size of the nanoemulsion was 78.8±14.2 nm with poly dispersity index (PDI) value 0.28. The LC50 for the nanoemulsion and the bulk emulsion were 27.4 and 86.3 ppm, respectively related to Citrus sinensis essential oil. The Larvicidal activity of the formulated nanoemulsion was more toxic than that of bulk emulsion. The results showed that nanoemulsion of Cirtus sinensis EO can be used for control of vector-borne disease Culex pipiens larvae. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: A polymerase chain reaction (PCR-based) assay was evaluated for detection of Trypanosoma evansi DNA in experimentally infected mice and naturally infected camels, sheep and goats using the set of primers TBr1 & TBr2 that amplified 164bp DNA fragment. The results revealed that PCR-based assay was able to detect T. evansi directly from the blood during both acute and chronic phase of infection in all tested animals and in the blood and tissues of intraperitoneally infected mice depending upon the level of infection in the test samples. PCR was more powerful than CATT/T. evansi and mouse inoculation tests, when detected the infection in mice (24h) post infection. Present results show that sheep & goats probably play a role in transmission of T. evansi to camels and supported that PCR could be used as a diagnostic tool for epidemiological studies on T. evansi in Egypt.

Abstract

Background: High frequency of Helicobacter pylori infection and the unknown mode of transmission prompted us to investigate H. pylori -wild housefly relationship. H. pylori causes chronic gastritis, peptic ulcers, and stomach cancer. H. pylori persists in the gut of the experimentally infected houseflies. The existence of H. pylori strains isolated from wild houseflies, on the other hand, has never been documented. Materials and Methods: In this study, 902 wild houseflies from different sites were identified as Musca domestica , then 60 flies were screened by traditional microbiological techniques and H. pylori -specific 16S rRNA gene. The antibiotic resistance (ART) was investigated phenotypically. Wild housefly gut bacterial isolates were further evaluated genotypically to have 23S rRNA gene mutation related to clarithromycin resistance. To find efficient therapeutic alternatives, the potency of three plant extracts (garlic, ginger, and lemon) and the wasp, Vespa orientalis venom was evaluated against H. pylori . The cytotoxic effect of the crude wasp venom, the most potent extract, against Vero and Colon cancer (Caco2) cell lines was investigated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Results: All isolates from houseflies were positive. The isolated bacteria have variable resistance to frequently used antibiotics in all isolates. Minimum inhibitory concentration values of 15.625 mg/mL for both ginger and lemon extracts, 7.8125 mg/mL for garlic extract, and 0.0313 mg/mL for wasp venom were recorded. Wasp venom has the most potent antibacterial activity compared with the four antibiotics that are currently used in therapies against H. pylori . Conclusion: We conclude that wild houseflies can play a role in disseminating H. pylori. The housefly gut may be a suitable environment for the horizontal transfer of ART genes among its associated microbiome and H. pylori. Wasp venom proved its potential activity as a new and effective anti- H. pylori drug for both therapeutic and preventative usage.

Abstract

The vaginal washouts from symptomatic and asymptomatic patients were examined by wet mount examination and culture on modified TYM medium. Among the 320 cases examined, 10 were positive for T. vaginalis trophozoites by wet mount examination and culture. Modified TYM medium proved very satisfactory for isolation as well as maintenance of the 10 T. vaginalis isolates. Comparison between the growth patterns of all isolates, by counting the number of viable organisms every 24 hours for 7 days, showed that there is a wide variability in the growth characteristics, as regards lengths of log phase, growth peaks reached, generation times, division rate and number of divisions. Antigenic differentiation of the 10 T. vaginalis isolates through SDS-PAGE demonstrated a total of 34 bands using 10% resolution gel. The bands ranged in molecular weight from 12 to 189 KDa. Most of the bands were common among several isolates while isolate 2 appeared different than other isolates with two characteristic bands; one at 136 KDa and the other at 25 KDa. Also, isolates 4 and 8 had characteristic bands at 163 KDa and 189 KDa respectively.
