Eimeria Infection

Eimeria is an apicomplex protozoon which affects many species of birds, domestic and wild animals including deer. This is the first study in Iraq that was designed for diagnosis Eimeria spp. in deer using traditional methods. Eighty fecal samples of Fallow deer (Damadama) were collected in different provinces in the middle part of Iraq during December 2018 to the end of September 2019. Samples were examined by direct smear and flotation with Sheather's solution. The total infection rate with Eimeria spp. was 70% (56/80), in which higher infection rate was observed in female deer (78%, 39/50). The results also showed that Fawn at age<3-11 months recorded higher rate of infection (86.3%, 19/22). Eimeria infection was more prevalent in Karbala and Baghdad provinces where recorded (73.3% and 72%) respectively, sharp increase of infection recorded during March (87.5%, 7/8). In addition, four species of Eimeria (E. crandalis, E. intricate, E. parva, and E. sordida) were detected in Iraqi deer according to morphological characterization of oocysts. This study highlighted the distribution of some Eimeria species in deer and revealed the effect of some epidemiological factors on prevalence in different middle Iraq provinces.

  Abstract The research was performed in order to investigate the prevalence of  Eimeria spp in buffalo. Coccidiosis, is a common livestock disease include water buffaloes and nothing is known about the most pathogenic species of Eimeria. Since the highest prevalence of oocyst shedding and incidence of disease occurs in buffalo calves less than one year of age. The omnipresent occurrence and negative effects of the infection on health and buffalo growth output are taken into account. Therefore, both farmers and veterinarians should pay greater attention to infections with Eimeria spp. And there is little analysis of data reported in Iraq and the world regarding Eimeria infection in river buffalo spp.

Eimeria Infection

Information on the occurrence, diversity and economic losses due to Eimeria infection on cattle farms is lacking in Western Iran. The principal aim of this study was to determine the prevalence and diversity of Eimeria species in cattle in Hamedan province, Western Iran. In a cross-sectional study performed from June 2010 to April 2013, 400 faecal samples were collected randomly from animals without clinical signs from different cattle farms of Hamedan province and examined for Eimeria species infection using parasitology methods. The overall infection rate of Eimeria species was 8.25%. Nine species of Eimeria were identified including: E. bovis (23.7%), E. zuernii (19.2%), E. canadensis (12.6%), E. ellipsodalis (11.4%), E. alabamensis (10.4%), E. pellita (9.1%), E. auburnensis (6.8%), E. cylindrica (4.6%) and E. bukidnonensis (2.3%). There were statistically significant differences with respect to Eimeria infection and age group (P &lt; 0.0001, OR = 6), although no statistically significant relationships were found for sex (P = 0.35) or faecal consistency (P = 0.587). In conclusion, this study is the first to report the prevalence and diversity of Eimeria species in cattle in Hamedan province. Infection with pathogenic Eimeria spp. was asymptomatic in all animals; this is the reason for the transmission of infection by carriers in this region. Therefore, integrated strategies should be utilised to prevent and control Eimeria spp. infection on cattle farms. &nbsp;

The prevalence of Ostriches cryptosporidiosis was determined for the first time in central and south parts of Iraq to study the effects of age, sex and months on the infection rate and to record the morphological characterization of Cryptosporidium spp in Ostriches. A total of 200 Ostriches fecal samples were examined by traditional methods for detection of the parasite. The total infection rate was 11% (22/200), and the highest infection rate was 12.26% (13/106) in chicks ( 9 months), while the lowest infection rate was 9.57% (9/94) recorded in the adult (> 9 Months). The study included seven provinces in the central and south parts of Iraq: Wasit, Baghdad, Babylon, Diyala, Karbala, Al-Najaf and Al-Qadisiyah. The highest infection rate was reported in Al-Najaf (23.53%) compared with the lowest rate (0%) in Wasit province. March reported an infection rate of 50%, while the lowest rate (0%) was registered during the summer months: June, July and August with a significant difference (P0.05) among months of the study. Morphologically, the study indicated the wide spread of Cryptosporidium parasites in Ostriches in both central and south area of Iraq

Eimeria Infection

Faecal samples were collected from a total of 11 calves on three dairy farms (four from two farms and three from one) where calves generally thrive well and no anti-coccidial treatment is habitually carried out. One of the farms keeps calves in groups on hay/straw bedding, one keeps calves in pairs on plastic slats and then in groups on concrete slats, and the third one keeps calves in groups on concrete slats. Faecal consistency and the total number of Eimeria spp. oocysts per gram faeces (OPG) were determined and species identification was carried out by morphology. Eimeria oocysts were detected in all calves at some point of the study period, and diarrhoea was seen in 55% of the calves. The highest peak in oocyst excretion was 69,300 OPG. The first peak in oocyst excretion was seen 2-3 weeks after calves had been moved to group pens, and a second peak was seen 2-3 weeks later. Nine Eimeria species were found, including E. bovis and E. zuernii. The results are in accordance with previous studies showing that one of the risk factors for Eimeria infection in calves is entering a group pen where older calves are already being kept.

Eimeria Infection

AbstractA total of 350 faecal samples from unweaned alpacas over 3 months of age were collected from 23 herds in order to determine the prevalence of Eimeria spp. in Southern Peru and to identify the risk factors associated to Eimeria infection in young alpacas. Samples were examined by a flotation technique and the identification of risk factors was assessed by a logistic regression analysis. Sixty four percent of the examined animals shed Eimeria oocysts; herd prevalence was 96%, with an intra-herd prevalence of 60% (range 5.9-100%). Five different Eimeria species were identified, being E. lamae (91%), E. alpacae (87%) and E. punoensis (78%) the most prevalent; E. macusaniensis (35%) and E. ivitaensis (13%) were less common. Mixed-species infections were more frequent (78%) than single infections (22%). E. lamae was the most common monospecific infection and E. lamae/E. alpacae the most frequent association. The geographical area has a significant effect on Eimeria infection rates (74.9% wet Puna vs 37.4% dry Puna) as well as the breeding system (65.1% traditional vs 63.8% modern). In contrast, the sex of the animals (64.6% males vs 64.0% females) showed no influence on the prevalence of infection by Eimeria. The high prevalence found at both individual and herd level and the common presence of highly pathogenic Eimeria species may lead to important economic losses for alpaca breeders and could require the implementation of suitable control measures.

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

The different integrated production systems can directly interfere with its bacterial community. The present study aimed to assess density, bacterial diversity and the influence of dry and rainy season in different integrated and an exclusive production system. The fallow and a native forest area was assessed to. Samples were collected in 2012 March and September. The isolation were carried out into Petri dishes containing DYGS medium. The number of colony forming units (CFU) was counted after 48 hours and. The bacterial density ranged between 106 and 107 CFU g-1 soil. The crop system affected the dynamics of the bacterial community only in the rainy season. The rainy season showed greater density of total bacteria when compared to the dry period regardless of the cropping system. The dendrograms with 80 % similarity showed thirteen and fourteen groups in the rainy and dry seasons. Isolates with the capacity to solubilize phosphate in vitro were obtained from all areas in the two seasons, but this feature has been prevalent in bacteria isolated during the rainy season

Background: Endophytic fungi live in plants’ tissue and can produce the same bioactive compounds as its host plant produces. Syzygiumpolyanthum leaves have known to be one of the antibacterial compound producers. Aim and Objective: This study aimed to characterize morphologically, microscopically, and molecularly the antibacterial-producing endophytic fungi of Syzygiumpolyanthum leaves. Methods: The isolation of endophytic fungi was done by fragment planting method on PDA medium. The antibacterial screening was performed using the antagonistic test as the first screening followed by the disc diffusion test method. The morphological characterization was based on isolate’s mycelia color, growth pattern, margin, and surface texture of the colony, while the microscopic characterization was based on its hyphae characteristics. The molecular characterization of the isolate was done by nitrogen base sequence analysis method on nucleotide constituent of ITS rDNA genes of the isolate. Results: The results found that isolate DF1 has antibacterial activity against E.coli, S.aureus, P.acne, and P.aeruginosa, with the greatest inhibition at 10% concentration of broth fermentation extract on S.aureus with a diameter of inhibition of 13.77 mm. Conclusion: Based on macroscopic, microscopic, and molecular characterization, DF1 isolate is similar to Ceriporialacerate.

In the current work, the characterization of novel chitosan/silica nanoparticle/nisin films with the addition of nisin as an antimicrobial technique for blueberry preservation during storage is investigated. Chitosan/Silica Nanoparticle/N (CH-SN-N) films presented a stable suspension as the surface loads (45.9 mV) and the distribution was considered broad (0.62). The result shows that the pH value was increased gradually with the addition of nisin to 4.12, while the turbidity was the highest at 0.39. The content of the insoluble matter and contact angle were the highest for the Chitosan/Silica Nanoparticle (CH-SN) film at 5.68%. The use of nano-materials in chitosan films decreased the material ductility, reduced the tensile strength and elongation-at-break of the membrane. The coated blueberries with Chitosan/Silica Nanoparticle/N films reported the lowest microbial contamination counts at 2.82 log CFU/g followed by Chitosan/Silica Nanoparticle at 3.73 and 3.58 log CFU/g for the aerobic bacteria, molds, and yeasts population, respectively. It was observed that (CH) film extracted 94 regions with an average size of 449.10, at the same time (CH-SN) film extracted 169 regions with an average size of 130.53. The (CH-SN-N) film presented the best result at 5.19%. It could be observed that the size of the total region of the fruit for the (CH) case was the smallest (1663 pixels), which implied that the fruit lost moisture content. As a conclusion, (CH-SN-N) film is recommended for blueberry preservation to prolong the shelf-life during storage.
